Using your Basil Urban Load double pannier bag is easy. First, decide how you want to attach it to your bike. You can use the pre - mounted straps that come with the bag. If you have the Basil DBS system or the Basil MIK adapter plate (both sold separately), you can use those too. When carrying heavier items, don't forget to add the Basil Distance Holder (sold separately) to avoid the bag getting into the spokes. When loading the bag, distribute the weight evenly to keep your bike balanced. As for maintenance, wipe it down with a damp cloth after use, especially if it gets wet. Keep it in a dry place when not in use. And remember, since it's water - resistant but not fully waterproof, try to avoid leaving it in heavy rain for too long.
