ABSTRACT:
Several embodiments of pedal operated vehicles such as bicycles wherein electric motor assist is provided in response to the pedaling force applied by the rider. However, a number of embodiments of malfunction detection devices are disclosed and which will preclude the application of electric motor assist if the system has been disabled or if it is not operating properly. In addition, a start up routine is also disclosed that prevents the sudden application of electric power upon starting of the system.
