A bicycle derailleur includes a base member mountable to a bicycle frame and having first and second laterally spaced mounting portions defining first and second planes, and a space therebetween dimensioned to receive a portion of the bicycle frame. A first mounting arrangement defines a first pivot axis oriented at an acute angle relative to the first and second planes. A second mounting arrangement defines a second pivot axis parallel to the first pivot axis. A first link is pivotally connected to the first mounting arrangement and a second link is pivotally connected to the second mounting arrangement. A moveable member is pivotally connected to the first and second links. A battery may be mounted on the base member and electrically connected with a motor carried by the moveable member.

An electronic component for a bicycle includes a communication interface and a processor in communication with the communication interface. The processor is configured to identify a first power on time. The first power on time identifies a time at which the electronic component was powered on by a power source of the bicycle. The processor is configured to listen for one or more messages after the electronic component is powered on and receive, via the communication interface, a message of the one or more messages. The received message is from another electronic component of the bicycle and identifies a second power on time. The second power on time is for the other electronic component. The processor is configured to compare the second power on time to the first power on time and initiate, based on the comparison, pairing of the other electronic component with the electronic component.

A position detection device for a bicycle may include a bicycle component defining an interior and an exterior. A detectable element may be disposed in the interior of the bicycle component and movable relative to the bicycle component. At least one detecting element is disposed in the exterior of the bicycle component, the at least one detecting element operable to detect: a first position of the detectable element relative to the bicycle component, and a second position of the detectable element relative to the bicycle component, wherein the second position is different from the first position.

A rear derailleur includes a base member mountable to a bicycle frame, a movable member movably coupled to the base member, and a pivot member rotatably coupled to the movable member. The rear derailleur also includes a chain guide assembly rotatably connected to the movable member via the pivot member. The rear derailleur includes a damper device disposed within the movable member. The damper device is operable to apply a damping force to the chain guide assembly when the chain guide assembly rotates. The damper device includes a friction member having a friction surface. A first portion of the friction surface is in frictional engagement with the pivot member, and a second portion of the friction surface is in frictional engagement with the movable member. The friction device is disposed within the movable member at a distance relative to the biasing device in an axial direction along the pivot member.

A system for an electric bicycle (50) includes an energy storage device (102). The energy storage device (102) includes a housing that is mountable to a frame (52) of the electric bicycle (50), battery cells disposed within the housing, and output power terminals supported by the housing and electrically connectable to the battery cells. The energy storage device (102) includes a processor and a first wireless communication device. The system includes a human/machine interface (HMI) electrically connected to the energy storage device (102) via the output power terminals. The HMI includes a second wireless communication device. The processor is configured to change a mode of the energy storage device (102) based on a signal received by the first wireless communication device from the second wireless communication device.

A system for a bicycle (100) includes a plurality of controller devices (120, 122). A type of controller device (120, 122) is the same for two or more controller devices (120, 122) of the plurality of controller devices (120, 122). The system includes a pairing coordinator device (124) configured to receive a respective device type identification from each controller device (120, 122), and identify the type of controller device (120, 122) for the two or more controller devices (120, 122) based on the received device type identifications for the two or more controller devices (120, 122). Based on the identification of the type of controller device (120, 122), the pairing coordinator device (124) is configured to update the device type identifications for the two or more controller devices (120, 122), respectively, such that the updated device type identifications are different than each other. The pairing coordinator device (124) is configured to pair only controller devices (120, 122) of the plurality of controller devices (120, 122) having different respective device type identifications with the pairing coordinator device (124).

Die Erfindung bezieht sich auf eine Elektrofahrrad-Mittelmotor-Antriebseinheit (40) mit einem Antriebsgehäuse (46), einer das Antriebsgehäuse (46) in Querrichtung durchdringenden Tretlagerwelle (50) und einer hierzu parallelen Abtriebswelle (52),wobei dem Antriebsgehäuse (46) an mindestens einer Lateralseite der Antriebseinheit (40) und koaxial zu der Tretlager-Axialen (50') ein im Wesentlichen kreisringförmiger Radialklemmring (621,622) zugeordnet ist, undwobei der Radialklemmring (621,622) eine zirkuläre Außen-Klemmfläche (64) aufweist.

Front forks for bicycles are described herein. An example front fork (200) includes a leg (204, 206) including an upper tube (210, 212) and a lower tube (214, 216). The upper tube (210, 212, 120, 2310) and the lower tube (214, 216) are configured in a telescopic arrangement. The upper tube (210, 212) and the lower tube (214, 216) define an interior region (312, 326) that is sealed and contains a volume of air in the lower tube (214, 216). The front fork (200) also includes a valve (384, 386) coupled to the upper tube (210, 212) at or near a top end of the upper tube (210, 212). A flow path is formed between the volume of air in the lower tube (214, 216) and the valve (384, 386) such that when the valve (384, 386) is opened, pressure in the lower tube (214, 216) is equalized with atmospheric pressure.
