2 strokes will last a really long time if the person knows what they're doing and keeps up on proper maintenance. They're also much easier and inexpensive to fix.
eh, I'm mainly against 2 strokes because on these kits without vibration mounts they make your dick go numb, and then you can't even feel you've got a woodie.
I figured out it was because it wasn't mounted the full way on because there wasn't enough thread on the bolt, even though it felt like it was snug. It actually doesn't vibrate at all on a nice bike. How-ever I've ridden ones made with walmart bikes and they vibrate like a motherfucker.
i feel like for most people this is a CHEAP means of transportation. If I'm buying a $100 kit I'm not going to spend $200 on a gas tank or $100 on a new sprocket. Maybe for the hobbyist this would be a god idea.
@@YorHighness Yeah I just shortened mine by removing links and reconnecting it via the master link. I heard those things can lean over with time and end up locking up the back wheel and potentially causing a crash. I certainly wouldn't want to crash mine, especially because my engine is on a vintage Murray Baja bike.
I know I'm 4 years late but no fucking way he can lol he said he's "not strong" well I am strong and I immediately tried when he said that. Nope, not even close
I disagree entirely with this video. Spend $100 on JUST A SPROCKET? $200 FOR A GOD DANG GAS TANK? Most of the engine kits ARE $80-$100. Sure, there not designed to be quality products, but THEY ARE CHEAP! The only reason people buy motorized bike kits is because they are cheaper than any other gas powered vehicle. If someone has $500 - $1000 they are not going to spend it on one of these stupid "quality" 4 stroke bikes. YOU CAN BUY A CAR FOR $1000. Most of the bikes people install these kits on are $10 goodwill bikes. This guy is trying to rip you off and promote his business. 2 strokes are just fine. Hell, even the Trabant 601 had a 2 stroke.
I'm trying to rip you off? LMAO! You may want to put a little more effort in to some good ole quality research and paying attention before you go off on a rant. Had you done some research or even paid any attention you would notice that I don't sell anything! So, since I don't sell anything, in fact I actually give some stuff away for free and even pay the shipping, please tell me how I am trying to rip people off, because I'm dying to know! Also if you would do some more research you would find there are a lot of people that spend $500-$1,000 and in some case way more than that! Also, more research would tell you that these bikes even at $1,000 will pay for themselves in one year or less verses this $1,000 car you speak of which will probably last 500 miles before it needs twice what you paid for it in repairs. I'm all for criticism, but do your research before you blast someone.
I got a 96 Ford Ranger for $1000. 5 - speed manual. 136,000 miles. No rust. No transmission problems. Took it to the mechanic and no obvious large problems. Heating, AC, and radio all work. Has a bed liner. Click profile for pics.
@@sampasch3381 gotta check your bolt tension everyday. 2-strokes are great, but they are at the opposite end of the spectrum from "maintenance free" engines.
Yep, had to stop the video once you said four strokes are more powerful. That is an outright non-truth. Nothing can touch a two stroke since it's actually bigger than it is times two over a four stroke. With the right pipe they are silent and rev much faster and much higer. Too much oil and the fuel ratio will go towards air, too little oil and the mixture gets richer because the viscosity changes. If you run the premium oil and get to know it so that you can recognize when it's hot, it's no big deal and I have many hundreds of thousands of miles on them. If it breaks I can fix it in minutes, no one can rebulld a four stroke in less than a hour or so. Ten minutes out in the hills and I can carry an extra engine because they are so light and so cheap. Hell I usually have 55Lbs of tools, so what would an extra 6 pounds mean to me? Nice try, if you can show me a 250cc engine that makes 56 HP like my 2000 Kx250, then maybe I'll hear ya, till then keep dreamin. Nice looking bikes by the way , but please keep the educational stuff REAL.
Yeah I have an TZR 125 lc that runs about 28hp, very safe and reliable. An older air cooled RD 250 that made 68hp on the dyno and can run to about 10500 rpm. Oh and a tomos that could not be any more basic and still makes enough power to drag my 13st to about 47mph with ease.
@@sizzlean9459 The Yamaha 250 air cooked twin I have is 1979 model. Then they went to the lc. I think outside the UK they were called an RZ. Mine has a set of race tunned barrels along with crankcase modifications to match and a pair of 34mm mikuni carbs. The standard carbs are 28mm. I have compression up from 7:1 to 9.2:1 after that the ignition can not cope. Set of allspeed expansion chambers and race baffles So just about double the factory hp. The TZR 250 is an absolute animal and I wish I had one, but my 125 is a Stan Stephens engined deltabox framed TZR125RR sp which can be taken to 33hp. I keep mine on the safe side and realistic numbers. Still hits about 105. Love 2stroke motors! When they start building 4 stroke chainsaws I'll listen. 35cc chainsaw can make about 3hp and run about 11000rpm.
@@anonymousproductions1792 YOu know what, I love riding in the dirt or on the street, I love not having to pedal sometimes and I think we have come to a point where this 2t vs. 4t has just become dumb. Right now we have snakes in office everywhere and they would love nothing more than to delete our ability to do any riding and they don't give a shit whether my ride uses GEET and burns piss and spits out oxygen or what, they just hate all fun and don't enjoy life unless their is a cock in their mouth or ass or at least that is the way I choose to see them. So with that in mind, how bout we just agree to be riding lovers and brothers and give up the argument? All I'm going to say is 50 MPH is hauling ass, I"m not your babysitter and you may have gone that fast and think you know what's up but the truth is you don't know shit until you've wrecked at that speed and here is my advice....DONT. I'm never one to tell someone "that's too fast" I'm just one who has seen too much meat hanging out of compound fracture holes in the skin and so I'll just say a helmet won't help with the compound fractures and actually you might want to be brain bashed and retarded if you get one so be careful and get all your wrecking out of the way on the soft dirt and make sure your breaks work or you've got enough pad on the bottom of your shoes to get slowed down. I just wish everyone would remember that it's not 4t vs 2t, it's us against them and since they are almost all a bunch of whining bitches who always resort to passing laws against us while they ruin the world with all their ways, try not to piss them off for the sake of the rest of us. Try to remember some of us didn't first choice choose this way but had to resort because of troubles our of own causing and so every law they pass against Me can make my life so much harder so always try not to piss off the "normal" people, especially the ones with 20,000 dollar carbon fiber frames, they are the worst and always do the most damage. Make them think we are the most respectful and nicest people by beinug that way and do it for the whole club we have they are not in.
This guy is just mad he can't use the stock kit to get a 45 mph machine that lasts a minimum of 1500 miles. I'd say that's worth every dollar. I love my noisy smelly two-stroke!
We just build one out of a old trashed, 3Times stolen and returned bike, goes 55-60kph it goes faster than a 50cc Scooter, and These Scooter engines are fester than the 4stroke bicycle kit engines
I agree. . We had to nag mom to spend a grand on a dirt bike when we were kids. Not fun but she was happy when the nagging turned to BBBRRAAAAP BRAAP BRAAAAAAP
On the 2nd day God also made 2 strokes, one to intake and compress, one to ignite and exhaust, and God saw that it was good, and so it was... very good!😂
psymetal It's the classic question of, do you want to spend more right away on something good, or more down the road on repairs and new parts, not to mention down time.
+Sinister Custom Cycles I prefer two stroke bike kits because of their price, I don't ride my bike long distances so breaking down is not a problem, nor do I care for how long it lasts(I spent 120$ on my kit)
It's best to save till until you can afford one of my Harley Bee 2 strokers or one of this guys bikes. And never forget about Freddy at CR MACHINE. I use his stuff here people ask me for his parts and stuff. This man makes a lot of sense the same exact words are in my Harley Bee videos. I prefer the 2 strokers however cheaper to repair easier to get parts from guys like me answer our phones and e-mails asap. If ya need it we get right out to ya if it's in stock... Our bikes are not cheapo Wal-Mart bikes and our bikes are not cheap period I spend on the average $300 to restore older heavier bicycles see my videos even my latest ones this month last month same words. Also the words NOT CHEAP repeatedly...
Whoa!! Somebody wants to sell expensive bicycles!! Iive got a 2 stroke kit, it was fun put in it together. yeah it needs some manteinance to be running ok, but I like taking care of my bike so I dont mind, it's my weekend hobby. 2 strokes are fun and you can upgrade and modify almost everything on it, you can't do that with a 4 stroke. so far my motor is running fine and my bike is so much fun
True this guy has no clue what he is talking about. 2 strokes are actually more quite and have 2x the power of a 4 stroke. I'm 12 years old and I can rebuild the top of an engine. This guy shouldn't say things that he doesn't know about.
every 2 stroke gas bike I see around here are leaky, messy, noisy, and smokes a lot. My 4 stroke is 4 years old and it is as clean as the day I put it on. It runs better than any of the 2 stroke kits. Much more reliable. Mine starts very easy even after 4 years. The same cannot be said of 2 strokes. They are basically made out of cheap pot metal. I know. My first build was a 2 stroke. It was constantly falling apart when I was riding it due to excess vibration. The internal flywheels are not balanced and the cheap needle bearings on the crank and in the piston fall to pieces and literally destroy the engine. I've had people with 2 stroke setups around here beg me to help them build a 4 stroke setup because they are far more reliable and require much less maintenance. 2 stroke bike engines might be smaller, lighter, and have more power but these are not well designed at all. And the quality of the engine is very bad. Almost like a use for a few months then throw away. I can vouch for what this guy is saying because i've had both 2 stroke and 4 stroke kits. Out of the box the 4 stroke setup is much better due to the reliability. My 2 stroke setups were leaky dirty, greasy and very noisy.
