More Information
Summary:The invention provides an electrically assisted bicycle having a simplified construction for reliably effecting a change-over to regenerative generation of power. The bicycle comprises a human power drive mechanism using a human drive force, and an electric drive mechanism adapted to receive power supplied from a battery 13 for driving a motor 32 with a drive force in accordance with a value detected by a torque detector 41 for detecting human torque of the human power drive mechanism. Electric power is produced by regenerative generation when cranks 6 of the human power drive mechanism are rotated with a number of revolutions smaller than is needed for causing the bicycle to run on a level road at a speed detected by a speed detector 40.
