I prefer two stroke engine, it's a simple engine with low maintenace, more power, although some people do not like the smoke, i use low smoke oil and it seems there is almost no smoke while my bike running.

i'm sorry, i'm newbie and my english is bad, I hope there is no misunderstanding.

Depends on what you want. For me it's reliability so Robin 4 stroke rack mounts are the way to go.
I almost have to invent maintenance chores, lol.

Default Re: 2 or 4-stroke

I've had several two strokes and am looking to try my first four stroke this fall. I think you need to do some self evaluation... money tight? 2 stroke kits are less expensive unless you want to spend a bunch on aftermarket upgrades... jackshaft kits and expansion chambers, etc. The 2 strokes look better in the frame and take up less room, so some bikes can accept a China Girl when there isn't enough room for a four stroke if you want to go in frame. As Pablo said, the China Girl was designed for a bicycle. How mechanical are you? Or how mechanical do you want to become? Some people just want to get in their car and turn the key with no interest in how the car works, learning to change the plugs and oil, changing a tire or maybe even a little mechanical work... brakes or clutch perhaps. 2 strokes take a little more maintenance (I am told) which for some is a pleasure and for others a pain. I think some of the people who get a bike kit and don't want to do anything to keep it in good order would have done better to get a Chinese scooter or just drive the car. Bikes with motors are kind of primitive machines which appeals to me and is part of the allure... like the early motorcycles. Having your own bike of your choice & motor which you put together can be a great satisfaction and a reflection of you. So, don't just look at what was right for somebody else, but do a self check and go from there. You can always start out with a 2 stroke sticking to a pretty tight budget and later move on to something better for you if you decide it doesn't suit you or your money situation improves. A basic, bump start manual clutch 2 stroke is fine for a young person especially. Some of the older riders want a pull start and an automatic clutch, little maintenance, all of which comes with a price tag. Hope this helps.

As my preference, a 2smoke, I am also a budget minded student, mind you it's highschool, but I have a 6mile each way ride and the rack mount leaves no room for books, report's, presentations, etc. also without getting another gas tank the 2 smokes have a longer range as they come with a larger tank. Also with more people using the mostly standardized 2smokes more help is available, as opposed to the huge variety in 4 strokes. You will have a large repair once in a while no matter what engine you choose and 2smoke parts are usually cheaper, heck just an engine is under $100, just my 2cents.

Default Re: 2 or 4-stroke

I have zero experience with motors on bicycles. I am just getting into this sport.

Lots of experience with motorcycles, 2-strokes, and 4-strokes.

2-stroke - Lighter, cheaper, simple, good power/weight ratio.

4-stroke - Heavier, more expensive, tends to be more reliable. You need 50% to 100% larger motor to get the same power as a 2-stroke.

Mixing gas and oil is no big deal. Unless you don't have the oil. If you're one of those types that buys gasoline when the car is on "E" empty, maybe 2-strokes are not for you. Or you can carry a bottle with 2 oz of oil. Put in some gas, some oil, more gas, put on the cap, rock the bike, ride. I have 2 gas cans for 2-stroke premix, 2 gas cans for 4-strokes and cars.

NOISE - Here is a real key item. Young riders often want "Hey look at my loud bike!" (Dig me riding!) Loud motors are more powerful! Loud pipes save lives! I've been riding motorcycles for 40 years, I still get mad when some moron goes by with loud pipes. It's just bad for the sport.

The truth is loud motors anger a lot of people. I'd rather have a quiet bike that is more stealthy. Almost every off-road riding area I used as a kid was closed down due to noise complaints. Now you want to ride a street bike out of your neighborhood every day, I suggest making the bike quiet.

I have a 2-stroke motor from a busted weedwacker, that runs great. So my first bike / motor combo will most likely be a 2-stroke. Making it quieter is going to be a challenge.

If you like enough power and reliability, light weight, get a Tanaka 40. With a mountain bike your option will be a rack mount.
Friciton drive-easy to install simplicity, robs power, not good in rain
Golden Eagle= belt drive,dependable quite drive train, relativel easy to install, only single speed, relatively more expensive.
Staton Chain Drive-Have new 7 speed drive train, good on hills, fast on flats, dependable, lifetime warrany on gearbox. Downside hevier than most,one of the more expensive, in my opinion you get wht you pay for.
