Abstract
A device is provided for regulating an assistance power of a bicycle fitted with an electrical power assistance machine. The device includes a rotation-sense detector, a speed sensor, and a central electronic controller. The detector is arranged to detect a sense of rotation of pedals of the bicycle. The speed sensor is arranged to measure a speed of a wheel of the bicycle. The central electronic controller is configured to calculate a total power of the bicycle from the measured speed, and to determine a power setpoint of an electric motor from the calculated total power, the sense of rotation of the pedals, and a power assistance factor selected by a cyclist of the bicycle. A method for regulating an assistance power of an electric power-assisted bicycle also is provided.
