Didn't get how it's moving the wheel without chain

  Pedals charge battery, battery drives motor. 5% less efficient than chain drive.

    I wonder if this would remove some of the design constraints seen in folding bikes. The frame, wheels, and handlebars are the main annoyances; but I feel the gear and chain system limits the frames. Every folding bike is somewhat bulky, and I’d love to see one that neatly packs to the size of a small personal overhead luggage without sacrificing safety.

      belt drives and chains are on the same plane as the frame, so I don't think it would allow much more design freedom to reduce bulk. It may afford other design freedom, but I don't think bulk reduction will be significant.
