The basics for any bike ride include water, snacks, sunglasses, windbreaker, cell phone, camera, pump and map. If you're cycling in summer, add sunscreen and insect repellent. If you're biking in winter, wear proper cold weather clothing. If you plan to ride for more than a few hours, don cycling shorts and gloves and pack a mini toolkit and spare inner tubes, one for each bike. (Novice cyclers take note: bike tools are useless if you don't know how to use them.) Families cycling with infants and tots should include the contents of their diaper bag. Pack your handlebar bag as you would a carryon. Fill it with things that require quick access such as money, travel documents, camera, paper, and pen. Pack spares and tools in your seat wedge or seat pack. Don't over pack your saddlebags or panniers and be sure to distribute the weight appropriately. - Bike clothes are quick dry; they can be rinsed at night and worn the following day. Kids can't carry as much weight as adults. Riding a lopsided bike is truly hard work.
