1. A control device configured to control a transmission of a human-powered vehicle, the control device comprising:
an electronic controller configured to control the transmission,
the electronic controller being configured to actuate the transmission to shift a transmission ratio based on at least one shifting condition, and
the electronic controller being configured to hold the at least one shifting condition that is associated with riding-related information of the human-powered vehicle upon determining the human-powered vehicle is in a riding convergence state, the riding convergence state is a state in which the cadence is substantially constant, the electronic controller being configured to hold the at least one shifting condition by accessing the at least one shifting condition in a storage that stores the at least one shifting condition, after holding the at least one shifting condition, the electronic controller being further configured to determine the at least one shifting condition to perform a shifting operation when the human-powered vehicle is in the riding convergence state, the riding-related information includes at least a cadence of the human-powered vehicle, the electronic controller increasing a threshold value of the shifting, condition if the riding-related information takes a value corresponding to a momentum that is greater than a first converging threshold value, the momentum being applied to a crank of the human-powered vehicle.
