Early success of Hub bike sharing surprises even program’s backers »

In its first month, Boston’s European-style bicycle sharing-system pedaled past expectations, attracting riders more than twice as fast as similar programs in Denver and Minneapolis.

As of Aug. 28, the one-month mark, the program known as Hubway had attracted 2,319 annual subscribers and witnessed 36,612 station-to-station trips. At its current clip, the system is on track to surpass 100,000 rides before Halloween.
