1989 Sbarro Orbital Wheel

Sbarro, the Italian inventor/ engineer who designed and built the first working hubless wheels (patent now held by Globeholding, in Geneva). Sbarro has built many working rim rider vehicles and at least two working rim rider motorcycles. A rim rider wheel has no center hub, just a clean empty hole. The Wheel itself is, in essence, the outer race of a very large bearing.
