A bicycle operating apparatus for wirelessly controlling at least one component of a bicycle includes a carrier element on a fastening device for fixing the bicycle operating apparatus to a handlebar of the bicycle, a housing attachable to the carrier element having an energy storage compartment for receiving an energy storage element and having an electronic circuit arrangement in the housing. At least one switch is connected to the electronic circuit arrangement on the housing. An operating component mounted on the carrier element to be pivotable about an operating axis preloaded into a neutral position which is able to be deflected out of the neutral position in a first direction of rotation about the operating axis in order to actuate the switch, and the operating axis extends obliquely with respect to the flat outer surface.

Bicycle operating apparatus

A control device for a bicycle is arranged or can be arranged on the handlebar of the bicycle and serves to wirelessly drive at least one electronic, electrical, electromechanical or electrohydraulic component of the bicycle. The control device includes an operator control arrangement which has at least one manually operable operator control element and is designed to respond to operation of the operator control element and to output electrical signals which represent the operation. The control device also includes at least one electronic circuit arrangement comprising a radio communication circuit and a control circuit which is connected or can be connected to the operator control arrangement. The control device also may include at least one antenna which is connected or can be connected to the radio communication circuit or which is integrated into the said communication circuit.

Control device for wirelessly controlling at least one component of a bicycle

An operating device for operating an electrical bicycle component includes a base element, an actuating element and a housing. The base element is configured to be non-rotatably mounted about a bicycle handlebar. The actuating element is rotatable relative to the base element from a neutral position to a first actuating position. The actuating element may be pre-loaded into the neutral position. A first electrical contact switch may be actuated when the actuating element is moved from the neutral position to the first actuating position.

Operating device for operating an electrical bicycle component

An operating device for operating an electrical bicycle component includes an annular base element, annular actuating element and first electrical contact switch. The annular base element is configured to be non-rotatably mounted about a bicycle handlebar. The annular actuating element is rotatable relative to the annular base element from a neutral position to a first actuating position. The annular actuating element is pre-loaded into the neutral position. The first electrical contact switch is actuated when the annular actuating element is moved from the neutral position to the first actuating position to generate a first sensory feedback.

The invention relates to a drive pawl within a bicycle transmission, wherein at least one torque transmission path extends from an input side to an output side across the same, and that has allocated thereto, relative to a first component supporting said pawl, a rotatable ring part, which interacts with the pawl for the alternate activation and deactivation of the pawl.

Bicycle transmission, particularly in form of a multi-speed gear hub

A multi-speed hub for cantilever mounting to a bicycle frame generally includes a planetary gear mechanism, a hub shaft, a hub shell, a spoke shell, a driver and a driven gear. The hub shell is cantilever-mounted to the bicycle frame and configured to enclose the planetary gear mechanism and the hub shaft. The spoke shell, driver and driven gear are rotatably supported by the hub shell. One end of the hub shaft is indirectly supported by the hub shell and the other end of the hub shaft is fixed to the bicycle frame.
