PROBLEM TO BE SOLVED: To inhibit generation of vibrations of a motor during regenerative braking.SOLUTION: A bicycle with an electric motor includes: a motor for generating an auxiliary driving force; regenerative means for generating a braking force with magnitude appropriate to a current value of a regenerative current by recovering the regenerative current from the motor; vibration detection means for detecting motor vibrations associated with the recovery of the regenerative current from the motor; and control means for limiting the current value of the regenerative current to a value lower than a maximum value capable of being recovered from the motor if motor vibrations are detected by vibration detection means.SELECTED DRAWING: Figure 5
