Good for ebike tires
Size: 1 Gallon + Tool, Set name: Small Tire/Bicycle Formula
Got it for my son’s older ebike that my wife rides now. He kept on popping tubes, maybe because of his weight. Anyhow, I fixed it up for my wife and put some FlatOut in it to prevent flats. Seems to work so far. Got the off road FlatOut for my ebike’s fat tires. Easy to add to the tires. The pump clogs up but it’s easy to clean. I will always add this to all tires moving forward!

This product work so well it will surpass your expectations it did mine
Size: 1-Pack (32 oz)
This product is well worth the price. I had a small branch puncture a hole through the sidewall of a tire on my 4 wheeler. The hole was at least 3/8” and was done by a tree limb so the edges were jagged. I followed instructions on the product yet the whole time I thought I was wasting my time and the product most likely. I was pleasantly surprised and wrong. It sealed as soon as re inflated the tire and hasn’t leaked down in over 6 months now. I was so impressed I put 2 packs in everything I drive on road and off road.

Best fix for flats that I've ever used
I have a large zero turn mower that is 10 years old and had a slow leak in the front tire. I tried fix a flat but even a full can would barely get any of the product into the tire and would end up oozing around the valve. After a long search, I found FlatOut. I was reluctant at first because it required removing the valve core, which I had never done. (I'm a 60+ year old female.) But the ratings were so high and the fact it was made with Kevlar, changed my mind. And I am so glad!! The instructions were so simple, core valve came right out (and the tool and new core valve is included), the tube that you pull from the bottle, fit snuggly on the valve stem yet was not difficult to put on. I elevated the bottle, added the amount I thought it needed, removed the tube, pushed it back in the bottle, replaced the cap, and then put the new valve stem back in. It only took a few minutes. And no mess! I had put on rubber gloves, expecting some to spill but it's a thick liquid and does not seep out anywhere it's not supposed to! I filled the tire with air and checked it each day for a week to make sure there was no leak before I used it. I then mowed some rough ground that is hilly and rocky and when I was done, the tire was perfect. I was so pleased I did the same thing to the other tire that never lost any air because I didn't want to wait for a leak.
BUY THIS PRODUCT if you are tired of messing with slow leaks or flat tires! I will never use anything else. I purchased a package of core valves and taped them on the bottle so I'll have them when needed! I would give this product 10 stars if I could. It states on the bottle this product was used in the military, so it really has been tested. Thank you FlatOut for a product that actually does what it says!

IT JUST WORKS!
Size: 1-Pack (32 oz), Size: 1-Pack (32 oz)
I recently found a piece of wire stuck in the side wall of my Zero Turn mower's rear tire. The tire has less than a full season of use, so I was looking for an alternative to "FIX" my sidewall puncture instead of removing it and patching or replacing. After looking up several different products, I decided to try Multi Seal. After reading the directions, I removed the valve tool that was included with the bottle. It was a little confusing, but the tool is basically a "stopper" for the clear hose that's in the bottle. Once I removed the valve from the stem, I connected the clear hose to the stem and proceeded to squeeze the product into the tire. I was surprised as to how easily it flowed into the tire. It was much easier than other tire sealants I've used. Although, its recommended to use half of the bottle in a rear tire, I used significantly more. I wanted to make sure the sealant would get to the sidewall. When I was finished adding the product, I replaced the valve in the stem and inflated the tire to the recommended pressure. It was at this time I pulled the wire from the tire. I started the mower and drove it for a few minutes. When i stopped, the product had started to escape the tire through the puncture. In fact, I had another unknown puncture that showed signs of the Multi Seal product. After a few minutes, air was still escaping from the punctures so I ended up driving the mower for about 10-15 minutes. This seemed to do the trick. Over a week later and 1.5 hours of operation later, the tire is still holding air pressure. This product is the BEST tire sealant I have ever used. I will be adding it to all my non-highway tires that I own.
