A ski-attachable upright conveyance can have a swept-back handle, an upright frame, strengthening members, ski clamp attachments, a braking system, and a plurality of standing plates. The ski clamp attachments allow simple attachment to a variety of skis (skates, wheels, etc.) to form the base of the conveyance so that it can slide across snow, ice, etc. The standing plates provide a non-slip surface upon which a user places his/her feet, allowing the person to stand upright while operating the conveyance. A braking system can allow a user to safely control their speed, stop, etc. The upright frame sweeps upwards before joining the swept-back handle. The frame locks the ski clamp attachments together and provides rigidity. Additional rigidity and support can be added via strengthening support members. A user can vary the pressure and forces exerted on the swept-back handle to assist in steering.

A cart may include a door forming a bed of the cart and a set of wheel assemblies. The cart may be configured to travel along a pair of railroad rails. Each wheel assembly may include a wheel rotatable about an axis and a guide structure configured to engage a side of one rail of the pair of railroad rails. The cart may include a handle, coupled to a wheel assembly.

A cart may include a door forming a bed of the cart and a pair of wheel attachment assemblies. Each wheel attachment assembly may include (a) a fender having a planar expanse configured to abut a lower major face of the door, (b) a clamping member coupled to the fender, the clamping member configured to be coupled to an upper major face of the door and abut an edge face of the door, and (c) a wheel fork coupled to the fender and configured to be coupled to an axle of a wheel. The cart may include a handle clamp configured to be coupled to an edge portion of the planar member and a handle configured to be coupled to the handle clamp.

A scooter having a riding platform rotationally engaged to a front steering assembly is provided which significantly increases the ability of riders to perform tricks. The riding platform is rotationally engaged to the steering column which itself may be employed as a riding platform. An optional mechanism may be employed whereby the riding platform is rotated by a spin of the steering column with the handlebars. The scooter may also be equipped with skids to allow employment in the snow or on ice.

A system and method for mounting one or more accessories to a vehicle with forks is disclosed. The system can include a frame comprising mounting plates, the mounting plates including at least an axle hole and a fork stop hole. The frame can also include frame rails to connect the mounting plate to an accessory mount. The system can be mounted to the forks of the vehicle using the axle hole and an axle. A fork stop can be placed in the fork stop hole and can include one or more interface points to fit the bottom of the forks. The fork stop can transmit forces from the accessory to the forks in a linear manner and to a location where the forks have additional strength. The fork stop can be designed such that it bends in response to an impact rather than breaking the forks.
