Using your Restrap Wald Basket Bag is a breeze. If you have a Wald 1372, 1392, or 157 basket, just choose the right - sized bag and use one of the two attachment styles to secure it to the basket. This way, you can stylishly carry your stuff around town on your bike. When you're off the bike, simply use the sturdy carry strap to turn it into an everyday bag. To keep your belongings safe, always zip up the double - zip compartment. As for maintenance, wipe the bag with a damp cloth regularly to keep it clean. Avoid exposing it to harsh chemicals or extreme weather conditions. Remember, the basket is sold separately, so you'll need to purchase it if you want to use the bag on your bike.
