Flat Out Off Road Tire Sealant, Sportsman Formula, Prevents Flat Tires, Fix a Flat Tire, Seals Leaks, Contains Kevlar, 32 Ounce Bag, 4-Pack

I've got a big, fat tire electric bike that weighs about 80 pounds unloaded.I Started getting flat tires. Having to walk my bike home 5 miles with a flat is not fun.Fixing a big fat tire flat is a slow and time consuming process.Regular bike levers usually won't do the job. I have to use motorcycle tire spoon levers to fix a flat.Its not something I'd want to do on a hot summer day, or in the middle of a downpour, or with sleet and snow hitting me in the face, my hands freezing barely able to hold the tire levers. Changing a flat on a electric bike, the power cable connector has to be disconnected, zip ties holding the power cable have to be cut, or electrical tape holding the cable in place has to be cut.Doing all this in a rain storm could be a very electrifying experience in a bad way.I started looking for a better way, a better solution to prevent flat tires.After watching several YouTube videos about different solutions.I tried the Tannus Armour foam liner, right away I got a flat with that and I still had to walk five miles home with a flat tire. It made rolling my bike on a flat even more difficult.Once home, I had to cut the tire liner with a pair of scissors, just so I could remove the tire liner and pull out the bad inner tube. The tire liners are expensive, and didn’t work for me.I went back to YouTube, watched more videos on how to prevent flat tires.I stumbled upon some YouTube videos about flatout tire sealant.One of the Youtube videos shows a guy using flatout and then putting nails and drilling holes into his bike tire, and the FlatOut sealed the nail punctures and the drill holes.I was so impressed, I bought a couple gallons of flatout. There are different grades of flatout specific to the kind of tire. They have a grade for motorcycle tires that I use on my fat tire bike and a grade for regular sized bikes that I bought for my other bikes.The flatout really works. I'd go through nails, screws, big staples, and glass, get all kinds of punctures, and the flatout sealant would squirt out the holes and I'd just keep my bike going at a nice and steady speed, and the tire would seal.It's important to keep the bike rolling when you're experiencing a flat. It helps the tires seal properly. If you were just to pull over and stop your bike the sealant wont seal as well. So keep on rolling when you get that flat.Sometimes the sealant will get on the fender or the side of the bike. The sealant is non-toxic and is easy to wipe off.I had nine or ten punctures in the tire before I finally decided to put in a fresh inner tube and more flatout.Since using FlatOut, I haven't had to walk my bike home.I wish I had known about this product years ago.

This stuff really works! I got a flat from a nail on my 20x4 fat tire ebike that had FlatOut in it already. I pulled the nail, spun the tire and started pumping it up. It was holding air until I spun the tire again but forgot to disconnect my pump and broke the pump. I rode an hour on what little air I was able to fill with before having to walk to the closest fire station where they filled my tire. I was able to ride home a couple more miles after the fill.When I got home, the next day, the tire was flat again. I spun the tire again slowly to get the FlatOut moving in the tube, and added some air. I kept repeating this every 4-5 psi until I got the tire up to 20-22 psi. Tire held that air pressure for the next few days and I've since put over 40 miles on the bike and tire without issue and still holding air.I used 1/4 of the bag I got for each tire...1/2 bag for both tires.

So I have this in all 4 tires of mine and my wife’s E-bike tires. Last week it paid for itself easily. We were 8 miles from home when I ran over a 2.5” nail. I literally pulled the nail out, heard a hiss of air for about 2 seconds and it sealed itself up instantly. It’s been a week now and my tires solid. This stuff is fantastic and very easy to install. Everything you need comes with it. Follow the instructions and you’ll be on your way in minutes. I highly recommend this, especially if you're like us and ride 15-20 miles from home. This stuff saved me!!!

It worked but the valve remover tool didn't work, the plastic was too soft and would not remove it.Other than that it worked to stop the leaks so far.One tire was down about a lb or two so still checking them after 4-5 days.I used this product on my lawn tractor tires.Two front tires and one back tire so had to use two of the Flat Out bags.Still cheaper than buying three new tires.

I bought this for our E bikes equipped with 26 x 4 inch tube fat tires. They currently have not experienced a flat so this was for flat prevention. For trial purposes, I have only done the rear tires on both bikes about 16 pumps each or 16 ounces supposedly. We have not noticed any difference in riding or handling of the bikes with just the rear tires having flat out installed inside. So now we will see how the front tires with no flat out compare to the rear tires with the product inside. Meanwhile I can tell you that I have a hose cart with 4 inch tube equipped tires that had 1 tire leaking at a rate of about 1 pound every 30 seconds. At least that was what the Dewalt compressor indicated. So in about 15 minutes it was flat. I thought this slower leak cannot be a seam failure or something catastrophic with the tube so I would try flat out on it. I followed instructions and installed about 5 ounces of Flat Out in it inflating it to 15 pounds. I then spun the little wheel quickly to distribute the product. Then several minutes later I added a little bit more air to top it up again bringing it to 15 pounds pressure. It has been several weeks now and it still is holding air so the product works obviously. We will see how the bikes make out in that department but I would be optimistic that it will work. The nice thing about the product is how well everything including the pump clean up with water when you are done. I would say it is a cool product to have around.

I ride an ebike to and from work and I get flat tyres all the time... probably 60 or more in the past 3 years. Spent over $1000 on new puncture resistant tyres and tubes and inserts...nothing worked to prevent Flats...then I bought flat out and I tried it after running over a nail on the way home from work. It's been about 3 weeks and my tyre is still solid and holding pressure...I'm very happy I bought this stuff! Very easy to use just remove the core from the valve stem and squeeze some flat out in the put the core back in and air up and spin the tyre...you may have to put more air in after the spin because the flat out takes a moment to do it's thing....but after that you're good to go! Sealed up tight and no mess
