Mobilized platforms are disclosed herein. The mobilized platforms can include one or more fork hangers attached to a platform with a cog-hub assembly attached thereto. The fork hangers can be attached to the cog-hub assemblies such that each fork hanger is attached to a cob-hub assembly at both a first cog-hub assembly end and a second cog-hub assembly end opposite said first cog-hub assembly end. 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.

According to some embodiments, a manually-powered movable device comprises at least one wheel configured to move when a user operates the device, an electrical energy generating assembly, wherein the electrical energy generating assembly comprises a magnet assembly and a coil assembly, wherein the magnet assembly is configured to move when the at least one wheel is moved, wherein the coil assembly is configured to remain stationary relative to a frame of the device when the at least one wheel is moved, and wherein relative movement between the magnet assembly and the coil assembly generates electrical energy, at least one wire assembly coupled to the electrical energy generating assembly, and at least one output device coupled to the at least one wire assembly and configured to contribute to creation of a desired effect.

In a preferred embodiment a wheeled platform apparatus and method for use in rolling on a surface are provided. The apparatus includes a platform having a top surface, a bottom surface, a front portion, a center portion, a rear portion, and a first wheel and a second wheel that interface with or are positioned below the bottom surface of the platform to facilitate rolling movement of the platform. The apparatus may further include an attachment device interfacing with the top surface and the footwear, as well as a footrest to support the forefoot of another foot, or footwear.

An electric roller skate in the present invention includes a shoe body, a roller frame, a driver, a rotation speed detection device, and a controller. The controller receives rotation speed information of the rotation speed detection device and accordingly controls the driver to start to drive the rollers to rotate. The present invention further provides a control method for the electric roller skate described above. The controller is capable of controlling the driver to start to drive the electric roller skate to slide according to the detected rotation speed information. Through the above arrangement, the solution can help a user to skate in a more labor-saving manner and reduce fatigue of the user. Meanwhile, the driver is started in a mode closer to a conventional sliding mode, is higher in convenience and intelligence, reduces use difficulty and makes user experience better.

The invention discloses a torque strengthening device for land surfboard adapters, comprising an upper connecting plate and a lower connecting plate, wherein a number of tension springs are connected between the upper connecting plate and the lower connecting plate; the upper connecting plate and the lower connecting plate are provided with the same number of evenly arranged spring connecting blocks on the side facing the tension springs; the number of the tension springs is twice the number of the spring connecting blocks on the upper connecting plate, and each of the spring connecting blocks is provided with two spring connecting holes; the spring connecting blocks of the upper connecting plate and the spring connecting blocks on the lower connecting plate are alternately arranged. The invention can replace tension springs with different torques to obtain different surfing feelings.

A system, method, and apparatus for replicating the experience of snow skiing on dry land using a roller land ski with an ability to move and stop consistent with mechanics of an actual snow ski. Each land ski includes a rigid platform with a binding for engagement with a specialized boot, a pair of biased omnidirectional casters supporting said rigid platform, but mounted to a top surface of said platform, and a pair of trucks with a plurality of wheels along its curved axles. A pair of specialized boots constructed out of flexible lightweight material with a stiff support structure to fortify a user's foot and ankle from the forces created by the land ski are included in this system. The method includes calibration and selection of materials for both the board and boot in order to achieve the desired experience.

A modular skateboard assembly for facilitating a user to employ a pair of skateboards in the convention of a skateboard or roller skates includes a pair of skateboards which each includes a pair of rollers that roll along a support surface. Each of the skateboards is attachable together such that the pair of skateboards extends along a common axis thereby facilitating the pair of skateboards to be employed in the common convention of skateboards. Furthermore, each of the skateboards is detachable from each other thereby facilitating the pair of skateboards to be employed in the common convention of roller skates. Each of the skateboards includes a pair of foot restraints to restrain a respective one of a user's feet.
