Are 4-Stroke Bike Kits better than 2-Stroke Kits? Let's find out!

- เผยแพร่เมื่อ 28 ต.ค. 2018
- In a previous video ( • Are 2-Stroke Bicycle E... ), I built and tested a 2-stroke bike engine kit. For $120, it turned out to be a great kit! It does require a little bit of upkeep and maintenance. In this video, I put together a 4-stroke bike engine kit and then compare it to the 2-stroke bike engine kit. We test top speed, ease of use, noise, amount of exhaust smoke, and several other things. I purchased the kit from Amazon for $189. I don't normally provide links to the products I test, since I'm not an Amazon partner and my goal isn't to sell products. These kits are also available on many other websites. So, recommend shopping around for a better price.

Thanks!!
How muchdo they cost?
Thomas Bostick 120 for the 2 stroke and 150 to 170 for the 4 stroke. The four stoke is worth it It is much more reliable. I have used it to ride to work after I sold my car.
Project Farm can you try to run the 4 stroke bike on vapors?
I’m 13, and my dad is a mechanic, I just kinda wanted to show him that I was interested in working on engines because I ride with him, but don’t know how to fix anything, that 2 stroke kit is coming for me in a couple days.
Fantastic! Glad to hear you are interested in mechanics. Learn all you can.
If you want to know about being a mechanic I would recommend watching chrisfix's videos, he's great at repairing cars.
So how did that kit worked out for you ??
@@eugenecrabs3954 ha thanks
@@eugenecrabs3954 bro that reply could have been 1 sentence, no one asked for a list of mowers
He has convinced me to buy both a two-stroke and a four stroke this man deserves way more than he has
Agree. I have no intention of buying one of these kits (illegal where I live) but I like watching his videos.
..not ILLEGAL anywhere ,,bcz NO VICTIM means No Crime government means MIND CONTROL btw so Stop VOTING and Right ✅ to Travel No License No insurance etc FREEDOM OF MOVEMENT must be allowed and
The 2-stroke and the 4-stroke videos were both excellent, and presented with your customary precision, confidence, and gusto. Looking forward to your next video.
Thanks so much! Thanks for sharing.
Iyot
But the 2stroke is the "Smell" of my youth. You're new to me, I like the detail you give that so many others don't, so I subscribe.
I love that 2-stroke smell, we all ran Castrol 2-stroke oil in our dirt bikes growing up, it's a heavenly smell.
Just run a 2 stroke mix in your 4 stroke engine and it will produce the same effect!
@@applepoop10 I tried that on my 110cc moped. It didn't work. What could be wrong? 🤔
@@applepoop10 yep intentionally glaze your bores make your 4 stroke speed into that of a granny crawling, brilliant
Same here, I run Castrol 927 in my KX500 and my sons KDX200
It’s a very rare thing for such a big YT channel to read and reply to most comments, I’d like to say thank you for taking the time and trouble to do so.
Thank you very much! I really enjoy the interaction. It's what makes TH-cam so much better than TV. Thanks again.
Not only that, PF knows what he's doing with these kits. I'm in a nanny-state of a country (Australia) where these things are illegal, but I like to ride a bicycle, so I've watched a few of these conversion kit videos. This one and the two-stroke one, despite being brief and not 'step-by-step' are still the most thorough and well thought out examples.
@@MattExzy as someone who lives in south australia (pussy state) even the 200w compliant 2 stroke kits are illegal, yet the cops dont pull me over when i whizz past them on my 2500w electric bike at 60kph (or when i out accelerate them at the lights)
👍🏼👍🏼👍🏼
Id like to take the time to say thank you for thanking him.........
If every DIY video on TH-cam was this detailed (for beginners and intermediate hobbyists) I would never have to do any research lol. Thanks again, Project Farm!
Thank you very much!
Check out ChrisFix
I WONDER IF EITHER OF THESE BIKES COULD BE USED BY A 326 LB. MAN ? AND ALSO, THIS MAN WOULD BE GOING UP HILLS SOMETIME?
Lifelong biker here. Loved watching both these vids, shame these engines are illegal for road use in the UK. Top tip for the handlebar grips; when fitting new ones, use hairspray!! The solvent evaporates after half hour, and the gentle adhesive in it will keep the grips on there for life!!
