The present disclosure provides a detachable training wheel apparatus for mounting to the underside of a skateboard tail or nose to assist with balancing a user during manoeuvres which require tipping of the skateboard onto two wheels, while allowing the board to continue rolling along the ground with minimal friction. The apparatus comprises a single wheel mounted to a mounting board by a pair of supports and a central bushing, with the opposing side of the mounting board having a flat surface provided with attachment means for detachably coupling to the skateboard underside, such as a hook and loop surface.

In an aspect there is provided a swing scooter, comprising a frame, a steering member, a front wheel, at least two support legs, and at least two platforms. A rear wheel support is pivotally attached each support leg. A rear wheel is rotatably attached to each rear wheel support. Each platform is movably attached to an associated support leg, and positioned for supporting a foot of a user. Each platform has a longitudinal platform axis and is movable between a first position in which the platform is angled down laterally towards a first lateral side of the swing scooter, and a second position in which the platform is angled down laterally towards a second lateral side of the swing scooter. The platform is movable to the first and second positions by movement of the foot of the user.

A system, method, and apparatus for replicating the experience of snow skiing on dry land using a roller land ski with an ability to move and stop consistent with mechanics of an actual snow ski. Each land ski includes a rigid platform with a binding for engagement with a specialized boot, a pair of biased omnidirectional casters supporting said rigid platform, but mounted to a top surface of said platform, and a pair of trucks with a plurality of wheels along its curved axles. A pair of specialized boots constructed out of flexible lightweight material with a stiff support structure to fortify a user's foot and ankle from the forces created by the land ski are included in this system. The method includes calibration and selection of materials for both the board and boot in order to achieve the desired experience.

In a preferred embodiment a wheeled platform apparatus and method for use in rolling on a surface are provided. The apparatus includes a platform having a top surface, a bottom surface, a front portion, a center portion, a rear portion, and a first wheel and a second wheel that interface with or are positioned below the bottom surface of the platform to facilitate rolling movement of the platform. The apparatus may further include an attachment device interfacing with the top surface and the footwear, as well as a footrest to support the forefoot of another foot, or footwear.

The present invention relates to motorized platforms wearable by a user, for enhancing the speed of walking while maintaining stability and reducing overall weight, due to a simplified structure and relatively modest number of components.

An apparatus comprising a platform; a plurality of trucks coupled to the platform; and a roller assembly coupled to the platform, wherein the roller assembly is configured for an omnidirectional rotation, wherein the roller assembly is configured for an elastic biasing, wherein the roller assembly is driven by a motor.

A braking device is provided for an in-line skate where the braking device selectively alters the motion of the in-line skate depending upon the angulation of the in-line skate relative to a surface. As a user angulates or tilts the in-line skate, the braking device increasingly engages the surface to provide a braking force to alter the motion of the in-line skate.

Improved skateboards and methods of obtaining or providing skateboards with improved trucks. Trucks have two axles or axes, two primary wheels, and two secondary wheels, and skateboards have eight wheels, four in front and four at the rear portion of the skateboard. The four primary wheels support most or all of the weight of the skateboard when the skateboard is on a flat surface, and the two secondary wheels support the weight of one portion of the skateboard (e.g., front or rear) when the primary wheels cross a crack (e.g., a sidewalk contraction joint). In various embodiments, the secondary wheels are located outboard of the primary wheels. Further, in a number of embodiments, the axis of rotation or axle of the primary wheels remains parallel to that of the secondary wheels, whether the skateboard is going straight or turning.

A rear wheel support is pivotally attached each support leg. A rear wheel is rotatably attached to each rear wheel support. Each platform is movably attached to an associated support leg, and positioned for supporting a foot of a user. Each platform has a longitudinal platform axis and is movable between a first position in which the platform is angled down laterally towards a first lateral side of the swing scooter, and a second position in which the platform is angled down laterally towards a second lateral side of the swing scooter. The platform is movable to the first and second positions by movement of the foot of the user.
