Panniers are bags or containers that attach to the sides of a bicycle, making it easier to carry items while riding. They are commonly used by cyclists for commuting, touring, or running errands. Panniers come in various sizes and styles, allowing riders to choose the best option for their needs. These bags are typically mounted on a bicycle rack and can hold groceries, camping gear, or personal belongings. Many panniers are waterproof, ensuring that your items stay dry during rainy rides. They are a practical solution for anyone looking to transport goods without the hassle of a backpack.
