In Paris, Riding a Bike Is LiberatingBeginning on July 15, thousands of bicycles became available in Paris at hundreds of self-service docking stations installed around the city by J. C. Decaux, an outdoor advertising company. Anyone, even fresh-off-the-plane Americans, can stroll over, swipe a credit card and ride away on a sturdy, well-maintained three-speed bike, a “vélo” in French. Access to the bikes is available all of the time; it's liberating, as in “liberté,” so the “Vélib” was born.
Twelve weeks after the introduction of the Vélib, 15,000 bikes have been put into service at more than 1,000 stations. In that time Vélibiens (or Vélibeurs or perhaps Vélibistes) have checked out bicycles almost six million times and ridden them an estimated 7.5 million miles.
The Vélib system is simple. You swipe a credit card in a kiosk that is located beside a row of parked bikes and purchase a one-day, one-week or one-year subscription. (The system also takes a 150-euro deposit authorization to ensure the bike's safe return.) The machine prints out a card with your code number and you enter a personal password. You tap in this code and password to unlock a bike and ride off.
