All bikes must have three number plates attached to the bike, one on the front and one on each side. Number plates should have numbers only, no letters.  Numbers must be black on white background, black on yellow, or white on black.  Numbers must be highly visible so they can be seen easily by the scorekeepers.  If the scorekeepers cannot see the number, the rider will not be scored.
