An electrically assisted bicycle includes a crank shaft, pedals, an electric motor, a pedal effort sensor that detects a pedal effort exerted on the pedals, a propelling detection sensor that detects that the electrically assisted bicycle is starting to be propelled, and a controller that executes a first control in which a command value provided to the electric motor is obtained based on the output of the pedal effort sensor and a second control in which a command value provided to the electric motor is obtained based on the output of the pedal effort sensor and the output of the propelling detection sensor. The controller is configured or programmed to select the first control or the second control as a calculation method of a command value provided to the electric motor during a period of time from a state in which the electrically assisted bicycle is stopped until a detection of the rotation of the crank shaft.
