Abstract: A modular, multi-part roller skate is provided. The multi-part roller skate includes a roller skate body, a front wheel assembly, a rear wheel assembly, a support surface for supporting a footwear of a user, and at least one securing element for securing the footwear to the support surface. The multi-part roller skate is configurable as a modular roller skate with a removable pair of rear wheels, an interchangeable modular roller skate and ice skate, and an interchangeable modular roller skate and cross-country ski/snowshoe. In some embodiments, the multi-part roller skate can also be configured as a length-adjustable skate with a length adjustable skate body that includes separate front and rear foot support structures.

Abstract: Provided is an accessory for a self-balancing board having two lateral foot-deck ends, each being coupled to a motor that drives a wheel in response to its orientation. The foot-deck has at least one sensor that is triggered when a rider is in a riding position thereon. The accessory includes a chassis, at least one travel surface-contacting element, a seat, and an engagement structure that releasably engages the self-balancing board. At least one sensor-triggering element is actuatable between an idle position and a triggering position, wherein the at least one sensor-triggering element triggers the at least one sensor. At least one control member actuates at least one of the engagement structure and the at least one sensor-triggering element to control the orientation of the lateral foot-deck ends. At least one manually actuatable actuator actuates the at least one sensor-triggering element between the idle position and the triggering position.

Abstract: An accessory for a self-balancing board is provided. The self-balancing board comprises a foot-deck having two lateral foot-deck ends. Each lateral foot-deck end is coupled to a motor that drives a wheel in response to an orientation of the lateral foot-deck end relative to a horizontal plane. The foot-deck has at least one sensor that is triggered when a rider is in a riding position thereon. The accessory includes a chassis, at least one travel surface-contacting element coupled proximal to a first longitudinal end of the chassis to facilitate travel of the chassis over a travel surface, and a seat coupled to the chassis and configured to support the rider. The accessory further includes an engagement structure that releasably engages the self-balancing board and fails to trigger the at least one sensor.
