All eras from the 1940s to the 1980s are represented. There are even two snow cycles manufactured by major car companies, Porsche and Chrysler. Porsche’s Ski-Bob snow bike was apparently a limited edition vehicle intended for ski slope rescues. Chrysler’s foray into snow motorcycles was much more intense, as they built a snow cycle in the late 1970s powered by their own 2-stroke racing kart engine in an attempt to market snow motorcycles on a major scale. After converting part of a Chrysler Outboard plant in Wisconsin into a full-fledged assembly line, Chrysler built a reported 28,000 Sno-Runners from 1979 to 1982 before halting production. This undoubtedly was the largest volume production of snow motorcycles in history.