I recommend people build a bike with the cheap kit, run the crap out of them and upgrade parts as they see necessary. definitely don't go out and get "quality" parts for your first build. This guy is a die-hard enthusiast that is invested into the hobby at a level that many people will never be. Go out and enjoy your bikes and don't let snobby enthusiasts tell you otherwise.
Snobby enthusiasts? If building a quality bike from the start to show others what the possibilities are have a quality dependable bike from the start makes me that, then I guess I'm guilty. So I'm guessing you buy a cheap car and repair as you go? Maybe a cheap house? Maybe a cheap $8.00 pair of Velcro shoes and then just glue them together as needed?
Those aren't even comparable because they aren't hobbies. You wouldn't buy a cheap house to test wether you'd get into the hobby of owning a house... duh. But I WOULD buy a cheap fishing pole to see if I would get into the hobby of fishing.
Been building for 13 + years man. The cheap 2 stroke kits go forever if you know what your doing man. The cheap 2 strokes are almost bullet proof, you can mix the gas with filtered used oil and they work. I've never had one fail. Everyone knows the hardware in the kits are crap. I've never had an issue with rear sprockets. I've had plenty of issues with cheap rims. Never warped a sprocket. Never had a tank leak. I've got these things to work and ride reliably in -40 with studded tires in the winter. The cheap 2 strokes. Hub mounted sprocket adapters do work better, but not required. If your spending over $300 to build a reliable motorized bicycle. You do not know what your doing. And you don't know what your talking about. If your gonna spend the $. Buy a motorcycle.
A reliable, Japanese engine alone, two or four stroke, costs $200+. The sprocket adapters that come with the kits are unsafe, unreliable, and very hard or impossible to adjust properly. The clamp on adapter is well worth the $75. A quality bicycle that's safe to use with a motor (disk brakes at the very least) is going to be at least $300. Yes, you can build one for under $300, but it will feel like a yugo compared to a corvette. And by the way, a decent cheap motorcycle will cost twice as much as a bike built using the components I mentioned, and you have to register and insure it, and get a license.
I honestly didn't watch the video, but was trolling the comments since I saw evidence of another 2 stroke basher so I couldn't resist joining in. All I know is I am no mechanic, actually a retired old disabled burse, and I decided to see if I could build one of these. So since them I've built around 20, and sold them locally. So all I know is you can get a decent quality used mountain bike cheap, tune it up and buy a kit from one place and for about $200 you get what you see, a bike that you can take anywhere, is rock solid dependable, and when properly tuned with jetting and fuel and the rest will hit an honest gps 52mph on flat ground, (at the end of video, and the very end on the last street was 0- 44mph in only about 3 blocks) the engine is a YD100 with banana pipe, 7.5mmjet, C-clip at highest(lean) setting, 93Super premium gas obtained from a small local airfield, (yes it does make a big difference, regardless of what they say) and a 32 tooth rear sprocket, except for opening the end of banana pipe to 1 3/4 buy just sawing it off, bike is a Diamonback Outlook mountain bike I bought for $50, kit was $159 to my door and after rding it for 3 moths I sold it for $550 and the owner is still flying around on it, no disrespect, js...but it never happened if its not on video right? ."ttps://th-cam.com/video/UWt1lLTgJM4/w-d-xo.html
the two stroke kits require the individual to be somewhat mechanically inclined and have the ability to modify parts of the kit to make it work. In my opinion, you get more bang for your buck with 2 stroke kits.
I actually just purchased a cheap 80cc 2 stroke engine kit and some accessories for it for my 29 inch Walmart bike that cost the same as the engine kit, $120. I have seen so many positive reviews for them it's insane and I just had to pull the trigger and get one to install to see what it's all about. I think initial break in is very important, just as important as regular maintenance, for engine longevity. A lot of the complaints seem like lack of maintenance and know-how. Other complaints seem to be from poorly informed installations. I've seen an expensive kit put together by someone I knew (well over $200 kit...) and the fuel line was laying on the cylinder head... I think the bottom line is education with these installs and spending money in the right places depending on usage. You do make some very valid points about cheaply put together kits and listed some parts I didn't know existed for these set-ups, but some people don't have the money to spend more and need cheap, go anywhere, transportation. For me this build is just a toy. I will ride it the very short distance to work and back and some light trail riding if I trust it not to strand me. Eventually I'll build my own 4 stroke engine brackets to install on a bike I plan on keeping, but that'd cost around, if not more than, $750. Not worth it unless I like it since I can pick up an SSR 110cc dirt bike for the same price. This is a very good and informative video though. I subbed to your channel and look forward to watching your other vids.
i agree i know people who have put it on there walmart 80 dollar bike and didnt have any frame issues unless you try to drive them like your in a motorcross rally now thats a different story a two cycle is better but everyone has there own preference now i am not saying this guy is wrong but i believe the two cycle is the way to go especially when there are performance parts that are more availabe now also if you run a 4 stroke wide open all the time vs two stroke, two stroke wins because it's designed for higher RPM vs four stroke either way i dont see much benefit with the 4 stroke engine unless you get the jack shaft kit, and for some reason this guy has to trash other builders just to gain business so evan johnson i am with you.
+Andrew Sybert yes but it takes time to mix the fluids, they have an average recomended ride time of 30 minutes, the are loud and squealy while four stroke is just put gas in has 60 min recomended max ride time and has smoother rides along with being a low, rumbling noise.
+Andrew Sybert yeah thanks all you have to do is make sure everything's tight , greased, and oiled and your good. Companies allways talk crap about other companies to make more money I work on this kind of still all the time from atv, dirt bike, and cars so all you do is need to make sure everything is on perfectly and take good care of your equipment
Dude all I heard was you downing someone else's work and the quality of things. Well I hate to tell you but I own I motorized bike and yes its a 2 Stroke and you know some people cant AFFORD A $1000 DOLLAR DAMN BIKE AND PARTS SO SHOVE IT
This guy is right about some of the things but honestly for under $300 you can have an amazing miniature 2 stroke chopper. Parts: $80 Walmart Cranbrook huffy bike $120 2 stroke kit from Amazon (shipped with prime) $40-50 CNC rear hub sprocket mount $15 engine mounted spring chain tensioner For a bit more cash you can add some performance mods. $50 high compression head $50 expansion pipe exhaust $20 boost bottle (kinda iffy on this mod) different sprocket sizes etc. Porting and polishing the 2 strokes for more power is easy, so honestly its a fun hobby grade mode of transportation, but you kinda have to do some research before you get into it, the info is all on the interwebs. This is my exact setup and its been running strong for almost 3 years now.
Anyone who trusts their life to a coaster brake, especially a shitty huffy one, is insane or suicidal. Disk brakes, or at the least quality caliper brakes, are a requirement for a motorized bike. There's a reason no e-bikes have coaster brakes.
These "custom bikes" cost thousands of dollars (why wouldn't you buy a real motorcycle instead?? I can easily find a used motorcycle for under $1000.) You forgot to mention how easy it is to work on 2 strokes. 2stokes dont mess with valves or cam systems or any of that crap like the 4 strokers do. The whole reason why 2 strokes are better is because they are so SIMPLE and cheap. If something catastrophic happens to my 2 stroke engine, no biggie, ill buy a whole new one for $150 bucks... Final verdict, For the same price as those "custom bikes" i could have a nice REAL motorcycle AND a nice little 2 stroker bicycle.
Dude dont you think that you are just a very regular user of your motorized bike ? I want to use my cheap one just a few times a month , why would I pay more for a not regular use?
I have been playing with these engines every sense i was big enough to push a lawn mower! They're not Rocket science at all. With a Walmart Bike and a little common sense they will work just fine. Although a hub mounted Sprocket is a very good idea. (IMO) With little to no budget You can build a Two Stroke that will run just as good if not better than a four stroke and have a LOT OF FUN in the process!!! I have seen two strokes smoke less then some four strokes as well... Safety and common sense is key!!!
+Kirby Actually I'm not selling bikes so "bashing" is quite irrelevant. Stating facts based on subscriber emails and seeing issues first hand of people I know is again simply stating facts, not "bashing".
i bought a $145 dollar one and it breaks down everyweek, they all do the parts are under $20 so its ok but not something you can depend on , and mixing oil
I found a free bike and bought 2 47cc 2 stroke engines for 60 bucks, couple hours welding and having fun later and i have a motorized bike... 58kph (36mph) have a lot of fun driving it, burnt the crap out of the clutch and took the clutch off and made it straight to the crankshaft. I mounted it to my rear wheel on top. Greetings from the netherlands
2 strokes are for enthusiasts, who love to work on them. 4 strokes are for noobs who just want to get from A to B. If you know what you're doing, and you like to go fast, 2 strokes are the way to go.
sorry most of the 4-stroke kits have a higher top speed and last 2-3 times longer without the cost of oil and upkeep the 2 cycles always end up costing more in the long run.ting ding ding ding
I had multiple two strokes I ran for five years or more and simply sold them to build something new. They run great as long as you take care of them. Plus I wasn't a "tuner" that wanted to get 50 mph out of it either. Reminds me of a moped forum I used to visit and looked down on these engines like Lego purists do on Lepin.
I have a 2010 2 stroke 80cc and still running strong, had it stored away for almost 2 yrs, took it out an still runs strong. Blow them 4 strokes out of the water.
Your use of your bike is to "blow them 4 strokes out of the water"? Maybe you should be fighting ISIS instead?? Besides, who wants to ride any bicycle in the water? Swim or snorkle or scuba instead. Get real....
