A cruiser bicycle, also known as a beach cruiser, is a bicycle which combines balloon tires, an upright seating posture, a single-speed drivetrain, and straightforward steel construction with expressive styling. Cruisers are popular amongst casual bicyclists and vacationers because they are very stable and easy to ride, but their heavy weight and balloon tires tend to make them rather slow. They are associated with the larger category of hybrid bicycles.
The bikes, noted for their durability and heavy weight, were the most popular bicycle in the United States from the early 1930s through the 1950s, and have enjoyed renewed popularity since the late 1990s.
Schwinn developed the cruiser at a time when U.S. bicycle sales had declined sharply due to the Great Depression; adults purchased few bicycles, which were seen as luxury products intended largely for sport or recreation. In response, Schwinn conceived a sturdier, affordable bicycle designed for the more resilient youth market—originally marketing the Schwinn B-10E Motorbike—which resembled a motorcycle but carried no motor—in 1933. Schwinn adapted features from the Henderson and Excelsior motorcycles his company had built during the 1920s, including a heavy "cantilevered" frame with two top tubes and 2.125-inch-wide (54.0 mm) "balloon" tires from Germany. The resulting bicycle could endure abuse that could damage other bicycles. Within two years, other bicycle manufacturers in the USA introduced competing balloon-tire bikes.
