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 in the upper tube that divides the upper tube into a first chamber and a second chamber. The first and second chambers are filled with fluid. The piston defines a fluid passageway between the first chamber and the second chamber. The height adjustable seat post includes a plug and a seal carried by the plug. The plug is moveable in a linear direction between a closed position in which the seal is engaged with the piston to block fluid flow through the fluid passageway and an open position in which the seal is spaced from the piston to enable fluid flow through the fluid passageway.

Abstract: An e-bike interface is a hybrid wired/wireless e-bike control system that integrates wireless bicycle components into operation of an e-bike. The e-bike interface provides a frame-mounted control and display that is wired to, for example, an assist motor and a battery, and provides a wireless communication bridge between wireless bicycle components and corresponding wireless controls located on a handlebar.

Abstract: A torque sensor for a bicycle includes a coil. The torque sensor may include a support that is disposable around a device of the bicycle, such that the support and the device of the bicycle are separated by an air gap. The torque sensor may also include an excitation coil supported by the support, and a sense coil supported by the support at a distance away from the excitation coil in an axial direction of the support. The excitation coil is configured to induce a voltage and/or current in the sense coil via the device of the bicycle when the support is disposed around the device of the bicycle. The induced voltage is related to a torque in the device.

Abstract: An electrically actuated component of a bicycle includes a first controller configured to receive a data stream from a second controller. The data stream includes one or more packets received by the first controller. For each of the one or more packets received by the first controller, the first controller is configured to identify a number of the one or more packets of the data stream received by the first controller, and compare the identified number of packets to a predetermined threshold number of packets. After all packets of the one or more packets of the data stream have been received by the first controller, the first controller is configured to initiate, based on the respective comparison, an action of the electrically actuated component or another electrically actuated component of the bicycle when the identified number of packets is less than the predetermined threshold number of packets.

Abstract: Height adjustable seat posts for bicycles are described herein. An example apparatus includes a height adjustable seat post including a valve and an internal actuator to operate the valve to enable the seat post to expand or contract. The apparatus also includes a control device including a housing and a microcontroller in the housing. The control device is outside of the seat post. The microcontroller is to control power to the internal actuator based on wireless signals from a seat post actuator on the bicycle. The apparatus also includes a cable to electrically couple the seat post and the control device.

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: An electronic component for a bicycle includes a processor configured to receive first data from a first sensor configured to sense at least one sensed element disposed about a bicycle wheel as the sensed element rotates through a proximal region of the first sensor. The processor is further configured to receive second data from a second sensor. The second data is different than the first data. The processor is configured to determine a first speed based on a subset of the received first data when the sensed element is within the proximal region of the first sensor, and determine a second speed based on a subset of the received second data and the first speed when the sensed element is not within the proximal region of the first sensor.
