NBA

The National Bicycle Association (NBA), later known as the National Bicycle Motocross Association (NBMXA), was the first BMX sports sanctioning body in the United States. It was founded in 1973 by Ernie Alexander, a former motorcycle racer and promoter, in Southern California. The NBA played a pivotal role in organizing and formalizing BMX racing, introducing the first national BMX events and professional divisions2.

The NBA's influence extended across the U.S., hosting races and establishing tracks nationwide. However, by the early 1980s, the NBA faced competition from other sanctioning bodies like the National Bicycle League (NBL) and the American Bicycle Association (ABA). Eventually, the NBA merged into the NBL, marking the end of its independent operations
