If a company makes as bold a statement as "we reinvented the wheel" when introducing a gadget you know we've gotta check 'em out and see what the hubbub's about. Well, at the International Toy Fair in New York, Inventist has introduced its "Solowheel" product, which is essentially a self-balancing unicycle for personal mobility. We've seen similar products before, but the convenient carrying handle and lack of seat make it decidedly more portable than the competition.
