HEB - Heavy Duty Bike Tube for Ebike Tires - Puncture Resistant Inner Tube for 20x4 / 26x4 Bike Tire, Fat Tire Tube, MTB, 20 inch x 4.0 inch and 26 inch x 4.0 inch Bike Tubes

This is my second pair. I love it cause it 1.3cm thicker than the original. It last for along time with Flat-out sealant. Both combined no more flat tire ever.

Fit perfect ,good quality 👌

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.

Wasn't for me. Its for a friend. Right size and price.

Ordered these tubes to replace the original tubes on my grandson's TST R002. The rubber is much thicker than the originals. Some of the reviews complain about the puncture resistant but I don't know any tube that is going to resist a puncture.

Worked great

Omg I have 7000 miles on my ebike and had it 3 years with these imtires and I only wore them down half ways I'm very very pleased with them and I plan on getting another set just like them also they don't howl in the street

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… HummDeflated 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

Se ve bastante resistente

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

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

Works as it should
