Abstract: 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.

Abstract: A siderail for a one-wheeled vehicle may include an elongate structural rail having a web extending from a first longitudinal end to a second longitudinal end. The rail is defined by four segments: a central segment defining a horizontal reference, a rear segment extending directly away from the central segment at an upward angle, a first forward segment extending directly away from the central segment at a downward angle, and a second forward segment extending directly away from the first forward segment at an upward angle.

Abstract: A moving wheel platform that minimizes wheel interactions with noncontinuous and uneven surfaces. The platform provides rotation-inhibiting structures onto or into the moving wheel platforms that aids with eliminating wheel bite.
