Uno Cycle

Ben Gulak was only 16 when, after visiting smog-choked China, he dreamed up this eco-conscious transportation solution. But the two-wheeled concept never made it to market. The inventive Canadian has since enrolled at MIT and developed decidedly more aggressive recreational products, such as the DTV (Dual Track Vehicle) Shredder, which looks like the love child of a Segway and a tank. Inspired by the success of Bombardier (the company behind the BRP Can-Am Spyder), Gulak says his Boston-based BPG Werks has presold 5000 Shredders. Still, we wouldn't be surprised if his Uno concept somehow reappears down the line. We never forget our first love, do we?
