In this video we will examine the performance of a 2 stroke and 4 stroke 50cc motorized bike. This side by side presents the similarities and differences on the road and in real life elements. I tried to keep everything as unadulterated as possible so that YOU can choose which engine is the best for YOU!
I tried to keep FLUFF out of the video so that we can focus on the juxtaposition, but some things had to be mentioned for a full, rounded explanation.
Once again...my riding conditions are different than yours! If your bike goes faster--SWEET! This is stock and out of the box to be as authentic as possible.
I hope you enjoy the video... Thanks for watching... And PLEASE LIKE AND SUBSCRIBE!!! - ยานยนต์และพาหนะ

I have built many 2 stroke and currently on my first 4 stoke build. 2 strokes and definitely budget friendly and tons of upgrades, but more maintenance and 2 strokes are LOUD. My 4stroke goes just as fast stock (35) and its quiet and smooth! My opinion. If you are looking to have fun buy a 2stroke but to get to work, get the 4stroke
Same here.
Same...I'm a senior with many years of small cycle experience, and now I live in a better-grade place where I don't want neighbors upset when I go out or come in really late or early...:)) Upgrade a 4-stroke just 5-7 mph is enough and still quiet.
I lost my license for a year and have decided to commute by bike to work. Problem is I'm 350 lbs and my area has a lot of hills. I've been doing alright and been losing a bit of weight but I defintely would like something to help me on these hills so I can go more places. Would the 4-stroke be better for me then?
@@tcmedialab hey i used to weigh close to that and ran a 2 stroke to work for a year. I think its down to maintenance preferences. If you can afford, a fat tire bike with a 44t or larger might make those hills smoother in my opinion.
"35" means mph or km/h?
Also with the 2 stroke, they love to be revved and I noticed you gave it little revs and let the clutch out way too fast when doing off the line. So learning how to better use a clutch would probably help the performance
OUCH!!😬
Instablaster.
Classic 2 Stroke Guy excuses. "it wasn't ridden right, it was to lean, it needed a rebiuld"
@@trxtech3010*rebuild
Thanks for this! I am partial to 4 stroke, mainly because I like the sound and no mixing fuel. Maintenance is also a factor. The cost is worth it to me. Again, thank you!
If you have a smaller bike, go for the 2 stroke though. It will fit better
I love my 4 so far just make sure you get the good motor mount the one that came in the kit was crap and still had to do a bunch of grinding on the mount to get every bit I could to fit the bigger motor but well worth it.Plan on doing another kinda fun for a 64 old retired.
4 strokes are convenient and easy to ride but 2 strokes in my opinion are more fun because of the Manuel clutch, and when tuned right the are really fast
They are also easier to install and work onto bikes
Plus way more modifications
Yeah but I don't want to die going full bored out. I have a temperamental 2 cycle motorized bike. CLUTCH HUH? One time I forgot that the clutch was not the brake. Crash! Bike is okay! I have some pain. Ha! Ha! Bike ran the other day. No carburetor cover or air filter. Bought as is, running!
@@kennithumperovitch1312 all motorcycles use the left handle as the clutch
@@shancyroesner9212 I know that now! I have a motorized bicycle thought that would be different.
I'm watching this video because I'm getting my first 2 stroke soon I can't wait for it to arrive.
I got mine almost a year ago. Put it on a lowrider micargi.
Someone wanted it BAD. Offered me $1500.
But it was my first build and I didnt want to part with it.. She's my little green lady lol
People love it
Did u end up building it?
I am getting mine back, modifying it and throwing it on a new bike.
Same plus $50 in parts. expansion chamber and muffler, should make it about as loud as a normal sedan
One option that's often overlooked is the BT80 (bullet train), which is an electric start 70CC 2 stroke with a 12V battery, oil bath clutch, and a charging system. Not only are they a bit more powerful than the 49cc motors, but have a full electrical system to wire up a headlight, turn signals, brake light, electronic speedometer/tach, etc. Lots and lots of possibilities there.
