The Whizzer was probably responsible for getting more people into motorcycling than any other vehicle. They first came in a kit that you could mount on your standard bicycle – usually a Schwinn like this one. The kit sold for about $100. Whizzer was only one of two consumer motorized vehicles made during WWII (Cushman was the other). In 1948 Whizzer started selling complete bikes but had to battle Schwinn about patent rights. The small motorcycle killed the Whizzer and they went out of business in 1965, although new Whizzers (made in Taiwan) are now for sale for $2,000. Approximately 200,000 Whizzer engines were made, almost all now in junkyards.