Thanks for the feedback.
Or use ODI bolt-on handlebar grips. I started using those when they first came out for mountain bikes decades ago, and I will never go back to slide-on/cut-off handlebar grips. They're such a pain when you need to service the brake levers or shifters.
You all ought to change that. Storm Windsor Castle and Parliament and have your revolution! Liberty!!!
..Right ✅ to Travel No License No insurance etc FREEDOM OF MOVEMENT must be allowed and Canada and USA and Australia 🇦🇺 are Corporations of Rome btw and government means MIND CONTROL so Stop VOTING and
Not for life, especially in the rain or off roading/torquing on the grips often. Ive got a can of aquanet in my bike tool kit.
I simply love the two stroke oil smell. But the centrifugal clutch is a game changer for the 4 stroke
Especially if you race oil!! Ha ha.
That shit causes severe neurological diseases.
“Don’t use gorilla tape, I want to get this off...”. That is the most accurate description of gorilla tape I’ve heard. That tape is like epoxy. I’ve used to to install a license plate temporarily, and when I wanted to install it with screws, I decided just to keep the gorilla tape it was so clearly adhered to the plastic bumper. It was like that for well over a year. Great video
Thanks!
You need to heat Gorilla tape with a heat gun or hair dryer to remove it.
I ised it for some quick and dirty bidy work on a black car. It didn't look too bad! And the plastic pieces I taped stayed together until sombody bought the car from me. (I showed them the repair).
Man if you think Gorilla Tape is good, buy yourself a roll of T-REX Tape. Gorilla tape is epoxy, T-REX tape is the tape version of welding. The madlad @ProjectFarm pulled a small tractor with one loop of the stuff.
Really? I must be doing something wrong because I've been pretty unimpressed with gorilla tape
Such a great idea, let's call it a motorbike!
Thank you very much! With warm weather finally arriving, I've been riding it 3-4 times each week. Still running great
*moped* MOtorized PEDal bike
How fast does it go?
@@shakoor3218 37 mph
Then you would have to have a licence.
I just wanted to say that I had one of the 2 stroke kits and I used this as my only transportation for about a year ( then it got stolen) and there is most definitely a lot of maintenance involved with the 2 stroke and quite a bit of a learning curve with doing that. The most important thing I found was making sure the chain tensioner was properly aligned and tightened. I had a chain break and that was no fun at all. Also having good tires and thick tubes is a must. Lastly I would never recommend buying one of these kits for a young child to ride, the bike is fun to ride and all but just not engineered for those kinds of speeds. I'm a grown man and it took all of my attention not to get killed on mine when riding around in Las Vegas, probably better off that it got stolen because it was just a matter of time.
Thanks for sharing!
My 2 stroke 125 needs like no maintenance compared to a 4 stroke. I dont know what your talking about .you must not have a good engine or sounds like your talking about maintenance of the bike more than the engine
@@theonewhoknows2 Yeah usually a 2-stroke only need the oil mixed in and a good carb tune and away it goes. The 4-stroke especially cheaper ones will have to always be valve adjusted in order to maintain good efficiency and reliability. Plus it's more moving parts that wear out eventually, the 2-stroke is the king of simplicity.
@@Tomazack yea exactly, my cr125 has only had a couple problems like a clogged jet , besides that it always runs and idles no problem. It likes the crappy autolite spark plugs or ngk as once i had a iridium spark plug and put it in and it burnt out the first time i started it with it.Most reliable engine i have ever come across
I agree with you about the safety concerns. I was thinking about the fun and efficiency, etc. but after my own experience riding human powered bikes on wet downhill roads, I felt myself struggling to keep control. After seven miles of getting soaked by the rain, then realizing that my front brakes had come loose, your message reminded me of the potential dangers of a powered bike. Unlike motorcycles, which can also be deadly, bikes haven't enough weight to aid in control during high winds and bad weather. Too risky for me.
Thanks for another great video. I watched both the 2 and 4 stroke videos and enjoyed them. Riding a bike at 37 mph is pretty brave. This has me thinking about building one for myself.
You are welcome! Thanks for sharing.
