ABSTRACT:
Several embodiments of electric power assisted bicycles wherein an electrical motor is employed for assisting in the pedaling of the bicycle. The embodiments all include an arrangement for changing the state of the electrical power in response to pushing of the bicycle. In some embodiments, the circuit for the electric motor is opened when the bicycle is pushed rearwardly so as to avoid undue resistance to the pushing as might occur due to the fact that the motor would operate as a generator under this condition and provide an electrical load. In other embodiments, the electric motor is energized upon pushing so as to assist in pushing the bicycle.
