A bicycle rear derailleur, adapted to be mounted on a bicycle frame, comprises a mounting frame assembly, a linkage assembly and a movable assembly. The mounting frame assembly comprises a pivot, a main frame, a resistance applying member and a resistance controller. The pivot is adapted to be fixed on the bicycle frame. The main frame is rotatably disposed on the pivot. The resistance-applying member is disposed on the main frame, and the resistance-applying member is configured to apply a force on the pivot so as to adjust a rotational resistance of the main frame. The resistance controller is disposed on the main frame, and the resistance controller is configured to control the resistance-applying member to adjust the force applied on the pivot. The linkage assembly is pivoted to the mounting frame assembly. The movable assembly is pivoted to the linkage assembly.
