Soon, Citi Bike is getting closer to living up to its name.

Maps obtained by The Post show that in the next three years, the bicycle-share program is going to double its geographic reach by placing docks in the Bronx and farther out into Manhattan, Brooklyn and Queens.

Citi Bike ridership has boomed this summer, with New Yorkers routinely taking 75,000 trips in a day. But the program’s coverage remains limited to Manhattan up to 130th Street and sections of Brooklyn and Queens near the East River.

By the end of 2023, new bike-share stations will pepper Harlem, Hamilton Heights, Sugar Hill, Washington Heights and Inwood in Manhattan; Mott Haven, Melrose, Port Morris, Highbridge, Claremont, Morrisania, Longwood, Concourse and Mount Eden in the Bronx; Bedford-Stuyvesant, Brownsville, Crown Heights, Prospect Lefferts Gardens, East Flatbush, Sunset Park, South Slope, Windsor Terrace, Prospect Park South and Kensington in Brooklyn; and Sunnyside, Maspeth, Elmhurst, Jackson Heights and Corona in Queens.

“Finally, the city in Citi Bike is going to mean something,” Bronx Borough President Ruben Diaz Jr. told The Post.

The program, owned by Lyft, is forking over $100 million for the expansion. It will also add bikes to the existing coverage area, bringing the total size of the fleet to 40,000.

Last year, the city tested “dockless” bike-share systems in city neighborhoods. But docked Citi Bikes get nearly three times as many riders per bike compared with their dockless counterparts, according to city officials — in part because they are connected to a larger network.

New Yorkers had mixed reactions to the planned expansion.

“There’s a lot of overweight people up here, so it’s good to get them riding and moving around,” said Miguel Vazquez, 25, of the Bronx. “I love the idea that they’re providing this service to lesser privileged communities.”

But Ben, a New Jersey-to-Tribeca commuter who declined to give his last name, was not so thrilled.

“There’s less parking spots, narrower streets,” he said.

An annual Citi Bike subscription costs $169. New Yorkers and tourists can also purchase single rides for $3 via the Lyft app.

“This expansion will help us build a more fair and equitable city for all New Yorkers,” said Mayor de Blasio. “Even more communities will have access to this low-cost, sustainable mode of transportation.”
