This complete kit converts most 26-inch mountain bikes and 700c road bikes into an electric-powered bike, providing an 18- to 20-mile range on a single six- to eight-hour charge, with top speeds of 16 to 18 mph. The electric motor does not eliminate the normal functions of the bicycle, leaving gears and freewheeling abilities unaffected. It is powered by dual 12-volt, 12-amp hour, 12-amp sealed lead acid batteries that mount to most frames. The suggested retail price is $899. Mark Thivierge Agencies: 800-607-7907.
