Inspired by its smaller neighbors, Paris launches the 6,000-bike Vélib’ system and the worldwide movement toward bike-share is off and running. By 2015, Paris will have a total of 18,000 bikes.
 In Spain, Barcelona’s Bicing is the first entry in what quickly becomes a nationwide boom in that country. By 2013, 132 Spanish cities will have bike-share, making Spain a global leader in the phenomenon.
