Most of the stations of Hubway, the region’s bike-share system, will reopen April 17 after many closed for the winter. Thirteen stations along or adjacent to the Boston Marathon route will remain closed until after the April 20 race. Hubway began operating in the region in 2011 and now includes 140 stations and more than 1,300 bikes in Boston, Cambridge, Brookline, and Somerville. Hubway regularly shuts down most of its operations for the winter, when riders are less likely to take advantage of the system. The system closed most of its stations in November, though for the past two winters, Cambridge has kept most of its stations open. This past winter, Boston also started keeping some stations open. Officials from Somerville have also said they are considering whether to keep stations open year-round.
