Electric bikes sell briskly as gas prices climb

Desire for green travel also driving many to this form of transport

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.

Official sales figures are hard to pin down, but the Gluskin-Townley Group, which does market research for the National Bicycle Dealers Association, estimates 10,000 electric bikes were sold in the U.S. in 2007, up from 6,000 in 2006.
