I'm unconvinced about the mini front wheel, but the back wheel... hubless wheels are way cool! There's a photo of a working prototype if you follow the link. Lunart Hubless, Lunart Bicycles, Bicicletas Con, Dyson, Luke Douglas, One Bicycle, Cycling Lunartic4, Bici Con, Lunart Cycling
Lunartic Bike with Hubless Rear Wheel
The Union is a folding cycle that you can carry easily in public transport systems like buses and trains. Folded up, it’s more like backpack that doesn’t weigh you down. This 8-inch folding bicycle slams down in a jiffy and its most defining feature is that it combines the stem with the headlight and the saddle with taillight, for better visibility and safety.
