The company briefly (1978–1979) produced a bicycle styled after the California mountain bikes, the Klunker 5. Using the standard electro-forged cantilever frame, and fitted with five-speed derailleur gears and knobby tires, the Klunker 5 was never heavily marketed, and was not even listed in the Schwinn product catalog. Unlike its progenitors, the Klunker proved incapable of withstanding hard off-road use, and after an unsuccessful attempt to reintroduce the model as the Spitfire 5, it was dropped from production.
