Leisure equipment is disclosed which permits an experience of fully controlled loop-the-loop rotary motion with a wheeled vehicle. The leisure equipment comprises a frame structure with a trough-shaped wheel track, an axis of rotation and at least one rotating arm with one wheeled vehicle each. The trough-shaped wheel track is curved so as to form a closed contour. The axis of rotation is contained within this contour. At least one rotating arm is rotatably supported on this axis of rotation. At the rotating arm a wheeled vehicle is fastened which is adapted to be guided in the wheel track. The wheeled vehicle is pressed into the wheel track by a pressing device acting on the rotating arm. In this way a contact of wheel track and wheeled vehicle exists in every point of the wheel track. With the wheeled vehicle of the leisure equipment, a rider can perform loop-the-loop rotary motions or revolutions during which he retains full command of the motion at all times.
