A hybrid motorbike is provided which is powered by human muscle power on pedals and supplemented by an electric motor with the current generated by a fuel cell on the motorbike. The motorbike has a crown gear driven by muscle power, and a planetary-gear carrier with planetary gears transmitting power from a pulley connected to the motor by a belt to the ring gear of a bell attached to the crown gear which is attached to the drive wheel of the bike. The fuel cell and a battery and controls may be contained in an exchangeable module in the triangular space formed in the frame of the bike between the front wheel and seat. The bike has sensors to determine the speed and load placed on the pedals which is transmitted to a microprocessor programmed to control the electric motor according to the load on the pedals and the speed to provide the desired assistance to bike.