Hpw expensive is it
That brings in the issue of it being over 50cc and having to get it registered in many areas,
(But most dont bother to check mine is 100cc with "50cc" stamped onto it 😂)
I was digging through all my bike stuff and found an old Indian frame I had. Put a 4 stroke on it. Fabbed up my own motor mounts. Only issue I had was the exhaust interfered with the frame. Easily solved by heating with the torch and bending it how I needed it. Started out with the stock 44 tooth sprocket, and the bike didn’t really have any legs. Changed to a 40t, better, but not quite. I’ve been running a 36 tooth and it does great. I really don’t want to be going over 35 on an over 100 year old frame. Matter of fact, I couldn’t keep those old rims tuned, so I put a set of worksman 11 guage spokes wheels on it. It’s great fun and I ride it to work every day, about 15 miles round trip.
Now the weak links in both of these kits…..
The rag joint. They’re ‘ok’ if you set them up right. Spend the money and get a hub adapter.
The chain tensioners are garbage and dangerous. I’ve seen and heard of too many of them coming loose and ending up in the spokes. For the 2 strokes, they make a spring loaded one that fits on the gearbox. No such option for the 4 stroke.
I found my best option was welding a Chevy small block alternator bracket between the seat stay and chain stay. Strong, cheap and looks better.
I’ll be looking into a torque converter or a sun clutch soon because the centrifugal clutches are the weak link on the 4 strokes.
Great video. Just remember everybody, ride like you’re invisible, because you are.
Thanks, I miss your bike builds. I appreciate everything you upload tho.
2 strokes are more fun, fast, and loud. 4 strokes are a bit slower but generally easier. Depends on what you want.

Always been a 2 stroke guy myself. I have some vintage dirt bikes. I have a Honda CR500 and a CR480R. Their powerbands are a RUSH!
@@scottcupp8129 yup like a slingshot had a h2 kaw like that
79cc 4 stroke phatmoto guy here. i love my 4 stroke for commuting. a 2 stroke to gear faster n rip on the weekends be fun too.🍻
Excellent video, your visuals explained everything without trying to talk over the engine noise .. Well done!
If I ever had one of these, personally I'd prefer the 4 stroke. It might not be quite as quick, but it's easier to maintain, quieter (I'd rather not have a noise complaint) and generally more reliable
This was very well done, very informative, thanks, will look for the next.
Excellent comparison for the 2 vs 4 stroke engines. They both have their advantages and disadvantages.
I have been building Motorized Bikes ( AutoCycles) for six and half years and have 5 in my garage and working on the sixth one now (to be completed , tomorrow, Sunday 26th)., with a further two in my lockup.
They range from the two old ones, Humber Cycles, to 3x 66cc 2 Strokes, one 43cc Weedeater ( weedwacker in your part of the world) in a folding commuter cycle. Two 4 strokes, one 39cc and the other 49cc same as your engine. The 39cc is side mounted on the left side at axle height.
I thought this was a lotorweek show for a minute!! Well done!
Probably the best comparison of the 2 and 4 stroke engines...helped me a lot!!!
What a fantastic video 👏🏼 I’ve been building the 2 strokes for 10 years now. Now considering the 4 stroke, I’m just curious 🧐 this was a great overall view of exactly what i needed to know. Thank you
Thank you for watching and being a part of the community.
Great video! Keep up the great content.
Awesome comparison vid!! Thx
I've noticed some of the 4 stroke kits try to sneak in the same price but leave out either the motor mount, the wide crank set or I've also seen BOtH left out and still like almost $300! So, be sure to pay close attention to what's included in the kits!
This is the best video comparison anyone has ever made.
I am truly grateful for this comment. Thank you very much!
I've just fitted the 4 stroke, although I have some issues to overcome. The air filter has to be changed and I'm going to have to bend the exhaust more or cut off the bracket and re weld it so I can mount the exhaust. The 2 stroke is notably smaller.
I just love your video and I like how you're not biased you don't voice your opinion you just show the product what it is how it performs straight-up just too products and not your opinion I love that your video is simple I like how you plainly stated that there is different variations due to user it really help me decide on what versus what thank you very much please make more videos some videos i.cringe just to watch their videos either they can't narrate properly or something wrong with their voice or their language of their English watching your video was quite Pleasant
good video very well put together
Great video Mark
In my experience the two stroke is louder, has more exhaust and there is more power at higher RPM. 49cc and under is street legal in some places.
