QuickStrike Tire Sealant - Small Tire/Bicycle Formula - New Formula - Prevents Flat Tires - Seals Leaks - Contains Kevlar - Tubeless Tire Sealant - 1 Gallon + Tool

Seems to work very well, I’ve put it in all three of my bikes and I have not had a flat in any of them in the past four months. It seems to work better than the different brands of inserts I have been using over the years, were I would have experienced at least 1-2 flats per bike by now.

I bought this huge jug even though I only have 2 bikes, because it is big enough to do six bikes for only twice the price of the jug that only does one. It was easy enough to install in our bikes. If you are wondering, one pump is 1 ounce, so my bikes needed 10 pumps per tire. Many folks complain that it clogs the air fill nozzle, that remains to be seen. I have not gotten any punctures that I know of, but after doing my research I think it will do the job.

The best product on the market. Works great. Love to go on long bike rides without the worry. I also use on my ride on mower, we have goat heads and it keeps me from getting flat tires.

Easy to apply messy

I purchased this after reading pages of product reviews and testimonials.About 1 week after receiving FlatOut, my E-Bike got a rear flat tire. I removed the valve stem, added Flat Out to the tire, replaced the valve stem, rotated tire and added air to proper pressure, continued rotating tire. Within 10 minutes of adding product to tube/tire, it was fixed! I was so impressed, I ordered a gallon, as I have 6 E-Bikes and I am going to treat all 12 tires (before they run over a nail) as well as my lawnmower and wheelbarrow tires!! This really works. No more Fix-A-Flat. That stuff is garbage compared to FlatOut.

just follow the direction , it really work

Not for tubeless or anything for that matter. I got this to replace the way too expensive tubeless sealant. I live in Phoenix right now flats are just a matter of time. I do not trust this stuff to get me around trip.Will not get, one of my bike's, tires on bead. It's not an easy rim to get on but one side is set and I'm using an air compressor. This method has never failed.For the tires that did inflate... They deflated in about 30 min. Would not seal a small leak in the bead on one and would not seal some tiny holes in the other. I let it sit for a couple hours while refilling them with air and spinning the liquid around, and they still would not seal. I thought at one point it finally took but as soon as I filled them with riding pressure, liquid blow out from the holes.Don't waste your time and money. Only thing that last a lifetime with this is the disappointment.

No need for tire liners.. Just get these ultra sturdy tires and a bottle of Flat Out and say goodbye to 99 percent of flats.They are cheaper than some liners.And they look 👍
