A coordinator device for a bicycle includes a processor configured to receive a signal generated in response to user input at an input element from a controller device. The signal includes data identifying a device type and data identifying the input element. The coordinator device includes a memory configured to store the data identifying the device type and the data identifying the input element. The processor is configured to generate a notification based on the received signal, transmit the generated notification to the mobile device, and in response to the transmission of the generated notification, receive a request for data related to the received signal from the mobile device. The processor is further configured, in response to the request, to transmit the stored data to the mobile device, such that an association of the controller device with the representation of the controller device is identifiable within the GUI at the mobile device.

Controller indication

An integrated bicycle control device has a handlebar portion of a bicycle handlebar assembly. The handlebar portion has a body with a gripping portion adjacent a distal end of the body and a transition portion spaced from the gripping portion. A compartment may be formed in the transition portion and an opening in the body may permit access to the compartment. An actuator is disposed near the distal end of the gripping portion. A control element and/or other elements or circuitry may be disposed within the compartment. The control device may include integrated accessory attachment structure.

Integrated bicycle control device

A bicycle rear derailleur or gear changer may include a mounting portion mountable to a bicycle frame, an electrical portion attached to the mounting portion and including power supply alignment and attachment features, and an electrical cable electrically connected to the electrical portion and electrically connectable to a printed circuit board (PCB) of a movable member movably coupleable to the mounting portion. The mounting portion and the electrical portion may be formed of different materials.

Bicycle rear derailleur

A grip cover for a bicycle control device includes a high durometer portion that is configured to engage the bicycle control device to maintain the grip cover in contact with the bicycle control device. The grip cover further includes a low durometer portion that is connected to the high durometer portion.

Grip cover

A bicycle rear derailleur includes a base member having a first portion and a second portion. The first portion of the base member is mountable to a bicycle frame, and the second portion of the base member is attached to the first portion of the base member and includes at least a portion of a power supply attachment. The bicycle rear derailleur also includes a movable member movably coupled to the first portion of the base member and electrically connected to the second portion of the base member. The bicycle rear derailleur includes a chain guide assembly rotatably connected to the movable member.

An integrated bicycle control device has a handlebar portion of a bicycle handlebar assembly. The handlebar portion has a body with a gripping portion adjacent a distal end of the body and a transition portion spaced from the gripping portion. A compartment may be formed in the transition portion and an opening in the body may permit access to the compartment. An actuator is disposed near the distal end of the gripping portion. A control element and/or other elements or circuitry may be disposed within the compartment.

A control device may be configured so as to be integrated, or coupled, with a bicycle to control bicycle components. The control device may also be integrated with other control devices and system components to control bicycle components. The control device may interface with electromechanically controlled bicycle components so as to trigger an action when actuated. The control device may be dimensioned so as to have a mating surface contoured to matingly engage with a mounting surface of a bicycle, such as on a handlebar. The control, device may also be dimensioned so as to have a compact and/or concealed appearance aided by a low profile relative to the bicycle mounting surface selected for the control device. The control device may be configured such that the control device is protected from actuation from unintended or other user inputs.

Bicycle electrical control device and system

A grip cover for a bicycle control device includes a high durometer portion that is configured to engage the bicycle control device to maintain the grip cover in contact with the bicycle control device. The grip cover further includes a low durometer portion that is connected to the high durometer portion. The low durometer portion is configured to be tensioned by the high durometer portion when the grip cover is installed on the bicycle control device.

A hydraulic brake mechanism is mountable to a bicycle handlebar. The hydraulic brake mechanism includes a housing having a base portion and an extension portion, the base portion including first and second ends, the base portion including a handlebar clamp at the first end, the base portion extending generally horizontally and the extension portion extending forwardly of the base portion at the second end and angled generally upwardly from the base portion when the hydraulic brake mechanism is mounted to the bicycle handlebar, the housing sized and shaped to be grasped by a user's hand, the housing having a fluid outlet port in the extension portion. The hydraulic brake mechanism may include a fluid line attached to the fluid outlet port and disposed in a groove formed along a length of the extension portion and the base portion of the housing.

Hydraulic brake mechanism

A hydraulic brake mechanism is described including a housing. A master cylinder assembly is disposed within the housing, and the master cylinder assembly includes a fluid chamber. The fluid chamber includes a first chamber portion having a first diameter and a second chamber portion having a second diameter, with the first diameter greater than the second diameter. The fluid chamber includes a transition region between the first and second chamber portions. The mechanism includes a piston assembly having a piston disposed within the fluid chamber. A first seal is configured to sealingly engage between the first chamber portion and the piston, and a second seal is configured to sealingly engage between the second chamber portion and the piston. The mechanism includes an outlet port extending from the fluid chamber from or adjacent the transition region.

A mounting device is shown for mounting components to a bicycle handlebar having a handlebar axis. The mounting device includes a mounting bracket mountable to the handlebar about the handlebar axis. The mounting bracket includes a first clamp portion and a second clamp portion hingedly connected to the first clamp portion to interiorly receive the handlebar. An interior channel is defined by spaced sidewalls and formed in a portion of the circumferential length of one of the first and second clamp portions, and a hole is formed through the clamp portion and opens to the channel.

Bicycle suspension system

A mounting device for mounting first and second bicycle control components to a bicycle handlebar having a handlebar axis. The mounting device generally includes first and second mounting brackets. The first mounting bracket is adjustably mounted to the handlebar about the handlebar axis. One of the first and second bicycle control components is attached to the first mounting bracket. The second mounting bracket is adjustably attached to the first mounting bracket. The other of the first and second bicycle control components is attached to the second mounting bracket. The second mounting bracket is displaced between alternative attachment positions on the first mounting bracket. The first mounting bracket is rotated between alternative mounting positions on the handlebar.