Wow nice informative video great work
Im sold on the 4 stroke .Quieter ,runs just as fast , no fuel mix why not hey .
Great comparison mate , appreciate all the effort and edits great work
Wow great comparison video
Video is educated to me. Awesome and Thanks
Love ur video. No bs, right to the point
Nice video, I've dealt with both and even the 79cc predator. I eventually just went to the predator 212cc. Completely different and it changed the whole bike.
I wanna make an oil drum cart with a 212.
I have a predator 212 on a gokart, and you put it on a bike?💀
A 212 on a BIKE???!💀💀💀💀 that will probably kill you haha
Where you ride it to commute or fun?
Great video!
There's much more upgrades you can do with both engines, especially the 4 stroke to make it better. Other than simple upgrades such as the carb or exhaust, if you put the work into it you can do the insides of the engine as well and make it preform much better. That applies for both engines. Also the sprockets can be upgraded to a adapter clamp and can be adjusted to make sizes.
Awesome job
nice, this was one best videos of 2/4-stroke motors that i have seen. 4stroke seems to be better chose even if it cost more.
It’s not, valves need adjustment as soon as you run it for 5 hours, centrifugal clutch wears out crazy fast, gears in transmission often grind after wear, gear shaft splines shims off after a while, both aren’t the best but 2 stroke has a mechanical clutch which means you control it better. I’ve owned both bikes.
@@Farmtractor i only find valves need sorted that quickly if you keep the engine high rpm for any extended period of time, which for these bikes is a problem due to a single gear, you can lesson valve problem through gearing but will loose most the torque just to get a suitable cruising rpm on the 4-stroke, i've put 100+ hours on these engines and not needed the valve clearances sorted. I dont find the clutches to bad either, you would spend more on 2-stroke oil than you would clutches for the life of the engine, just the hassle of having to swap them out every couple of months. But weight has a major factor in this, if your a bigger person expect to do triple the maintenance on these parts, same for weight of bike, tires, and terrain you use it on.
trust me 2 stroke is the way to go in these small bicycle engines, two stroke has way more performance potential on the same cylinder size compared to fourstroke
4 stroke overall are just better. They have a bit less torque so they suffer a bit on inclines, but more overall power allowing faster flat speed.
Also the fact you don't have to mix oil in with your fuel means it is cheaper to run.
It has a less grating sound as well, I have always found 2-stroke motors to be extremely annoying.
@@Farmtractor your explanation helps my decision much more. What brand kit should I get
Well done video! Thanks for posting.
LA Hover : Thank you for being a part of the community 👍
@@SouthernCustomCC hello
6:19 26kg 2 stroke, 29kg 4 stroke
So what? That's a true statistic, but it makes very little difference to an average rider who is having a good time on either bike.
@@dehoedisc7247 He was just converting it from pounds to kilograms. Calm down.
Obrigado!
Informative Video
My first build was a 2 stroke I got off of ebay. Cheaper to initially set up, but high maintenance with low quality parts. Ultimately it didn't last. For my second build I went with the 4 stroke. I will never run a 2 stroke again. I cannot believe the difference. Every single thing is better about 4 stroke.
Great video! Simple solution, get both!
How did you get the brakes to work with the sprocket? I tried on the Hyper and the brakes wouldn't work too well and when you pressed harder they kicked the pedals ..
I´d take the 2 stroke for sure!
So many options to make more power...
Got to love them hyper bicycles I think that's what kind it is LOL
I live in a pretty hilly are, and I would like to know if the 4 stroke torque is comparably better for up hill driving compared to 2 stroke.
I had a 4 stroke, sadly it was stollen, and aside from the transmission being messed up from the only issue I had with it was gas getting into my oil pan.
Probably had a improper float height in the carb
4 strokes looks cool
I like this idea better then my moped. 😊💪👊
Thank you.
the only REAL performance mod I've found on the 4 stroke is replacing the stock carb with the 2-stroke NT carb. Picked up a few MPH and better midrange power. The stock box muffler (on the huasheng) isn't as bad as everyone makes it out to be. The carb is the bottleneck.
