A recreational toy wheel vehicle comprises a generally annular outer wheel member having an outer peripheral rolling surface and a generally smooth inner peripheral surface area defining a generally circular, axially extending interior cavity. A carriage member has a passenger carrying seat and a series of generally smooth rib members which contact the generally smooth inner surface area of the wheel member. The generally smooth inner surface area of the wheel member and the generally smooth rib members are fabricated of materials which minimize the coefficient of sliding, or kinetic, friction therebetween. Relatively frictionless or gliding contact between the two materials thus occurs, so that the carriage member is supported in a non-rotating position within the interior cavity during rotation of the outer wheel member on the rolling surface.