Built mine out of a real Indian bike frame. Welded trusses on the fork, fabbed up my own motor mounts, moved the seat, welded up a fuel tank and instant and board tracker! it’s a 4 stroke, complete with an air filter made out of a soup can. Lol I will say, I learned real fast to ditch the rag joint and get the adapter. The 114 year old rims wouldn’t hold a tune, so I replaced them with a set of 11 guage spokes rims. Got rid of the 44 tooth sprocket for a 40. Better but still not great. Running a 36 tooth now and it’s awesome. The WORST thing in the whole kit is the chain tensioner. I ended up welding a small block Chevy alternator bracket between the chain and seat stays. Ride it to work every day! Cheap to run and a blast to drive
I think most builders seeming to forget that this is a bicycle! not a motor cycle...and only a assisted one at that.I also think you should not but down other builders its not your place just looks tacky!!..but agree you should point out why you do what you do etc..
Lawrence Harasim I completely agree I may have been walking a fine line between explaining what I do, and putting someone's work down. However when it's a safety risk to someone making false claims, I felt compelled to direct attention towards his page in hopes of if enough people point things out he may consider putting a little more effort in to his builds. Agreed! People are pushing these bikes way too much. You're going to like the next build I'm starting soon lol.
Thank you for the video. I'm 64 yr old female, 6 mo new to this, with some electrical n mechanical skills. Wanted to get around n enjoy not having to pedal/drive/walk n save $. Bought my 1st 2-stroke on CL $600. I'm on my 2nd bike, the1st got stolen. Wish I had seen this video before I got into this. Loved both bikes, but the constant breakdown (within weeks after purchases) of the cheap Chinese kit on Huffy frame + part replacement have been a Huge Turn-Off. Constant tweaking: wheel bearings, alignment issues, trottle cables, mag nettles, leaky gas tanks, saggy chains, wheel true'ng, muffler almost fell off, inconstant power, black box replacement... the list goes on n on.
I got a $100 48cc 2-stroke kit. If I didn't have a $30,000 automotive education, I wouldn't have been able to keep it running for more than a month or two. A full rebuild and $400 dollars later, I have an awesome setup. It's very reliable, and goes 35mph on level road. I've even had it going 47mph downhill! 😃
built a motorized bike with an old $80 specialized rockhopper from a garage sale, same wheels, same hubs, same everything. put a $110 90cc 2 STROKE motor on it from a sketchy website from china, the same one that gives you shivers. with a rich gas mixture and a poorly tuned carb that thing ran for over 2 years having overheated numerous times in the summer and beaten numerous times in the winter; and it was a BLAST. i rode that thing everywhere, probably had over 300 miles on it. i never maintained it once. not even a spark plug, yet it chugged along just fine, none of the problems you described. towards the end it was struggling to idle but didn't seem to have lost power. it finally died when i lent it to a friend and he cooked it for 4 hours straight in 90 degree weather because he didn't know what he was doing. when i got it back it was still trying to turn over despite all the seals being gone, piston rings gone, and lower end bearing noise like crazy. so it probably had another year left in it. not a single crack on the frame on the 'unfit' bike, the rubber mounted untrued hub never had problems, the chain despite having stretched a ton didn't come off when i tightened the tensioner, and no catastrophic failure in the clutch housing. that thing costed 4 bucks to fill including oil and ran on the same tank for a 4 days. the tank was about a quarter gallon because it took a quarter of the 1 gallon tank to fill. so 1 gallon in roughly 2 weeks. even with how much i beat on it. over all, it was worth the 200 bucks 10 times over. if you're thinking about building one, do it. just make sure your exhaust clears your pedals before the first ride. if it doesn't, just bend it to size! then you got the most fuel efficient, eye catching, 'reliable,' and cheap contraption on the road. if you do decide to dump a grand into though, more power to you! even better.
Right about everything except...except the 2 vs 4 stroke thing....your gonna pay a lot more to make a 4 stroke come even close to a 2 stroke. This guy claims to be an expert...he should learn more about engine building first...anybody can bolt expensive stuff together. 2 stroke engines are more for people who know what they're doing. ANY idiot can run a 4 stroke....but you have to have some engine experience to mess with 2 strokes...mine is a well tuned...non oil leaking 4 stoke smoker...I eat 4 strokes all day long...any time you wanna race those slow...low rpm 4 strokes...come on down
I recently got a "cheap" build 80cc 2stroke for free from a buddy not to mention this is on a 80$ Wal-Mart bike with no shocks I love it for now and it has got me inspired to upgrade and do a build of my own and this video has given me a lot of insight on how to do it right, thank you 👍
I wanted a 4 stroke originally, but a 4 stroke 80cc motor is sold out EVERYWHERE, and I just cant have the wimpy 49cc one that goes a maximum of a mind blowing 15-20 mph! No way! so fast! I guess I'm settling for the 2 stroke that I already bought because of inconveniences, fuck me.
+Zach Campbell Good morning! So there is no doubt about it that 2 strokes have more power and they are the Honda Civic of engines in terms of modifications. As far as 4 strokes go though I have always got 30-33MPH top speed. Now there are different sprocket options out there that will give you low torque and higher top speed like the speeds I mentioned above or a bigger sprocket will give you high torque for hills and such but lower top speeds at about 21-23MPH. Depending on your mechanical aptitude there are other possible options too. If you have any questions you can either email me at sinistercustomcycles@gmail.com or Facebook.com/sccmn. Thank you for your message and support!
Sinister Custom Cycles What also sucks, is my kit didn't even come with the sprocket plates the half moon ones, I have the 3 piece side but not the 2 piece side, I just tightened it with 3 piece and just the tightened nuts on the other side and it seems to be holding up just fine
+Zach Campbell Oh wow, that's not good at all. I would definitely keep a close eye on that. I can't believe that someone hasn't come out with a kit where you don't have to throw 90% of the crap away. I would love to see a kit that had all higher end parts for people.
Me too, I can't even find it where to buy on the Internet since many different websites call it different things, half moon backing plates, 2 piece sprocket clamps, 2 piece 9 hole plates, if the chain comes off at 30 miles per hour and kills me, it's all on that guy from ebay who is selling an unbranded 2 stroke motor that appeared legit with 5 star reviews and a top seller sticker
+Zach Campbell Hey why don't you email at sinistercustomcycles@gmail.com and then later tonight I'll reach out to some of my suppliers and see what I can find for you.
Snob. I own a motorcycle for performance, dependability, etc. Motorized bikes are for fun and to goof around. 10,000 motorcycles are better than watever "super" motorized bike you want to make or sell. You don't get motorized bikes.
so what people cant make a living making 2 stroke bikes? so do people make TH-cam videos about your work or job? people always trying to one up someone.
+Matthew Easley I'm pretty sure I never said that no one can make a living making 2 stroke bikes. I'm also pretty sure I was stating facts from subscribers messages and emails from their experiences with a wide array of engines, especially the 2 strokes. Just like with everything though you cannot please everyone unfortunately. When people are putting the cheapest parts available together and then someone puts the highest end parts then they are suddenly the bad guy. I build my bikes to the best of my ability and my next builds coming soon will raise the bar even more. I don't sell them, or claim to be an expert in anything, I just build my bikes my way and try to share that people in hopes that will help someone.
Love that CNC sprocket adapter design. For sure looks allot better than the kit crap. A Honda GX50 engine & a CNC sprocket adapter is what I'm thinking of doing on my next build using an old local bike shop beach cruiser from the late 90's when bikes were made practically bulletproof. The tricky part would be installing a clutch adapter to work with a Qmatic transmission from EZ Motorbikes which I prefer more than the Grubee crap. But Honda engine + Qmatic transmission + CNC sprocket adapter + good solid bike made in ether Japan or America (local bike shop bike from 80's 90's or early 2000's) = a very reliable build.
I bought a 200 canadain dollar 2 stroke bike it's a trek brand bike and a unbranded chinese 2 stroke bought it's a week ago looks really good fun to ride no issues so far the bike is worth 1300dollars and I got a absolute steal on this thing and the guy who built is has sold about 2 to 3 hundred of these things not all high quality bikes but he sold his last one to me for a great deal as he want to do electric so I'm happy with them and encourage any one to buy 1 I'm 15 so cant drive yet and it goes up theses massive hills we have here in western Canada
*Whats a good affordable 4stroke engine kit to buy?? I have an old worksman I wanna put a motor on. I have a couple 2-strokes its time for me to try the 4stroke for cruisin'*
Pschh 2 strokes are the shit. So much more power than a four stroke given the same displacement. Lol, and getting the gas oil ratio right is hardly rocket science. Noisy yeah, but who cares (except the neighbors lol)
i have 2 china 2 strokes they always break but parts are under $20 and my 4 stroke which hasnt broke yet and is 4 years old, i can depend on the 4 stroke for hot days and going t work but the 2 stoke is like gambling , but fun , it could always break down the 2 stroke
Just like a lot of other things in life there are different levels of quality. All Walmart sells is cheap and a lot of times dangerous bikes that people think are good. Open your mind. You don't have to buy a $2000 bike to get a good bike for you But, don't buy a $100 cheap Walmart bike. You will thank me. Go to a bicycle specialist (bike shop) But be carful some bike shops give other shops a bad name. Small mom and pop ones do well.
Please don't call yourself a "professional" at building motorized bikes, no one is a professional at this, your just putting a f*cking 100 dollar weed wackier engine on a 100 dollar Chinese bicycle, think about that, Btw this video is biased against 2 strokes and people who build these for fun.... long live two strokes
I do also note you caught the 2 stroke Prejudice here. 2 strokes are more powerful for size and volume. They can be muffled so they are not loud like dirt bikes. They are simpler in design and weigh less. Also if you know what you are doing they can be tuned to squeeze more power from them without having to bore and stroke them. They also are easier to mount to a bike. YOU sir must be a fellow 2 stroke owner! Ride to live, live to ride, and have fun doing it!
