Every time it rained and I had to bike, my ass was getting peppered with water and dirt from the ground. Now thanks to this ass-guard, my ass stays dry. It's the simplest, most effective way to protect your ass.
Easy to install on my Rambo e-mountain bike. I use this since I commute every day on my bike. When the snow is really slushy, or it's been rainy, this thing helps keep my pants and coat dry.
Awesome device. Tired of getting to class and sitting on wet pants during rainy days, I bought this. Installation was a breeze, and the fender is nice and wide.
I have no doubts that this will help keep my back dry, but I'll follow up to confirm next time there is rain.
REVIEW UPDATE: After many rainy rides, this is an excellent purchase! Keeps the mud and water off my back (evidenced by the amount of stuff on the underside of the fender).
