Abstract: 

Only physical training allows to improve the effort management on a bike. Electric bikes (e-bike, pedelec category) add a torque when travelling difficulties appear. But this facility does not manage the energy developed by the cyclist. A series hybrid type drivetrain for bikes, well known in the automotive field, is presented in this paper which improves the management of human efforts. The first results show the advantage of this solution compared to conventional self-management on the basis of a simple model of untrained cyclist behaviour. The paper argues that an energy storage device associated to series hybrid drivetrain will ensure an improved balance of the human effort management. However, the efficiency of this conversion chain must be high to maintain its benefits. In this context, a first sizing of an electric generator is introduced.

Keywords: 

human powered vehicle, series hybrid, human energy management, human fatigue model.
