Anderson is the younger of what was one of the most potent sibling combinations that bicycle motocross has ever seen. Only the Pattersons, Brian and Brent, whom Richie raced with on the same factory team for seven years, had more titles between them and were more dominant in BMX. His older brother Ronnie Anderson, whose amateur career Richie overshadowed, would become National number one pro with the American Bicycle Association (ABA) and the United Bicycle Racers (UBR) an achievement Richie never achieved after he turned professional.
