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.

Electromechanical derailleur

An e-bike interface is a hybrid wired/wireless e-bike control system that integrates wireless bicycle components into operation of an e-bike. The e-bike interface provides a frame-mounted control and display that is wired to, for example, an assist motor and a battery, and provides a wireless communication bridge between wireless bicycle components and corresponding wireless controls located on a handlebar.

Interface for electric assist bicycle

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.

Controlling automatic gear-changing of an electric gear-change apparatus of a bicycle, the method may involve assigning each of a plurality of gears of the bicycle a predetermined gearing range. Controlling the process may also involve assigning a predetermined lower limit value and a predetermined upper limit value to each gearing range, wherein the upper limit value of a gearing range is in each case larger by a predetermined value than the lower limit value of a next higher gearing range, and the upper limit value of the gearing range and the lower limit value of the next higher gearing range define between them an overlap range. Controlling the process may also involve selecting an engagement of either a gear or a next higher gear in the overlap range depending on a speed profile of the bicycle.
