Powered by two rechargeable batteries, it will cost about $8,000 but offers a much lower per-mile cost than just about anything this side of a bicycle. Extra batteries can be carried and swapped in as necessary for a longer range and recharge times are 4-6 hours when you get back to the station. It's a bit beefier and more authoritative looking than a Segway, and with a front wheel, a little more stable, as well. And it's green to boot. The zero-emission vehicle even uses LED lighting to minimize battery usage. T3 motion offers a range of similar vehicles customized for military, personal security and law enforcement applications.
