Abstract
A bicycle rotation detecting device is provided with a first electrical connector, a second electrical connector, a rotation detecting circuit and an output part. The second electrical connector is electrically connected to the first electrical connector by an electrical path. The rotation detecting circuit detects a waveform of alternating current in the electrical path and produces a rotation detection signal. The output part is electrically connected to the rotation detecting circuit. The output part outputs either the rotation detection signal of the rotation detecting circuit or a signal based on the rotation detection signal of the rotation detecting circuit.
