Since adding Flat Out to my tires, goatheads are no longer an issue. I even had a 1"x2" piece of metal pierce one tire, and while it eventually went flat, I was able to make it all the way back home (over two miles) before it did. Another time, I picked up a 1/4" wide by 2" long nail, pulled it out, and kept riding back home, and that tire still hasn't gone flat. No patches, no hassle—this stuff just works! It can't stop all flats, but it will greatly reduce the number of them you have to worry about. I highly recommend Flat Out! Review: It truly works!! - I would not ride my ebike without this product inside of my Allscapes!! Hands down this is the best sealant that is available. I changed my rear break rotor today and so i had a great chance to examine the tire. I pulled a staple out and found multiple punctures.. i'm telling you man, this stuff works!! i carry around a small air compressor/pump to deal with issues in real time. spin the wheel and pump it up.

Flat out! ### ⭐⭐⭐⭐ Application frustrations and suggestions. *by D***F on May 25, 2025* I just finished putting FlatOut QuickStrike Off-Road formula into both 26x4 tires on my Aventure.2 eBike. I put about half of the 32 oz bag into each tire. I say "about half" because there is really no way to accurately determine how much has been applied. As many other users have reported, it was a challenging process because of the frequent clogs that needed to be cleared. It took me ~ 45 minutes to do the first tire but I was able to do the second tire in less than 15 minutes because of lessons learned. Hopefully what I learned in this process can be of help to others: First, find a way to get the tire off the ground a few inches so there is no risk of breaking the bead. I used a tie-down strap attached to an A-frame ladder to lift one end of the bike at a time so that the tire off the ground. Put some cardboard or other suitable material beneath the tire to catch the inevitable drips/spillage. Rotate the wheel so that the valve core is close to the 3 or 9 o'clock position. Put a paper towel right below the valve core and another over the brake rotor, at least on your first tire. Cut the cotton tip off of several Q-tips that can then be used to push into the valve core when (not if) a clog occurs. Then try pushing the Q-tip into the valve core to feel for any restrictions that might be problematic while inserting the FlatOut. I recommend that you wear vinyl or rubber gloves. When you do start putting in the FlatOut, apply a firm, steady pressure to the bag. At first, I was only able to apply a small amount (maybe 2 seconds worth) before the flow stopped. I then had to remove the tube from the valve core, push the trimmed end of the Q-tip into the valve core several times until I cleared the clog then repeat....... I am guessing I had to do this at least 15 times with the first tire and it took nearly 45 minutes to complete. By the time I did the second tire, I had become proficient enough that I only had to clear about 5 clogs and it took me less than 15 minutes to complete. This may be a bad news/good news scenario. The bad news is that it is a pain in the a** to get this stuff into the inner tube. The good news (at least in my view) is if it clogs this quickly and easily, it should stop an air leak fairly quickly and effectively. I guess I would rather spend a frustrating hour or less in the comfort of my garage putting this into my tires than who knows how long and how far it might be to push a heavy bike with a flat tire. Especially if you ride some of the remote bike trails that I ride. Suggestions for the manufacturer of this product: Supply this in quantities suitable for a single tire application so no guessing on the amount is required. Package this product in caulking tubes so that one can benefit from the mechanical advantage of a caulking gun or design some other method of application so that an individual's strength isn't the determining factor for a successful outcome. ## Frequently Bought Together - Flat Out QuickStrike Tire Sealant Off-Road Formula - Prevent Flat Tires, Seal Leaks, Contains Kevlar, 32-Ounce Bag - Ultraverse 20x4.0, 26x4.0, 20x3.0, 26x3.0 Inner Tube Set with Schrader Valve-Ideal for Mountain Bikes & E-Bikes with 20/26-Inch Fat Tires-Durable & Reliable Performance 2 Pack with Tire Levers - Ultraverse Fat Tire Liners Tube Protection Against Flats, 20, 24 and 26 inch x 4.0 tire Size, Durable Extruded Plastic Shield for Puncture Free Bike Rides – 2 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/622073072-flat-out-quickstrike-tire-sealant-off-road-formula-prevent-flat](https://www.desertcart.tw/products/622073072-flat-out-quickstrike-tire-sealant-off-road-formula-prevent-flat) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-06-04*
