6,000 bikes were added to city streets Monday as the city launched what it called the largest bike share program in the country.

At more than 300 bike stations in Manhattan and parts of Brooklyn, New Yorkers may now take bikes for quick rides. Only those with $95 annual memberships can ride during this first week of the program.  The city says bike shares are supposed to compliment the subway system and fill in the gaps where train lines are missing.  

By mid-afternoon, a station on the east side of Washington Square Park was full of bikes while further south near Spring and Sixth Avenue the station was empty.  

The bike share program took 3 years to implement. Eventually, it's supposed to include 10,000 bikes at 600 stations.
