Abstract
A bicycle has an electric motor and attached single or multiple sprockets, gears, chains, belts, shafts and mounting brackets. Outer sprockets are independently turned by either the motor or the pedals, and these outer sprockets then turn an inner sprocket which drives the drive chain and turns the rear wheel. Either the motor or the pedals, or both, may propel the bicycle. The vehicle also includes a means for detecting gear shifting and thereupon reducing power to the motor for a short time interval.
