I am selling this item because I purchased it, but it doesn't fit my bicycle. I opened the package once, but it is unused. The following is an excerpt from the manufacturer's website: [Material] 100% Polyester [Body Size] Approximately width 42 x length 35 x height 24-42 cm [Product Description] Compatible with electric assist bikes and large baskets. Designed to fit various basket shapes, such as square, round (D) type, and wide baskets. Elastic rubber is used on the back of the cover, so it fits baskets of various sizes. Of course, it has a 2-stage storage design, so it's neat when you don't have much to carry! Plenty of storage when you have a lot!