Another 4 stroke advantage: no mixing fuel and oil
Great point!
cool name dude im doing a build that might turn into a giveaway check it out
That's one of the reasons I hadn't built a gas-bike. Just from that alone.
Yeah, that's really hard work...
But that is the advantage. Gas n go. One less part to maintain.
Next diesel bike build😂
Nice! It'll definitely need a big coffee can exhaust tip too!
@@ProjectFarm better yet lets do a biodiesel bike
boer brabant then after that a 2 stroke diesel bike

“twin turbo 6.5 litre V8 bike kit”
Nice!
Nah fam v8 loves superchargers more xd
that_cat ahahahah
squeeze a Bugatti quad-turbo W-16 mill under the seat and go set some land speed records!
Mr. Long Legs ls swapped bike 😂
Build a forced air intake for the 4 stroke (Turbo or Super). Completely ridiculous for such a small engine but I mean it's an engine on a bicycle already so why not try going a little silly....
Great video idea!
DO IT
DO IT
Just go with a nitrous oxide set up. There are kits out there already that could be used.
Fun idea, but from my research, very difficult. Most single cylinders can't provide a steady enough exhaust stream for a turbo, need a lot of RPM. Takes a lot of knowledge with carb sizing, placement, tuning and ignition timing.
I love your show, I've been with the Home Depot for almost 22 years now. I recommend your show whenever someone has questions on products you've tested. They make a 12v turbo/super charger for around $100. It might be fun to hook that up to your 4 stroke bike motor to see what it does.
Thanks! Thanks for the suggestion.
It would do nothing. Its an electric fan and nothing else
Nighthawk in light did a show where he built a wood gasifier for fuel. I've been using 2 stroke kits for a few years. I think I'm gonna build with the 4 stroke kit next.
hmmmm
Really cool videos on these bikes!! Great and well done and documented projects. Definitely makes me want to do one. 👍
Thanks!
The 4 stroke Engine performance can be increased very easily with just a bit of carburetor and exhaust modifications. I opened up the fuel & air circuits and added a better breathing air filter . Modified the exhaust pipe as well. It gained 8 mph @ WOT and has much better acceleration and power throughout the rpm range. I would estimate it gained at least a single HP . But probably not much more than that. It definitely woke up because a 25% increase in Top speed is significant irregardless of engine displacement. It had a previous Top Speed of 36 MPH and now consistantly runs 44-45 mph
Impressive!
@@ProjectFarm might be if it stays together . I may have sped up not only the bicycle but the engines day with death. And maybe Ive increased its life span by making it more efficient. One will never know. But the intake charge running richer has made it run a bit cooler and the speed increase helps with the cooling as well. So that definitely adds to efficiency and efficiency adds to higher average power production throughout the RPM range . Time will tell. But It is pretty impressive to me that it will now take off on engine only power carring someone my size ( 6' 2" and 221 lbs . Its no dragster but does indeed pull off with a increasing speed and RPMs without bog or hesitation . It definitely wouldnt originally. Im sure its pretty hard on it to do so . But it does do it.
Holy moly...anything over 40mph on a bike is dangerous. My top speed down a local mountain road is about 47mph on a mtn bike and that was nuts... Honestly.i'd stick right around 30mph if you don't want to die... and keep the reserve speed for when a band of backwood bandits start chasing you.
@@mrinternet5562 I drag race a Top Fuel Harley Davidson and have been drag racing bikes for 26 years. I think I will be ok
@@GorillaCookies Except you're talking about motorcycles. Bicycles are not meant for all that weight, forces and vibrations at those speeds. He is very smart for sticking it in the 30mph and if that.
You compare the two only shows that you're most in danger, because ignorance is a killer.
lying down and watch this with a cup of hot coffee, wondering this will be my next project during this covid19 lockdown..
Thanks for watching!
Same 😂
I did one, it’s honestly a great way to pass the time. Putting it together is one thing, tuning and modding it once you find out the potential they have is another. Lotta fun you can have
Just bought a bike on craigslist for $50 and this kit on amazon, thanks quarantine gonna have a fun weekend
Same!!
Thank you very much for this, I was back and forth on getting one of these because my mechanical knowledge is..well..not good, in fact one of the reasons I want one is to learn more by installing and maintaining it. This will be a huge help and prevent me from being at the mercy of my motorhead friends for everything.
