A front wheel pivoting assembly for a bicycle allowing for a front wheel of the bicycle to be articulated includes a bracket, a secondary head tube, a pivot unit, and a controller. The bracket and controller are mountable to an integral head tube and a handlebar, respectively, of a frame of a bicycle lacking a front fork assembly and a handlebar stem. Lower and upper ends of the secondary head tube engage the front fork assembly and the handlebar stem, respectively. A hinge is engaged to and extends between the bracket and the secondary head tube. The pivot unit is engaged to the bracket and is operationally engaged to the secondary head tube, allowing for reversible positioning of the secondary head tube. The controller selectively actuates the pivot unit, allowing a user to pull back and to push forward on the handlebar to extend and retract, respectively, the front wheel.

Example bicycle suspension components are described herein. An example suspension component includes an air spring including an air spring body and a piston in the air spring body. The piston divides the air spring body into a first chamber and a second chamber. The air spring also includes a shaft extending into the air spring body. The shaft extends through the piston. The piston is slidable along the shaft. The air spring further includes a spring to bias the piston in a first direction relative to the shaft.

The saddle-riding motor vehicle (1; 107; 207) comprises a rear driving wheel (5; 105; 205) and a front steered wheel (7; 107; 207). The front steered wheel (7; 107; 207X, 207Y) is connected to a rotatable arm (9; 109; 209X, 209Y) provided with a rotary motion about a steering axis (A-A). A wheel support (37; 137) is connected to the rotatable arm (9; 109; 209) with the interposition of a suspension (17; 117; 217X, 217Y) comprising a shock absorber (22; 122). The suspension (17; 117) comprises a Roberts four-bar linkage.

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 spring for a suspension is described. The spring includes: a spring chamber divided into at least a primary portion and a secondary portion, and a fluid flow path coupled with and between the primary portion and the secondary portion. The fluid flow path includes a bypass mechanism, wherein the bypass mechanism is configured for automatically providing resistance within the fluid flow path in response to a compressed condition of the suspension.

The present invention relates to a vehicle body for a two-wheeled vehicle, the vehicle body having excellent shock-absorbing performance and enabling structure simplification since both a front wheel frame and a rear wheel frame can rotate with respect to a saddle frame so that shock is absorbed at both a front wheel and a rear wheel, even if shock is applied to either the front wheel or the rear wheel. The vehicle body for a two-wheeled vehicle comprises: a rotary frame comprising a saddle frame having a saddle mounted on the top thereof, a front wheel frame connected to a front wheel shaft, and a rear wheel frame connected to a rear wheel shaft, which are rotatably coupled to each other through a rotary support part; and a shock absorber which is provided between the saddle frame, the front wheel frame and the rear wheel frame, and which elastically supports, with respect to the saddle frame, the front wheel frame and the rear wheel frame that rotate upward toward the saddle frame around the rotary support part.

A suspension stabilizer and method are described which may be attached to a bike having front fork suspension to improve handling and reduce rider fatigue. The suspension stabilizer may include a counterweight, a spring assembly and a guide assembly. The spring assembly may be arranged to provide a spring force between the counterweight and the guide assembly to resist linear motion of the counterweight along a guide assembly axis. The counterweight and spring assembly may have a natural motion frequency of 3 to 15 Hertz and may be based on one or more characteristics of the front fork suspension.

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 front fork of a bicycle may include a suspension system that includes a damper. The damper may include a hollow tube with orifices that may be partially blocked by an adjustable blocker. A free end of the adjuster that adjusts the blocker may maintain its axial position in any rotational position. Ambient air may be introduced through a valve and retained in the suspension system. The suspension may include a mechanical spring in a chamber away from the valve that introduces the ambient air.
