Living Social deal, bike tune-up. I used Back Bay Bicycles last year and I think they did a good job although they took off my chain guard and never put it back on lol but I think they made everything nice and tight.
A meetup for people who would like to occasionally take short, leisurley bicycle rides in and around Boston. Rides will generally be on bike paths, possibly including some easy unpaved trails. They will last an hour or two and we will travel at an easy pace. The ride will usually be followed by a lunch or dinner, which is optional.
