A human-propellable vehicle is described and comprises a chassis and a roller assembly mounted at or towards the rear of the chassis. The roller assembly is positioned to engage with a wheel of a second vehicle to permit the second vehicle to push the human-propellable vehicle.

A utility sled is formed from a lightweight material and includes a handle flexibly attached to the front end thereof. The handle includes a hook that is seated within a small opening of the utility sled when not in use. A pair of retractable wheels is attached to an exterior of each sidewall of the utility sled. The sidewalls are biased outward when no load is present. When loaded, the sidewalls advantageously tend to straighten vertically. The formed bottom of the sled includes a plurality of ribs which both add strength to the sled as well as function as sled runners when the wheels are retracted. The ribs operate to reduce friction between the sled bottom and the underlying surface.

A sliding method on ice-surface aims at solve the problems of power output and poor durability and the difficulty in large-scale promotion. An ice-surface sliding tool includes a seat board, a U-shaped rod, sliding plates, H-shaped connecting frames, a pushing device, a hand-operated chain wheel and a reversing gear. One end of the upper end surface of the seat board is provided with a backrest. The U-shaped rod is provided on the side wall of the other end of the seat board. The lower end of the seat board is symmetrically provided with two sliding plates in parallel to each other. The sliding plates are connected with the lower end surface of the seat board through the H-shaped connecting frames. The pushing device is rotationally provided between the two H-shaped connecting frames. The hand-operated chain wheel is on the upper end of the U-shaped rod through a support bar.

An illustrated view of an exemplary sled for transporting items across difficult terrain is presented. The sled is useful for providing a means to transport belongings across a flat hard terrain to a desired location in an efficient and easy manner.

Snow vehicle is disclosed. The snow vehicle includes a pair of runners configured to support the snow vehicle travelling over snow and/or ice, an electric motor, and a traction wheel, powered by the electric motor, and configured to cause a propulsion for the snow vehicle while rolling in contact with the snow and/or the ice. The traction wheel is positioned in front of the pair of runners.

In accordance with example embodiments of the present disclosure, the invention provides a sports apparatus having an upper surface and a lower surface, the upper surface designed to slide on slippery surfaces such as snow, ice or sand and the lower surface having wheels and thus designed to glide along smooth hard surfaces.

A motorized kayak cart is provided. The cart has a frame for supporting the hull of a kayak, a motor that drives two opposing wheels mounted on the frame, and stabilizing bars that contact a ground surface on which the cart rests and slides along the ground surface in order to maintain the cart in an upright position when the cart is in motion so that the cart does not tip over when in use.
