Hello everyone, I have been reading this forum for a month and decided to register. My wife and I both have brand new Schwin riverside 7 speeds. I am undecided about what I am going to do,but, at least 1 will be motorized. I am thinking about building a pusher trailer for the other. It will be powered by a B/S 3 hp motor to a jackshaft and will spin a 16 inch bicycle wheel. It will have 2 wheels and room for storage. Any Suggestions?
