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: A battery system includes an auxiliary battery releasably coupled to a main battery. The main battery includes a charge controller and has a first output voltage. The main battery is configured to be electrically coupled to a bicycle drive unit and supply power to the drive unit. The auxiliary battery has a second output voltage. The auxiliary battery is releasably coupled to the main battery in series such that a total output voltage of the main battery and auxiliary battery is equal to a sum of the first and second output voltages.

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.

CPC classification number: B62J1/06

Abstract: A seat post assembly includes a first tube moveable along an axis between a first position and a second position and a second tube telescopically moveable along the axis relative to the first tube between a retracted position and an extended position. A positioning assembly configured to adjustably position the second tube relative to the first tube. An electric actuator is adapted to be automatically electrically connected to a power source when the first tube is moved from the first position to the second position, and automatically electrically disconnected from the power source when the first tube is moved from the second position to the first position. The electric actuator is movable to actuate the positioning assembly in response to an electrical current adapted to be transmitted from the power source when the first tube is in the first position to adjustably position the second tube relative to the first tube.

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: Bicycle component motion control begins when a motorized bicycle component is commanded to shift or actuate. The bicycle component motion control compares parameters of a component of the bicycle to be moved, to predetermined thresholds to provide safe shifting or actuation. The shift or actuation starts only when the battery voltage and the battery temperature are within predetermined acceptable ranges, respectively. Once the shift or actuation has started, the shift or actuation is aborted if the battery voltage remains below a predetermined low voltage threshold for a predetermined amount of time. If the shift or actuation is aborted when the component is in a position, in which the bicycle may not operate at a particular level or is inoperable, the shift or actuation command is modified to move the component to a previous position or an intermediate position.
