(54)ELECTRICALLY ASSISTED BICYCLE


(57) There is provided an electrically assisted bicycle 1 having a motor control module 95 which calculates a command value which determines on the magnitude of assisting torque based on at least an output of the pedal torque detection unit 57. The motor control module 95 is configured so as to do the switching 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.
