Re: If you had it to do over again ...
hey spud. Welcome. It all depens on what you want to use ur bike for? My 1st build was a 21 speed mountain bike. And ill admit i never changed gear.
I think that if you got a old mountain bike the ones with the larger frame they engine should just bolt staigh on and be alot less complicated.
who needs a car wen u can have a motor bicycle
