CARROLL GARDENS — Squeaky wheels will get new Citi Bike stations.

The bike sharing service wants input on where to add docking locations in South Brooklyn as it continues an expansion to double its size over the next two years, City Councilman Brad Lander announced recently.

Residents can tell Citi Bike where they want the new locations in Cobble Hill, Carroll Gardens, Gowanus, Park Slope and Red Hook using an online map and feedback form.

The bike sharing service plans to expand into those neighborhoods in 2016, according to Lander.

"It's going to be a huge plus for the neighborhood," said Eric McClure, co-founder of Park Slope Neighbors. “I've been a Citi Bike member since the launch and it frustrates me that the closest I can get to a bike is at Dean Street and Fourth Avenue."

Though it's a hotbed of cycling enthusiasts, most of Park Slope and other South Brooklyn neighborhoods were left out of Citi Bike's initial 2013 rollout. Last fall, Citi Bike announced plans to grow its fleet of bikes from 6,000 to 12,000.

Citi Bike's goal is to place stations so that they are about a five minute walk from one another, according to Lander.

New stations were installed in eastern Bed-Stuy last week, and they've recently rolled into Long Island City, Williamsburg, and Greenpoint. The Upper West Side and Upper East Side are also slated to get new docking stations.

The map where users can suggest locations shows many requests for docking stations near transit hubs such as the F train stops on Carroll Street and Bergen Street. Some have also asked for Citi Bike locations inside Prospect Park.
