Bought a 20x4 fat tire ebike and before even riding it I installed these liners and then put some Flat out into the tubes. Front tire I disassembled and installed easily. Back tire I left attached to the bike and slid it in between the tube and tire, was a headache but doable. I'm now 300+ miles and still flat free *knock on wood* which is saying something cause my kids can't even ride down the sidewalk for a block without catching a flat. 10/10 would headache again.

The Ultraverse Protector is a great option for those with thick tires on their bikes. I bought it for my cousin, who has a mountain bike, and he loved it. It's very easy to install by following the steps in the manual or the video in the product description. It provides excellent protection against punctures and damage, making it an ideal purchase for cyclists looking for more durability and security for their tires. Highly recommended!

Does NOT work. These guards are crap. I bought these for my son, we live in Florida and he kept running over sand spurs and getting flats. Thieve did not help. Still getting punctures. Also, when you insert the strip in the tire, it does not mold to the tire. Flat material does not sit flat on a rounded surface. Do not buy.

The Ultraverse Tube Protector is an excellent investment for cyclists who don't want to worry about punctures on rough terrain. Its durability, ease of installation, and high effectiveness make it an essential tool for those who use fat tires and seek the best performance on their rides.
