Using these Blackburn Local pannier bags is easy. First, attach them to your bike's standard rack. You can put your daily essentials or travel gear inside the main 26 - litre space. Use the exterior pocket for quick - access items like keys or a phone. For extra safety, attach your flashers to the loops on either side. When you're off the bike, you can carry the bags with the removable shoulder strap. As for maintenance, keep the bags clean by wiping them with a damp cloth. Avoid exposing them to harsh chemicals. If there are any small tears, you can use a repair kit to fix them. Also, store the bags in a dry place when not in use to prevent mold and mildew.