Regarding stress on the spokes - the spokes of a drive wheel are always stressed, because they're transmitting power from the hub to the rim. This is why bike drive wheels aren't radially spoked, they need crossed over spoke lacing to prevent the hub twisting around in the wheel. The cheap kits' rag joint sprocket fitting is exactly the same as the hub mounted sprocket in this regard. It's likely to be stronger even, because it's bracing mid way up the spokes, effectively turning that side of the wheel into one with a very tall flange hub. lack of chainline adjustment isn't strictly true either. If you get a second set of the rag joint plates you can space the sprocket out using ordinary washers. The problems with this setup come from bad install and maintenance. Always replace the included nuts and bolts with high grade ones and make sure to keep them tight. "grinding the plates" etc isn't something you need to do with an ordinary low flange hub.
+kan't be Good morning! Thank you for the comment! I'll actually be doing a new video with my new builds very soon (November 2016) regarding a comparison of install, strength and long term benefits of a hub mounted adapter and avoiding or at least drastically reducing broken spokes under normal use. Feel free to also follow SCC on FB at Facebook.com/sccmn
The day I spend money for builds similar to the ones at the 7:00-ish mark, I'd rather buy a decent, used but well maintained motorcycle. A stock motorcycle would truly be a "professional build" and with insurance, speed that matches other road vehicles and proper signal lights, it would be much safer than any modified bicycle could be.
I’ve had my 80 cc two stroke on a huffy for like 3 to 4 months and basically drove to work everyday had no issues other than tightening bolts over time I have 120 bucks into my bike I would recommend 10 out of 10 but to each there own
i think those are some really good, well thought out points, but I feel like most people who are buying cheap Chinese two-stroke kits are not buying them to be the best, they are buying them to have a fun time without spending too much money. Its great that you probably have a lot of money to go spending on really nice, hand-built engine kits, but for probably a lot of people, they don't have that kind of money to go spending on professional motorbike kits.
Most folks seem to want something for nothing - at least that is what I am seeing from responses here about 2 strokes and cheapness.... They do not care about longevity nor about pollution Just cheap - and max fun. So be it.
2 strokes require daily attention. every single ride you need to do a bolt check. the sprocket is the weak point. i built one and drove over 400 miles. sold it. and the kid who bought totally destroyed it. i showed him exactly what to check for but he ignored my suggestions. i installed fat tires on my next version and this bike handled better. absorbed more road shock. also used thread lock. definitely best choice i ever made.
for those who are thinking about getting into motorized bike....don't listen to this dude. might as well better off buy you a scooter and save your precious time and your hard earn money.
I spent about $600.00 on a new Walmart Beach cruiser and fitted my 49cc Grubbee 2 stroke engine kit to it. Had to add a spring loaded chain tensioner and better quality chain, but she's got over 1500 miles on her and going strong after 10 years:)-John in Texas
I don't disagree that you shouldn't be cheap especially with the speeds these bikes go up to but some these parts you mentioned are just not in the budget for most people. I did a solid bulletproof 2 stroke build from scratch doing all the cutting and welding to the frame and fork myself and still spent $1200. That was also getting extreme discounts off parts from a friend that owns a bike shop. You and I might have the means as hobbyist but the "funnest" part is the indestructible build that didn't destroy your budget. You have to remember these are just bicycles at the end of the day and if your local legislators allow them they usually have strict laws to follow.
One thought guys. I work in the medical field. If your cheap bike breaks up at 20 to 30mph you are going to get hurt. For every 10mph you are traveling, it like falling 1 story high. Example: If you hit a tree at 20 mph its like falling off a 2 story house on to the ground. Your hospital bill could be 1000.00 to 50,000 dollars. It is very logical to have a well made bike. I have seen people pay out 20,000.00 from falling off a horse. I get it a 1000.00 is a lot if money. In the long run its the safest way to go and have something that will last you a long time. Its good to have safety conscious people and people that take great pride in their work. Just my 2 cents on the matter. Ride safely.
I have 2 2 stroke bikes one of which still has the original cross-hatching after 3500 miles. 40:1 is the ideal mixture for motorised bike 2 stroke engines. I have ridden a 4 stroke bike before and to be very honest, i didnt really like it. They have good low end grunt but after about half throttle they bog down. I am jealous of their fuel econemy however
only problem ive ever had with mine was the chain tension pulley, which i fixed by using a rubber sleeve to stop it from migrating down the lower rail.
The spoke clamping type drive sprocket only has one disadvantage in that it can be misaligned, either axially or concentrically.(or both) Either are not good as the speeds increase as the chain can jump off or you'll get an annoying vibration as the wheel turns. However, it does not put extra stresses on the spokes as you suggest. I agree the hub clamping drive sprocket is the better option but it transmits the driving force along the entire length of the wheel's spokes. The closer to the rim the drive force is applied, the less stress there is on the spokes. So in essence, the hub clamping drive sprocket applies the driving force at the same place it would be applied if one were pedaling. The problem is that depending on the motor and the final drive ratio, the motor can end up applying several times the amount of torque that a pedaling human would. Also, yes the Honda clone horizontal engines are more powerful than the little two-stroke kit motors but there is no commercially available way of adapting one to a bicycle without much fabrication work. As I repair these from time to time I also know they weight more than double what a cheap bicycle motor kit weighs. I'm not advocating for the cheap kits, just correcting the falsehood about them being almost as light and easy to adapt to a bicycle. There is a company I know of who tried to make a bicycle kit that uses a Honda clone engine but their product has been hard to get and also proven to be on the "cheap" side. Check them out, they are called Motoped. Again I'm not advocating for them in fact I would warn you to stay away. They are worth a look only to see what is required to adapt a Honda clone engine to a bicycle type vehicle.
Two stroke gives twice the power as a four stroke and it's why 125 cc 2stroke competes with 250 cc four stroke in mx. Two stroke accelerate twice as fast as four stroke and it's why it's only 2strokes in fmx. Four stroke is more durable than two stroke and easier to control the acceleration and that's why all trial bikes has four stroke (except the smallest ones for kids) anyway to get full power out of an two stroke engine you need a exhaust with an expansion chamber or you will loose at least a third of the power and make a lot more exhaust
Your advocating building a quality bike with good parts. I get it. Disagree on your take on 2 strokes. The 2 stroke kits can be reliable if the crappy parts are replaced. 2 strokes can be had that have been improved by sellers. 4 strokes are heavy and can fail if the oil level is not maintained. Not to mention they are bigger. There are chain drive kits that use Tanaka 2 strokes, which are CARB tier 2 compliant. Tanaka is a high quality 2 stroke made in Japan and will outperform a 4 stroke of similar displacement. They are noisy which is a definite draw back. Both motors have their pros and cons.
Missing the point of these bikes. In Australia, many people (my age/teens) love them, kmart bikes and cheap kits are just meant for having fun. Its not meant to be long term ride about.
Used, but like new, Timberlin bicycle from 1995 ($50) and ebay China special 2 stroke 80cc / 66cc bicycle engine kit ($97) and now 4 months in with 700 miles. No failures other than 2 flat tires. I expect long life from my engine but I do not beat on it. Cruising at 20-24mph is the norm for me and I use it to commute to work.
I brought a rear hub motor for a 15+ year old bike brought at Target. Steel frame and I've never had a problem with it. Even I'm surprised this bike has held up this long.
*8:12** "For speed, reliability, torque performance, I put this up against any 2stroke for a MB. BUT I CANT wait to test it out next spring to see its performance" WTF!? 🤦♂️*
I don't know. I've got many, many miles and a good many years of riding on a cheap $100 49cc motor kit with stock parts. It comes down to doing a proper assembly and set up. MOST problems that people have with these things is because they lack the skill to properly build a motorized bike. For under $200 I can have a nice home built motorized bike that will be a lot of fun and last 4 or 5 years, maybe more. For a $1,000 I wouldn't spend on a bike, instead I would use that to upgrade the headlights on my Jaguar or repaint my Triumph motorcycle. There is a point where you can really spend more money on something than it will ever be worth.
these aren’t meant to be professional motorcycles. I look at them as a fun project, maybe for teenagers, or an cheaper alternative to a mini bike. Or, some people use them as transportation, which can be done.. for the prices you are going to, you could buy a moped, or even a salvage motorcycle .
i agree with your views on proper builds how ever i cant agree with you on the castration of '2' strokes, i can't imagine a "4" stroke weed eater, two stroke isn't going away by a long shot.
where would i get the part u talked about.i am sick of buying $200 in spokes for my bike. And the boost bottle whats do you u think about them? I heard they work and they do not. if u could can u do a reviwe on it so i know what i am gettng in to?

Those sprockets aren't that hard to put on!
Yup, pretty easy. I can built the whole bike in 2.5 hours
Exactly
Lol, just can be a little bit of a pain but definitely doable with patience!!!
Me and my dad whose a mechanic built it in 7 hours runs fine this guy is just trying to ruin peoples dreams to make a motorized bike
Yeah it’s not that bad...first time maybe but once you understand it...it’s easy
im sorry dude but i disagree with almost everything you said about 2 stroke engines
eh, I'm mainly against 2 strokes because on these kits without vibration mounts they make your dick go numb, and then you can't even feel you've got a woodie.
I figured out it was because it wasn't mounted the full way on because there wasn't enough thread on the bolt, even though it felt like it was snug. It actually doesn't vibrate at all on a nice bike. How-ever I've ridden ones made with walmart bikes and they vibrate like a motherfucker.
I’ve just figured it out.
2 strokes have their purpose
Nothing wrong with disagreeing with the truth.
