A bicycle comprises a front wheel; a rear wheel; a frame comprising a main frame portion and an articulating frame portion, the articulating frame portion comprising: a lower arm pivotally supported at a first axis by the main frame portion; an upper frame link pivotally supported at a second axis by the main frame portion; an upper arm pivotally coupled to the upper frame link at a third axis; an upper shock link pivotally coupled to the upper frame link and the upper arm at the third axis; and a lower shock link pivotally coupled to the main frame portion and the lower arm at the first axis; and a shock absorber having a first end pivotally supported at a fourth axis by the main frame portion, and a second end pivotally supported at a fifth axis by the upper shock link and the lower shock link.

A position adjusting system for use in a vehicle includes a seat for supporting a rider, a rear wheel and a steerable front wheel, a steering arrangement including a handle bar for allowing the rider to control the steerable wheel, and a hub for interconnecting the components of the wheeled vehicle. The steerable wheel is steerable about at least two axes. The position adjusting system includes an adjustable seat support movably connected to the hub, an adjustable handle bar support movably connected to the hub, and a releasable position locking system configured to lock the position of the components of the vehicle relative to the hub. The hub includes a first portion and second portion, wherein the first and second portions are moveably connected to one another, such as by pivoting, sliding, or a combination of pivoting and sliding.

A bicycle may include a front triangle and a rear suspension system that couples the front triangle to a rear wheel and is dampened by at least one shock absorber. The rear suspension system includes a six-bar linkage having two ternary links separated from each other by one or more binary links, such that the two ternary links do not share a common joint. One of the ternary links may comprise a chain stay. In some examples, the other ternary link may comprise the front triangle. In some examples, the other ternary link may comprise a rocker arm coupling a seat stay link to the shock absorber.

An assembly including a hollow outer tube, and a hollow inner tube fitted within the outer tube and adapted to be slidably engageable with the outer tube, and a sensor-less measurement system adapted to measure the capacitance between the inner tube and the outer tube, where relative movement between the inner tube and the outer tube is derived from the change in measured capacitance between the inner tube and the outer tube.

A high performance motorcycle having a frame, engine suspension, and rear wheel drive system that enables rider foot positioning close to the longitudinal centerline of the motorcycle and an overall aerodynamic profile. The engine suspension, centering and damping system allows for lateral movement while damping vibration and unwanted oscillations. The rear wheel drive includes a driven pulley axially disposed on a rear wheel axle, a drive pulley configured to receive motive output from the motorcycle engine, an idler pulley disposed above a line between the axes of rotation of the drive pulley and the rear wheel axle, and a belt or chain disposed around and operatively connecting the drive pulley, the driven pulley and the idler pulley, wherein the idler pulley and the drive pulley configured so as to provide substantially constant tension to a belt or chain over the range of travel of the rear suspension.

A vehicle includes a main vehicle body, a suspended assembly that supports the main body of the vehicle, a suspension arrangement for connecting the suspended assembly to the main body of the vehicle, and a steering system for steering the suspended assembly. The suspended assembly assisting in providing directional control of the vehicle and stability in a lateral direction relative to a normal straight-ahead direction of travel for the vehicle. The steering system including a first steering arrangement that controls movement of the suspended assembly relative to the main vehicle body such that the suspended assembly pivots about a first steering axis. The steering system further including a second steering arrangement that controls movement of the suspended assembly relative to the main vehicle body such that the suspended assembly pivots about a second steering axis with the second steering axis being different than the first steering axis.
