Controller for electric bicycle, power unit for electric bicycle, and electric bicycle

A controller for an electric bicycle includes a pedal torque-dependent power supply part 113 that supplies pedal torque-dependent power, which is changed in response to the change of a signal output from a pedal torque detecting part detecting torque input to pedals, an acceleration power supply part 12 that supplies acceleration power before the time at which the maximum peak is formed in a signal output from the pedal torque detecting part while pedals make one rotation after torque is input to the pedals, and a moderate power supply part 112 that supplies moderation power before the time at which the maximum peak is formed in the signal output from the pedal torque detecting part while the pedals make one rotation torque is input to the pedals, and after the time at which the acceleration power is supplied.
