Claim 0:
1. An electromechanical rear derailleur for coaxial mounting on a rear wheel axis of a bicycle, comprising:
a base member, the base member releasably mounted on a bicycle frame;
a movable member;
a chain guiding arrangement connected to the movable member for rotation about an axis of rotation;
a pivot mechanism connecting the base member to the movable member such that the movable member is movable relative to the base member; and
an electromechanical drive for driving the pivot mechanism,
wherein the base member includes a first connection end and a second connection end, the first connection end for coaxial mounting on the rear wheel axis, and the second connection end for coupling with the pivot mechanism,
a power source having a midplane, in the state mounted on the bicycle frame the midplane lies approximately in a plane with a right dropout,
wherein the electromechanical drive is received in a gear housing, and the gear housing has an electrical interface to directly attach a power source to the gear housing.
