1. A control device for a human-powered vehicle, the control device comprising:
an electronic controller configured to control a motor configured to apply an assist force to the human-powered vehicle, the electronic controller controlling the motor so as to change a ratio of the assist force produced by the motor to a human driving force in accordance with the human driving force; and
a data storage,
the electronic controller being configured to control the motor so that the assist force produced by the motor becomes smaller than a maximum value upon determining that the human driving force is smaller than a first predetermined value, and to control the motor so that the assist force produced by the motor is prevented from exceeding the maximum value upon determining that the human driving force is equal or larger than the first predetermined value, the ratio decreasing as the human driving force increases beyond the first predetermined value,
the data storage being configured to store information related to the first predetermined value in a changeable manner, and
the electronic controller being configured to communicate with an operation unit or an external device and to change the first predetermined value in response to a signal received from the operation unit or the external device.
