That's easy. The 3 fleu-de-lys coat of arms and the rooster (not chicken) are symbols of French nobility. It's just a herald used by the bike shop. From this site: https://bonjourparis.com/uncategoris...vercingetorix/

Starting out in Lyon, he (Julius Caesar) worked his way up across the Berry, Burgundy and Champagne regions until he reached what is today Belgium. The two typically French emblems, “fleur de lys” and the rooster, are both thought to be handed down from Gaelic times.
​​​​​​Fleur de Lys coat of arms, emblem used in the past by French nobility
La “fleur de lys”, later to become a symbol of French nobility, was probably the tip of a spear used commonly by the Celts. As for the French rooster, the word “Gallus” meaning both “Gaelic” and “rooster “, when Caesar arrived, the animal was already a favourite symbol among the Celtic tribes in the north. It is still a national emblem in both France and Belgium today.

You're welcome.
