Abstract: A bicycle suspension control apparatus includes a user operating device and a controller. The controller is operatively coupled to the user operating device to selectively control a pair of bicycle suspensions between a plurality of operating states. The controller selectively changes the operating states of both of the suspensions to different ones of the operating states in response to a single operation of the user operating device. The controller includes a receiving part, a storage part and a control part. The receiving part receives combination information indicating at least one combination of the operating states from among combinations of the operating states of the suspensions. The storage part stores the combination information received by the receiving part. The control part controls the suspensions based on the combination information stored in the storage part when the user operating device is operated.
