Remember when it was anorexic models and mountain bikes? We know Kate wouldn’t have made it a mile or so without any calories to burn in her emaciated body or muscles to get over the slightest hill. The black and white, the silhouette of a body in a bikini likely made men want to buy a Manitou bike and women want to not eat.
I don’t remember seeing models on bikes during the heroin chic look, but a Tumblr blog will likely find it.
