Despite Biomechanics, I can think about the so called "surplace", or "track stand", often practiced by pistards.
Citing Wikipedia:
*The track stand or standstill is a technique that bicycle riders can use to maintain balance while their bicycle remains stationary or moves only minimal distances.
[...]
The term originated from use of the technique by track cyclists prior to starting, or as a tactic in track sprinting whereby riders will initially ride very slowly and maneuver across the track in an effort to get their rival to take the lead so that they can then draft (or slipstream) behind, conserving energy for the final sprint.
Other types of cyclists also use the technique. Commuters and bike messengers use it while stopped in traffic, especially at red lights, mountain bikers use it in difficult terrain to determine a path and BMX cyclists use it in preparation for tricks.
