A bicycle includes a frame, a charging circuit carried by the frame and configured to capture energy associated with movement of the bicycle, a power module carried by the frame, and a switch disposed electrically between the charging circuit and power module. The power module, in response to an indication that the bicycle is travelling downhill, closes the switch to enable energy transfer between the charging circuit and power module.

A control system is provided for controlling an electrical component of a human-powered vehicle in accordance with a swivel state of a riding portion and a carrier. The control system includes a sensor, an electrical component and an electronic controller. The sensor is configured to output a signal corresponding to a pivot angle of a pivot portion provided between the carrier and the riding portion located between the carrier and a handle. The electronic controller is configured to control the electrical component in accordance with the signal output from the sensor.

A triboelectric nanogenerating device is configured for providing an electric power to an electronic device and the triboelectric nanogenerating device includes at least one scaly triboelectric membrane configured for providing the electric power to the electronic device by frictional electrification. The at least one scaly triboelectric membrane includes a keratin and a polyvinyl alcohol, the at least one scaly triboelectric membrane has a first triboelectric surface, and the first triboelectric surface of the at least one scaly triboelectric membrane includes a plurality of scaly layers. Each of the scaly layers is arranged in order and extends along an orienting direction. A distal end of each of the scaly layers has a plurality of saw-tooth structures.
