NEW YORK -- When Honora Wolfe and her husband moved to the outskirts of Boulder, Colo., she wanted an environmentally friendly way to commute to her job as a bookshop owner in the city, according to The Associated Press.

Wolfe, 60, found her solution about a month ago: an electric bicycle. It gets her to work quickly, is easy on her arthritis and is better for the environment than a car.

"I'm not out to win any races," she said. "I want to get a little fresh air and exercise, and cut my carbon footprint, and spend less money on gas. And where I live, I can ride my bike seven months out of the year."

The surging cost of gasoline and a desire for a greener commute are turning more people to electric bikes as an unconventional form of transportation. They function like a typical two-wheeler but with a battery-powered assist, and bike dealers, riders and experts say they are flying off the racks.