You are welcome! Thanks for sharing.
aaah this guy is such a joy to listen to. Never trying to be funny, none of that 'personality' and 'brand' building lots of other YT channels engage in. This man uses verbal communication exclusively to convey information and I love it.
Thanks!
Had the same trouble with the filter box not fitting in the frame for mine. The kit I used came with much better instructions, but I would have traded those for your all metal clutch. Mine has a plastic outer cover that was cracked on arrival. I've never seen cheaper cardboard than the box the kit arrived in.
Thank you
No, thank you
Ooh it's NightHawkinLight, I have watched him for years
I was like... "oh NightHawkinLight... he hasn't posted in forever, lemme see what's up.." I was unsubscribed.. I didn't do that, and that's not the first time that has happened, it happened with VSauce3 recently as well....
Why is TH-cam unsubbing me from random channels?!
Has anyone else had this issue?
If the airbox don't fit, build a small ram-air intake using a length of vacuum hose and reposition the air box/ filter. That should take care of your problem.
I’m having flashback to my friends and building out our mini bikes. “Master link keeper” started to give me flashbacks.
Love your videos!!! Always fantastic
That is awesome!
Great video. What' funny is I just watched your 2-stroke build yesterday so it was still fresh on my mind. Another example that you forgot, unless I missed it is no mixing of oil on the 4-stoke. That and the fact it's much quieter makes which one an easy decision for me. Gracias!
Mixing 2-stroke fuel is a problem? Really? We have become pampered children in adult bodies.
Hi, PF. I appreciated the way you were able to modify the kit to fit it into your bike. Way to go. Thanks for sharing! Stay Healthy!

You are welcome!
Your channel never stops amazing me . Almost anything I’m curious about, You got a good video on.
Ya need a raise . This channel is fantastic!!
Thanks and you are welcome!
Nice to finally find a video for the 4 stoke that is in English and he explains it
You forgot to mention that you have to premix oil and gas in the 2 stroke, where in the 4 stroke you don't. A minor detail, but an inconvenience non-the-less. Great video.
Great point! I should have mentioned that! Thank you
it is not minor if you forget to mix it :D
in 4 stroke you have to change oil regularly so where is advantage? 2 stroke is so easy(speakin about good engines no chnese cheap toys) no manifold... in compare of weight and horse power will always win 2stroke...and smoke? If you use proper spark plug & set good ignition its no smoke...
great video man! so much work is put into your stuff man, much appreciated!
Thanks!
Great videos! I agree with you concerning the 2 stroke engines. My Grubbee 49cc 2 stroke only has a top safe speed of around 22mph, but I've put over 1000 miles on it over the last 2 years. Am impressed with it's durability-John in Texas
Thanks!
For those metric guys like me top speed is 56 km/h
Thank you!
@@ProjectFarm 1.2 kw aka 1.6 hp ? Need a turbo on that thing :D
Thx mate
56km/hr in non retard units.
Thx
Thank you for another fantastic video! I have learned so much from your videos, your intelligent, thoughtful and thorough testing and insight has influenced my decisions on many products over the years. Please keep up the great work and we can all learn together!
Thank you for the feedback!!
Another excellent comparison. Very informative and very well done. Thank you!
You are welcome!
Some of my favorite videos are the ones where you make something run from nothing, and then test that! Makes me do a happy dance..
Thanks for the feedback.
I like the 4 stroke because they are quieter in my opinion and riding in the neighborhood is less obnoxious
Thank you
Plus you don't have to pre-mix the gasoline..just change the oil on a regular basis (I don't think these little motors have filters and just like a Honda Rebel 250, gotta change the oil often to get rid of any gunk that might build up)
electric. dead quiet and 5% of the parts!
@@thomasjaszewski64 And 5 times the price.
@@ChefofWar33 Electric has much higher MPGe (around 900 MPGe) ,much less indirect harmful CO2 emissions per distance traveled,you can pedal along bionically with the motor but doesn't have the advantage of easy refilling of fuel and nearly unlimited range as the battery takes hours to charge up.
If you want exercise plus ease of going up hills electric is the way to go. I've gone 46 miles on an electric bike in range.
