Abstract
The disclosure describes an electromechanical rear derailleur for coaxial mounting on a rear wheel axis. The rear derailleur has a base member, a pivot mechanism, a movable member having a chain guiding arrangement, and an electromechanical drive for driving the pivot mechanism. The pivot mechanism connects the base member to the movable member. The chain guiding arrangement is connected to the movable member for rotation about an axis of rotation. The base member comprises a first connection end, which can be mounted coaxially with the rear wheel axis, and a second connection end for coupling with the pivot mechanism.

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;
- an electromechanical drive for driving the pivot mechanism, the electromechanical drive received in a gear housing;
- and
- a power source located within the base member, the power source being a battery attached to a top side of the gear housing,
- 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.
