Abstract
A power assisted, manually operated vehicle wherein the amount of energy required for the assist is reduced and the riders sensation is improved by continuing the application of power during times when manual power is still being exerted but no manual power is transmitted to the propulsion device because of the geometry of the transmission system so that the cyclic variations and amplitude of the power assist are reduced.