If you want unlimited range with easy gas refills at a gas station an I.C.E. bike is better.
Also it depends on state laws too.
Many states won't allow I.C.E. bicycles on streets,roads or highways.
In my particular state of Washington I.C.E. bicycles are considered unlawful non licensable motor vehicles.
Considering the amazing MPG's you can get on a 4 cycle I.C.E. bicycle engine perhaps 200 MPG it would make sense to have them made lawful to combat anthropogenic CO2 emissions (Climate Change,Ocean acidification,Sea rise etc.) by having people ride these rather than inefficient heavy motor vehicles (passenger cars) which have a vastly lower MPG rating. Electric bikes serve one purpose and I.C.E. bikes serve usually a different one.
They can compliment each other too.
I think your videos are really cool. I like how you explaine everything. Keep up the great work.
Thanks, will do!
Thanks for your great work! Really enjoy your shows.
About 40 years ago I put a chainsaw engine on an old 20" 5 speed. I use to fly all over the place, not knowing that was irritating people.
I was riding it down near the beach once, and was stopped by a cop that I had a few run-ins with back then.
The asshole was happy he got the chance to give me quite a few tickets that forced me to be unable to get a license till I was 21.
Driving a motorbike without an operators license, no registration, no lights or required safety equipment crap.
I remember standing there in court and instead of the judge saying something nice like " you built that thing yourself" ?
No, instead he said " you seem to do what you damn well please don't you."
Then told me I better be careful how I answer.
I never did get the bike back.
But boy did I have a hate for cops after that.
And that wore off too.
30 years later.
That would have been a very frustrating experience!
I live in Southern Arizona. We can ride a bike legally as long as it is under 50cc, has a mirror, headlight, tail light, and foot pegs if you carry a passenger (pegs pointless on a motorized bicycle). Eye protection is required at all times, helmets by law for anyone under 18 years of age. What make them a "motorcycle" is fixed pegs and you have to license, register, and insure it. You also need a motorcycle endorsement on your license. For the most part, the cops in my hometown leave bike riders alone unless one of us does something stupid like running stop signs, excessive speed or something similar. I've had Pima County Sheriffs follow me but none made a move to light me up.
yeah ive had a similar experience, i got dinged 2 grand worth of fines when i was younger on an engine bike, just part of the game, some cops are dicks, they will end up shot eventually tho karma works itself out
IT IZME_ motor assisted bicycle street legal 48 states in Tennessee only requires valid license and helmet no motorcycle endorsement
.....i have the same story as you, lol!
Thanks for posting this...
I've been wanting to build one myself for some time but was a little intimidated by the complexity of the job, having never done a project like this before...
But, the easy, straight forward way you did it have me the confidence to take the plunge a give it a go.
I think...lol👍😃
You are welcome! Thanks for sharing.
We learn from mistakes, and practice makes perfect.
So how did it go?
Dude. I just found your channel the other day and I'm HOOKED. Keep up the great content my friend 👍
Awesome! Thank you!
this is cool , i had a very small 2 stroke car from Subaru in 1971. 2 clylinder it had a snowmobile engine.I also bought a 1967 Saab 96 with a 3 cyl. 2 stroke, it was an off road monster, both hill climbed. great milage on both.
Thanks! Thanks for sharing.
This was great, I didn't know these engine conversions even existed! Thanks for making the video!
They are a lot of fun! Thank you
Ty for your great videos! After watching your video, I built a 2stroke motor bike for my kids. Although not easy, to get it started, needed to confirm spark with ngk plug, and rebuild carb jet, and clutch. Great content 👌
That is awesome!
With the chain tension, you can put a pin or bolt through the frame to keep it from moving or weld a flat steel on the bottom. Drill a hole to put your bottom bolt through it. Both will keep it in place.
Thanks for the feedback.
Love your videos! Your hard work and honesty is so much appreciated.
Can you do a video on your equipment and editing process so we can learn how to do videos from an expert
Thank you for the video idea!
Put a turbo on the 4stroke bike kit.
Thank you for the video idea!
No problem.
Or go one step further and install a Jackshaft and use the existing rear wheel mountain bike sprockets as a form of gears to get some good speed from your bike.
Or an expansion chamber on the two stroke.