Just earlier this week i changed the stock carb on my 49cc OHV 4stroke Hauseng to the NT carb. The easiest fit as i has the cast inlet matched the port in the head. As the carb dimensions matched, the engine ran rich ( 4stroked). The NT is set for 66cc. I dropped the needle, top notch, and the engine ran smooth. Better idle and crisp right through the rev range.
the trouble is with synthetic oil is its expensive, so i use mineral oil, any oil, if u use gearbox oil or used engine oil, just be sure to mix it well with petroleum spirits before mixing it with fuel and always keep the tank moving
I have an extremely modified 2 stroke for fun and a 4 stroke for general use
Good video but the 2 stroke can be hot tuned after the carb is set to full drive it needs an adjusment when hot
Now this is how you do a side by side comparison
Read a few articles on this subject, each one said the 4 stroke can run longer than the 2 stroke for about an hour or so and the 2 stroke for about 30 minutes before over heating. If you have the budget to mod, 2 stroke. I prefer 4 stroke, regular gasoline and longevity is the deal breaker.
4 stroke will run for years and you can run it wide open for hours no problem. phatmoto for 2 or 3 years🍻
Ok, being a newb, ive got a couple of questions..... 1. Why doesnt the 2 stroke have a pull start? 2. Do both engines use a centrifugal clutch? I currently have a 4 stroke and love it. Adusting the valves, rejetting the carb and advancing the timing 2°, (also doing your clutch spring trick) and im doing an easy 30 mph on dirt and 37 on even pavement. And i weigh in at 220lbs! Whats your theory on exhaust? Straight or keep the muffler?
I built a 2 stroke and 4 stroke but sold the 2 stroke. I still ride the 4 stroke almost 2 years later with no maintenance but oil change and carb change cause I let the gas sit in the carb . Carb was $22
Oh! YT comments about motorized bikes Well the 2 stroke's instruction sheet always says to install the engine on a "V" framed bike for best fitment. It pretty much locks the engine in place which you can't say about the cruiser frame. Also that 4 stroke gearbox is 3.2:1 gearing versus the 4.11:1 on the reduction on the 50cc 2 stroke. Fairly big difference in how either bike will climb hills You would be better to buy a 54T sprocket for the 4stroke to even this reduction ratio. Also note that the "5G" type Glimer belt transmission on the better quality 4 strokes last longer.
All of the 2 strokes have eccentric output sprockets and I noticed the 2 stroke in this video was 'warbling" because of that off center sprocket. This has been an issue with the 2 strokes for years, it's what eventually damages the left side spokes through the rubber clamping ring rag-joint. The 2 strokes also benefit from a smaller main jet and running 32:1 fuel : oil. Remember to grease your primary gears every 300 miles or so..
Hello from Romania, one question for you ... Would you prefer more a 4 stroke kit or the 2 stroke ? I'm about to build one and I have doubts about the 4 stroke and the clutch issues ... And for the 2 stroke I have doubts about the noise ... Could you help me out with a suggestion ? I enjoy riding on hils and valleys ... Which one
would be better for me ? Thanks
Worth it I love mine 2. Stroke
What did you customize to make yours as fast as it is? And what fuel/oil combination did you use in the beginning and after a few tanks?
In terms of power, the 2 stroke seems to have more horsepower, but lower torque, meanwhile the 4 stroke is flipped, which makes it slightly better for going up hills or pulling a trailer (not by much though)
Hy. Is there a way to make a motorized 50cc setup demountable from the frame and put back in like 5 to 10 minutes after airplane transport?
You also need to take into consideration what mix he was running in the vid for the 2 stroke, I run 50/1 in my bike and I can tell you it would put the stops on both of those bikes
thats how mine was till it blew up
@@clutchplox i use around 32/1 i belive. its winter in canada so i havnt been riding it and forget what the mix is right now
40:1
Great comparision. I would like to build a 4 stroke. How heavy are would these bikes be? 2 stroke vs 4 stroke?
