Panniers are bags or containers designed to be attached to the sides of a bicycle, allowing for easy transport of items. They are commonly used by cyclists for commuting, touring, or shopping, providing a convenient way to carry belongings without the need for a backpack. Panniers come in various sizes and materials, often featuring waterproof designs to protect contents from the elements. Typically, panniers are mounted on a bicycle rack located above the rear wheel, although front panniers can also be used. They can be secured with hooks, clips, or straps, ensuring stability during rides. Many cyclists appreciate panniers for their practicality and ability to distribute weight evenly, enhancing comfort while cycling.
