The city's new bike share program sponsored by Citibank is being launched today. New Yorkers have access to thousands of blue bikes at 330 stations throughout southern Manhattan and parts of Brooklyn. The 45-pound bikes feature three gears, a rack and strap on the front to store bags and lights that are activated when the wheels spin, according to Citi Bike's website. Bike share membership costs $95 per year, $25 per week or $9.95 per day for unlimited use provided that each ride is less than 45 minutes, according Citi Bike. While many welcome the idea of the accessibility of bikes for rent, critics worry that the program may lead to an increase in accidents. Pictured above are citi bike stations in front of Grand Central Terminal and at 51st Street and Lexington Avenue.
