Louis Bobet was born one of three children above his father's baker's shop in the rue de Montfort, Saint-Méen-le-Grand, near Rennes. His father gave him a bicycle when he was two and after six months he could ride it 6 km. Bobet's father was also called Louis and the son was called Louison - little Louis - to avoid confusion The ending "-on" is a diminutive in French but outside Brittany Louison refers more usually to a girl. He was known as Louis in his early years as a rider, even as a professional, until the diminutive Louison gained in popularity.