The whole point of these kits is to have fun not flush your wallet down the drain

Spot on!
yeah buy most people are to cheap and get a $80 dollar kit and wonder why it breaks down every week, end up spending a fortune
Damn... This guy must of really got his heart broken by a 2 stroke 💔 lbs
Either that or he doesn't understand them, same as he doesn't understand the wheel.
I think he just doesn't understand them, same way he doesn't understand the wheel.
Yea a little but hurt
🤣
i feel like for most people this is a CHEAP means of transportation. If I'm buying a $100 kit I'm not going to spend $200 on a gas tank or $100 on a new sprocket. Maybe for the hobbyist this would be a god idea.
Certain parts need to be swapped out for safety. Rag Joints suck. That cheap chain tensioner is death.
@@YorHighness Yeah I just shortened mine by removing links and reconnecting it via the master link. I heard those things can lean over with time and end up locking up the back wheel and potentially causing a crash. I certainly wouldn't want to crash mine, especially because my engine is on a vintage Murray Baja bike.
Keep that PMA ✊🏼🌲🤙🏻
he says he can flex the sprocket with his hands,,i would like to see him try after its bolted on,, just sounds like a complete hater to me
I know I'm 4 years late but no fucking way he can lol he said he's "not strong" well I am strong and I immediately tried when he said that. Nope, not even close
I disagree entirely with this video. Spend $100 on JUST A SPROCKET? $200 FOR A GOD DANG GAS TANK? Most of the engine kits ARE $80-$100. Sure, there not designed to be quality products, but THEY ARE CHEAP! The only reason people buy motorized bike kits is because they are cheaper than any other gas powered vehicle. If someone has $500 - $1000 they are not going to spend it on one of these stupid "quality" 4 stroke bikes. YOU CAN BUY A CAR FOR $1000. Most of the bikes people install these kits on are $10 goodwill bikes. This guy is trying to rip you off and promote his business. 2 strokes are just fine. Hell, even the Trabant 601 had a 2 stroke.
I'm trying to rip you off? LMAO! You may want to put a little more effort in to some good ole quality research and paying attention before you go off on a rant. Had you done some research or even paid any attention you would notice that I don't sell anything! So, since I don't sell anything, in fact I actually give some stuff away for free and even pay the shipping, please tell me how I am trying to rip people off, because I'm dying to know! Also if you would do some more research you would find there are a lot of people that spend $500-$1,000 and in some case way more than that! Also, more research would tell you that these bikes even at $1,000 will pay for themselves in one year or less verses this $1,000 car you speak of which will probably last 500 miles before it needs twice what you paid for it in repairs. I'm all for criticism, but do your research before you blast someone.
Oh, I almost forgot...Happy Holidays!
I got a 96 Ford Ranger for $1000. 5 - speed manual. 136,000 miles. No rust. No transmission problems. Took it to the mechanic and no obvious large problems. Heating, AC, and radio all work. Has a bed liner. Click profile for pics.
I didn't realize you are not a business. I only assumed this because you act like you have competition. Most people don't spend $200 on a gas tank.

L O L
Ever had the exhaust fall off before? They sound mean then. More powerful too
@@sampasch3381 gotta check your bolt tension everyday. 2-strokes are great, but they are at the opposite end of the spectrum from "maintenance free" engines.
Yep, had to stop the video once you said four strokes are more powerful. That is an outright non-truth. Nothing can touch a two stroke since it's actually bigger than it is times two over a four stroke. With the right pipe they are silent and rev much faster and much higer. Too much oil and the fuel ratio will go towards air, too little oil and the mixture gets richer because the viscosity changes. If you run the premium oil and get to know it so that you can recognize when it's hot, it's no big deal and I have many hundreds of thousands of miles on them. If it breaks I can fix it in minutes, no one can rebulld a four stroke in less than a hour or so. Ten minutes out in the hills and I can carry an extra engine because they are so light and so cheap. Hell I usually have 55Lbs of tools, so what would an extra 6 pounds mean to me? Nice try, if you can show me a 250cc engine that makes 56 HP like my 2000 Kx250, then maybe I'll hear ya, till then keep dreamin. Nice looking bikes by the way , but please keep the educational stuff REAL.
Yeah I have an TZR 125 lc that runs about 28hp, very safe and reliable. An older air cooled RD 250 that made 68hp on the dyno and can run to about 10500 rpm. Oh and a tomos that could not be any more basic and still makes enough power to drag my 13st to about 47mph with ease.
@@sizzlean9459 The Yamaha 250 air cooked twin I have is 1979 model. Then they went to the lc. I think outside the UK they were called an RZ. Mine has a set of race tunned barrels along with crankcase modifications to match and a pair of 34mm mikuni carbs. The standard carbs are 28mm. I have compression up from 7:1 to 9.2:1 after that the ignition can not cope. Set of allspeed expansion chambers and race baffles So just about double the factory hp. The TZR 250 is an absolute animal and I wish I had one, but my 125 is a Stan Stephens engined deltabox framed TZR125RR sp which can be taken to 33hp. I keep mine on the safe side and realistic numbers. Still hits about 105. Love 2stroke motors! When they start building 4 stroke chainsaws I'll listen. 35cc chainsaw can make about 3hp and run about 11000rpm.
What exhaust makes them "silent" without losing power? Having alot of fun with them, but boy are they loud.
Dude but the 212cc and 79cc four strokes can hit 50 something mph easily out of the box
@@anonymousproductions1792 YOu know what, I love riding in the dirt or on the street, I love not having to pedal sometimes and I think we have come to a point where this 2t vs. 4t has just become dumb. Right now we have snakes in office everywhere and they would love nothing more than to delete our ability to do any riding and they don't give a shit whether my ride uses GEET and burns piss and spits out oxygen or what, they just hate all fun and don't enjoy life unless their is a cock in their mouth or ass or at least that is the way I choose to see them. So with that in mind, how bout we just agree to be riding lovers and brothers and give up the argument? All I'm going to say is 50 MPH is hauling ass, I"m not your babysitter and you may have gone that fast and think you know what's up but the truth is you don't know shit until you've wrecked at that speed and here is my advice....DONT. I'm never one to tell someone "that's too fast" I'm just one who has seen too much meat hanging out of compound fracture holes in the skin and so I'll just say a helmet won't help with the compound fractures and actually you might want to be brain bashed and retarded if you get one so be careful and get all your wrecking out of the way on the soft dirt and make sure your breaks work or you've got enough pad on the bottom of your shoes to get slowed down. I just wish everyone would remember that it's not 4t vs 2t, it's us against them and since they are almost all a bunch of whining bitches who always resort to passing laws against us while they ruin the world with all their ways, try not to piss them off for the sake of the rest of us. Try to remember some of us didn't first choice choose this way but had to resort because of troubles our of own causing and so every law they pass against Me can make my life so much harder so always try not to piss off the "normal" people, especially the ones with 20,000 dollar carbon fiber frames, they are the worst and always do the most damage. Make them think we are the most respectful and nicest people by beinug that way and do it for the whole club we have they are not in.

Whoa!! Somebody wants to sell expensive bicycles!! Iive got a 2 stroke kit, it was fun put in it together. yeah it needs some manteinance to be running ok, but I like taking care of my bike so I dont mind, it's my weekend hobby. 2 strokes are fun and you can upgrade and modify almost everything on it, you can't do that with a 4 stroke. so far my motor is running fine and my bike is so much fun
i love 2 strokes, best thing ever made
True this guy has no clue what he is talking about. 2 strokes are actually more quite and have 2x the power of a 4 stroke. I'm 12 years old and I can rebuild the top of an engine. This guy shouldn't say things that he doesn't know about.
every 2 stroke gas bike I see around here are leaky, messy, noisy, and smokes a lot. My 4 stroke is 4 years old and it is as clean as the day I put it on. It runs better than any of the 2 stroke kits. Much more reliable. Mine starts very easy even after 4 years. The same cannot be said of 2 strokes. They are basically made out of cheap pot metal. I know. My first build was a 2 stroke. It was constantly falling apart when I was riding it due to excess vibration. The internal flywheels are not balanced and the cheap needle bearings on the crank and in the piston fall to pieces and literally destroy the engine.
I've had people with 2 stroke setups around here beg me to help them build a 4 stroke setup because they are far more reliable and require much less maintenance. 2 stroke bike engines might be smaller, lighter, and have more power but these are not well designed at all. And the quality of the engine is very bad. Almost like a use for a few months then throw away.
I can vouch for what this guy is saying because i've had both 2 stroke and 4 stroke kits. Out of the box the 4 stroke setup is much better due to the reliability. My 2 stroke setups were leaky dirty, greasy and very noisy.

Got that right!!
I recommend people build a bike with the cheap kit, run the crap out of them and upgrade parts as they see necessary. definitely don't go out and get "quality" parts for your first build. This guy is a die-hard enthusiast that is invested into the hobby at a level that many people will never be. Go out and enjoy your bikes and don't let snobby enthusiasts tell you otherwise.
Snobby enthusiasts? If building a quality bike from the start to show others what the possibilities are have a quality dependable bike from the start makes me that, then I guess I'm guilty. So I'm guessing you buy a cheap car and repair as you go? Maybe a cheap house? Maybe a cheap $8.00 pair of Velcro shoes and then just glue them together as needed?
Those aren't even comparable because they aren't hobbies. You wouldn't buy a cheap house to test wether you'd get into the hobby of owning a house... duh. But I WOULD buy a cheap fishing pole to see if I would get into the hobby of fishing.
Custom doesn't mean the most expensive stuff
Been building for 13 + years man.
The cheap 2 stroke kits go forever if you know what your doing man.
The cheap 2 strokes are almost bullet proof, you can mix the gas with filtered used oil and they work.
