Abstract

An electrically assisted bicycle includes a motor controller that calculates a command value which determines a magnitude of an assisting torque based on at least an output of a pedal torque detector. The motor controller switches between a first control and a second control, in which a time required for the assisting torque to change to meet a change in the pedal torque is shorter and the amount of change in the assisting torque to meet a change in the pedal torque is greater than in the first control.
