The Whizzer bolt on bicycle engine was originally created by an aircraft parts manufacturer so it is fitting that Clymer found one on display at the 2013 Heart of America Motorcycle Enthusiasts vintage motorcycle rally held at an airport.
Clymer Girl and the crew didn’t have to go far to attend the HoAME show and rally, as it was just up the road at the Kansas City Airline History Museum in the Downtown Airport. The show was packed with classic vintage and antique motorcycles including British, German, Japanese, Italian, and American makes, all on display. Manufacturers represented include Honda, Yamaha, Suzuki, BMW, Harley Davidson, Vincent, Triumph, BSA, Norton, Brough Superior, Indian, Cushman, Vespa, Laverda, Puch, Lambretta, MV Augusta, Ducati, Matchless, Zundapp, Moto Guzzi, AJS and more. There were 100% perfect restorations, well worn bikes daily riders, full-on customs, cafe racers, choppers, bobbers, dirt bikes, road racers – any type or style of motorcycle you could image. Also on display were vintage propeller driven passenger planes, including a Douglas DC-3, a Martin 404, and right outside the hangar was a 1958 Lockheed Super Constellation.
Way back in 1939 the Breene-Taylor Engineering company first introduced their clamp-on motor unit for installation in any bicycle frame. They sold less than 3,000 units before the start of WWII, but wartime shortages of fuel and everything else gave them a real boost. The government allowed them to continue selling their kits, and workers dealing with fuel rationing discovered the joys of more than 100 miles to that gallon of gas. After the war they really hit their stride, selling Pacemaker motorcycles, based on their motor and a dedicated bicycle frame. By 1965 the invasion of low cost Japanese motorcycles from Honda and the like spelled the end for Whizzer. Though there was a revival in the 1990s, it had fizzled by 2009.