@@daemonwhitebeard6590 Lool imagine the top speed, you'd definitely need to upgrade your brakes
Nice kit! Clean install. :-)
Thank you very much! You've got a GREAT channel. Thanks for all of the videos!
I had never considered a gas powered bike before but that looks like a lot of fun. I think I prefer the four stroke over the two. If I can use a kit like that on the bikes with the large tires I think I would be rolling!
Thanks for sharing.
Well for being a modified bicycle they both did what you'd expect.
My question is how did they turn and stop at speed.
I noticed with my bike build that the tires would depart from contact
with the road maybe a quarter of the time. Making it a challenge to safely maneuver.
My build was on west coast chopper sting ray. I was always going to put a suspension on it front and back, Oh and mine was a mantis tiller motor and worm gear and the shroud bolts were employed as a stressed member in the frame I removed the crank.
Another great video !! U put so much into your videos i always love to watch them
Happy to hear that!
Idk much about mechanics but enjoyed watching this natural genius at work!
Glad you enjoyed it! Thanks for watching.
I put the two-stroke on it on my mountain bike it's a lot of fun and I love it I would like to try the four-stroke one also but any suggestions from you would be great I like your video I like all of your videos you're very intelligent human being I was an aircraft mechanic in the military for 15 years and I always enjoy learning new things thank you
are they a lot of maintenance? cause i’m just trying to build one and not have to work on it all the time
Go with a staton friction drive and a Honda gx50nts3 you will not be disappointed
Watching your all comparison videos over and over again
Very nice content
Thanks!
I have been trying to make up my mind. Thanks this was the exact comparison I needed. I'm going 4 strokes quieter, less smoky (neighbor-friendly)& 4-strokes last longer.
I am a big guy, but speed is not an issue- not pedaling is LOL
I am impressed you are a jack of all trades, each video brings out a new skill. Great job.

Thanks and you are welcome!
Did you ever see way back in the beginning of bikes and in enters making powered bikes and early motor cycles one inventor came up with what I would call a motorbike with the motor built inside of the wheel. It's been probably twenty years ago that I saw the article and pictures and I cannot remember now which wheel that it was actually built into, but it appeared to be quite a piece of engineering and I always wished that I would have loved to see how well something that that would have operated!
You did a very nice comparison of the two pointing out the advantages and disadvantages of each and with your fairly thorough explanation I'm sure you make a lot easier for a person wanting to go this route for some cheap transportation over walking everywhere to make their decision on which to purchase for their needs verses probably just a guess otherwise. I think a lot of people would choose according to cost but after hearing your assessment may choose otherwise. So another fine job by you again!
Thank you very much!
One big advantage that the 4 stroke has over the 2 stroke is that you can literally pull up to a gas station with the 4 stroke fuel up straight to the tank. Where as the 2 stroke you will need a little gas tank of premix with you at all times for long trips etc... Really Enjoyed this video Project Farm!
Thanks!
6:40 An additional safety move would be to drill through the tensioner bracket and into the bike's frame to install a lock bolt to keep the tensioner from rotating into the spokes if a tensioner is needed.
Thanks for sharing.
That is a fantastic hack and one that will allow you to get finished quicker instead of having to break the chain.
In my experience it doesn't move at all. Granted, my frame tubes are not round, they're oval, but yeah
Good idea
Or you can use some rubber and tighten the bolts
Well done & very informative video! Thank you! A lot of fun too! 👍
Thanks so much!
Nearly 40 MPH on a bicycle! That is scary!! Thanks for the video. Always love watching. Your content is fantastic!
Thank you!
going any fast speed on a 2 wheel vehicle seems to appear faster than what you're going, the thing that shook me to the core after taking my motorcyle well over 100mph on a deserted back road was, what if? a car pulled out? or if something else went wrong!? getting thrown from a 2 wheel vehicle is no fun! got dumped off my dirt bike many a time!

This is great. Haven't seen anyone mention this and while I typically prefer 4 stroke, with a bike like this would take the 2 stroke in case you dump the bike or want to put it in the back of a car or truck so you don't have flooding issues. Obviously adding a fuel shutoff would help with this.
Thanks! Thanks for the feedback.
