  • Bicycle control device and system
    Patent number: 10370061
    Abstract: A bicycle control system may be configured to automatically control a bicycle, or components thereof. The bicycle control system may include a system control device configured to provide a simplified shifting system wherein large changes in speed associated with starting and stopping do not require the full attention of the automatic shifting system. The shifting system, or a system control device configured for controlling the shifting system, may be configured to determine when to enter an automatic shifting control mode, establish parameters for the automatic shifting of the automatic shifting control mode, and/or compare detected activities and values of the bicycle to the established parameters.

  • Adjustable seatpost
    Patent number: 10358180
    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.

  • Bicycle steerer tube with variant stiffness
    Patent number: 10328993
    Abstract: A bicycle steerer tube is adapted to reside in a plane of travel of the bicycle. A thickness at a point on the wall of the steerer tube body in a lower section thereof varies as a function of the cross-sectional angle of the point to the plane of travel, with the wall thickness being at a maximum in the plane of travel. An inner wall of the lower section may be elliptical, with a minor axis aligned with the plane of travel and a major axis orthogonal to the plane of travel.
