Using the Back-Roller Core pannier is easy. First, attach it securely to your bike. For daily commutes or short trips, you can just throw in your essentials like your wallet, phone, and keys. For longer bike tours, you can pack clothes, snacks, and other necessities. When you need to carry it off the bike, use the Carrying System Bike Pannier to carry it on your back. To keep your items organized, use the optional inserts. As for maintenance, it's a good idea to clean it regularly with a mild detergent and water. After cleaning, let it dry completely before using it again. Avoid exposing it to sharp objects to prevent tears. And if you're not using it for a long time, store it in a dry place.
