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: A seat post assembly for a bicycle has a first tube with a first distal end and a second tube with a second distal end. The first and second tubes are movable relative to one another to establish a distance between the first and second distal ends. A first pressure chamber has a loaded pressure proportional to a load applied along the tube axis. A second pressure chamber has a second pressure not proportional to the load. A flow path connects the first and second pressure chambers. A valve is disposed along the flow path and is configured to move between a closed position closing the flow path and an open position opening the flow path between the first and second pressure chambers. An isolator of the valve is configured to nullify any resultant force produced by the loaded pressure of the first pressure chamber acting on the isolator.

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 electromechanical control system for a bicycle has a switch device, the switch device operating a switch between at least three positions. A control communication device transmits signals responsive to operation of the switch. The electromechanical control system includes an operation device configured to respond to signals transmitted by the control communication device. Signals transmitted by the control communication device include commands to listen and commands to operate.

Abstract: Responsive to a hydraulic piston advancing out of a piston housing in a second brake arm and contacting a piston cam surface of a first brake arm, the second brake arm pivots around a second pivot. As this is happening, a cam surface in the second brake arm lifts a contact surface of a first force transfer member of the first brake arm, imparting torque to the first brake arm which then pivots around a first pivot. The cam surface is shaped to impart synchronous motion to the first and second pad holders. Splitting one of the brake arms with a centering member permits a centering adjust feature.

CPC classification number: B62M9/135
Abstract: A support assembly for supporting a front derailleur at a bicycle frame is provided. The bicycle frame includes a longitudinal axis, a support portion arranged lengthwise about the longitudinal axis and a mounting portion projecting outwardly from the support portion. The front derailleur includes a base member attachable to the mounting portion of the bicycle frame at a derailleur mounting axis. The base includes a support mounting surface facing the bicycle frame. The support assembly includes a support member and a support member mount. The support member is displaceable relative to the base member along the support mounting surface of the base member. The support member includes a contact surface configured to contact the support portion of the bicycle frame. The support member mount is configured to attach the support member to the support mounting surface of the base member.

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.
