FlatOut Off-Road Multi-Purpose Tire Sealant - Prevents and Repairs Flat Tires - Seals Leaks - Contains Kevlar - Tubeless Tire Sealant - 32-Ounce Bag - Pack of 1

Self contained bag with a built in spout to prevent messes. Putting this into bike tires before encountering a puncture can help you get home without losing air pressure, allowing you to repair the tire when convenient!My E bike allows me to travel further from home, but also made me nervous about getting back home after a puncture. Many people will carry a tool kit and spare tube on every ride. Not something I would want to do on the side of a highway.

THE PROBLEM:I have run into a situation recently where i was getting flat tires on my new and new(ish) ebikes. I tried going to the local bike shop, and surprise, they were ALL out of 20x4 innertubes... because people buying ebikes online and getting flats.They sell really legit innertubes at the local bike shops, but it seems that a lot of inexpensive ebikes you buy online will come with somewhat janky tubes and tires, and to make matters worse, many people are gonna load down an ebike with weight (including the bigger and bigger batteries and fabricated rims)... the motor and the battery can handle it, but maybe the weight causes a flat.THE SOLUTION:After a few days in this situation of being stuck in a hotel with a flat tire and a bunch of gear, i came across a bunch of youtube videos where folks were doing CRAZY stuff to their bike tires after filling them with various kinds of goop (or just air).In every case FLATOUT was far and away the best solution!!i even saw one person DRILL a 5/8 inch hole in his bike tire, and it STILL didn't go flat (and this was after he had already poked 4 other holes of various sizes and descriptions in the same tire, and the same fill-up of air)I ordered some flatout to the Amazon Fresh market, and i was back on the road the next day!CONSIDERATIONS:I purchased a set of valve-core tools for like 10 bucks, and it came 3 different size tools, extra stems, cores, caps and surprises. I would HIGHLY recommend you get a kit like this.What i found out when i went to remove the valve-core was that the core in my innertube was in there crooked or at least kind of loose. it wasn't right. I think that was actually the cause of my leaking tire, but i would have never known without putting in flatout.so if YOU have a brand new F(l)at-tire ebike, *definitely* CHECK your valve-core, but go ahead and add some flatout while you are doing it. This stuff is legit....And make sure to get a nice set of valve-core tools and accessories, just in case. Not only will it save you any problems with your valve-core, but you will feel **steampunkAF** knowing that you own a valve-core tool.(people don't say ^^"steampunkAF"^^ enough these days, do they?)^^finger quotes

Works Great

Had slow leak in rear mower tire. Top of lid was tough to get off with the tube, but finally got it. Used on my bad boy zero turn mower back tire. Checked a week later and it still seems to hold air just fine. Was able to get my mowing done.

Good work 👏

i havent caught a flat in 2 years!!!! and i live in nyc!!!! you must always check tire pressure!!!!! peashhhh!!!!

This is great

I was looking for a less-expensive sealant for bike tubeless setups and came across this. It was definitely cheaper than Stan's and other sealants, but my results have been mixed. First, the pros: good price, long lasting, and sealed larger (quarter inch) punctures. Cons: too thick (couldn't seal tiny air leaks during setup), also needed a lot in each wheel. I'm going back to a more liquid sealant.
