A New concept for Motorized Bicycles

I too have been waiting for the Revo power wheel. Seems very simple and not too expensive. With just one speed it would not have much hill climbing ability. I still think it would be a great addition to a electric hub motor on the back wheel. Heavy bike however when you wanted to use bike ways that don't allow motorized engines you could switch to electric. Possibly a good engine to tour using a recumbant. Many possibilities. I think it will be a great success.