I've never had one fail.
Everyone knows the hardware in the kits are crap.
I've never had an issue with rear sprockets. I've had plenty of issues with cheap rims.
Never warped a sprocket.
Never had a tank leak.
I've got these things to work and ride reliably in -40 with studded tires in the winter. The cheap 2 strokes.
Hub mounted sprocket adapters do work better, but not required.
If your spending over $300 to build a reliable motorized bicycle. You do not know what your doing. And you don't know what your talking about.
If your gonna spend the $.
Buy a motorcycle.
A reliable, Japanese engine alone, two or four stroke, costs $200+. The sprocket adapters that come with the kits are unsafe, unreliable, and very hard or impossible to adjust properly. The clamp on adapter is well worth the $75. A quality bicycle that's safe to use with a motor (disk brakes at the very least) is going to be at least $300. Yes, you can build one for under $300, but it will feel like a yugo compared to a corvette. And by the way, a decent cheap motorcycle will cost twice as much as a bike built using the components I mentioned, and you have to register and insure it, and get a license.

the two stroke kits require the individual to be somewhat mechanically inclined and have the ability to modify parts of the kit to make it work. In my opinion, you get more bang for your buck with 2 stroke kits.
My 2 stroke hyper motor went 13,000 miles.A friend put another motor that had 600 miles. I had my motorized hyper 3 plus rears
I actually just purchased a cheap 80cc 2 stroke engine kit and some accessories for it for my 29 inch Walmart bike that cost the same as the engine kit, $120. I have seen so many positive reviews for them it's insane and I just had to pull the trigger and get one to install to see what it's all about.
I think initial break in is very important, just as important as regular maintenance, for engine longevity. A lot of the complaints seem like lack of maintenance and know-how. Other complaints seem to be from poorly informed installations. I've seen an expensive kit put together by someone I knew (well over $200 kit...) and the fuel line was laying on the cylinder head...
I think the bottom line is education with these installs and spending money in the right places depending on usage.
You do make some very valid points about cheaply put together kits and listed some parts I didn't know existed for these set-ups, but some people don't have the money to spend more and need cheap, go anywhere, transportation.
For me this build is just a toy. I will ride it the very short distance to work and back and some light trail riding if I trust it not to strand me. Eventually I'll build my own 4 stroke engine brackets to install on a bike I plan on keeping, but that'd cost around, if not more than, $750. Not worth it unless I like it since I can pick up an SSR 110cc dirt bike for the same price.
This is a very good and informative video though. I subbed to your channel and look forward to watching your other vids.
My 2 stroke has done over 10,000 kilometers.It is excellent.My the correct oil mix there is very little smoke.
And what is the perfect ratio?
@@gunesfb1907 20:1
My engine never smokes I use a 50:1 mix with a lil bit of octane boost I go 22 miles a day plus and only have to make minor tweaks love my 2stroker!
I go 30:1 because i want it to last longer.
The noise of a 2 stroke keeps u safer. Had a lady almost pull in front of me til she heard me
This guy just bothers me he says stuff that bothers him we don't need your opinion 2 strokes are really good and aren't really hard to maintain at all
i agree i know people who have put it on there walmart 80 dollar bike and didnt have any frame issues unless you try to drive them like your in a motorcross rally now thats a different story a two cycle is better but everyone has there own preference now i am not saying this guy is wrong but i believe the two cycle is the way to go especially when there are performance parts that are more availabe now also if you run a 4 stroke wide open all the time vs two stroke, two stroke wins because it's designed for higher RPM vs four stroke either way i dont see much benefit with the 4 stroke engine unless you get the jack shaft kit, and for some reason this guy has to trash other builders just to gain business so evan johnson i am with you.
+Andrew Sybert yes but it takes time to mix the fluids, they have an average recomended ride time of 30 minutes, the are loud and squealy while four stroke is just put gas in has 60 min recomended max ride time and has smoother rides along with being a low, rumbling noise.
+NotSoNerdGaming yeah mixing the gas takes a extra 10 seaconds. And a 4 stroke is heavier and aren't ass powerful
+Andrew Sybert yeah thanks all you have to do is make sure everything's tight , greased, and oiled and your good. Companies allways talk crap about other companies to make more money I work on this kind of still all the time from atv, dirt bike, and cars so all you do is need to make sure everything is on perfectly and take good care of your equipment
NotSoNerdGaming I see
Why would you spend more on a bicycle? Rather get a used dirt bike and you’ll have a much greater experience out of it...
Dude all I heard was you downing someone else's work and the quality of things. Well I hate to tell you but I own I motorized bike and yes its a 2 Stroke and you know some people cant AFFORD A $1000 DOLLAR DAMN BIKE AND PARTS SO SHOVE IT
This guy is right about some of the things but honestly for under $300 you can have an amazing miniature 2 stroke chopper.
Parts:
$80 Walmart Cranbrook huffy bike
$120 2 stroke kit from Amazon (shipped with prime)
$40-50 CNC rear hub sprocket mount
$15 engine mounted spring chain tensioner
For a bit more cash you can add some performance mods.
$50 high compression head
$50 expansion pipe exhaust
$20 boost bottle (kinda iffy on this mod)
different sprocket sizes
etc.
Porting and polishing the 2 strokes for more power is easy, so honestly its a fun hobby grade mode of transportation, but you kinda have to do some research before you get into it, the info is all on the interwebs.
This is my exact setup and its been running strong for almost 3 years now.
Anyone who trusts their life to a coaster brake, especially a shitty huffy one, is insane or suicidal. Disk brakes, or at the least quality caliper brakes, are a requirement for a motorized bike. There's a reason no e-bikes have coaster brakes.
These "custom bikes" cost thousands of dollars (why wouldn't you buy a real motorcycle instead?? I can easily find a used motorcycle for under $1000.) You forgot to mention how easy it is to work on 2 strokes. 2stokes dont mess with valves or cam systems or any of that crap like the 4 strokers do. The whole reason why 2 strokes are better is because they are so SIMPLE and cheap. If something catastrophic happens to my 2 stroke engine, no biggie, ill buy a whole new one for $150 bucks... Final verdict, For the same price as those "custom bikes" i could have a nice REAL motorcycle AND a nice little 2 stroker bicycle.
2 strokes only 4 moving parts easy cheap.
exactly
Dude dont you think that you are just a very regular user of your motorized bike ? I want to use my cheap one just a few times a month , why would I pay more for a not regular use?
I have been playing with these engines every sense i was big enough to push a lawn mower! They're not Rocket science at all. With a Walmart Bike and a little common sense they will work just fine. Although a hub mounted Sprocket is a very good idea. (IMO) With little to no budget You can build a Two Stroke that will run just as good if not better than a four stroke and have a LOT OF FUN in the process!!! I have seen two strokes smoke less then some four strokes as well... Safety and common sense is key!!!
7:50 waiting on this engine builds for like a few years now Loading .....................................
There are much better ways to promote your bikes than bashing the compition.
+Kirby Actually I'm not selling bikes so "bashing" is quite irrelevant. Stating facts based on subscriber emails and seeing issues first hand of people I know is again simply stating facts, not "bashing".
Sinister Custom Cycles oh
You're pretty unreasonably biased towards two strokes, there's benefits to both and it's a matter of preference
I literally just bought 105 dollar bike kit and it's been working fine for months, not to mention it's a two strole
i bought a $145 dollar one and it breaks down everyweek, they all do the parts are under $20 so its ok but not something you can depend on , and mixing oil
I found a free bike and bought 2 47cc 2 stroke engines for 60 bucks, couple hours welding and having fun later and i have a motorized bike... 58kph (36mph) have a lot of fun driving it, burnt the crap out of the clutch and took the clutch off and made it straight to the crankshaft. I mounted it to my rear wheel on top. Greetings from the netherlands
2 strokes are for enthusiasts, who love to work on them. 4 strokes are for noobs who just want to get from A to B. If you know what you're doing, and you like to go fast, 2 strokes are the way to go.
sorry most of the 4-stroke kits have a higher top speed and last 2-3 times longer without the cost of oil and upkeep the 2 cycles always end up costing more in the long run.ting ding ding ding
@@unrealinventor2006 lol
I had multiple two strokes I ran for five years or more and simply sold them to build something new. They run great as long as you take care of them. Plus I wasn't a "tuner" that wanted to get 50 mph out of it either.
Reminds me of a moped forum I used to visit and looked down on these engines like Lego purists do on Lepin.
Fyi, "professional" means you make money, doesn't mean you're good at it.
Omg Smokey and noisy? That’s the fun part! Love them Smokey noisy things.
I have a 2010 2 stroke 80cc and still running strong, had it stored away for almost 2 yrs, took it out an still runs strong. Blow them 4 strokes out of the water.
Your use of your bike is to "blow them 4 strokes out of the water"? Maybe you should be fighting ISIS instead?? Besides, who wants to ride any bicycle in the water? Swim or snorkle or scuba instead. Get real....
@@kenpisichko1340
“ and this kids, is what you call a failed attempt at trying to be funny.”
Built mine out of a real Indian bike frame. Welded trusses on the fork, fabbed up my own motor mounts, moved the seat, welded up a fuel tank and instant and board tracker! it’s a 4 stroke, complete with an air filter made out of a soup can. Lol
I will say, I learned real fast to ditch the rag joint and get the adapter. The 114 year old rims wouldn’t hold a tune, so I replaced them with a set of 11 guage spokes rims. Got rid of the 44 tooth sprocket for a 40. Better but still not great. Running a 36 tooth now and it’s awesome.
The WORST thing in the whole kit is the chain tensioner. I ended up welding a small block Chevy alternator bracket between the chain and seat stays.
