The board is 25 inches long and has clay wheels. Roller Derby was one of the earliest mass producers of skateboards. In 1964, the company began making surfboard-shaped boards to tap into the growing “sidewalk surfing” craze, producing models that resembled the surfboards of the era. As a product of the early skateboarding boom, the Aerflyte board reflects the “sidewalk surfboard” design characteristics of the time. These boards often had a flat, often wider wooden deck and single-action trucks, which allowed for deep, sweeping turns that imitated surfing on asphalt. While not as agile as a modern surfskate, the Aerflyte’s design was intended for the smooth, carving motion that defined early sidewalk surfing, rather than the more technical, trick-oriented style of modern skateboards.
