1. A control device for a human-powered vehicle including a motor that applies a propulsion force to the human-powered vehicle and a transmission that shifts a transmission ratio of the human-powered vehicle between a plurality of shift stages, the control device comprising:
an electronic controller configured to control the motor,
the electronic controller being configured to decrease an upper limit value of an output of the motor in an up-shift operation that increases the transmission ratio by shifting from one of the shift stages to another one of the shift stages,
the electronic controller being configured to decrease the upper limit value in a down-shift operation that decreases the transmission ratio by shifting from one of the shift stages to another one of the shift stages, and
the electronic controller being configured to control the motor so that the upper limit value in the up-shift operation performed between two predetermined ones of the shift stages that differ in the transmission ratio by one stage differs from the upper limit value in the down-shift operation performed between the two predetermined ones of the shift stages.