Awesome thanks. This is something my kids and I can do over winter.
You are welcome!
Sometimes the easiest fixes are brilliant at the sane time. I have a tendency to over think things sometimes, that piece of pvc pipe was great thinking i would have probably tried to relocate them and ended up with no brakes at all😂
Great review, was really surprised at how fast they went.
Thank you!
I know this is an older video but I really liked it, I enjoyed how you compared the two and the build for the 4-stroke was very helpful.
Thanks! Glad to hear!
You know you can get a double pull brake lever that pulls both brakes with one lever so you can have brakes on one side and clutch on the other. Worked out great for my 2 stroke kit. 37 is hauling ass on a bicycle! Mine went 28 on our little country road and scared the snot out of me!
My top speed on a road bike is 58mph. Was so fun and also terrifying at the same time. Especially when a mom tried to jump out in the middle of the road bc her kid was riding a quad 💀
One of the best youtube channels, you deserve way more exposure.
Thank you very much!
I agree
Your video helped soo much i am so over wasting energy pedaling to far away places to get what i need! Definitely going with the 4 stroke as it is quiet!
Glad it was helpful!
Would love to see the torque differences between both engines as well.
The speed test, as I could see, was made in a flat road. Would be great to see on a road going up and compare both of them.
Thank you for the video idea!
Awesome video with detailed walkthrough !! good stuff man !
Thanks and you are welcome!
I'm waiting for the V8 bike conversion 😃
lol. That would be impressive!
Seeing how small the 4-stroke is, i think they can do V8 too lol...
Same,but then again the power would warp the cheap aluminum frame
It will pull out the spokes first a guess...
Don't tempt him... There are 125cc custom v8 kits out there - but they're *horribly* expensive. And I'd love to see a coppers face when that buzzed past his patrol car...
Now electric bike kit ?
I got a second hand one only 250watts but its awesome having to hardly pedal at all and whizz by everyone in total silence.
My no1 tip: don't use a cheap old bike, get a nice comfortable touring bike with hydraulic fork and spend a little more on tires, mine are Schwalbe Marathon totally worth it and very comfortable.
Great video idea!
@@ProjectFarm Yeah, adding an electric bike kit and comparing it to the 2 & 4 stroke would be great.
I got Schwalbe Big Ben on my ebike. Smoothest ride ever!
I always wanted to test some Aliexpress/Bafang bike kit, but was always afraid to try!
If you test an electric bike kit, please go with a pedal motor and not those crappy wheel motors
I watched a video a young kid done,, he used I think it was $139 cheap eBay electric bike kit. But he used three 22.2. volt batteries for a drone. For a total of 66.6 volt,,. On a 48 volt Hub motor,, it was powerful and had a extremely long range but mainly it could climb steep hills with no problem,,,. And a electric motor loves the extra current,,. I think the batteries were about$40 a piece,,. ??? Definitely the best bang for the buck power-wise speed-wise torque and super quiet,,,. I'm going to do one and add a two stroke gas motor,,,. That way I can go anywhere and be legal,,,. !!!
I think it was a 500-watt motor,,. From my research anything less is junk,,,. And pedal assist,,. And all those electric bikes are way too expensive,,. And replacing their batteries is to,, one of the biggest cost,,. Build your own I definitely will,,,,
Thanks for the info between the two. 👍
The bike test run reminds me of Harry's Garage videos when he takes his exotic cars for a spin, I also like the fact that it started so easily to.
Thanks for sharing.
Another video that is just so nice to watch! I love you videos.
Thank you!
FYI sprockets just like the one in this video with more rectangular slots for the hardware; you can use carriage bolts because they have a square bottom underneath the dome cap. This allows for you to get a perfectly aligned sprocket every time!
Thanks for the feedback.
I really loved these build videos you use to do more often and you seem to have fun doing them. You should break up the testing videos every once in a blue moon throuw a build you enjoyed up on TH-cam I'm sure people would love it!
Thanks for the suggestion.
Brother, great video. Thanks for taking the time to make the video. I was looking at how to mount my gas tank. I have the same shifter/brake cable set up. The PVC pipe is money 💰! 💰 can't wait to try that hack. Hope to see you make another motorized bicycle 🚲 🏍 video 📹 🙏 one day!
