Armour Tire Insert, No Flat Bike Tire Liner, Puncture Proof Bicycle Tube Protector, Stops Flats from Thorns and Goatheads Compatible with E-Bikes, Mountain Bikes, and More

I installed the Tannus Armour tire insert on my electric bike and it's been a huge improvement. Installation was easy and took about 30 minutes per wheel.The ride is smoother and more responsive, and I've had no punctures since installation. The insert absorbs bumps and vibrations, making for a more comfortable ride.I highly recommend the Tannus Armour tire insert to anyone looking to enhance their bike riding experience.

I have had this tire armor for 30 days without a flat. That's never happened before. Before I started using this brand of armor, I couldn't get through more than about two days max, and sometimes multiple flats per day. They're expensive, and a real pain to install, but once installed they have protected my tubes, and I ride a lot. The goatheads are so bad where I live, and have proven brutal on bike tires, yet these really did the trick. Gotta say thanks!

Doesn’t take up space. Good for quick flat fix. Easy to use. Good quality, I recommend.

Just to be clear, this is for a single insert.Pricey for only foam. I will review again if it saves me or not.Tough to install but does go in.

Upon reading many positive reviews I decided to make the investment to purchase these for my fat tire ebike. The instructions they supplied were worthless, but I did find some good YouTube tutorials that helped to ease the installation.Oddly enough one of the videos I stumbled across was a scathing review of how poorly these things hold up and perform as advertised.And just a couple weeks in I had my first flat. And my second, and my third and so on.What irritates me most is how they deceitfully advertise these as being able to withstand some many punctures and how beefy they show that “brand new” cross sectional area, which disappears in just a few months. The install date of these were in May, and here it is September and they have compressed to about 1/5 of what they started at. Which also makes the tube downsizing a joke.As of writing this review today I am taking these out and going with a traditional tire liner.

Ok so its 10/28/23 here in the Chicagoland area. I recently purchased ( 2 ) of these for my fat bike . Buyer beware , your current tubes will not work . I went with the recommended 26x3.0 tubes & they worked splendidly. Now onto the install . I researched the fat bike install on YouTube, I watched 4 different installs . The Tannus armor official website says to trim them PRIOR to install and use baby powder , I personally did NOT do either. I figured I'd attempt to install them without a trim because I'm paying for 100% protection. I want 100% protection, worst-case scenario, I'd pop them out and trim them down if need be . Thankfully I didn't. Lets fast-forward the basics and go to install , I pumped about 3 or 4 pounds into the tube before I installed tubes into armor , line up the stem properly and install the first part into the rim. I was certain to push the armor back the the back of the rim , it makes for a smoother install for remaining tube/armor . Constantly watching to see that the tube or armor are not kinked or twisted or you'll have waddle ( unbalanced armor/tube ) . Once you have the tire on both sides of rim , set the tire down on the ground and roll it 10 or 15 feet ( prior to pumping remaining air pressure ) . Once you feel comfortable with this. Pump a few pounds and STOP ! Check ✔ both sides of the rim thoroughly on the bead to make certain there's no bulging. Then proceed to fill tire to recommended capacity. ( My fat tires say 20 lbs. Max ) I'm a big guy ( 6' 240 lbs. ) so I'm going with 20lbs. A short test run is recommended before any serious riding . Check both tires again thoroughly after. I read multiple reviews on these installs here on Amazon, one bloke said he was a retired engineer and he spent hours attempting to install these , finally took his bike to a bike shop. I was a bit perplexed by this. So I did MY own research. Its not rocket science, doesn't take any special skills or fancy tools aside from the usual tools needed to change a tire. Takes a bit of patience and a little elbow grease. I hope this review helps you. And PLEASE don't trim down & throw away good money if you don't have to. Good luck and be safe out there 🙏... P.S. the total time for both tires took me less than an hour. That's popping them off the bike , breakdown & reinstall. * UPDATE * It's now 12/23/23 . I have successfully ridden over 1500 miles on the Tannus Armor & ZERO flats ! I'm a daily commuter who rides in rain & snow . I have hit some pretty gnarly holes and bumps on the trails and the pavement and I've not had a single issue .

My ebike has 20x4 tire and I've had three Flats on the rear. A bit of research later an I picked up some Tannus Armour and some Slimed. I installed it on my rear tire in under an hour, not too hard if you follow the instructions, and so far so good after 3 weeks.

I purchased one insert as a trial since reviews were mixed as to how easy it would be to fit and what the ride would be like. In the event the fit was easy with my Schwalbe Smart Sam, Active, 2.60 tyres. Riding on the road I noticed no difference; over roots,, etc. it feels more comfortable. I've consequently ordered a second.

I used a smaller tube fit good rides super smooth and half the pressure

For £134 i expected to get x2 of the 26x4" armor, unfortunatly i was wrong and only 1 turned up, have spoken to tannus uk and the price for the 26" armor is £50 per item, trying to return the item isnt the best either, they require you to pay for return shipping which for the price is mad.avoid at all costs!!!!!!!!
