1. A control device for a human-powered vehicle including a crank axle, a first rotational body connected to the crank axle, a wheel, a second rotational body connected to the wheel, a transmission body engaged with the first rotational body and the second rotational body to transmit 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 of a rotational speed of the wheel to a rotational speed of the crank axle, an electric actuator configured to actuate the derailleur, and a motor configured to drive the transmission body, the control device comprising:
an electronic controller including a processor, the electronic controller being communicably connected to the electric actuator and the motor and configured to control the motor and the electric actuator,
the electronic controller being 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, and
the electronic controller being 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.
