Abstract
An electrically power assisted bicycle includes an electric motor, a detachable battery that supplies electric power to at least the electric motor, and an operation panel including a controller configured or programmed to control the display in a time display area and a built-in battery that supplies electric power to the controller. When the detachable battery is attached to the electrically power assisted bicycle and the electrically power assisted bicycle is in a power-on state, the controller is supplied with the electric power from the detachable battery. When the electrically power assisted bicycle is turned on from a power-off state in a state where a remaining capacity of the built-in battery is insufficient, the controller displays, in the time display area, information indicating that the remaining capacity of the built-in battery is insufficient.
