The most convenient way of carrying anything on a bike is with pannier bags. These are the bags which are attached to either side of the rack on the front or rear of a bike allowing you to carry things without a backpack. Providing you have suitable racks to place the panniers on, the bags can be loaded and securely fastened allowing you to ride without worrying about anything flapping about or falling off. They are made from heavy duty nylon or similar with more specialist bags being fully waterproof and more robust for longer adventures. Bags are available as single, double or even triple, the top bag goes over the top of the rack, in many different sizes and styles to suit all needs and budgets.
