The Monthly Membership is great for people looking for month-to-month flexibility. It includes 30 days of unlimited Hubway access.
When you become a member for $20 per month, you'll get a key that unlocks thousands of bikes around Boston, Brookline, Cambridge and Somerville. You can even ride the very same day you sign up, using your credit card at a station kiosk.
You can take as many rides as you want while your membership is active, and the first 30 minutes of each ride are included in your plan. See usage fees for longer rides.
