A bicycle signal output device comprises a magnet (11) structured to be mounted to one of a stationary part and a moving part of a bicycle, a coil (12) structured to be mounted to the other one of the stationary part and the moving part of the bicycle, and a signal generating unit (14) that operates using electrical power generated by the coil (12) in response to relative motion between the magnet (11) and the coil (12). |