Ride it to work every day! Cheap to run and a blast to drive
I've done hundreds of miles with the original rear sprocket rag joint setup, no problems at all
A full head and piston rebuild kit cost $20 on eBay and a new carb cost $8 I don't think it's really that big of a deal lol
I think most builders seeming to forget that this is a bicycle! not a motor cycle...and only a assisted one at that.I also think you should not but down other builders its not your place just looks tacky!!..but agree you should point out why you do what you do etc..
Lawrence Harasim I completely agree I may have been walking a fine line between explaining what I do, and putting someone's work down. However when it's a safety risk to someone making false claims, I felt compelled to direct attention towards his page in hopes of if enough people point things out he may consider putting a little more effort in to his builds. Agreed! People are pushing these bikes way too much. You're going to like the next build I'm starting soon lol.
Thank you for the video. I'm 64 yr old female, 6 mo new to this, with some electrical n mechanical skills. Wanted to get around n enjoy not having to pedal/drive/walk n save $. Bought my 1st 2-stroke on CL $600. I'm on my 2nd bike, the1st got stolen. Wish I had seen this video before I got into this. Loved both bikes, but the constant breakdown (within weeks after purchases) of the cheap Chinese kit on Huffy frame + part replacement have been a Huge Turn-Off. Constant tweaking: wheel bearings, alignment issues, trottle cables, mag nettles, leaky gas tanks, saggy chains, wheel true'ng, muffler almost fell off, inconstant power, black box replacement... the list goes on n on.
+Lawrence Harasim Engine on a bicycle = motor cycle
I got a $100 48cc 2-stroke kit. If I didn't have a $30,000 automotive education, I wouldn't have been able to keep it running for more than a month or two. A full rebuild and $400 dollars later, I have an awesome setup. It's very reliable, and goes 35mph on level road. I've even had it going 47mph downhill! 😃
80cc FTW 👍
built a motorized bike with an old $80 specialized rockhopper from a garage sale, same wheels, same hubs, same everything. put a $110 90cc 2 STROKE motor on it from a sketchy website from china, the same one that gives you shivers.
with a rich gas mixture and a poorly tuned carb that thing ran for over 2 years having overheated numerous times in the summer and beaten numerous times in the winter; and it was a BLAST. i rode that thing everywhere, probably had over 300 miles on it.
i never maintained it once. not even a spark plug, yet it chugged along just fine, none of the problems you described. towards the end it was struggling to idle but didn't seem to have lost power.
it finally died when i lent it to a friend and he cooked it for 4 hours straight in 90 degree weather because he didn't know what he was doing. when i got it back it was still trying to turn over despite all the seals being gone, piston rings gone, and lower end bearing noise like crazy. so it probably had another year left in it.
not a single crack on the frame on the 'unfit' bike, the rubber mounted untrued hub never had problems, the chain despite having stretched a ton didn't come off when i tightened the tensioner, and no catastrophic failure in the clutch housing.
that thing costed 4 bucks to fill including oil and ran on the same tank for a 4 days. the tank was about a quarter gallon because it took a quarter of the 1 gallon tank to fill. so 1 gallon in roughly 2 weeks. even with how much i beat on it.
over all, it was worth the 200 bucks 10 times over. if you're thinking about building one, do it. just make sure your exhaust clears your pedals before the first ride. if it doesn't, just bend it to size! then you got the most fuel efficient, eye catching, 'reliable,' and cheap contraption on the road.
if you do decide to dump a grand into though, more power to you! even better.
Right about everything except...except the 2 vs 4 stroke thing....your gonna pay a lot more to make a 4 stroke come even close to a 2 stroke. This guy claims to be an expert...he should learn more about engine building first...anybody can bolt expensive stuff together. 2 stroke engines are more for people who know what they're doing. ANY idiot can run a 4 stroke....but you have to have some engine experience to mess with 2 strokes...mine is a well tuned...non oil leaking 4 stoke smoker...I eat 4 strokes all day long...any time you wanna race those slow...low rpm 4 strokes...come on down
I recently got a "cheap" build 80cc 2stroke for free from a buddy not to mention this is on a 80$ Wal-Mart bike with no shocks I love it for now and it has got me inspired to upgrade and do a build of my own and this video has given me a lot of insight on how to do it right, thank you 👍
I wanted a 4 stroke originally, but a 4 stroke 80cc motor is sold out EVERYWHERE, and I just cant have the wimpy 49cc one that goes a maximum of a mind blowing 15-20 mph! No way! so fast! I guess I'm settling for the 2 stroke that I already bought because of inconveniences, fuck me.
+Zach Campbell Good morning! So there is no doubt about it that 2 strokes have more power and they are the Honda Civic of engines in terms of modifications. As far as 4 strokes go though I have always got 30-33MPH top speed. Now there are different sprocket options out there that will give you low torque and higher top speed like the speeds I mentioned above or a bigger sprocket will give you high torque for hills and such but lower top speeds at about 21-23MPH. Depending on your mechanical aptitude there are other possible options too. If you have any questions you can either email me at sinistercustomcycles@gmail.com or Facebook.com/sccmn. Thank you for your message and support!
Sinister Custom Cycles What also sucks, is my kit didn't even come with the sprocket plates the half moon ones, I have the 3 piece side but not the 2 piece side, I just tightened it with 3 piece and just the tightened nuts on the other side and it seems to be holding up just fine
+Zach Campbell Oh wow, that's not good at all. I would definitely keep a close eye on that. I can't believe that someone hasn't come out with a kit where you don't have to throw 90% of the crap away. I would love to see a kit that had all higher end parts for people.
Me too, I can't even find it where to buy on the Internet since many different websites call it different things, half moon backing plates, 2 piece sprocket clamps, 2 piece 9 hole plates, if the chain comes off at 30 miles per hour and kills me, it's all on that guy from ebay who is selling an unbranded 2 stroke motor that appeared legit with 5 star reviews and a top seller sticker
+Zach Campbell Hey why don't you email at sinistercustomcycles@gmail.com and then later tonight I'll reach out to some of my suppliers and see what I can find for you.
Snob. I own a motorcycle for performance, dependability, etc. Motorized bikes are for fun and to goof around. 10,000 motorcycles are better than watever "super" motorized bike you want to make or sell. You don't get motorized bikes.
so what people cant make a living making 2 stroke bikes? so do people make TH-cam videos about your work or job? people always trying to one up someone.
+Matthew Easley I'm pretty sure I never said that no one can make a living making 2 stroke bikes. I'm also pretty sure I was stating facts from subscribers messages and emails from their experiences with a wide array of engines, especially the 2 strokes. Just like with everything though you cannot please everyone unfortunately. When people are putting the cheapest parts available together and then someone puts the highest end parts then they are suddenly the bad guy. I build my bikes to the best of my ability and my next builds coming soon will raise the bar even more. I don't sell them, or claim to be an expert in anything, I just build my bikes my way and try to share that people in hopes that will help someone.
got ya cool
Love that CNC sprocket adapter design. For sure looks allot better than the kit crap. A Honda GX50 engine & a CNC sprocket adapter is what I'm thinking of doing on my next build using an old local bike shop beach cruiser from the late 90's when bikes were made practically bulletproof. The tricky part would be installing a clutch adapter to work with a Qmatic transmission from EZ Motorbikes which I prefer more than the Grubee crap. But Honda engine + Qmatic transmission + CNC sprocket adapter + good solid bike made in ether Japan or America (local bike shop bike from 80's 90's or early 2000's) = a very reliable build.

Wish I had watched this before I bought a $180 motor kit and a 29" bike from Walmart :(
*Whats a good affordable 4stroke engine kit to buy?? I have an old worksman I wanna put a motor on. I have a couple 2-strokes its time for me to try the 4stroke for cruisin'*
Pschh 2 strokes are the shit. So much more power than a four stroke given the same displacement. Lol, and getting the gas oil ratio right is hardly rocket science. Noisy yeah, but who cares (except the neighbors lol)
i have 2 china 2 strokes they always break but parts are under $20 and my 4 stroke which hasnt broke yet and is 4 years old, i can depend on the 4 stroke for hot days and going t work but the 2 stoke is like gambling , but fun , it could always break down the 2 stroke
Walmart bikes are still good, almost every single bike is made from China. It doesn't matter where you go to get a bike.
Just like a lot of other things in life there are different levels of quality. All Walmart sells is cheap and a lot of times dangerous bikes that people think are good. Open your mind. You don't have to buy a $2000 bike to get a good bike for you But, don't buy a $100 cheap Walmart bike. You will thank me. Go to a bicycle specialist (bike shop) But be carful some bike shops give other shops a bad name. Small mom and pop ones do well.
Please don't call yourself a "professional" at building motorized bikes, no one is a professional at this, your just putting a f*cking 100 dollar weed wackier engine on a 100 dollar Chinese bicycle, think about that, Btw this video is biased against 2 strokes and people who build these for fun....
long live two strokes
Right on. It's just for fun.
I do also note you caught the 2 stroke Prejudice here. 2 strokes are more powerful for size and volume. They can be muffled so they are not loud like dirt bikes. They are simpler in design and weigh less. Also if you know what you are doing they can be tuned to squeeze more power from them without having to bore and stroke them. They also are easier to mount to a bike. YOU sir must be a fellow 2 stroke owner!
Ride to live, live to ride, and have fun doing it!
Regarding stress on the spokes - the spokes of a drive wheel are always stressed, because they're transmitting power from the hub to the rim. This is why bike drive wheels aren't radially spoked, they need crossed over spoke lacing to prevent the hub twisting around in the wheel.
