A wheel skate device having a foot platform, a frame, and a ring-shaped wheel. The user operates a pair of the wheel skate devices while standing with one foot on each foot platform. The foot platform is movable between an in-use position and a stowage position. In the in-use position. the foot platform interlocks with the frame and can be secured with a locking pin. A pair of the wheel skate devices in stowage position can be connected together as a single unit using a connecting piece, which may have an attached strap for carrying or hanging. A mechanism which limits the wheel to rolling in only one direction, and an elastic band linking two wheel skate devices together to prevent the user's feet from accidentally moving too far apart, are useful learning aids.
