Re: New Biker
I thought about doing a tandem one day as well. You could put a left side crank on the front and back with freewheels in the left side crank. Then you could keep your front peddles. I've got a Staton Inc crank drive kit on my bike. Staton is very good at building custom parts. You need to read your local laws for the engine size. Otherwise you may have to build in a motor driven cycle category.
