NEW YORK - The long-awaited Citi Bike program has officially launched in New York City, but Bronx residents will have to leave the borough to hop a two-wheel ride.

Annual pass-holders can start riding this afternoon in Brooklyn and Manhattan, while anyone planning to use day or week passes will have to wait until June 2.

The program has caused some controversy, primarily over the placement of docking stations. Some residents say racks get in the way of garbage collection, take up parking spaces and clutter already congested sidewalks.
