It's a word of difference between the standard tires te bike came with and these tires here. No worries about get a flat tire with this tire

Great tube for a great price. Living in the desert where every plant has thorns, my advice is buy them.

Very nice heavy duty tires. Much better quality than came with the bike!

Goatheads! Darn thorns (seeds) are hard on my ebike tires. These tubes shipped fast and installed easy. I am getting good at tire repair, darn goatheads. I have installed a liner and these HD tubes in a valiant attempt to defeat the nasty goathead. So far...great.

After replacing my Ebike 20" Fat Tire with an inferior tube, I decided to purchase this puncture resistant tube. Honestly, you can tell its thicker more heavy duty and far more durable that the other tube it replaced. Ive had no issues with this tire since installation. Its on a tire that has almost no tread and has almost all the nubs worn off. I regularly ride on questionable terrain, broken tree branches and sidewalks littered with debris and materials. This tire has still not failed. It is much higher quality and should have purchased it originally when the oem tire failed. Will probably need one in the future as well. Recommended. Its a better tire.

My experience has been these tubes are of good quality. I use them on my cargo E-bike that gets a lot of miles on it, in fact I have over 1,000 miles on one tube I put in the rear and no issues. They also don't lose any air, the pressure seems to hold at 20 psi. As a result of their performance, I have purchased 2 more.

Just received the package. Put first tube in, pumped it up to 13 psi. Looked ok. Walked away and heard a high pitched squeal coming from the tire before I put it on. Thought I had a new tube in it. Didn’t hold any air. Pulled tube. Here there’s a leak in the seam across from the valve. If I knew I had to patch the tubes I would have fixed the one I had… Never again from this company!! Well. Imagine that. I finally got around to try the other tube, since I figured they ship 2 hoping 1 is good. Well think again. Pumped 2nd tube up to 10 psi, let it sit, Lost maybe 1-2 psi overnight… Humm Deflated to insert in tire went great. Pumped it to 15 psi of 20 max. Looking good. Nope. Next morning flat again… What 2 pieces of ……!!!!

Great buy

These are definitely the best 20"×4.0" fat tire ebike tubes that I have ever ordered on Amazon. The price is very reasonable and the quality is excellent

Se ve bastante resistente

Tubes go in tires I have tires. Put tube in. Drive away on tires. Pretty straight forward.

Works as it should
