| | Re: Bicycle Motor i like the 4 stroke b'cause i am familiar with the way it works on my lawnmower. it's very forgiving and sturdy and it idles slow and smooth. also i like to be able to start the motor without moving the bike. i just wish that it fit and looked cool like the 2 stroke |

| | Re: Bicycle Motor The question was based only on cost, for that reason I chose the 2 stroke. When comparing 2 strokes and 4 strokes of equal price, you can buy a race ready 2 stroke that is far superior to the china motor and it would have it all over the normal 4 strokes for lawn mowers. I have been mixing gas/oil for years and still do every week for my ultralight so that is normal. For distance, I just carry an extra 1/2 gallon or more. When there is a quality time tested frame mounted 4 stroke, then I will change my thinking. |

| | Re: Bicycle Motor I voted for 4 stroke. If costs were equal, I would rather have an in-frame 4-stroke kit. Mostly because I'd rather not have to mix oil and gas. Also they're cleaner burning, smell less, etc. Granted it's a tough choice seeing as the 2 strokes are more powerful. |

| | Re: Bicycle Motor It depends Cruiser if we're talking about any 2 cycle motor. If it a chinese motor vs. a titan. Hands down it would have to be the 4 stroker. However if we're talking about my motor vs. the Titan then hands down I'm picking my 2 stroker. I love the fact that I can rev the living daylights out of my motor and not worrying about it. Plus the power can't be beat for my 50cc motor and up grades are available. I.E. 9.8hp cylinder, carbon fiber reeds and stiffer clutch springs. |

Wait...your motor is only 50cc? Dang. |

| | Re: Bicycle Motor down here it is a matter of reliability for me. the 4 stroke titan i have not had to do a thing to and i ride every day. i get up to 36mph on it but ussually cruise at about 29 to 30 mph which is plenty quick with the roads here. i have to say i do miss not having any extra's i can add to it. i look forward to new items to hop it up a little when they become available. for now i ride it stock with a 40 tooth sprocket and love it. |

| | Re: Bicycle Motor While both types have their own advantages and drawbacks, I like the 4 stroke. My Whizzer is so American;relatively heavy, loud and inefficient. My Puch 2 stroke moped is smaller, quieter and has a more "modern" look, even if some say it looks gay. The Whizzer and the electric Ford Thinkbike are all that's currently running though. So 4 stroke it is!
