Citi Bike is a privately owned public bicycle sharing system serving the New York City boroughs of the Bronx, Brooklyn, Manhattan, and Queens, as well as Jersey City and Hoboken, New Jersey. Named after lead sponsor Citigroup, it was operated by Motivate, with former Metropolitan Transportation Authority CEO Jay Walder as chief executive until September 30, 2018, when the company was acquired by Lyft. The system's bikes and stations use technology from Lyft.
