"Ever see Audrey Hepburn on a bicycle? No, me neither. Catherine
Deneuve? Nope. The very notion of either of them, surely two of the
most elegant women the world has ever known, getting into the gear and
clambering on board a bike is a full-frontal assault on beauty."
Roslyn Dee, columnist, Irish Daily Mail, February 2nd 2008
In fact, Audrey Hepburn was pretty much born on a bike. She lived in the Netherlands during part of the Second World War and rode her bike for the Dutch resistance: "I stuffed [illegal leaflets] in my woollen socks in my wooden shoes, got on my bike and delivered them."
