摘要： A detector for a bicycle that includes a magnet, which generates a generated magnetic field, and a magnetic field sensor. The mutual position of the magnet and of the sensor is fixed, and the sensor is immersed in the generated magnetic field. A length of a path intended for a non-diamagnetic movable element is immersed in the generated magnetic field; if in said path length there is at least one actual portion of the movable element, the sensor detects the magnetic field perturbed by the actual portion of the movable element. Bicycle equipment and a bicycle derailleur are also described.

摘要： A bicycle shifting apparatus comprises a shifting controller. The shifting controller is configured to control one of a front shifting device and a rear shifting device to change one of a front shift position and a rear shift position in response to a user input. The shifting controller is configured to control the other of the front shifting device and the rear shifting device to change the other of the front shift position and the rear shift position with a delay time period in conjunction with the one of the front shifting device and the rear shifting device in response to the user input. The shifting controller is configured to change the delay time period based on at least one of a gear ratio, the rear shift position, and a current rotational speed of a bicycle crank.

摘要： A method for prompting bicycle gear shifting includes collecting cycling data of a user during cycling, comparing the collected cycling data with cycling data samples in a preset gear shifting strategy library including correspondence relationships between preset gear shifting strategies and the cycling data samples, and when the collected cycling data matches one of the cycling data samples in the gear shifting strategy library, outputting the gear shifting strategy corresponding to the cycling data sample to the user.

摘要： A gear shifting system for a human-powered chain- or belt-driven vehicle includes a wheel speed sensor, a cadence sensor, a gear changer position sensor, a tension sensor, a clinometer, a controller and a gear changer actuator. The wheel speed sensor senses a speed of a wheel, while the cadence sensor senses a drive rate that a torque drive member drives a torque-transmitting member. The gear changer position sensor senses a position of a gear changer that positions the torque-transmitting member with respect to a plurality of gears. The tension sensor senses a tension of the torque-transmitting member that is transmitting a torque applied to the torque-transmitting drive member to a gear. The clinometer senses an inclination of the vehicle. The controller generates a control signal based on the sensed wheel speed, the sensed torque-member drive rate, the sensed torque-transmitting member tension, the sensed vehicle inclination and the sensed gear changer position. The gear changer actuator is coupled to the gear changer and moves the gear changer in response to the control signal by positioning the torque-transmitting member with respect to the plurality of gears.

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： An automatic control system includes a host connected to the actuator and the inputting device of a bicycle. The actuator controls the motor to drive the mechanical structure to generate a displacement. The inputting device receives the external information by manually entering or automatically sensing via the inputting device to obtain an inputting parameter. In each riding journey of the predetermined path, the host records the inputting parameter that the controller of the actuator drives the motor based on and the time spent for the riding journey to form a riding information. When the rider rides the bicycle on the predetermined path again, the host selects one of the riding information, which has the shortest time spent for the riding journey, as an operating parameter for controlling the actuator, so that the host automatically controls the actuator based on the operating parameter to prevent the cyclist from distracting.

摘要： This system creates a virtual image of the user's entire operating environment using a combination of hub speed, crank speed, inclination, and acceleration measurements. With this information, the system is able to understand the output torque and speed, and through control of the transmission, change the “gear ratio” to achieve a more desired operating condition based on the individual user's preferences. In addition, this system is designed to also work with a continuously variable transmission to avoid the shortfall of the state of the art systems, which can only get within a wide range of the optimal cadence because of the fixed ratios of a derailleur system.