The cheap kits' rag joint sprocket fitting is exactly the same as the hub mounted sprocket in this regard. It's likely to be stronger even, because it's bracing mid way up the spokes, effectively turning that side of the wheel into one with a very tall flange hub.
lack of chainline adjustment isn't strictly true either. If you get a second set of the rag joint plates you can space the sprocket out using ordinary washers.
The problems with this setup come from bad install and maintenance. Always replace the included nuts and bolts with high grade ones and make sure to keep them tight. "grinding the plates" etc isn't something you need to do with an ordinary low flange hub.
+kan't be Good morning! Thank you for the comment! I'll actually be doing a new video with my new builds very soon (November 2016) regarding a comparison of install, strength and long term benefits of a hub mounted adapter and avoiding or at least drastically reducing broken spokes under normal use. Feel free to also follow SCC on FB at Facebook.com/sccmn
Dude....I want to see you flex that sprocket. You are full of it if you think you can.
The day I spend money for builds similar to the ones at the 7:00-ish mark, I'd rather buy a decent, used but well maintained motorcycle. A stock motorcycle would truly be a "professional build" and with insurance, speed that matches other road vehicles and proper signal lights, it would be much safer than any modified bicycle could be.
I’ve never seen you actually try out a 100 dollar two stroke
I’ve had my 80 cc two stroke on a huffy for like 3 to 4 months and basically drove to work everyday had no issues other than tightening bolts over time I have 120 bucks into my bike I would recommend 10 out of 10 but to each there own
Thanks for warning us, lad! 👍
Think I'd rather work with the "disaster" builder "know it all" over this know it all.
Sinister, this really makes you look bad.
i think those are some really good, well thought out points, but I feel like most people who are buying cheap Chinese two-stroke kits are not buying them to be the best, they are buying them to have a fun time without spending too much money.
Its great that you probably have a lot of money to go spending on really nice, hand-built engine kits, but for probably a lot of people, they don't have that kind of money to go spending on professional motorbike kits.
Most folks seem to want something for nothing - at least that is what I am seeing from responses here about 2 strokes and cheapness.... They do not care about longevity nor about pollution Just cheap - and max fun. So be it.
2 strokes require daily attention. every single ride you need to do a bolt check.
the sprocket is the weak point. i built one and drove over 400 miles. sold it.
and the kid who bought totally destroyed it. i showed him exactly what to check for
but he ignored my suggestions.
i installed fat tires on my next version and this bike handled better.
absorbed more road shock. also used thread lock. definitely best choice i ever made.
for those who are thinking about getting into motorized bike....don't listen to this dude. might as well better off buy you a scooter and save your precious time and your hard earn money.
Everything in this video is extremely controversial
I spent about $600.00 on a new Walmart Beach cruiser and fitted my 49cc Grubbee 2 stroke engine kit to it. Had to add a spring loaded chain tensioner and better quality chain, but she's got over 1500 miles on her and going strong after 10 years:)-John in Texas
I don't disagree that you shouldn't be cheap especially with the speeds these bikes go up to but some these parts you mentioned are just not in the budget for most people. I did a solid bulletproof 2 stroke build from scratch doing all the cutting and welding to the frame and fork myself and still spent $1200. That was also getting extreme discounts off parts from a friend that owns a bike shop. You and I might have the means as hobbyist but the "funnest" part is the indestructible build that didn't destroy your budget. You have to remember these are just bicycles at the end of the day and if your local legislators allow them they usually have strict laws to follow.
These were mad for fun if people wanted to spend a lot of money we would just buy a moped or dirt bike or something
One thought guys. I work in the medical field. If your cheap bike breaks up at 20 to 30mph you are going to get hurt. For every 10mph you are traveling, it like falling 1 story high. Example: If you hit a tree at 20 mph its like falling off a 2 story house on to the ground. Your hospital bill could be 1000.00 to 50,000 dollars. It is very logical to have a well made bike. I have seen people pay out 20,000.00 from falling off a horse. I get it a 1000.00 is a lot if money. In the long run its the safest way to go and have something that will last you a long time. Its good to have safety conscious people and people that take great pride in their work. Just my 2 cents on the matter. Ride safely.
Very interesting and cool comment! Thank you for watching and your comment!
I have 2 2 stroke bikes one of which still has the original cross-hatching after 3500 miles. 40:1 is the ideal mixture for motorised bike 2 stroke engines. I have ridden a 4 stroke bike before and to be very honest, i didnt really like it. They have good low end grunt but after about half throttle they bog down. I am jealous of their fuel econemy however
only problem ive ever had with mine was the chain tension pulley, which i fixed by using a rubber sleeve to stop it from migrating down the lower rail.
The spoke clamping type drive sprocket only has one disadvantage in that it can be misaligned, either axially or concentrically.(or both) Either are not good as the speeds increase as the chain can jump off or you'll get an annoying vibration as the wheel turns. However, it does not put extra stresses on the spokes as you suggest. I agree the hub clamping drive sprocket is the better option but it transmits the driving force along the entire length of the wheel's spokes. The closer to the rim the drive force is applied, the less stress there is on the spokes. So in essence, the hub clamping drive sprocket applies the driving force at the same place it would be applied if one were pedaling. The problem is that depending on the motor and the final drive ratio, the motor can end up applying several times the amount of torque that a pedaling human would.
Also, yes the Honda clone horizontal engines are more powerful than the little two-stroke kit motors but there is no commercially available way of adapting one to a bicycle without much fabrication work. As I repair these from time to time I also know they weight more than double what a cheap bicycle motor kit weighs. I'm not advocating for the cheap kits, just correcting the falsehood about them being almost as light and easy to adapt to a bicycle. There is a company I know of who tried to make a bicycle kit that uses a Honda clone engine but their product has been hard to get and also proven to be on the "cheap" side. Check them out, they are called Motoped. Again I'm not advocating for them in fact I would warn you to stay away. They are worth a look only to see what is required to adapt a Honda clone engine to a bicycle type vehicle.
Two stroke gives twice the power as a four stroke and it's why 125 cc 2stroke competes with 250 cc four stroke in mx. Two stroke accelerate twice as fast as four stroke and it's why it's only 2strokes in fmx. Four stroke is more durable than two stroke and easier to control the acceleration and that's why all trial bikes has four stroke (except the smallest ones for kids) anyway to get full power out of an two stroke engine you need a exhaust with an expansion chamber or you will loose at least a third of the power and make a lot more exhaust
I build bikes to get people into them, I don't charge a profit, parts cost only.
Very informative and helpful...
One question: At 2:15, when did it happen and how?
I love my noisy smelly two-stroke!
Your advocating building a quality bike with good parts. I get it. Disagree on your take on 2 strokes. The 2 stroke kits can be reliable if the crappy parts are replaced. 2 strokes can be had that have been improved by sellers. 4 strokes are heavy and can fail if the oil level is not maintained. Not to mention they are bigger.
There are chain drive kits that use Tanaka 2 strokes, which are CARB tier 2 compliant. Tanaka is a high quality 2 stroke made in Japan and will outperform a 4 stroke of similar displacement. They are noisy which is a definite draw back. Both motors have their pros and cons.
I think I disagreed with almost everything in this video, but to each his or her own I guess.
Missing the point of these bikes. In Australia, many people (my age/teens) love them, kmart bikes and cheap kits are just meant for having fun. Its not meant to be long term ride about.
You take the fun out of this hobby. Bring your nose out of the clouds.
Used, but like new, Timberlin bicycle from 1995 ($50) and ebay China special 2 stroke 80cc / 66cc bicycle engine kit ($97) and now 4 months in with 700 miles. No failures other than 2 flat tires. I expect long life from my engine but I do not beat on it. Cruising at 20-24mph is the norm for me and I use it to commute to work.
Proof, you get what you pay for ! Thats why i scratch built my own using my childhood minibike for parts.
I brought a rear hub motor for a 15+ year old bike brought at Target. Steel frame and I've never had a problem with it. Even I'm surprised this bike has held up this long.
Shit, i can buy a who engine kit for $98 with free shipping lol
*8:12** "For speed, reliability, torque performance, I put this up against any 2stroke for a MB. BUT I CANT wait to test it out next spring to see its performance" WTF!? 🤦♂️*
I have a huffy Cranbrook and 96 dollar motor. I hit 40 + mph. had it for a year and 1/2 and it's still kicking strong.
I don't know. I've got many, many miles and a good many years of riding on a cheap $100 49cc motor kit with stock parts. It comes down to doing a proper assembly and set up. MOST problems that people have with these things is because they lack the skill to properly build a motorized bike.
For under $200 I can have a nice home built motorized bike that will be a lot of fun and last 4 or 5 years, maybe more. For a $1,000 I wouldn't spend on a bike, instead I would use that to upgrade the headlights on my Jaguar or repaint my Triumph motorcycle. There is a point where you can really spend more money on something than it will ever be worth.
these aren’t meant to be professional motorcycles. I look at them as a fun project, maybe for teenagers, or an cheaper alternative to a mini bike. Or, some people use them as transportation, which can be done.. for the prices you are going to, you could buy a moped, or even a salvage motorcycle .
nothing wrong with the 2 stroke engines
i agree with your views on proper builds how ever i cant agree with you on the castration of '2' strokes, i can't imagine a "4" stroke weed eater, two stroke isn't going away by a long shot.
8:16 lol go check zedamotorsports on here 16.5hp frank 2-stroke these little bike motors are monsters now bud.
So a $100 kit doesn't last. Just get another $100 kit.
Hey, I have a $99 kit for you. Send the money and I will send the kit - no guarantees on longevity .....
where would i get the part u talked about.i am sick of buying $200 in spokes for my bike. And the boost bottle whats do you u think about them? I heard they work and they do not. if u could can u do a reviwe on it so i know what i am gettng in to?
