The City Fix reports that NYC hired Alta Bicycle Share "to operate and launch an initial system with 10,500 bicycles and 600 stations around Manhattan and Brooklyn, which will mark the first phase of the system. City officials plan the system will later expand in two additional phases to cover the entire island of Manhattan and large portions of Brooklyn, Bronx and Queens."
The city is also asking Manhattan's citizens to help them choose the locations for a planned 600 bikeshare stations:
"Those interested in participating can suggest a location for a possible station through a site built for New York City's newest transit option."
