I have been trying to rig up a gas powered engine on a bicycle until a friend gave me his old garage door opener with a 1/2 horsepower electric motor in it. Will 1/2 HP be enough or do I need far more than that? I will get pictures up in a few...
I wouldn't bother with the garage door motor though buddy more trouble than it will inevitably be worth. Ifyou want to got lecky look at some of the Cyclone kits.
