Slime 20274 Bike Tube Flat Protectors and Liners, Lightweight, fits 12-26 x 1.5″-2.125″, Flat Proof for 2 Tires

If you are looking for a liner for your bike tires, i would consider these. They fit right inside the tire and helps prevent flat tires. They function perfectly! They are also a great price. I would use these everytime. Slime is the best.

I bought an electric bike, and put on a comfort seat, a rack, and these tire protector inserts. I have had many inexpensive bikes, and inserts do help the tires last longer and have increased function and durability. I finally upgraded to an electric bike, and I was wondering if tire inserts by Slime worked on them. They fit great and work great, and installed very easily. Flat tires can destroy a bike's use so having protection is a great idea.

Perfect. Well made. Quality item.

I thought it would sort of stick or stay in place but it was fine.

you can use these on what ever kind of bike, but i espcialy recomend using these sort of things if you have an ebike.incase you dont know, this is a very tough, yet very pliable liner that goes inside the wheel, in between the tire and the tube, so is something punctures the tire it likely wont go through the tube, saving you from a flat and you wont even know that your tire was just punctured, you just keep on riding.before you install it, try to puncture it with anything, a nail, tack, saftey pin etc etc, and you will see just how awesome these things are.once you install these you shouldnt get any more puncture flatsi some what think they could include some thin double sidded tape to hold it into position, because it can be a challenge to install.the trick imo is to already have the tube in the tire and let most of the air out, break the bead on one side, and then use youe fingers to shove it between the tire and the tube

Tired of changing the kids bike tire tubes due to grass burrs or goat heads? These tube liners are the key to preventing that. Super easy to install, had to trim off a little to make it fit in a 16" wheel

Can use in any tire with an tube in it

I bought these to help prevent punctures from thorns from tumble weeds. Withing a week she got another flat. This insert isn't wide enough to protect the innertube in a 2.125 tire that most Mountain Bikes use. Waste of money.