Almost not comparing Apples to Apples because the four stroke transmission is geared so high. With a 44 tooth sprocket they have no of hill climbing power whatsoever. But should do 35 on flat ground. Also that's a pretty nice engine mounting bracket for a generic kit.
I had a GX35 4 stroke grass cutter engine bought it from the junkyard
Is the sprocket the same on both? I am replacing a 2 stroke kit with a 4 stroke kit and my chain hasnt stayed on long enough to ride
Not sure if this applies to motor bikes but on old 2stroke motorcycles and dirt bikes you usually get non-synthetic oil with 2stroke additives. Non-synthetic makes for a cleaner burn, as in 2strokes need to burn its oil.
Also fun fact: rotary’s (wankle rotary) are technically 2strokes
Watching this I'm glad my second bike will be 4 stroke but still the biggest prob is they still come with shitty little 2 ltr tank had to spend extra for a 3 ltr to find you can get a bloody 4 ltr so that with a 36th for now an a jackshaft kit later both th 2 an 4 stroke speed won't be an issue
I've been thinking of doing a motor bicycle for a while now. I'm aiming to build a sporty bike with as high power to weight as possible, seems like the 2 stroke is more ideal for my plans. Looks like I'll just get as light a bike as I can get, and slap as big a 2 stroke I can find on it. 😆
Get a YD100 with a performance carb and a better cilinder. Also get a new head if you can
please tell a location that that has a pull up pump that is non ethanol? .... pretty sure all pumps have some ethanol and up to 10 or 15% in summer months..... farm fuel is bulk order, not at pumps and has been for a good while....
did the hyper cruiser come with a 3 piece crank assembly or was it a one piece?
Great video! what is your personal favorite between the two?
I would like to see you all out power outing straight up hills uphill climbing steep same CC same sprocket big that would be killer.
Nice
Excellent views . The 4 stroke is the best .7/31/2021
It would seem the 4-stroke would benefit me better... I need it for going in and out of town.. it’s not start and stop it’s more just straight line and the 4 stroke seems to have a higher top speed...
You forgot to mention the bigest performance mod you can do to the 4 stroke kit... Exhaust. The stock exhaust on both kits are crap. The 2 stroke would benifit more but it still makes quite a difference on the 4 stroke.
What exhaust do you recommend?
When it comes to small engines like this, I think the 2-stroke is the best option. Less complexity (no valves, cams etc) and a single cylinder 2-stroke engine will run smoother than a single cylinder 4-stroke as there are more power strokes per rotation of the engine. They also make more power for given displacement again because of more frequent power strokes.
I agree but they don't run smoother.
Lmfaooo
When you go off on a paragraph-long schpeel, for fun.
On Earth, 4 strokes are a helluva lot 'smoother' running engines, & will last much longer.
This is what I was looking for. Now can we get 66cc vs 79cc.
You want a side by side with a typical 80cc (66) and a 79cc predator? That can be arranged. Let me finish the ”Pimp My 50cc” series, then I'll do that side by side. Anything I might have missed in this video that you'd like to see in the next? Thanks for your contribution to the community 👍
Southern Custom CC I can wait I have patient to watch your videos. Thank you for the recommendation
Just do a the new 100cc(80cc, actual 78.5cc) vs the 4 stroke, I prefer the 2 strokes easy and lightweight motors, also cheaper
Southern Custom CC The new big bore 2 stroke engine kits come with a displacement of 78.5cc instead of 66cc. Look for a "YD100", "T100", "Zeus", "Zeda100 Firestorm" etc
@Mario Salinas that's a bummer my dude, those 78.5cc 2T are real torquey and easily do 40+mph if done correctly on stock parts, while achieving 50-60miles per tank.
Could you put the link of where you got the 4 stroke at? Please
Who is the best 2 or 4 stock engine kit.please tell me request.
what transmission upgrade is good for the 49cc 4 stroke? best carb? shifting kit?
Did you make a build video for these bikes?
That intro music gave me Biaheza vibes
can you please provide us an affiliate link for the bicycle used in this build? Also, what is the gearing on this bike? Is it a fixie, a 7 speed, or 21 speed?
