Definition
A pannier is a basket, bag, or similar container attached to the side of a bicycle or animal (like a horse or donkey) for carrying goods. It's a convenient way to transport items while cycling or traveling. Think of it as a bike's backpack. Unlike a backpack worn on your back, it distributes weight on the bike. It's commonly used for touring, commuting, and shopping. It can also refer to a frame used to expand a skirt.
