A recreational device includes an outer hoop to which a generally axially disposed hub is secured by radial spokes. The hub includes a discoid portion and a generally cylindrical wall defining a recess so that the device can be spun on the tip of a stick. An axial hole in the hub allows two of the devices to be mounted on a shaft to provide a pair of wheels while, by detaching the hub and the spokes from the hoop, the device is converted into a conventional trundling hoop. By the use of generally trapezoidal vanes having airfoil configurations as the spokes, the device can be caused to fly through the air when spun from the tip of a stick or, by inverting the device, it tends to remain on the tip of such a stick when it is spun thereon.
