1. An electromechanical rear derailleur for a bicycle, comprising:
- a base member attachable to the bicycle along a mounting axis;
a movable member having a cage assembly attached thereto;
a linkage including pivot axes oriented substantially perpendicular to the mounting axis, the linkage coupling the movable member to the base member and operative to enable movement of the movable member relative to the base member;
a power source disposed on the rear derailleur rearward of the pivot axes;
a motor electrically connected to the power source; and
a transmission coupled to and actuated by the motor to move the movable member.

Abstract
An electromechanical rear derailleur is provided for a bicycle, including a base member for attachment to the bicycle along a mounting axis. A movable member has a cage assembly attached thereto. A linkage is provided including pivot axes oriented substantially perpendicular to the mounting axis, the linkage coupling the movable member to the base member and operative to enable movement of the movable member relative to the base member in a direction substantially parallel to the mounting axis. A power source powers an electric motor connected thereto and a transmission is coupled to and actuated by the motor to move the movable member.
