A hands-free personal hydration delivery system has a tubing assembly that has one end that detachably connects to a feed tube for a container of fluid worn on the back or torso of a user. The other end of the tubing assembly is coupled to a bite valve which is opened when manipulated by the user's mouth to allow fluid to be drawn by suction applied by the user, and is closed when not being manipulated so as to cut off fluid flow in an air-tight condition. An intermediate portion of the tubing assembly is mounted on the user's head or to the user's headgear at a position of higher elevation than the user's mouth. This allows fluid to be drawn to the elevated position and flow downward from there to the user's mouth by gravity feed. The fluid flow can then continue with little suction effort due to the gravity feed and siphoning effect of fluid from the container. The tubing can be mounted using retainer loops or other type of fasteners attached to a helmet, sports cap, head band bracket, headphone bracket, headband, or an earpiece worn by the user. The hydration delivery system is especially useful for bicycling, canoeing, mountain biking, kayaking, canoe paddling, and rowing environments.

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 means 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.

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.

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.

Pneumatic tires adapted to use on bicycles have a number of criteria that need to be evaluated. For high performance bicycle riding, such as in mountain bike races, it is advantageous to optimize performance. Standard tires with tubes have ease of repair in the replacement of a punctured tube, have the ability to maintain pressure for long periods, and do not require special adaptation of the rim for sealing.

A bicycle frame (10) having a rear passive suspension system configured to elastically deflect predominantly in a vertical direction under normal cycling loads so as to better isolate the rider from road-surface irregularities and roughness, while simultaneously maintaining or improving rigidity in other directions so as to preserve or improve handling. The frame (10) has a pair of upper chain stays (18) that control the rear wheel motion rigidly in five of the six degrees of freedom with stiffness comparable to existing road, cyclocross, hybrid, city, or hardtail mountain bicycle designs, while simultaneously allowing deflection of the tubular members and a significant amount of vertical movement of the rear wheel for ride compliance in order to improve comfort, handling, and safety.

A wheelchair that has the ability to change quickly and easily the front casters of the wheelchair to another set of front casters intended for a different usage. This usage includes: an ‘everyday’ chair set up that uses narrower rear tires and smaller front casters; a snow chair set up with wide rear tires and larger front casters (or skis in place of casters); a beach set up with extremely wide rear tires and balloon front casters placed forward of the front of the frame; a hiking set up with mountain bike rear tires and over sized youth mountain bike front casters set); or a beach set up with extremely wide rear tires and balloon front casters placed forward of the front of the frame. A user may also mix and match front casters and rear wheels to form a different combination not listed above.

A bicycle frame set with front and rear suspension systems, where a seat point is defined by an intersection of a central axis of the seat post with a top surface of the seat, and a seat tube angle is defined as an acute angle formed between a first line parallel with the ground surface and extending through the seat point and a second line extending from the crank axis to the seat point. An initial seat position is defined when the suspension systems are in an uncompressed state. The frame is configured such that in the initial seat position the second line is located at least about 575 mm from the crank axis and the seat tube angle is at least 75.5 degrees.

The invention discloses a non-inflatable mountain bicycle wheel. The non-inflatable mountain bicycle wheel comprises a plurality of tread units, wherein the plurality of tread units are combined together to form an annular tire; a certain gap is remained between the adjacent tread units; each tread unit is connected with a rim arranged on a tire inner ring through an air spring; an inner ring which is fixedly connected with the air spring is mounted in an annular space formed by each tread unit and the rim; the rim is internally provided with a wheel disc; each air spring comprises an air spring rod; a connecting disc is mounted at each of the top, middle and bottom of each air spring rod; the connecting discs located at the tops are connected with the tread units through bolts; the connecting discs located in the middles are connected with the inner ring through bolts and the connecting discs located at the bottoms are connected with the rim through bolts.

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.
