An auto-balancing transportation device having a wheel structure and foot platforms that pivot between an in-use and a stowed position. The pivot axis for each platform is provided within the wheel structure so that the force exerted by a rider when stepping on a foot platform is applied to the wheel structure at a point within the wheel structure, as opposed to external to it, which is unstable and may cause the device to tip over.

An individual movement equipment item, which is constituted by a pair of motorized skates, each of the motorized skates comprising: a plate in the form of a sole and having a front portion, which is articulated transversely relative to a rear portion, the plate having means for connecting to the foot or the shoe of the user, motorized means, which are formed by two portions, which are articulated transversely in order to form a front train and a rear train, connection means between the articulated plate and the motorized means, which connect the front portion to the front train and the rear portion to the rear train, characterized in that the angle of the longitudinal axis of the at least one of the trains of each of the skates forms an angle between 10° and 20°, and preferably of from 12° to 15°, with the longitudinal axis of the plate.

A boot for a roller skate system has a three-point fastening system for fastening the boot to a rail. The three-point fastening system includes three fastening devices, wherein the first fastening device is arranged in a central position in the heel region of the boot, the second fastening device is arranged on an outer side in the ball region of the boot, and the third fastening device is arranged on an inner side in the ball region of the boot. The rail that can be mounted on the boot is also described.

A modular skating assembly for switching between types of skating styles includes a boot that is configured to couple to a foot of a user. A first coupler is coupled to a sole of the boot. Each of a plurality of second couplers is complementary to the first coupler. Each of a plurality of skate modules is coupled to a respective second coupler. The respective second coupler is positioned to couple to the first coupler to selectively couple the skate module to the boot. The improvement is the plurality of skate modules being selectively couplable to the boot, such that a pair of the boots is selectively configurable to enable a particular style of skating, such as in-line skating and roller skating.

The present disclosure relates to a shoe fastening system. The shoe fastening system includes a shoe part, a rail, and an insertable intermediate adapter for compensating a distance between the rail and the shoe part. The shoe part can have a flat underside. The rail can have a surface in the heel area which is raised relative to a ball area. The shoe part can have at least one displaceable mounting plate for screwing in a fastening screw for the intermediate adapter. The intermediate adapter has three through-openings for inserting a fastening screw. The first through-opening is arranged in the center of the intermediate adapter, the second through-opening is arranged on one side of the intermediate adapter and the third through-opening is arranged on the other side of the intermediate adapter.
