I would have to try a model before I give them money. It looks too easy to go over the handlebars. Or is that why it is geared so low and has no leverage, you can't go fast enough to hurt yourself.... Light weight is the main attraction but wet weather would cut use a huge amount. DIY 3D printing of fiber composites could make it a success. I wonder if inductive charging of super capacitors to supply energy for climbing hills would fix the gears/leverage problem.
