2-Stroke vs 4-Stroke Motorized Bicycle (GoPro)

[@dehoedisc7247]

3 more significant differences : 1) the 49cc 4-stroke engine has a forced air cooling fan that is effective at all RPMs,the 2 stroke has no cooling system, it relies on moving the bike through the air 2) The 4-stroke has a proper lubricating system, the 2-stroke has a very poor lubricating system , so the 4-stroke should typically last much longer due to less wear 3) The gas mileage is much better with the 4-stroke. Period.

It just accomplishes this in two strokes of the piston or one revolution of the crankshaft. And of course the four stroke does it in four strokes of the piston or two revolutions of the crankshaft.

I have gone up to 37 mph on a huasheng 49cc 4 stroke. On the crappy centrifugal clutch that sucks and can leave stranded at any moment leaving u to pedal ur butt home. But with a better transmission like the ezqmatic you can get excellent reliability from the engine. 2 strokes are good you just have to carry around 2 mix oil around with the tank to mix it not a big deal but something you got to do.

Great advice! There is an engine kit which fits for everyone, whether it's 2 stroke, 4 stroke, or electric. There are advantages and disadvantages each option, and should be taken into consideration when choosing an engine kit. All of our engines are intended for recreational use, and are not intended to be used on public highways or roads.

2-Stroke - All the power is in the top end, use more fuel, noisy, have to remember to pre mix your fuel, less reliable and harder to start in the cold. 4-Stroke, More torque and bottom end power, quieter, more fuel efficient, only have to remember to keep engine oil topped up, much more reliable and the most important thing... they don't smell as nice as 2-stroke ;) I am by no means opposed to 2-stroke, I actually love the things! I really do think they are better suited to high performance motorbikes rather than tiny bicycle engines though, especially if you live in the UK and want to get away with riding them around illegally without getting caught by the old bill :) Plus, from the figures I have seen quoted the power difference between the same capacity 2-strokes and 4-strokes is negligible, they are very cheaply made an are not tuned. Only when you start to polish ports, tweak carbs, filters, and expansion chambers (in the 2-stroke case) will you start to notice differences. Maybe if Stan Stephens starts doing a bicycle engine tuning service/kit I will be interested in the 2-stroke option LOL

Now I know that my "1990 vintage Hyper motorized bicycle" is a 2-stroke one. I bought it just recently from a local pawnshop for $380.00, "as is." I had trouble turning on the engine, though, because I didn't exactly know how. I've watched another video on how to turn it on, including yours, today. Also, I didn't use a mixture of oil and gasoline on it...because I wasn't too sure about that. For a period of about 3 hours, I tried making it work. 👉 PROBLEM: They sold me the bicycle with a couple of wires loose. The one that connects to the "throttle" was disconnected. I connected one of the two wires to the blue wire that leads to the CDI box. Also, the white wire was disconnected, but I now know that it doesn't have to be connected to anything because it's optional and because it is sometimes used for connecting lights to the bicycle. 👉Another problem that I encountered was that both the gas line and the little gas filter started leaking. I need to replace those parts. 👉In the end, I decided to just come home peddling my vintage motorized bicycle, instead. Thanks for all your vital information... and for enlightening me. From, "Curious Joe" 😼👍

The other problem is you can buy a used motorcycle for $750-$800 on Craigslist. A year of motorcycle insurance is $60-$100 and a 250cc motorcycle gets about 75MPG. Plus, you can actually ride them legally on the road and they can keep up with traffic. Which makes the motorized bike more or less worthless. Now, an electric bike could be ridden on a bike trail and that's fun. But still the cost to build one is as much as buying a used motorcycle.

I have build a 2 stroke engine bicycle build four times but the 4 stroke is the best of reliability (Engine will always start), fuel efficiency is far better than the 2 stroke engine, quieter than the 2 stroke engine, little maintenance, gasoline burn cleaner than 2 stroke engine, very little to no vibrations, 4 stroke engine last longer than a 2 stroke engine. 2 stroke engine is noisy, it vibrate the bicycle and loosen the bolts & screws, it leaks oil, 2 stroke engine is a dirty engine cause you have to mix the oil with the gasoline together, doesn't completely burn all the fuel and sometimes it won't start. The only pros about 2 stroke engine is that the engine and parts are inexpensive, it can be easily modified or upgraded many ways (for faster speeds, aesthetics, etc., etc.) and it slightly has a bit more power than the 4 stroke engine (2 stroke engine - 66/80cc displacement, may get as little as 3 miles per hour to as high as 10 miles per hour faster than the 4 stroke engine (49cc displacement) even if both are using the same amount number of teeth on the sprocket.).

This is more of a comparison between two different models, not so much 4-stroke vs 2-stroke. The clutch has nothing to do with the engine. For example, our grass trimmer has a 4-stroke engine, and it uses a centrifugal clutch. It's also much more powerful than other 2-stroke trimmers I've used. It has a lot more low-end torque too.

What is the oil for two stroke engines???

[@davidbarts6144]

One thing only briefly touched on (wording was something like "4 stroke engines are better for the environment") is that 2-stroke engines have exhaust that is a LOT dirtier than 4-stroke engine exhaust. So dirty that even a tiny 2-stroke engine spews way more incompletely-burned and unburned hydrocarbons than even the largest luxury SUV with an 8-cylinder engine. Once you bolt a gasoline engine onto a bicycle, you no longer have a bicycle -- you have a MOPED, a type of motor vehicle. Like all motor vehicles, it requires licensing to be legally operated on the public streets and roads. If you build a two-stroke moped, it will be so dirty that it fails basic EPA emissions standards and can't be licensed. If you ignore these rules, a cop might notice your lack of a license plate, stop you, and write a citation with a nice, big fine. This is why bikeberry.com has disclaimers about its 2-stroke kits only being suitable for racing use.
