    Abstract: A torque sensor includes a contact sensor and a contactless sensor. An electric drive system for a bicycle includes an electric motor having a rotor rotatable about an axis. An output component is coupled to the electric motor and is rotatable about an axis. An input component is rotatable about the axis and is concentric with the output component and the rotor. A one-way clutch is disposed between the input component and output component. The contact sensor is coupled to the output component. The contact sensor is configured to measure a torque applied to the output component by the input component and provide an input signal. The contactless sensor is disposed between the output component and a fixed component. The contactless sensor is configured to provide an output signal proportional to the input signal

    Abstract: Height adjustable seat posts for bicycles are described herein. An example height adjustable seat post includes an upper tube and a lower tube configured in a telescopic arrangement. The height adjustable seat post includes a piston assembly in the upper tube that divides the upper tube into a first chamber and a second chamber. The piston assembly includes a valve to control fluid flow between the first and second chambers. The height adjustable seat post also includes an actuator to operate the valve. The height adjustable seat post further includes a connector assembly connected to the lower tube. The connector assembly is to be connected to a mating connector assembly on the bicycle. The connector assembly includes a magnetic connector including a housing having an end surface with an opening, first and second electrical contacts in the opening, and a magnet disposed in the housing and spaced from the end surface of the housing.

    Abstract: 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.

    Abstract: A method for controlling electronic shifting of a bicycle includes identifying, by a processor, a torque at a crank arm of the bicycle. The processor compares the identified torque or a parameter based on the identified torque to a predetermined band. The predetermined band has an upper limit and a lower limit. The processor determines a target cadence based on the comparison. The processor determines a cadence band based on the determined target cadence. The method also includes controlling the electronic shifting of the bicycle based on the determined cadence band. The controlling of the electronic shifting of the bicycle includes actuating a motor of a derailleur of the bicycle for the electronic shifting of the bicycle when a cadence of the bicycle is outside of the determined cadence band.

    Abstract: In an adjustment mode for a derailleur of a bicycle, acceleration values from an accelerometer of the derailleur are sampled as the derailleur moves through sprockets of a rear sprocket assembly. Acceleration signal powers are identified based on the sampled acceleration values, and potential rasping positions are identified based on thresholding of the acceleration signal powers. The identified potential rasping positions are compared to expected rasping positions, and adjustment for the derailleur is set based on a minimum error between the identified potential rasping positions and the expected rasping positions.

    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 a controller of the bicycle. The controller is configured to instruct an assist motor to activate based on the measured wheel speed and/or the measured crank cadence.
