Among rows gadgets, an electric motorcycle turned heads at CES, backed by the claim that it produces zero emissions (although overall environmental impact depends on the electricity source), can travel 40-60 miles on a charge at speeds up to 60 mph, and can be charged to 80 percent of battery capacity in two hours using a standard 110-volt outlet. The Vectrix also features an onboard charger and cord, and it uses regenerative braking to extend range by up to 12 percent. Vectrix U.S.A. claims an operating cost for its self-named bike of just two cents per mile.

The manufacturer says the two-wheeled green machine is easy to ride, with a low center of gravity and planetary gear system that doesn't require shifting going forward. There is a reverse gear to make parking easier.

With nickel-metal-hydride batteries, Vectrix says to expect a 10-year battery life, based on driving 5,000 miles per year. Capable of carrying two riders, the Vectrix is road legal in all 50 states. On sale since late 2007, dealers are now operating in seven states with plans for nationwide availability. Some of the first units went to the New York City Police department, who put several into a testing program. 

The price? $11,000, but Vectrix says some tax incentives may be available.
