tried searching, didn't find much. i want motor.
Surely someones knows, and before i start i know you guys are all for pedals and human power, but i am doing this to a spare crud bike.
i have all the skills, parts but no know-how.
Looking at putting a motor of some sort, probably whipersnipper or chainsaw onto an old mountain bike.
I am not sure which would be the correct/easiest method, which engine would be the best and easiest, also if anyone has pics of on they have built.
We thought about welding a bike peg onto the whippersnipper drive shaft and then placing the peg onto the tyre, when the peg turns so does the wheel, but this would wear out the tyre and become ineffecient.
so i though if i want to incorporate the pedals aswell, i could use an extended axel bolt and use two rear sprockets, effectively two chains, one for the pedals and the other onto the engine.
What would be your plan of attack?
