There are 27 miles of bike paths (purists call them 'multi-use' paths, because you can walk on them too.) There are plenty of opportunities to rent bikes and mopeds (mopeds must stay on the street). One of our favorite island places to rent bikes and stuff is Billy's Bikes on Periwinkle Way. Billy also rents Seqways, those two-wheel stand up personal transporters. He includes a familiarization session before you Segway on your own. Other bike rental firms include Finnimore's and The Bike Route.
