摘要： 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.

摘要： 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.

摘要： 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.

摘要： The disclosure provides a bicycle front derailleur including a fixed component, a chain guide, a first link, a second link, and a driving assembly. Two opposite ends of the first link are respectively disposed on the fixed component and the chain guide. The two opposite ends of the second link are respectively disposed on the fixed component and the chain guide. The driving assembly includes a driving shaft, a push component, an output gear and a power source. The push component and the output gear are fixed on the driving shaft, the power source is disposed on the fixed component and connected to the output gear, the push component is in contact with the first link, and the power source is configured to drive the push component to pivot the first link with respect to the fixed component via the output gear and the driving shaft.