Thanks and you are welcome! Thanks for the suggestion.
Next video, 4 Stroke with shaved heads bigger valve's, new racing carburetor and race fuel with a bigger wheel sprocket. 🙂
Great video idea!
you want him to break his neck popping wheelies out of control lol it needs a smaller rear sprocket not bigger that way you can get more top speed out of the bike even if the engine lugs a bit down low you can augment it with pedaling and then when the engine can take over you will go faster.
@@jessaphillips2846 Yes but it depends on the size of the front sprocket as well.
Really be best if it we setup to change gears. Would be the best of both worlds. 🙂
Cheap electric kit will smoke these stink pots. Yawn. Thanks for the great video!
With the proper stuff you can actually get the power to the right side of the bike and utilize the bike gears to give you good take off and good top end. I did this with a grubee 10g shift kit on a skyhawk gt2 frame. It's a bit costly but it is well worth it. Fyi if you plan on doing it yourself you will have to have more than just a basic set of sockets and screwdrivers. I also recommend the shimano 7 speed cassette mega range 14t-34t. It's a bad ass bike. If anyone wants to know I can post a link to my page with photos of said bike.
i'm probably going to end up with a 2 and 4 stroke and an electric....i don't need them just want to build them! lol
Nice to have all 3!
Of course I'm going to ride them like a rented mule
I’m planning on doing a hybrid with a 212cc and a 1000w front hub, having to run the hub off the engines power and a capacitor to the battery lol
@@AdrianGtz that would be a cool prius bike
That's what I do, too.
I have built a bunch of bikes over the years and first thing I always do is drill a few holes in the end of the exhaust pipe, (more air), the high performance 3 prong spark plug helps, I always change the 44 tooth sprocket to a 28 tooth. I personally like the dual pull brake lever if its a 2 stroke so there aren't extra levers. Oh and my favorite cheap Walmart bike to mount it on is 29" genisis mountain bike because it has disc brakes and a front shock and at high speed the 29inch bike is much more comfortable. I just recently tried the sprocket hub adapter and it is sweet. With those modifications every bike I have built goes over 40. If a tensioner is necessary the spring tensioner is a must
Thanks for sharing.
For a comparison data point, I used to have a Honda NC-50 Express. This was a 2-stroke (oil injection, no mixing required) 49cc single speed motorcycle that looked just like a moped but without pedals ($325 new in 1978). It topped out about 28mph on level ground. Given a hill it would accelerate to about 35 mph and could sustain 32mph thereafter on level ground. It got about 175mpg and went 1,000 miles on a quart of oil, no visible exhaust. Used to find almost enough change laying in the curbs to fuel it (it stopped on a dime when I stopped FOR a dime).
Thanks for sharing.
The 4 stroke is way more quiet. I like it, the 2 stroke makes a whiney sound if it makes sense. The 4 stroke makes a "deeper" sound and its not annoying at all. Nice video!
Thank you!
The two stroke sounds like a chicken chaser, the four stroke sounds much better
Two stroke reminds me exactly of a chainsaw. If you dream of riding a chainsaw it seems like a good choice.
l have never tried the 4 stroke kits but have on the 2 stroke, the build quality on the 2 stroke is real cheap with lots of failures, plus most states limit you to under 50 cc so they are not legal if they wanted to bust your balls, , that 4 stroke kit supprised me on its top speed, one question l was thinking how did they do when pulling a hill?, thanks again for making great videos, you are at the top for me,
Hi Mustie1! Great point on the 2 stroke kits. This 4 stoke kit seems to have a very good engine on it, but I'm not sure how the clutch will hold up. The 2 stroke did much better on the hills, but the 4 stroke would do a terrific job with a larger back sprocket. I really enjoy your videos and congratulations on 200K subscribers!
Hi, Darren, I watch all your videos too.
Hi mustie1 I’m a big fan
2 strokes are only if you are a BO$$!!
ez to fix though, just gotta give it that, lots of cheap parts to upgrade them with too!
I didn’t expect all the great instructions thanks
You are welcome!
Great video! I would have liked to see you filling the crankcase and what type of oil is recommended. Very well done!
Thanks and you are welcome! Thanks for the constructive feedback.
