We stepped off the ferry and made the easy one-block walk to Young's Bicycle Shop. We were greeted promptly, and while one staffer got our information another pulled out some bikes for us so that by the time we swiped our credit card they had two bikes ready to go. They gave us a short explanation of the bike's features and some suggested routes to try. This was only shoulder season, but I was impressed with how quickly and efficiently they got us out riding given that we walked in without a reservation. The bikes themselves were spotlessly clean and appeared (and felt) very well-maintained. I'm not sure what their entire inventory consists of, but we got a couple of nice Cannondales with Shimano twist-style shifters. Locks, helmets, and maps were all included in the rental. One of our bikes had a basket and both had a rack and bungee cord. We had no problems at all with the bikes during a long day of biking across Nantucket, and returning the bikes was just as fast and painless as checking them out had been. I have no hesitation in recommending Young's.
