The characters included in the charging information IC include characters such as “Turn off power after charging” or “Turn off power after X minutes”. In one example, the display unit DU displays the charging information IC on the end screen ES using characters and icons shown in FIG. Note that when 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 human-powered vehicles is canceled, and the transition to the main screen MS is performed again for the human-powered vehicles. The electric component EC may be configured to shift to an 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 human-powered vehicle electric component EC, the control unit 22 causes the remaining amount of the second battery BT2 to be equal to or greater than the fourth value. Until that time, the operation of the operation unit 18 is not accepted. The fourth value is the same as the first value or a value larger than the first value. The fourth value is, for example, 80% of 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 human-powered vehicle. .

  -The kind of 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. In the second example, the human-powered vehicle A is a kick skater.
