Abstract: A suspension system for a bicycle includes a first body defining a hollow interior, a second body configured to slide linearly within the hollow interior along an axis, and a rod disposed partially within the hollow interior and engaged with the second body. The rod extends along the axis. The suspension system also includes a sensor disposed outside of the hollow interior. Linear movement of the second body within the hollow interior along the axis is configured to create rotational movement of the rod about the axis, and the sensor is configured to detect the rotational movement to determine a linear displacement of the second body.

Abstract: An air spring includes a first body; a first piston sealed against a first wall of the first body; a cup having a second wall; and a second piston, wherein the cup and the second piston are configured such that: in an extended position, the second piston does not seal against the second wall, in an intermediate position, the second piston seals against the second wall, and as the first piston moves from the intermediate position to a compressed position, a spring rate of the air spring will increase at a higher rate than if the second piston were not sealed against the second wall.

Abstract: An air spring includes a first body; a first piston cooperating with the first body to define a pressurized first chamber including a gas, the first piston configured to slideably move relative to the first body; a pressurized second chamber; a flow passage between the first chamber and the second chamber; and a seal to selectively permit or restrict flow between the first chamber and the second chamber depending on a position of the first piston with respect to the first body.

Abstract: According to some embodiments, an adjustable assembly for a bicycle includes a lower tubular support configured to be attached to a bicycle frame; an upper tubular support configured to be attached to a bicycle saddle; an expansion portion support member positioned within an interior space of the lower tubular support; an expansion portion disposed at an upper end of the expansion portion support member; and a resilient member configured to provide an upwardly-directed force to the upper tubular support to provide movement of the upper tubular support away from the lower tubular support.
