The Schwinn Whizzer: A Comprehensive Overview
The Schwinn Whizzer motorized bicycle is a fascinating piece of American motorcycling history, combining the classic Schwinn bicycle frame with a Whizzer motor to create a unique and popular mode of transportation. Here is a comprehensive overview of its history, design, and impact:
Historical Background
The Whizzer motorized bicycle engines were first introduced in 1939 by the Breene-Taylor Engineering Corporation, a Los Angeles-based manufacturer of aircraft parts. The concept was to provide a motor that could be attached to a standard bicycle, thus creating a motorized bicycle. Initially, these engines were sold as kits for consumers to assemble themselves. Despite a slow start, with only about 2,500 units sold by 1942, the Whizzer gained popularity during World War II as an efficient way for defense workers to commute.
In 1948, Whizzer introduced its first pre-assembled motorized bicycle, the "Pacemaker," which was priced at $199.50. This model featured a 138cc, 3 horsepower engine and was followed by other models like the "Sportsman," which included additional features such as a kick starter and drum brakes. The production of Whizzer engines continued until 1965 when they ceased due to increasing competition in the market.
Design and Features
The Schwinn Whizzer motorized bicycles were notable for their robust design, largely attributed to the Schwinn Cantilever frame, which was sturdy enough to handle the additional weight and power of the motor without requiring significant modifications. The Whizzer motor kit included an air-cooled, four-cycle engine that allowed the bicycle to be powered by the motor, making it a practical and economical mode of transportation during its time.
In 1947, Whizzer began producing a proprietary brand of motorbikes that closely resembled the Schwinn frame. However, to avoid legal issues due to patent similarities, production of the motorbike frames was passed to Schwinn, resulting in models like the Schwinn-built WZ, which featured adaptations like a notched rear fender and frame for belt clearance, thicker spokes, and a front drum brake.
Legacy and Modern Revival
After ceasing production in 1965, the Whizzer brand experienced a revival in 1997 with the introduction of an improved version of the original motorized bicycle, now pre-assembled on a Schwinn-style frame. This modern iteration maintained the nostalgic appeal of the original while incorporating technological advancements. Despite this revival, the Whizzer company has been on a hiatus from production since at least 2009, though replacement parts and accessories remain available for enthusiasts.
The Schwinn Whizzer represents a significant chapter in the history of motorized bicycles, combining innovation with practicality. Its legacy continues to be celebrated by vintage bicycle collectors and motorbike enthusiasts alike.
