Adding a small motor to a bicycle?
So I have been planning on building an electric bike that I can ride to the train, and take the train to work. I am now thinkng about putting a small gas engine on a bike instead.
Does anyone know of any kits? Something that would sit on the rear rack, and be pretty quiet, pretty light weight, and pretty stealth (I don't want a big, ugly engine out there for everyone to see- I'd prefer it be hidden in some sort of case or something).
