Using this bike cover is a breeze. Just unfold it and place it over your 3 or 4 bikes on the back of your vehicle. Make sure it's well - adjusted to fully cover the bikes. When packing it away, neatly fold it and put it in the storage bag. As for maintenance, clean it with a mild soap and water when it gets dirty. Avoid using harsh chemicals as they may damage the 300D polyester material. Store it in a dry place to prevent mold and mildew. And always check for any signs of wear and tear before each use.
