Abstract: An electric device of a human-powered vehicle comprises electronic controller circuitry. The electronic controller circuitry is configured to obtain at least one of chain guide information and sprocket information. The chain guide information is indicative of at least one chain guide. The sprocket information is indicative of at least one sprocket assembly. The electronic controller circuitry is configured to set one of at least two pieces of gear changing information as setting information based on the at least one of the chain guide information and the sprocket information. The electronic controller circuitry is configured to perform a gear shift control based on the setting information. Each of the at least two pieces of the gear changing information including at least two stop positions of a chain guide respectively corresponding to at least two sprockets of a sprocket assembly.

Abstract: A derailleur for a human-powered vehicle comprises a base member, a movable member, a linkage, an electrical actuator, a first biasing member, and a second biasing member. The base member is configured to be attached to a vehicle body of the human-powered vehicle. The movable member is configured to be movable relative to the base member in a first direction and a second direction different from the first direction. The linkage is configured to movably connect the movable member to the base member. The electrical actuator is configured to operatively move the movable member relative to the base member. The first biasing member is configured to deform if first external force is applied to move the movable member in the first direction. The second biasing member is configured to deform if second external force is applied to move the movable member in the second direction.

Abstract: A user interface of a bicycle derailleur is configured to receive a user input to execute at least one of: calibration in which a sensor is reset; changing an assist operation of an assist driving unit; changing information displayed in a display; a recovering operation by an actuator of the bicycle derailleur; a reset of a pairing operation; changing a shifting threshold used in an automatic shifting mode; changing a communication channel between a wired communication channel and a wireless communication channel; changing a function assigned to an operating device; a shut-down of a system of the bicycle derailleur; a wake-up operation of the system; a restart of the system; an operation of at least one additional bicycle component; changing a shifting mode between the automatic shifting mode and a manual shifting mode; and changing the shifting operation between a synchronized shifting mode and a non-synchronized shifting mode.
