Abstract:
A structural element of a cycle includes at least one tubular sheath provided with an outer wall delimiting, with an inner partition, at least one cavity in which a vibration damping system is accommodated. The sheath includes at least two internal cavities, each delimited between the inner partition and the outer wall, one of the internal cavities forming a housing in which the damping system is accommodated and attached.
Abstract:
The present invention is a bicycle having a frame capable of flexing under downward force so that when downward force is applied a front spring assembly and a rear spring assembly are able to store and release the energy allowing the bike to jump in the air. The spring assemblies of the present invention use bow springs made from fiberglass/epoxy, graphite/epoxy, or fiberglass/nylon instead of traditional coil springs. The bow springs allow the spring assemblies to return a greater amount of energy than their coil spring counterparts while keeping overall weight of the spring assembly down.
Abstract:
The invention relates to a bicycle frame including a base frame and at least one device which is mounted on the base frame, provided in the form of a brace structure, and has an accommodating area for accommodating a wheel. The invention also relates to a bicycle fork and to a method for producing a bicycle frame.

Abstract:
A vibrator comprises at least two leaf springs, both ends of which are connected to a base and a supporting member, one of the two ends of each leaf spring is secured to the base or the supporting member, while the other end is connected by hinge. Said device will make oscillatory vibration when external force is applied to the supporting member. Since one end of the leaf springs is connected by hinge, the vibrator can have larger vibration amplitude and better submission strength.
Abstract:
An improved bicycle rear suspension system with a triangular wheel suspension component comprising three members; a planar truss chainstay member with a wide lateral side and a thin vertical side, adapted to be longitudinally and laterally rigid and vertically flexible; a seatstay member with an integrated shock absorbing means adapted to dampen the suspension movement, the shock absorbing means being a long-travel, short-length shock absorber with angular deflection capability; and a seat tube member, arranged in a triangular configuration wherein one, two, or all three junctions between the members are pivotless, thereby eliminating rotating pivot elements and providing a low maintenance requirement, durability, high reliability, low manufacturing costs, progressive springing and damping, a comfortable ride, a compact size, and light weight, while increasing lateral and torsional rigidity and wheel travel, and maintaining the strength and aesthetic appeal of the traditional diamond frame.
Abstract:
A front wheel mounting for bicycles consisting of a pair of arms adapted to be pivoted at their rearward ends to lower ends of the usual fork legs of the bicycle for vertical pivotal movement, the front cycle wheel being rotatably mounted between said arms at selective points along the lengths thereof, and a pair of angled struts each pivoted at its lower end to one of said arms at selective points along the length thereof, and at its upper end to the associated fork leg in spaced relation above the connection of said arm thereto, said struts being resiliently yieldable in compression whereby to provide a spring mounting for said front cycle wheel.
Abstract:
THE CYCLE COMPRISES A SADDLE MOUNTED ON ITS FRAME TO THE REAR OF THE HANDLEBARS AND A PEDALING MECHANISM MOUNTED ON ITS FRAME IN FRONT OF THE HANDLEBARS, THE PEDALING MECHANISM BEING OF A RECIPROCATING CONSTRUCTION AND CONNECTED TO THE REAR WHEEL BY LENGTHS OF DRIVING CHAIN.
