Abstract
A simplified mid-motor drive system includes all necessary electronics and allows for throttle-only operation of the motor. The mid-motor drive system includes an arrangement of uni-directional drive connections (i.e., sprag clutches) between the motor and the pedals which allows each to operate independently or in conjunction, and allows simple modifications to gear ratios of packaged drive systems in order to adapt to regulatory requirements of different worldwide territories.
