Background Hub Motor • Easier to retrofit a non-ebike • Not-ideal wheel weight distribution • Direct drive • Less chair wear Mid Drive • More torque • Better weight distribution • Can take advantage of the gear train • More easily integrated with pedal force feedback 10

Background World wide e-bike demand is increasing e. Bikes are a clean and efficient alternative mode of transportation. 11
