Abstract
A human-powered vehicle control device includes an electronic controller that controls a transmission device to shift a ratio of a rotational speed of a wheel to a rotational speed of a crank axle. The controller controls the transmission device between first, second, and third control states. The controller controls the transmission device in the first control state for a predetermined period in a case where the human-powered vehicle starts to travel until a vehicle state becomes a predetermined state. The controller switches from the first to the second control state if the vehicle state becomes the predetermined state. The controller switches from the first to the third control state if a human driving force input to the human-powered vehicle becomes greater than a predetermined driving force during the predetermined period. Shifting of the ratio is more restricted in the first control state than the second and third control states.
