A stand-up wheeled vehicle may include an electrically powered wheel and a deck configured to limit a maximum value of an angle of declination of the deck in a forward direction of travel, for example, to less than about 20 degrees, 15 degrees, 10 degrees, or 8 degrees. The deck may be asymmetric, such that a length of a first portion of the deck between the wheel and a first end of the deck is greater than a length of a second portion of the deck between the wheel and a second end of the deck. The deck may include a first surface, an opposing second surface, and a chassis disposed in the second surface. The chassis may have a cavity formed therein configured to receive a stand-up wheeled vehicle. A coupling mechanism may be utilized to removably retain the stand-up wheeled vehicle in the cavity of the chassis.

Roller-skates/sneakers with two pairs of separable wheels, by which the problem of their alternative adjusting for walking or roller-skating is solved, and which are at the same time safe, maneuverable, practical and simple to manufacture. The roller-skates consist of sneakers, which are laced with laces, an insole and two pairs of wheels separably fixed in the insole. The insole, which follows the shape of the foot and contains the front and rear axle and forms the load-bearing construction, is built into the lower part of the sneaker inside the sole. The wheel consists out of the middle plate lined with silicone rubber, an interchangeable mask, two bearings on the rims of central hollow part of the wheel, as well as two washers made of steel with two lids on the side of the wheel facing the sneaker.

A ground-engaging device that is capable of sustained rolling, stable braking, secure standing, and walking. In one preferred embodiment, the invention relates to a wheeled footwear device. In another preferred embodiment, the invention relates to a wheeled footwear platform. In yet another preferred embodiment, the invention relates to a wheeled artificial foot.

A skateboard truck that includes an inertia drive attached to a wheel. The inertia drive causes an inertial mass (i.e. flywheel) to turn at a higher speed then the wheel. During “pumping” of the skateboard the wheels accelerate and an inertia drive helps propel the skateboard given its inertia combined with the wheel inertia. The inertia drive may be configured to maintain skateboard stability at high speeds.

A roller blade ice wheel assembly for using roller blades on ice includes a plurality of blade wheel apparatuses each comprising a wheel body having a central wheel aperture, a pair of wheel sidewalls, and a wheel edge. The wheel edge is less than 0.5 cm. At least one bearing is coupled to the wheel body. The bearing receives an axle of a roller blade through a bearing aperture and the wheel aperture. Each of a plurality of spacers has a central spacer aperture to receive the axle of the roller blade. The plurality of spacers is positioned on both sides of the bearing to occupy space up to a wheel frame of the roller blade. The width of the blade wheel apparatus is dimensioned to equal the width of a wheel of the roller blade that is being replaced.

The present utility model discloses a roller skate. The rollers are divided into the front roller group and the rear roller group, and the rear roller group is rotatably disposed at the bottom of the skate body through the reversing mechanism, so that switching of the rear roller group between line arrangement and row arrangement is realized, the scope of application of the roller skate is effectively extended, and the roller skate has higher practicability.

A caster board can include a front platform, a rear platform, and at least two neck sections extending between the front platform and the rear platform. The neck sections can serve as a torsion element allowing twisting of the front platform relative to the rear platform. An aperture between the neck sections can be configured to receive an insert. The insert can alter a structural characteristic of the caster board, such as the torsional stiffness of the caster board.

An electric weight sensing skateboard using one or more strain gauge systems to detect rider-induced strain on one or both trucks, an inertial sensor to detect accelerations and balance position, and wheel speed sensors. Throttle is controlled by rider position, for example, lean forward to increase speed, lean back to slow down. Several drive methods include a driver position detection velocity setpoint control, torque setpoint control, and direct velocity/torque control. A throttle remote is note required. Rider weight activates the motors.

A multi-link wheel base includes a main body composed of a plurality of links connected in series and wheels provided on the main body, and the wheels are provided on the link assembly the link assembly includes an intermediate link and an end link, wherein both sides of the intermediate link are provided with a rotational connection position, one side of the end link is provided with a rotational connection position, and the rotational connection positions on the adjacent link assemblies are rotationally connected by means of a connecting device.
