I have a Poulan Weed Eater 20cc motor. I know its not big but I just want to be able to build a motorized bike. I am not sure wether or not to make it a friction drive or chain drive. I am kind of leaning toward chain drive due to slippage in the wet with a friction drive. I also dont know how or where to mount the motor? Over top the rear wheel? In between the frame? Oh, and one last thing, I dont have a welder and I would like to build the whole thing without welding and i would like to be able to disengage the motor so i can return to normal pedaling.
