A wheeled ski is disclosed that may include a flexible member. The wheeled ski may also include a first wheel assembly that includes a first wheel with a first-wheel first rotational axis and a first-wheel second rotational axis. The first-wheel first rotational axis and the second-wheel second rotational axis may intersect. The wheeled ski may also include a second wheel assembly that includes a second wheel with a second-wheel first rotational axis and a second-wheel second rotational axis. The second-wheel first rotational axis and the second-wheel second rotational axis may intersect. The first wheel assembly may further include a first axle coupled with the flexible member and a first rod that extends through the first axle. The second wheel assembly may further include a second axle coupled with the flexible member and a second rod that extends through the second axle.

The invention relates to a sporting device (1), in particular a touring ski assembly. The sporting device (1) comprises a sliding body (2) on which a bottom side (3) is designed as a sliding surface (4). Furthermore, the sporting device (1) comprises a binding apparatus (6) disposed on the top face (5) of the sliding body (2) for fastening to a sporting shoe (7) of a user (8) in such a way that the fastening can be released as and when necessary, a circulating belt (13) having a first segment (14) for establishing a relative motion between the sliding body (2) and the ground (12) and a second, returning segment (15), as well as a drive apparatus (17) and at least one first deflecting apparatus (18) for the belt (13). The first segment (14) is disposed next to the bottom side (3) of the sliding body (2) and the second, returning segment (15) is disposed next to the top face (5) of the sliding body (2). At least the majority of the length (9) of the sliding body (2) is surrounded by the circulating, intrinsically closed belt (13). By means of this design, a user can be supported with regard to his advancing movement, in particular the overcoming of ascents and mountain routes can thereby be made easier, such that the body force or performance capacity to be applied by the user can be lower.

The present invention discloses a personal transportation device comprising a frame structure, a board platform, and a propulsion assembly. The board platform mounted on an upper portion of the frame to support a standing rider. The propulsion assembly mounted to a lower portion of the frame comprises an axle assembly, a first wheel assembly, a second wheel assembly, an endless drive unit, a drivetrain assembly, and a suspension system. The axle assembly comprises a first axle and a second axle opposite to the first axle. Each axle comprises a pair of wheels. The endless drive unit is engaged with the wheels to rotate in response to the wheel rotation to propel the device. The drivetrain assembly coupled to the axle assembly comprising a motor assembly. Each motor transfers rotational energy to the wheels. A suspension assembly connected between the frame structure and wheels to enable multidimensional articulation and absorb vibrations.
