A control device including an electronic controller for controlling a human-powered vehicle. The electronic controller is configured to control an adjusting device that is configured to adjust a seat height of the human-powered vehicle upon determining the human-powered vehicle is being stopped while traveling uphill.

A human-powered vehicle includes a crank axle, a first rotational body, a wheel, a second rotational body, a transmission body that transmits a driving force between the first rotational body and the second rotational body, a derailleur configured to operate the transmission body to change a transmission ratio, an electric actuator configured to actuate the derailleur, and a motor configured to drive the transmission body. A control device has an electronic controller configured to control the motor and drive the transmission body upon determining the derailleur has been actuated with the electric actuator to change the transmission ratio and a predetermined condition related to pedaling is satisfied. The electronic controller is configured to control the electric actuator so as not to change the transmission ratio until a first condition related to shifting is satisfied in a case where the derailleur is actuated.

A control device includes an electronic controller that controls a motor of a human-powered vehicle. The electronic controller outputs a signal to change a transmission ratio by operating a linking body with a derailleur while driving the linking body with the motor where a first condition related to pedaling is satisfied.
