Ok so i want to build a moterized bike and i thought it would be awsome to take a shifter kit/JAck shaft from sick bikes parts but instead of having the chain go into the frame i would have it go out the to the back rack where i would have an engine mouted, i thnk about 4 horse...OR is the shaft from the engine spun the right way i could go strait to a free wheel on the front sprocket. Is this a good idea

It will have a killer chain, but why not?

What do you mean by killer chain? Are you just talking about the chain between the engine and jack shat.

Yes, I meant that in a good way.

4 hp may be a bit much, but it's all about having fun, and experimenting.

ok i might do that then if i do this ill use an old engine or buy a new one and get the shift kit mabey buy one of those $25 bike racks or build my own. With standard gears and a 4 horse power moter how fast do you think it would go

Scary fast ... I bet you could do an honest 45 or 50 with the right gearing.
