Abstract: A bicycle control system is provided that is configured to control a bicycle component using a threshold value that is appropriate for the rider. The bicycle control system includes a controller for controlling a bicycle component based on a threshold value and a parameter related to a running state of a bicycle. The controller changes the threshold value when an operating unit is operated, and the change amount of the threshold value when the operating unit is operated is determined based on an operating state of the operating unit.

Abstract: A bicycle transmission system comprises a first input device, a transmission, an assist device, and a controller. The first input device is configured to receive a first input operation from a user. The transmission is configured to transmit a pedaling torque to a wheel at a current gear ratio among a plurality of gear ratios. The assist device is configured to assist a rotation of the wheel at a current assist ratio among a plurality of assist ratios. The controller is configured to change the current gear ratio into a predetermined gear ratio without changing the current assist ratio based on the first input operation in a first condition. The controller is configured to change the current gear ratio into a predetermined gear ratio and change the current assist ratio into a predetermined assist ratio based on the first input operation in a second condition.
