I own several electric bicycles and purchased multiple of these products. However, I own many bicycles without fenders, so I've found that they're not very useful due to mud splash from melting snow. I can only install and use it on one bike, so I no longer need them. For those looking for one! It doesn't let water through, even on rainy days. The material seems to be similar to the wetsuits worn by surfers. Apart from the scratch in photo 6, there are no damaged or dirty parts. For those looking for one! *When shipping, it will be folded in half and sent in a Mercari Compact box.
