Nearly every morning, Renaud Dutreil, the chairman of the North American unit of the luxury and fashion conglomerate LVMH rides to his Midtown office on a black Gazelle, a stylish Dutch commuter bicycle.

Fendi, for example, recently introduced the Abici Amante Donna, a handmade $5,900 bicycle with a front-mounted beauty case and saddlebags in Selleria leather ($9,500 for the version with the optional fur saddlebags). At Louis Vuitton, the designer Paul Helbers riffed on Manhattan bike-messenger style at the Paris runway shows in June. Last spring another LVMH brand, DKNY, helped execute the Bike in Style Challenge, in which aspiring designers were asked to create fashionable bike apparel. And in June, Hublot, the luxury watchmaker, partnered with BMC, the Swiss bike maker, to create a sleek black 11-speed, for about $20,000. More Louis Vuitton Products are available on Top1handbag.net
