Abstract
An electrically-assisted pedal cycle has a drive system with an input that receives drive from a pedal of the cycle and rotates about an axis; an output that rotates about that axis to provide drive to a cycle wheel; an electric motor that provides motor drive to the output; and a drive train that receives drive from the electric motor and the pedal and transmits drive to the output. Between cycle speeds of V1 and V2, where V2 is greater than V1, the drive train provides a continually variable transmission (CVT) by which the pedal cadence is controlled by the electric motor. Above a cycle speed of V2, the drive train disengages drive from the electric motor to provide output drive only from the pedal.
