Summer’s warmth is gone and along with it goes Boston’s bicycle share program. The city is in the process of shutting down the Hubway bicycle system station-by-station. 

At the moment, the 10 Back Bay stations are still online, but citywide, 12 stations were taken offline last week, according to a schedule on the Hubway’s website. They include: Andrew Station,Brigham Circle, Charlestown - Main St/Austin St., South Bay Plaza, Washington/Lenox, Washington/Waltham, Aggannis Arena, Allston Green District, BU Central, Buswell/Park, Overland/Brookline, Yawkey Way/Boylston.

Last year, the entire system was taken offline by Dec. 1. The site provides a map for Hubway stations currently active, out of service, planned and new.

The bikes are estimated to return in March, weather permitting.

The Hubway has around 105 stations scattered in and around the metro Boston area, 72 of which are in Boston.
