Abstract
A bicycle drive system includes a bicycle drive unit and a bicycle battery unit. A first power supply path supplies power from the battery unit to the drive unit. A second power supply path supplies smaller power from the battery unit to the drive unit than the first power supply path. In a case where the drive unit and the battery unit are connected by the first power supply path and the second power supply path, the bicycle drive system is configured to be switched between a first state, in which the battery unit stops supplying power to the drive unit via the first power supply path and supplies power to the drive unit via the second power supply path, and a second state, in which the battery unit supplies power to the drive unit via at least the first power supply path.
