A motorized wheel assembly adaptable to skateboards provides drive motor and power sources and controls for the directed control of forward or backward propulsion of the skateboard using throttle and braking controls, the motorized wheel, and all skateboard wheels. Weight transfer assemblies for the motorized wheel transfer a portion of a skateboard rider's weight through the front mounted motorized wheel to the ground surface creating sufficient traction for the motorized wheel to propel the skateboard. One weight transfer assembly embodiment provides a pivoting, compression based mounting bracket. Separate embodiments of the weight transfer assemblies include single or dual shock absorbers.

The present invention refers to a roller skate with a single wheel comprising a wheel (2110, 2120); a connection means (230) configured so as to allow the connection of a shoe (S); characterized in that the wheel is made up of a first circular element (2110) and a second circular element (2120), inside the first circular element, between which a rolling element (2130) is arranged, configured so as to facilitate the relative movement of the first circular element (2110) with respect to the second circular element (2120); and in that the connection means (230) is connected to the second circular element (2120) and is configured so as to position the shoe (S) at least partially inside the first circular element, preferably in an orientable manner according to any direction with respect to the second circular element (2120).

Skateboard components including a skateboard brake, skateboard base-plate, and skateboard hanger, are provided. The brake comprises a hanger, a pivot cup, and a push-rod extending through the pivot cup. A movement of the push-rod is translated into a braking action. The baseplate comprises a bracket and a trigger, wherein the trigger is configured to displace a push-rod extending from the baseplate and toward a hanger of the skateboard. The hanger comprises a pivot cup and a thrust-pin, wherein the thrust-pin is configured to be moveable by a push-rod extending through the pivot cup. Related methods and kits are also provided.
