Abstract
The present invention provides a control device for a human-powered vehicle that can suitably control the transmission. [Solution] A human-powered vehicle includes a transmission configured to change a gear ratio, which is the ratio of the rotational speed of the wheels of the human-powered vehicle to the rotational speed of the crankshaft of the human-powered vehicle, and a drive unit configured to impart propulsion to the human-powered vehicle, wherein the drive unit is configured to change the assist level, and a control device for the human-powered vehicle includes a control unit configured to control the transmission, wherein the control unit is configured to control the transmission to change the gear ratio based on a gear change condition, and when an assist change condition for changing the assist level is met and the gear change condition is met, the control unit is configured to control the transmission in a first control state that suppresses gear changes that increase the gear ratio.
