Boston's bicycle sharing program, which just opened for its fourth season, is thriving at a time when similar programs in other cities are struggling financially.

The Boston Globe reports that Hubway opened last week with a positive financial prognosis, a fresh contract between the city and bike-share operators, an expectation that the system will continue turning a profit, and plans for 10 new stations.

Montreal's bike-share program filed for bankruptcy in January. Last month, reports surfaced that operators of New York's program had asked for tens of millions of dollars in aid from the city.

Some have attributed Hubway's success to more conservative choices, closing for winter and launching with a compact system that spread cautiously, as well as it dependence on both public and private money.
