Dorchester now has its first Hubway station, a 15-bike facility next to Robert E. Ryan Playground off Dorchester Avenue in Savin Hill. The new station is one of 15 that either have been or are scheduled to be installed as part of the city’s latest expansion of the popular bike sharing program.

It is the 145th Hubway depository in Greater Boston, including those in Brookline, Somerville, and Cambridge, according to Hubway. Once all currently planned stations are installed, the city of Boston will be host to 108 stations holding 1,100 bikes, according to the mayor’s office.

“Whether your mission is to visit family or local businesses, get to work, or just enjoy a ride, Hubway is a convenient and economical option for traveling around the city,” said Boston Transportation Commissioner Gina Fiandaca. “I encourage anyone who isn’t already using the service to give it a try.”

David Cotter, Dorchester liaison for the Mayor’s Office of Neighborhood Services, updated Columbia-Savin Hill Civic Association members Monday about the new Ryan Playground station. Another location at the Savin Hill MBTA station is on hold pending approval, and “unfortunately, it’s probably not going to happen this year,” Cotter said.

A potential location on Sydney Street across from the Savin Bar and Kitchen has not been confirmed; public comment on the location is open until next Monday, Cotter said.

The expansion will include the first Hubway locations in Brighton, with more to come in Dorchester, Roxbury and Charlestown. The system is reliant upon a reasonable distance between hubs, so new stations will be rolled out incrementally.

“Hubway is a healthy, affordable option for Boston residents to get to school or work, and I am thrilled we are able to expand it to even more neighborhoods,” said Mayor Martin Walsh. “We will continue to work with our community partners so that all of our residents have access to a diverse range of transportation options.”