Gatta say, the 2-stoke sounds more fun. They both seem to perform about the same.
Awesome video. But...you can step it up like I did. Got a similar bike from my in-laws. Got the 212 predator engine, torque converter, and a stage 1 kit. After some reinforcement at the welds, it does very very well for a few hundred bucks!
Nice! Careful though....its not called a death row set up for no reason! I hope you have a lot of fun! Be safe, and thanks for watching!
Nice vid though 👍👍
I used a 4-stroke weed wacker motor and attached a gear to the crank so it could attach to another gear on the crankshaft so I could just have direct power to the wheels using the already existing 21 speed for my mountain bike so it's like I have a transmission and I can go faster or slower without using the throttle and instead of using a twist throttle I used one off of an old snowmobile and I've been able to hit 45 mph with it with no issue my only issue was waiting for my dad to be free so I could use his welder bike crankshaft and to the weed wackers clutch and I just grilled some holes for some brackets to mount the motor and I was able to move the fuel tank up to the top bar of the bike
Also i removed the pedals and put pegs on the front rim to place my feet and a one of those little generators that rub against the tire to power a light and i did a second to power a phone charger
And thankfully I can just use the pull start with key ignition to allow electricity to go into the spark plug did I picked up from AutoZone
And I also don't have to pedal it to get it moving
Are the crank arms shorter on the one bike or is that just me
We know already that 2 stroke wins but it will be fun to see how much better is a 2stroke
For sure, 49cc and 50cc are practically the same size, but just for the record, we are talking 49cc here. And it would have been nice if the gear ratios on both bikes would have been specified.
Specifically 4.11:1 for the 2 stroke and 3.2:1 for the pocketbike X7 transmission, best to run a big rear sprocket (54T~60T) on the pocketbike transmission.
Hello do you have a link for the bike that you used?
There has to be a problem with your 2 stroke I installed 3 and went over 35 mph on 24 inch wheels(i gotta say I weight about 150lbs for 6ft tall) and I suppose the 26inches would make it even faster but most certainly will impair the ability to go from 0 with only the engine power(w/o pedaling)
I had the two stroke one and it was able to push like 35mph
I’m not sure if he had taken his governor off his
@@aydenparkinson8874 mine came from the most Chinese company ever and didn’t even come with a governor, downhill it was going almost 40!
Yeah my two stroke does 28.2 mph!!! Only 49cc uberscoot. But I think I seized the motor. I hope it’s just the carb. I ordered a good carb to change it this week.
I’ve got a 4 stroke and it does 35 ez
Mine is like 45,6kmh
How long can i ride on a 2 stroke engine? 80 % speed for 30 mins is safe or willl the engine overheat and damage?
I bought a 2 stroke 80cc thinking that I would get better power but go the same results as you but I’m 60lbs heavier and I put the kit on a 24 inch tire bike if i were to do it over again I would do it on a 26” bicycle and gotten the four stroke I got the two stroke to save money but by the time I upgraded all the bad kit parts I paid more than what I would have if I got a four stroke and the carb needs to be cleaned Once a month or it gets stuck both on stock and upgraded carbs
Muito top as duas parabéns
2 mods for the 4 stroke. Rejet carb and remove intake and exhaust skirts. Covers 1/4 of both. Has integrated head so no milling for compression.
What about removing the governor....
william gosvener all the Chinese huasheng ones I’ve seen didn’t have a governor, I’ve heard the legit Honda gxh50 does tho
Meof Myof answer is the 79cc if you’re looking for power definitely.
I love the idea of these, but where I live, this is a motorcycle that needs a tag, insurance, and an add-on for your drivers license.
This is a fantastic video. I am working on a bike build utilizing a high power AGNI 95 (Lynch) DC Electric motor. Any input or comments are appreciated, thank you.
@Nomore Illegals please Thank you so much for that information. I only have limited funds so for now I already have an AGNI motor rated @ 20kw of output max, but I'm going to run it off either a 5000watt pwm controller(48v), or a 1,500 watt brushed motor controller with twist grip throttle and a digital readout. I have a 48 volt, 20AH Lithium battery rated for 2000 watts continuous. What do you think about my plan?
