Abstract: A method for controlling electronic shifting of a bicycle includes identifying, by a processor, a gear shift command. The processor adjusts a cadence band based on the identified gear shift command. The cadence band includes an upper cadence limit and a lower cadence limit. Adjusting the cadence band includes increasing the upper cadence limit, decreasing the lower cadence limit, or increasing the upper cadence limit and decreasing the lower cadence limit. The electronic shifting of the bicycle is controlled based on the adjusted cadence band.

Abstract: 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.

Abstract: An electronic control device may be configured to be integrated, or coupled, with a bicycle to control bicycle components. The electronic control device may wirelessly control bicycle components to trigger an action when actuated. The electronic control device may be dimensioned to have a mating surface contoured to matingly engage with a mounting surface of a bicycle, such as on a handlebar. The electronic control device may also be dimensioned to have a compact and/or concealed appearance aided by a low profile relative to the bicycle mounting surface selected for the control device.

Abstract: An electronic component for a bicycle includes a processor configured to receive data from a sensor, determine a first speed and a second speed of the bicycle based on a subset of the received data, and determine an acceleration of the bicycle based on the determined first speed and the determined second speed of the bicycle. The processor is further configured to compare the determined acceleration of the bicycle to a predetermined threshold acceleration, and control the bicycle based on the comparison.

Abstract: A bicycle front shifting system includes operable to transmit a wireless signal, a crank assembly with two crank arms and a pedal on each of the two crank arms. The crank assembly is rotatable about a rotation axis. A front shift unit is coupled to the crank assembly and is rotatable about the rotation axis. The front shift unit includes a chain ring component with a big chain ring and a small chain ring. The small chain ring has a small diameter and the big chain ring has a big diameter that is larger than the small diameter. A shift mechanism is coupled to and rotatable with the chain ring component about the rotation axis. The shift mechanism is configured to receive the wireless signal from the shifter and to shift a chain between the big chain ring and the small chain ring according to the wireless signal.

Abstract: 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.

Abstract: A method for controlling electronic shifting of a bicycle includes identifying, by a processor, sensor data. The sensor data identifies a state of the bicycle. The processor determines a rider engagement status based on the identified sensor data. The processor determines a target cadence based on the determined rider engagement status. The processor determines a cadence band based on the determined target cadence. The electronic shifting of the bicycle is controlled based on the determined cadence band. The controlling of the electronic shifting of the bicycle includes actuating a motor of the bicycle for electronic shifting of the bicycle when a cadence of the bicycle is outside of the determined cadence band.
