Segway has developed variations of thier two-wheeled personal vehicle, but recently, with the help of GM, Segway has unvieled an electric-powered two seater called the Puma. It can reach a top speed of 35 mph, and can travel 35 miles before needing a recharge.

Larry Burns, vice president of research and development for GM, said it would cost about 35 cents to charge the Puma抯 lithium ion battery system ?essentially a larger version of the power system for the Segway Personal Transporter.The Puma balances on two large wheels while driving. For safety, it employs two sets of wheels in the front and back ?similar to drag-racing vehicles ?to prevent it from tipping over. When it parks, it rests on the front set of wheels.

This is definitely something that would be used in urban areas. What better then to have an eco-friendly vehicle that can fit tightly in parking spaces.
