Balance bike racing grew out of BMX start practice, where riders ready is the classic call before the gate drops, adapted here for toddlers on pedal-less bikes who start by pushing with their feet. Events for two to five year olds made the format familiar to families, with parents filming the shy line-up and the burst of crowd cheering at the start. Online, the clip is shared as a wholesome sports sound for first races, school sports days and playful family competitions, long after the original race recording.
