Claim 35:
36. A control device comprising:
an electronic controller configured to control a transmission device of a human-powered vehicle; and
a storage that stores a designated transmission ratio in an updatable manner, the designated transmission ratio being a transmission ratio to which the transmission device is controlled by the electronic controller as a crank of the human-powered vehicle is rotated so that the transmission device is set to the designated transmission ratio as the human-powered vehicle is started into motion from a stopped state,
the electronic controller being further configured to
acquire reference information,
determine, based on the reference information, whether to maintain the designated transmission ratio or update the designated transmission ratio to be used a next time the vehicle is started,
execute a control to maintain or update the designated transmission ratio, and
control the transmission device as the crank of the human-powered vehicle rotates when the human-powered vehicle is started so that the transmission ratio at which the vehicle is started is equal to the designated transmission ratio,

the reference information excluding information related to a gradient of a road surface, information related to manual operation of the transmission device, and information related to propulsion assistance of the human-powered vehicle.
