Using this pannier bag is a breeze. First, find a suitable rear rack on your bike. Then, use the rubber - coated hooks and bungee attachment to secure the bag to the rack. Make sure it's firmly attached before you start your ride. When packing, you can use the 13 - litre capacity to fit all your essentials like books, work files, or shopping items. The light mount is great for attaching a bike light, especially if you're riding at night. The reflective print adds an extra layer of safety by making you more visible to others. As for maintenance, after use, if it gets dirty, simply wipe it down with a damp cloth. Since it's water - resistant, it can handle light rain, but avoid submerging it in water for long periods. Also, store it in a dry place when not in use to keep it in good condition.
