panniers sometimes called bike bags are luggage bags for your bicycle. These panniers can be used for long distance bike rides and bike touring or regular bike commuters going to the office. These bags can carry clothing, bike gear, laptops, cameras, bicycle parts and equipment. Most of the bike panniers on the market are water resistant for most normal conditions. For extreme waether there are bike pannier rain covers for additioal protection. These bike panniers attach to the bicyhcle using the bike rack over the back wheel. When stopped these panniers can be carried like luggage and many include handles. These bags can hold clothes, maps, equipment, tools, food and even electronics safely and securly. Most are strongly water resistant and some are waterproof. You can add waterproof covers to these bags as well. Our biking group has actually gone through a HURRICANE with torrential rain for hours and everything came through dry and safe.
