Joules: Robotic bike rider

But you’ll look sweet, upon the seat, of a bicycle built for two. via Robo Living

The build resulted from a challenge by my son, a former pro bicycle racer, and is purely for fun. Could I build an electric tandem based on actually pumping the pedals? Would it climb the steep hills where we live? The result of the challenge is Joules, who sits on the stoker seat and does all of the pedaling.

Update: Carl sent in a link to more information. Thanks Carl.
