A battery-assisted bicycle less prone to abrupt change in assist force as the assist by the electric motor is stopped while the battery-assisted bicycle moves by the assist with no pedal effort. The battery-assisted bicycle (1) includes an electric motor (61), a vehicle speed calculator (152) that calculates a vehicle speed of the battery-assisted bicycle (1), a first state determiner (150) that determines whether a first state is attained, an operation unit (190) capable of outputting a stop signal used to give instruction to stop the electric motor (61), a timing unit (157) that measures time from when a stop signal is input, and a motor controller (105) that controls driving of the electric motor (61) so that the vehicle speed attained when the time elapsed from the point of input of the stop signal reaches a prescribed first period is a first vehicle speed and stops the electric motor (61) after the first period, if the first state determiner (150) determines that the battery-assisted bicycle (1) is in the first state and the stop signal is input from the operation unit (190).
