Pannier

A pannier /ˈpæniər/ is a basket, bag, box, or similar container, carried in pairs either slung over the back of a beast of burden, or attached to the sides of a bicycle or motorcycle. The term derives from a Middle English borrowing of the Old French panier, meaning 'bread basket'.

Traditional panniers for animal transport are typically made of canvas, leather, or wicker. Modern panniers may be rectangular boxes of hard-sided plastic. Panniers are loaded in such a manner as to distribute weight evenly on either side of the animal. For horse packing, and when carrying particularly heavy loads on other animals they are supported by a pack saddle to distribute weight more evenly across the back of the animal. In some cases, additional items are placed on the back of the animal, between the panniers.

There are many styles of bicycle panniers. Touring panniers are usually sold in pairs, intended to hold enough equipment for self-sustained tours over days or weeks. The most common setup is to use a pair of smaller panniers (10 to 15 liters each) mounted on a low rider and a pair of larger ones on the rear carrier (20 to 30 liters each).

Commuters who bicycle have pannier options designed to hold laptop computers, files and folders, changes of clothes or shoes and lunches. There are also panniers that convert to backpacks or shoulder bags for easier carrying when not on a bicycle. Since the movement against disposable shopping bags emerged, many panniers are made easily detachable from the bike, to allow using them for shopping bags. Some cyclists create makeshift pannier bags out of grocery bags, grocery baskets, garment-bags, convertible backpacks, and various multi-purpose bags as alternatives to purchasing a commercial pannier.
