The characters included in the charging information IC include characters such as "turn off the power after charging" or "turn off the power after X minutes". In one example, the display unit DU displays the charging information IC on the end screen ES using the characters and icons shown in FIG. If the operation unit 18 is operated again in the display state of the end screen ES, the command to turn off the power of the electric component EC for the human-powered vehicle is canceled, and the screen transitions to the main screen MS again for the human-powered vehicle. The electric component EC may be configured to shift to the operating state.

In the second example, when the remaining amount of the second battery BT2 is less than the first value in the operating state of the electric component EC for the human-powered vehicle, the control unit 22 sets the remaining amount of the second battery BT2 to the fourth value or more. The operation of the operation unit 18 is not accepted until it becomes. The fourth value is the same as or larger than the first value. The fourth value is, for example, 80% of the full charge. The fourth value can be configured to be changeable by the external device ED. The fourth value may be a fixed value. The notification unit 14 may notify information indicating that the operation of the operation unit 18 is not accepted when the remaining amount of the second battery BT2 is less than the first value in the operating state of the electric component EC for the human-powered vehicle. ..

-The type of the human-powered vehicle A can be changed arbitrarily. In the first example, the human-powered vehicle A is a road bike, a mountain bike, a cross bike, a city cycle, a cargo bike, or a recumbent bike. In the second example, the human-powered vehicle A is a kick skater.
