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

The review is for the install of the product. Actual benefit can only be determined if we get a goathead bur so common in Montana. Place the stem per the instruction, the upper part of the rotation. The product flowed easily with very minimal overflow. Release the stem core slowly to minimize the possibility of bead loss. I put the bikes on a hanging type bike carrier to keep the wheels off the ground. In my opinion this greatly increases efficiency of the application.

It went in easy, I have had a puncture to see if it works. Maybe that's the secret if you have it in you won't get a puncture.

Recently bough a new e-bike and my biggest worry is getting a flat while away from home. I can fix a flat if need be but if I can avoid having to do that for under $30well why not. Installing in the tires was easy enough and took me about 15-20 minutes. There are competitors but one thing that sets this apart from them is that it is designed to stay fluid and work for 10 years (which is likely longer than the life of my tires. The reviews and tests I have read/watched indicate that it works well and hopefully I'll never have to find out but I ride with a lot more confidence knowing Flatout QuickStrike Tire sealant is in my tires/

I would advise anybody who uses this product to remove the valve with a proper valve removal tool instead of using the plastic cover on the bottle. The plastic is too soft to remove stubborn valves. It breaks and leaves pieces inside the valve which are impossible to remove.

It went into my 26”x 4” E-Bike tire easily enough. Easy to clean the pump afterwards. Some complain of clogging but I had no issues here. Has a quite a few people who swear by Flat Out. Lasts 3 times longer than another popular brand according to some reviews and the maker of this product.

I spend winters in a desert area and ride on roads known for goathead thorns and broken glass. So I installed Flat Out in my fat tire e-bike few years ago and have had no flats. I bought another e-bike and took it out for a quick test ride and had a flat within a couple miles. I replaced the flimsy tubes that came it’s the bike with heavy duty tubes and added Flat Out and no flats. It’s easy to install in you tubes and even comes with a tool to remove the valve stems.

The tires on my ebike were pathetically leaky after miles of fun riding off-road trails. Flat-out really sealed the deal! After a simple installation process, I can (and do) now confidently ride everywhere, and my tire-pump wonders why it's been in its storage bag ever since! If you are wondering which flat-out formula is really best for ebikes, this is it. I originally purchased a lower-priced version of flat-out advertised for ebikes that ended up being too thick for my tires. It took a bit of effort to clean that out to make way for the bike-specific formula, but it was possible. Thanks for a fantastic product!

I bought the 16oz bottle three times as needed for three different bikes as needed. Great product, but they got greedy and stopped selling the 16oz bottle. I don't need 32oz. Update: I went ahead and bought it it because it's the best on the market. I need to do one bike, and now I have to store enough to do another bike if that ever comes up— which isn't in the plan.
