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.

Electromechanical rear derailleur for coaxial mounting

A rear derailleur is configured as a hierarchical, at least two-level modular construction system and comprises at least several of the modules: “base element module”, “swivel formation module”, “shifting element module”, and “chain guiding device module”. At least one of the modules is replaceable and handleable in one piece. At least one of the modules includes at least one sub-assembly that is replaceable and handleable in one piece. In an embodiment the modular construction system is configured to use at least one family of sub-assemblies comprising at least two family members within at least one of the modules. Detachable connection interfaces of the family members to adjacent sub-assemblies of the module within the sub-assembly family are configured uniformly across family members for the respective sub-assembly family in such a way that a family member of the sub-assembly family of the module is exchangeable for another family member of the same sub-assembly family that, is for example, of different material, of different design, of different functionality or has different surface properties, while retaining the remaining sub-assemblies of the module.

Modular bicycle derailleur

The invention relates to an electromechanical derailleur for mounting on a rear wheel axis. The derailleur has a stationary element, a pivoting mechanism, a movable element having a chain guide arrangement, and a gearing housing. The gearing housing receives an electromechanical drive for driving the pivoting mechanism. The stationary element defines a housing void in which the gearing housing is disposed, and has a fastener for a power source. The power source is fastened to the stationary element such that said power source is electrically connected to the electromechanical drive in the gearing housing.

Electromechanical derailleur

An Actuating device for a bicycle is provided. The actuating device may include a static element which is positionally fixed in relation to a bicycle frame, a movable element which is movable in relation to the static element, an electromechanical drive which provides drive force for a movement of the movable element. The electromechanical drive has a motor and a gearing driven by the motor. The gearing may include a first gearing wheel and a second gearing wheel which is in engagement with the first gearing wheel.
