Mike Corbin has long been an innovator in fuel economy vehicles. In 1974: Corbin begins sale of street legal electric motorcycles. Professor Charles E. MacArthur makes first electric vehicle ascent on Mt. Washington, NH using a Corbin Electric motorcycle. On June 17, 1975 a high energy density silver zinc battery was used in the Mt. Washington attempt. This super battery, with a total energy content of over 4,680 watt hours, successfully powered the Corbin designed motorcycle 8 miles to the summit on an average grade of 12%, through 99 hairpin turns, in 26 minutes nonstop. On June 18, this same winning combination made 2 nonstop trips to the summit, thus setting another record.
