Abstract: A bicycle derailleur comprises a base member, a movable member, a motor unit, and a controller. The controller is configured to control the motor unit to rotate an output shaft of the motor unit at a first maximum voltage during a first shifting operation of the chain in a first shifting direction. The controller is configured to control the motor unit to rotate the output shaft of the motor unit at a second maximum voltage during a second shifting operation of the chain in a second shifting direction. The first maximum voltage is different from the second maximum voltage. The bicycle derailleur is configured to receive electricity from an electric power source configured to supply electricity to an assist driving unit.

Abstract: A bicycle component is basically provided with a communicator and a controller. The communicator is configured to wirelessly receive a pairing trigger signal generated in response to a user trigger input of a trigger input device, and to wirelessly receive a first pairing demand signal generated in response to a first user input of a first input device. The controller is configured to cause the bicycle component to enter a pairing mode in response to the pairing trigger signal being received by the communicator. The controller is configured to establish wireless communication between the bicycle component and a first remote component that sent the first pairing demand signal in a state where the bicycle component is in the pairing mode.

Abstract: A bicycle operating device is basically provided with a base member, a first operating member and an attachment. The base member has an interior space that is configured to receive an operating unit. The first operating member is configured to move along a first operating path from a rest position to an operated position to operate the operating unit when the operating unit is disposed in the interior space. The attachment blocks the first operating path to prevent movement of the first operating member from reaching the operated position.

Abstract: A derailleur comprises a base member, a movable member, a linkage structure, a pulley assembly, and a rotational force control structure configured to control rotational force of the pulley assembly relative to the movable member. The pulley assembly is pivotally movable relative to the movable member about a pivot axis in first and second directions. The pulley assembly is configured to move in the first direction upon moving from a second pivotal position toward a first pivotal position. The rotational force control structure includes a cam member having a first cam surface, an abutment member configured to abut the first cam surface, and a biasing member configured to bias the abutment member. The abutment member is configured to abut the first cam surface by the biasing member to apply first additional force to the pulley assembly in the first direction while the pulley assembly is in the first pivotal position.

Abstract: An electric front derailleur is basically provided with a base, a chain guide, a linkage and an electric motor unit. The base is configured to be mounted to a bicycle. The chain guide is configured to guide a chain. The linkage movably couples the chain guide to the base in a forward-rearward direction to move the chain guide between a retracted position and an extended position in a mounted state where the base is mounted to the bicycle. The electric motor unit is supported on the base and operatively coupled to the linkage to move the chain guide between the retracted position and the extended position. The electric motor unit is arranged at least partly closer to the bicycle than the chain guide.
