Australia has been glued to the cycling at the Rio Games. And while we’ve been incredibly proud of the way our cyclists have represented us, there’s one burning question that everyone has been asking.
Why is there a guy on an electric bike riding around the velodrome!?
It’s simple really. The guy on the motorbike sets the pace at the beginning of the Keirin. The bike is known as the derny, and the rider leads the pack of cyclists for the first five and a half laps of the event.
The rider on the derny gradually brings the competitors up to 50km/h before releasing them for the final two and a half laps. The cyclists then sprint to the finish as fast as they can.
See it all in action in the video below.
