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.

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.

Disclosed herein is a two-wheel vehicle suspension linkage. The suspension linkage includes a suspended body-1, a seatstay, a link body-3, a chainstay, a link body-5, and a link body-6 operatively coupled with one another. The link body-3 includes jointed connections with the suspended body-1 defining an IVC[1][3], the chainstay defining an IVC[3][4], and the link body-6 defining an IVC[3][6]. The chainstay includes a jointed connection with the seatstay defining an IVC[2][4]. The link body-5 includes jointed connections with suspended body-1 defining an IVC[1][5], seatstay defining an IVC[2][5], and the link body-6 defining an IVC[5][6]. A lower base line is defined by IVC[1][3] and IVC[3][4]. An upper base line is defined by IVC[1][5] and IVC[2][5]. The IVC[5][6] is located outside the upper and lower base lines. The suspension linkage includes a damper unit configured to resist movement between two or more of the bodies.

A tiltable vehicle (100) is described comprising a vehicle frame (102, 108), one front wheel (124), two rear wheels (112A, 112B) and two swing arms. The swing arms are pivotably coupled to a pivot point (121) on the vehicle frame at a first end, and to one of the rear wheels at an opposing end. A swing arm (41) is rotatable around a rotational axis (42) lying in a plane of symmetry of the vehicle frame (102, 108). Each of two linkages (63, 64) is coupled at a first end to one of the swing arms at the pivot point. The vehicle comprises two connection arms (53, 56) arranged between the linkages (63, 64) and one outer end of the rocker arm (40). The connection arms comprise resilient members (61, 62) comprising a number of Belleville springs arranged in at least two groups of rings so as to create a non-linear spring characteristic.
