A shock-absorbing bushing is provided for a skateboard and includes a first layer and a second layer. The first layer has first value of hardness. The first layer is provided with a through hole. The second layer has a second value of hardness. The second layer is coupled to an outside surface of the first layer. The first layer and the second layer are formed of plastic materials coupled together as a unitary body and exhibiting at least two different values of hardness, such as being flexible in the interior and stiff in the exterior, or being stiff in the exterior and flexible in the interior. The skateboard shock-absorbing bushing is mountable to the skateboard by for example being coupled to an axle of a retainer seat to which a roller support frame is mounted.

A ski has an upwardly rising front tip, a rear tail, and a midsection extending along a longitudinal axis of the ski between the front tip and the rear tail, the midsection including a waist section adapted for mounting a binding thereon. At least one stabilizing section is located between the front tip and the waist section or between the waist section and the rear tail. The at least one stabilizing section is offset from the longitudinal axis of the ski toward a first side of the ski. The stabilizing section may offset, toward and inside or an outside of the ski, a center of mass, a level of stiffness, or a damping effect of the stabilizing section. A pair of skis comprises such left and right skis. A stabilization device may be mounted on an ordinary ski.

A self-balancing board is provided, comprising a platform having a first foot deck portion to substantially support a first foot of a rider, and a second foot deck portion to substantially support a second foot of the rider. A wheel assembly is positioned between the first foot deck portion and the second foot deck portion along a longitudinal axis of the platform, and comprises a wheel having a rotation axis that is generally orthogonal to the longitudinal axis of the platform, and a motor unit driving the wheel. An orientation sensor senses the orientation of the platform. A controller receives data from the orientation sensor and controls the motor unit in response to the received data. At least one suspension interface between the platform and the wheel assembly has a single degree of freedom generally orthogonal to the rotation axis of the wheel and to the longitudinal axis of the platform, and biases the platform towards a rest position.

A goalie skate assembly has i) a plastic blade mounting member adapted to releasably receive a metal skate blade therein, and ii) a monocoque carbon fiber and resin composite skate boot body for receiving a foot of the user therein. The unitary structure of the skate boot body includes i) a sole portion, ii) a heel portion extending upwardly from the sole portion for receiving a heel of the user therein, iii) a pair of side portions extending upwardly from opposing sides of the sole portion, and iv) a lower portion extending downwardly from a bottom side of the sole portion so as to surround at least a portion of the blade mounting member. A toe cap mounted on the skate boot body includes a molded plastic outer shell and a liner formed of a fiber and resin composite material bonded to an inner surface of the outer shell.

One-person vehicle (1) for urban transport comprising a transport deck (2) for one user of the vehicle (1), trucks (3) for the displacement of said transport deck (2), and control arms (4) for said trucks (3) which are attached to said transport deck (2) so that they can pivot with respect to said trucks (3) when the user swings the deck (2) for changing the traveling direction of the vehicle (1), and is characterized by the fact that each of said trucks (3) comprises a pivot (5) to be inserted into one of said control arms (4) and a damper assembly (19) which is interposed between the pivot (5) and the arm (4) rotating about said pivot (5), allowing said damper assembly (19) to compensate on said arm (4) the weight force that swings the deck (2) and to drive the return to the centre of said arm (4) when said force yields.

An energy absorption corner assembly for gate-opening sections and gates of dasher board assemblies for a playing zone having a playing zone comprising: an elongate core section comprising a polymer material having a first durometer; a sheet of the polymer material having a second durometer, wherein the second durometer is greater than the first durometer, wherein the sheet of the polymer material covers an entire surface of the elongate core section(s) facing the playing zone.

A powered two-wheel vehicle includes a chassis extending between a rotatable front fork and a fixed rear fork. A deck is attached to the chassis to enclose a compartment. A front wheel is rotatably attached to the front fork and a rear wheel is rotatably attached to the rear fork via a hub motor. The steering assembly includes a head tube supported above and in front of the deck by a pair of arched frame tubes, a steering tube rotatably connected to the head tube, and a rotational damper connected between the head tube and the steering tube.

A skateboard truck for supporting a skateboard is disclosed. The truck includes a suspension device for allowing tilt and wheel turning and includes a return to level response to tilting. The truck includes features for allowing adjustment of the steering ratio.
