A human-powered vehicle control device includes an electronic controller and a first operating portion. The first operating portion operates a human-powered vehicle device. The electronic controller controls a supply of electric power from a battery to the human-powered vehicle device in a first mode. The electronic controller controls the electric power supplied from the battery to the human-powered vehicle device in a second mode to be less than the electric power supplied in the first mode. The electronic controller switches the first mode to the second mode upon determining the first operating portion has been operated by a first action while in the first mode. The electronic controller does not switch from the second mode to the first mode upon determining the first operating portion has been operated by the first action while in the second mode.
