    • Great Tubes
Size: 20" x 4.0
The here have held up well in my bike shop and I have never had a defect or issue with these in the electric bikes they are installed in. The supplied tools with the tubes are better than you get with some other brands. Shipping was fast, packaged well, and packaged properly without damaged item packages. ... show more

    • Top notch, all around!!!
Size: 20" x 3.0
I bought an e-bike that was delivered with a flat tube and the replacement was going to take a week to be delivered. I got on Amazon to save the day, per usual. I ordered the box with two tubes to have a spare backup. I received exactly what I ordered and I appreciate that it came with two tire tools that make the removal/installation of the tubes a breeze! My order came within the two day delivery window that was promised. I got exactly what I ordered, the tube is high quality, it inflated without any issues, no leaks, the fit is perfect for my 3” fat tire, and because of the included tool, I was able to complete the whole process in under 5 minutes. Thanks to this seller and Amazon, I was able to get on my brand new ebike and hit the trails before the manufacturer of my bike even sent the replacement tube! ... show more

    • Good Quality
Size: 26" x 4.0
These tubes seem well made and were sold at a very good price. I seem to go through 2 or 3 tubes a year on the 3 fat tire bikes I own so always keep a couple of spares on hand.

    • Not Heavy Duty
Size: 26" x 4.0
The price was appealing, but as the saying goes, you get what you pay for. These so-called "heavy-duty" tubes are dangerously thin and certainly not suitable for heavy-duty use. Compared to the regular tubes I bought from Amazon, they are a complete letdown. Thankfully, the Amazon tubes lasted for years without any issues, even after many miles on and off-road riding my self-built fat tire bike. That I enjoy every chance I get. ... show more
