Various powered wheeled board vehicles are disclosed. In some embodiments, the vehicle includes a deck having a forward portion and a rearward portion. At least one front wheel can be connected with the deck under the forward portion. The front wheel can be configured to swivel about a first axis and rotate about a second axis. A powered wheel can be connected with the rearward portion. In some configurations, the rear wheel comprises a hub motor.

An adjustable wheel mobility vehicle can have a support structure for supporting a rider, a modular conveying feature with a wheel, and an attachment that physically and tightly secures the modular conveying feature to the support structure in at least two different positions. A tool-free mechanism can allow a user to free the modular conveying feature from the support structure for movement to another position. A system for adjusting a skateboard wheel position can include a wheel support structure having multiple wheel attachment positions, and a wheel assembly comprising a skateboard wheel and a base. The wheel can swivel with respect to the base and the base can join to the wheel support structure. The base and wheel support structure can tightly join to prevent rotation of the base with respect to the wheel support structure and that tightly retain the base in a first attachment position. A release feature can allow a user to easily loosen the base and reposition it in a second attachment position.

A stand-on land vehicle, for simulating snow skiing, features a side-by-side pair of platforms, coupled and supported (a) at the rear by an angled tilt-turn mount under each, integrated with a shared axle assembly fitted at its ends with a pair of rear wheels, located at opposite sides of the vehicle, and (b) at the front by a tilt-turn mount system including a strut/spacer framework attached to a pair of user handling bars, and to at least one front wheel, typically a roller, via an associated inclined swivel-caster type mount assembly. This novel combination accomplishes dual-platform tilt-turning in response to the user's body movements that simulates the superior snow-skiing technique of skewing the skis longitudinally for banked turns as in zig-zagging downhill. The invention actually enables sustained self-propulsion, zig-zagging on level concrete and paved surfaces, powered only by user body movements during turns and enhanced by low-friction roller-wheels for free-wheeling coasting on straight runs, and is thus capable of providing, on dry land, both recreational pleasure and highly effective training and practice for snow-skiing for snow skiers of all ages and skill levels.

A summer style ski having three different types of wheels aligned to allow the ski to travel on non-snow or ice surfaces and to create the feel of carving or turning on a paved surface.

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.

Various powered mobility systems for users are described. The powered mobility system can include at least one powered skate. The powered skate can include a platform, a plurality of wheels, and a motor assembly. The motor assembly can include a motor. The motor can be powered by a power supply. A motor control can be implemented to determine when power is supplied to the motor from the power supply.

A caster board can include a front platform section connected by a torsion bar or other neck portion to a rear platform section. The caster board can be convertible between a first configuration in which the caster board has three wheels, and a second configuration in which the caster board has two wheels. In the first configuration, the rear platform section can be supported by two wheels laterally offset from a longitudinal axis of the caster board. In the second configuration, the rear platform section can be supported by one wheel aligned with a longitudinal axis of the caster board. The rear platform section can include at least three mounting locations configured to have caster assemblies installed therein.

Various powered personal mobility vehicles are disclosed. In some embodiments, the vehicle can include a deck having a forward portion, a rearward portion, and a neck portion. A front swivel wheel assembly and a rear swivel wheel assembly can be connected with the deck. In some embodiments, the front swivel wheel assembly comprises a motor.
