## Description

Product description

Review: Fat tire savior - The best fat tire and dirtbike sealant we have found and love the gallon size. Pump clogs but clears with a strong push and love that it is water cleanup.
Review: Stuff works like magic - This stuff is like magic, just watch the youtube video of the guy that drill 4 holes in his tire/innertube. He filled once, it sealed them everytime, well accept for the last one but if he had put more of this in, it would have sealed that one also... i live by this stuff on all of my ebikes paired with at least 2mm thick heavy duty pivotrax innertubes .. this is a no brainer if you watch that video..

### ⭐⭐⭐⭐⭐ Easy to install peace of mind
*by M***H on November 28, 2025*

Based on all the positive reviews out there about this product, I used this in my fat tire e-bike as soon as I bought it. I don't know how many flats I would have had, but I've ridden over 1,000 miles without a single problem. Maybe I'm lucky, or maybe the product works like a champ. Either way, it's great insurance against a flat tire - one of the worst experiences in biking. Some people say it's expensive, but it's actually quite the opposite. I think the people that say that haven't had to replace their original (cheap) innertubes. I just bought good innertubes from Kenda and they were $24 each, which makes this a no-brainer. It's guaranteed to last 10 years - that would be at least 40,000 miles for me, so basically the life of my innertubes. It's not at all messy to install if you follow the instructions. A block can happen occasionally, but it's really easy to clear and continue filling. I've only used the bags and not the pump, so I can't vouch for the pump either way. But since the cleanup is water and a paper towel, installing this in your tires is nothing to be afraid of. If you have a clog, stop and clear it before putting excessive pressure behind it, because I can see where that would cause a mess. Just disconnect the hose and take care of the problem, reattach the hose and continue. I think I had to do that once during the installation of two tires. Again, I'm using the bag and not the pump. I expect it to function as designed since I've seen youtubers doing tests for functionality and it definitely works. It's great peace of mind when you're miles away from home and there's almost no chance of you getting a flat tire.
