A bicycle rear derailleur including a base member, a chain guide, an actuator, and a controller. The chain guide is movably coupled to the base member. The actuator is operatively coupled to the chain guide to move the chain guide relative to the base member. The controller is electrically connected to the actuator to move the chain guide relative to the base member from a current stop position to a target-stop position. The controller is configured to change a current rear shift position corresponding to the current stop position based on a front shift position of a front derailleur.
