    I want to put a mini moto engine in a mountain bike. I am going to put the engine inside the frame then take the pedals off the crank shaft and am going to have a sprocket carrier machined to fit the crank shaft on the left side of the bike with a chain going from the engine to the left side of the crank shaft so I can still use the gears on the bike. can anyone see any problems with this?

    What size sprocket will the mini moto engine have?
    Will you use a reduction transmission?
    What size sprockets/cassette do you have on the bike now?
    There are some handy gear calculators on this site to do the math to optimize your reduction.
    I built a mini moto engine powered bicycle but drove the front wheel with v-belt & pulley...ran strong for about a year or two.
