The Orbis has it all over the Segway. It’s half as big as the Segway, has easier maneuverability in tight spots and folds down for storage. It also sports a 13 mph top speed and is battery powered. Eat it Segway.
It isn’t all awesomeness though. It has some obvious balance issues. Those can be worked out though with some time and money. At the moment it’s just a concept, but a good one. It will likely come to pass, since this thing is like the hot rod of the Segway culture.
