2 Stroke VS 4 Stroke SIDE BY SIDE Comparison 50cc Motorized Bike

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!!!

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

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

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

I'm watching this video because I'm getting my first 2 stroke soon I can't wait for it to arrive.

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 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!

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.

2 strokes are more fun, fast, and loud. 4 strokes are a bit slower but generally easier. Depends on what you want.

[jeffries]

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

[erendyalatorre]

This is the best video comparison anyone has ever made.

[lincoln]

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

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.🍻

[codelicious]

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!

[lexuses]

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

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'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.

[jaredwilcox]

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.

[ronaldreinhardt]

Probably the best comparison of the 2 and 4 stroke engines...helped me a lot!!!

[vincentmorelli]

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.

[mikko]

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.
