An apparatus of a damper (46) for a bicycle comprising a housing defining a chamber, and a piston, movable in the chamber along a first direction. The apparatus further comprises a controllable means to vary the resistance to movement of the piston in the chamber, a sensor (62), and a controller (58) including a timer. Said sensor measures at least one dynamic quantity and produces an output signal based thereon. Said output signal is received by the controller, and said controller controls said controllable means based on said dynamic quantity as a function of time to control the level of damping. The invention further provides means for manually adjusting the level of rebound damping.

A two-wheeled vehicle, in particular a bicycle or a mountain bike, the vehicle being fitted with a rear suspension and comprising a front frame carrying a bottom bracket and an oscillating rear assembly carrying a driving rear wheel, said frame and said rear assembly being connected to each other via two pivot connections and via a damping system, wherein the first pivot connection is formed by a circular eccentric constituted in a casing carrying an eccentric pin, said casing being mounted to pivot in a housing in the front frame, while the rear assembly is fixed to the eccentric pin on either side of the casing, and wherein the second pivot connection is formed by a connecting rod constituted by a simple plate disposed in the general direction of the frame.

The present invention is a seat height adjustment mechanism for exercise equipment having a seat. Examples of such exercise equipment include: stationary exercise bicycles; road or mountain type bicycles; resistance strength training supporting racks or platforms (e.g., preacher curl benches, military or shoulder press racks, etc.) for use with free weights; and resistance strength training machines that employ as resistance weight plates, deflectable members, elastic bands, springs, hydraulic cylinders, pneumatic cylinders, etc. The mechanism comprises a member, a telescopic member, and an engagement member. The member extends upwardly and includes a rack. The telescopic member includes a first end telescopically received in the member and a seat end. The engagement member is coupled to the telescopic member and adapted to engage the rack.

An innovated rear suspension system for mountain bikes that includes five structural tubes—a force channeling tube, a front stabilizing tube, a rear stabilizing tube, a top tube, and a seat tube—connected to form an irregular polygon; reinforced with gussets, a torque conversion device pivotally connected to a compression strut, a shock-absorbing element and the force channeling tube, which transfers force or shock from the compression strut to the shock-absorbing element. The shock-absorbing element pivotally connected at the front to a pair of shock mounts attached to the force channeling tube absorbs and compresses force from the torque conversion device and transfers the force to the force channeling tube. The upward and forward direction of the force channeling tube guides the force along the force channeling tube propelling the bicycle and the rider forward, reducing jacking and efficiently utilizing pedal forces.

A bicycle frame design using plate frame structural elements for a high performance, full suspension bicycle having the ability to fold up in a package of compact size is provided. The main frame is formed by opposed plate frame elements (1, 2), patterned in the ergonomic dimensions and component arrangements therefrom used for contemporary mountain bikes. The patterned plate frame elements (1, 2) are cut from plate stock in a way that locates and mounts the operative elements in positions required for bike function. Such plate frame structure is of modular, lightweight, and weldless construction. A mechanically simple, lightweight rear shock absorbing system (7, 8, 9) is incorporated. The design routes cables in an internal arrangement, separating them from rider or other attached components or accessories on the inboard side of the plate frame structure. Overall geometry and dimensions of the configuration are adjustable to provide a universal fit for riders of various sizes. The opposed plate frame elements can be separate plates structures, or can be formed by folding a single blank having therein both opposed plate frame elements.

An adjustable coil spring system placed within a leg of a vehicle such as a mountain bicycle fork. The spring system comprises an adjustable first soft spring seated on top of a second firm spring having greater length than the first soft spring. A coupler assembly is positioned between two springs comprised of a threaded bolt threadedly received within a coupler. A spring adjustment mechanism may comprise a knob connected to the threaded bolt through a non-round shaped shaft, wherein the threaded bolt is disposed within the first soft spring. As the knob rotates, the coupler is moved up along the threaded bolt, decreasing the length of the first soft spring, thereby increasing firm spring characteristics of the spring system. As the knob rotates in an opposite direction, the coupler moves down, increasing the length of the first soft spring, thereby increasing soft spring characteristics of the spring system.

The present invention is related to a handlebar extension (1) mountable on a bicycle (2), such as a touring bicycle or a mountain bike, comprising an original handlebar (3) fastened to a handlebar stem (3A), characterised in that said handlebar extension (1) comprises means (12A, 12B, 13, 14) for attaching pivotally said handlebar extension (1) to the original handlebar (3), so that said handlebar extension (1) is free to rotate about the axis of the original handlebar (3) during riding, providing to the user a number of equilibrium riding positions.

Unique suspension apparatuses, systems and methods useful for mountain bicycles among other applications are disclosed. In certain exemplary embodiments the suspension is self adjusting to meet different performance objectives. The suspension may utilize pedaling force to substantially stiffen or lock out movement of the suspension, for example, during climbing. The suspension may change its performance under reduced pedaling force to provide performance characteristics desired when a rider is descending. Certain exemplary embodiments include a rocker arm connected to a first frame portion at a first rocker arm pivot, connected to a seatstay at a second rocker arm pivot, and connected to a second link at a third rocker arm pivot. The first link is connected to the first frame portion at a first link pivot, connected to the chainstay at a second link pivot, and connected to the shock and the second link at a third link pivot.

A vehicle frame, in particular a mountain bike frame or a trekking bicycle frame, comprises main frame element. A rear frame is pivotably connected with the main frame element. A damping element is provided between the rear frame and the main frame element. A first connection point of the damper element is connected with the rear frame and a second connection point of the damping element is connected with the main frame element. For the purpose of changing the frame characteristics, a displacing element is provided for the displacement of the first connection point. The locking of the displacing element is done with the help of an actuator element.
