The mobilized platforms can include additional features such as baseplates or transom plates. The cog-hub assemblies can also comprise wheel assemblies or connected cog-hub subassemblies. The mobilized platforms can also include a treading connected to the cog-hub assemblies.

Abstract: Motorized hub assemblies for use with platforms and the corresponding motorized platforms are presented. At least one of the hub assemblies can be a motor and can contain an internal motor to propel the platform when activated. In some embodiments, the motorized platform has two sets of motorized wheels or two sets or motorized treads for differential rate maneuvering. In some embodiments, different base platforms are mounted to a single set of wheels or a single tread to provide a sporty style ride. A handlebar can also be implemented for greater stability. In all cases, there is no requirement for an electronic stabilization platform.
