PROBLEM TO BE SOLVED: To provide a control device for a bicycle which controls a drive unit for generating auxiliary power and an electrically-driven transmission unit, and in which a parameter related to rotation of a crank shaft and man power drive force are made difficult to vary.SOLUTION: A control device 1 for a bicycle controls a drive unit 2 for generating auxiliary power, and an electrically-driven transmission unit 107b. The control device 1 for the bicycle includes: a sensor 50 for detecting a tread force which is a man power drive force; a rotational speed sensor 8; and a control unit 4. The rotational speed sensor 8 detects a crank rotation speed which is a parameter related to a rotation of a crank shaft 102. The control unit 4 controls at least either one of the drive unit 2 and the electrically-driven transmission unit 107b such that crank torque and the crank rotation speed is within a predetermined range. |
