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 bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.

A front fork comprises a leg including a first tube and a second tube. The first tube has a first end and a second end opposite the first end. The second tube has a third end and a fourth end opposite the third end. The first and second tubes are configured in a telescopic arrangement. The first and second tubes are moveable between a fully extended position and a fully compressed position. The front fork also includes a bumper disposed in the second tube near the fourth end. The bumper is to be contacted during a bottoming-out event. A position of the bumper is adjustable in the second tube.

A controller device usable with a bicycle includes a communication interface configured to receive component data from another controller device of the bicycle. The communication interface is configured to receive auxiliary data from outside the bicycle. The controller device includes a processor in communication with the communication interface. The processor being is configured to determine a location of the bicycle based on the auxiliary data, compare the received component data to a plurality of predetermined component datasets for a plurality of bicycles, respectively, and identify at least one bicycle of the plurality of bicycles based on the comparison and the determined location of the bicycle. The at least one bicycle includes the bicycle. The controller device includes a display in communication with the processor. The display is configured to display a representation for each bicycle of the at least one identified bicycle.

A control device mountable to a handlebar of a bicycle includes a housing, a lever coupled to and pivotable relative to the housing, and a master cylinder portion supported by the housing. The master cylinder portion has a fluid cylinder. The fluid cylinder has a first end and a second end opposite the first end with a cylindrical wall therebetween. An opening extends through the master cylinder portion, from the first end to the second end. The control device also includes a plug removably connected to the master cylinder portion via the opening at the first end of the fluid cylinder, and a piston assembly supported by the housing. The piston assembly is movable relative to the master cylinder portion. The housing is made of a first material, and the master cylinder portion is made of a second material. The second material is different than the first material.

An example front fork for a bicycle disclosed herein includes a crown having a top side and a bottom side opposite the top side. The front fork includes at least one leg coupled to and extending downward from the bottom side of the crown. The front fork also includes a steerer tube coupled to and extending upward from the top side of the crown. The steerer tube includes first and second markings on an outer surface of the steerer tube. The first marking indicates a distance between the first marking and the top side of the crown to enable a user to cut the steering tube to a desired length. The first marking extends in a circumferential direction on the outer surface. The second marking is used to align a stem or handlebars on the steerer tube. The second marking extends in an axial direction and intersects the first marking.

A bicycle derailleur includes a base member mountable to a bicycle frame and a cage assembly moveably coupled to the base member. One or both of a motor and/or electrical generator system may be coupled to and moveable with the cage assembly. The motor is operable to move the cage assembly. The electrical generator system includes a generator and a generator drive system. An energy storage device, spaced apart from the cage assembly, may be connected to the electrical generator system and/or motor with a flexible electrical conductor.

An electric bicycle includes a front wheel, a rear wheel, an electric traction motor which drives the front and/or rear wheel, a traction battery which supplies the electric traction motor with electrical power, a controller for actuating the electric traction motor, a pushing-aid controller for controlling an adaptive pushing-aid function which is assisted by the electric traction motor depending on an interaction force between a person pushing and the electric bicycle, an inclination sensor for determining an inclination angle of the electric bicycle relative to the ground, a traction-motor torque determining device for determining a current traction-motor torque, an electric-bicycle speed sensor for determining a current electric-bicycle speed, and an electric-bicycle weight memory which stores a current electric-bicycle weight value. The interaction force is determined by the pushing-aid controller from the inclination angle, the current traction-motor torque, the current electric-bicycle speed, and the current electric-bicycle weight value.

A control device includes a housing having a base portion and an extension portion. The base portion of the housing has an inward facing side and an outward facing side. The control device includes a lever coupled to and pivotable relative to the housing, and a master cylinder portion supported by the housing. The master cylinder portion has a hollow fluid cylinder. The control device also includes a piston assembly supported by the housing. The piston assembly is movable relative to the master cylinder portion. At least part of the piston assembly is disposed within the master cylinder portion. The master cylinder portion is angled relative to the outward facing side of the base portion of the housing, such that the first end of the fluid cylinder is closer to the outward facing side than the second end of the fluid cylinder is relative to the outward facing side.

A controller device for a bicycle includes a communication interface configured to receive a signal from another controller device. The controller device also includes a sensor including an ultra-wideband radio. In response to the received signal, the sensor is configured to determine a distance between the controller device and the other controller device using the ultra-wideband radio. The controller device also includes a processor in communication with the sensor. The processor is configured to initiate an action of the controller device or an electronic device in communication with the controller device based on the determined distance.
