The detection unit 36 includes at least one of the switch 36A and the sensor 36B. The detection unit 36 is provided, for example, in the lock unit 24. The lock portion 24 is displaced from the unlocked position to the locked position by arranging the battery unit 40 at the holding position held by the battery holder 10. In one example, the electric actuator 26 displaces the lock unit 24 according to the detection result of the detection unit 36. Specifically, the control unit 32 controls the electric actuator 26 so that the lock unit 24 is displaced from the unlocked position to the locked position according to the detection result of the detection unit 36.

The control unit 32 controls the electric actuator 26 so that the lock unit 24 is displaced to the unlocked position in response to the release signal. The release signal includes information for releasing the lock of the battery unit 40 with respect to the battery holder 10. The control unit 32 receives a release signal from the external device ED1. The lock device 20 further includes a receiving unit 38 that receives a release signal. The receiving unit 38 may receive the release signal by wireless communication, or may receive the release signal via the communication line. In one example, the receiving unit 38 receives the release signal by wirelessly communicating with the external device ED1. The receiving unit 38 transmits a release signal to the control unit 32. The external device ED1 includes at least one of a key unit for a human-powered vehicle, a smart device, and a personal computer. Smart devices include at least one of wearable devices such as smart watches, smartphones, and tablet computers.

The receiving unit 38 is provided in the battery holder 10. The receiving unit 38 is provided in the battery holder 10 so that, for example, the release signal transmitted from the external device ED1 can be suitably received. In one example, the receiving unit 38 is provided so as to be exposed to the outside with respect to the frame A1 of the human-powered vehicle A. When the receiving unit 38 is provided so as not to be exposed to the outside with respect to the frame A1 of the human-powered vehicle A, a through hole is formed in a part of the frame A1 or a part of the frame A1 is manufactured of resin. Is preferable.

The human-powered vehicle A further includes a notification unit NU that notifies the mounting state of the battery unit 40 with respect to the battery holder 10. The mounting state of the battery unit 40 is detected by, for example, the detection unit 36. The notification unit NU notifies the mounting state of the battery unit 40 by, for example, at least one of light and sound. The notification unit NU includes at least one of a display unit SC (see FIG. 1), an LED (Light Emitting Diode), and a speaker. In one example, the control unit 32 causes the notification unit NU to notify the warning information when the battery unit 40 continues to be arranged at the holding position after receiving the release signal from the external device ED1. Further, when the battery unit 40 is not arranged at the holding position, the control unit 32 stops the supply of electric power from the battery unit 40 to the component CO1 mounted on the human-powered vehicle A. Therefore, the component CO1 is not driven when the terminal 44 of the battery unit 40 is electrically connected to the connector 30 and the battery unit 40 is not arranged at the holding position.
