Abstract: An electrical bicycle derailleur includes a base member and a movable member movably arranged between a retracted position and an extended position. A linkage operatively couples the movable member to the base member. The linkage includes a first link member and a second link member. The first link member is disposed closer to the base member than the second link member. A motor unit is operatively coupled to the first and second link members to rotate the first and second link members. A linkage housing is configured to support the first and second link members and the motor unit. A first diameter of the first link member is different from a second diameter of the second link member and/or a first tooth number of the first link member is different from a second tooth number of the second link member.
