Claim 13:
14. A control device for a human-powered vehicle, the control device comprising:
an electronic controller configured to control a transmission that shifts a ratio of a rotational speed of a wheel of the human-powered vehicle to a rotational speed of a crank axle of the human-powered vehicle in accordance with a control state, wherein:
the electronic controller is configured to select the control state from either one of a first control state and a second control state;
the electronic controller is configured to control the transmission so that the transmission shifts the ratio in accordance with a shifting condition and an input from a shift operation device that is operable by a user;
in a case where the electronic controller controls the transmission so as to shift the ratio in accordance with an input from the shift operation device in the first control state, the electronic controller is configured to switch the control state from the first control state to the second control state;
in at least one of a case where a vehicle speed accelerates and exceeds a first vehicle speed and a case where the vehicle speed decelerates and becomes less than a second vehicle speed in the second control state, the electronic controller is configured to switch the control state from the second control state to the first control state; and
shifting of the ratio in accordance with the shifting condition is more restricted in the second control state than the first control state.
