Bicycles for rent on Nantucket Island MA
Bike shops for renting or repairing bikes are here and there, although it must be admitted there are a lot more shops selling expensive, sophisticated bikes than there are places renting simple bikes for a day's outing.
In many places old railroad right-of-ways have been turned into rail trails—perfect bike paths with level surfaces, easy curves and grades.
Among the most prominent bike trails are the ones in Cape Cod National Seashore, as well as the Shining Sea Bike Path between Falmouth and Woods Hole MA, and the Minuteman Bikeway from Boston to near Concord MA.
