Accepted Answer

Both are participation classes for ages 2 to 7 (not scored or timed). Sprocket Rocket riders use 18" or 20" bikes, and Sprocket riders cannot ride up into competitive categories. Mini Wheelers use a 13" maximum bike.

No pedals or cranks. Pit bikes can be used but must have cranks removed and not exceed 88.9 cm.

AusCycling recommends a steel or alloy frame.
