Die Schläuche sind super, sind gleich leicht gewesen aufzublasen halten ihren Druck würde sie sofort weiter empfehlen. Sind sehr gute Produkte.

Not sure if there's anything I can say above and beyond the obvious. They're standard butyl rubber tubes, a little on the heavier side (20x4) and seem to be holding air just fine after about a month of daily use. Please be sure to check the inside of your tire before replacing your tubes. I found a tiny hair sized metal splinter in mine that would have punctured these replacements had I not caught it! Oh, and I did use the tire levers, just to see how they worked. Compared to my Park and Pedros, I didn't expect them to work well, but they actually did. They didn't flex or snap off under the high bead load my tires had, so, good levers too ;)

From the weight and the overall appearance of these inner tubes, they seem like they are well made. Inner tubes have gotten quite expensive, and it was nice to see that these were still reasonably priced. They installed with no issues and they have been pumped up to 30 PSI on my son's bike. I will see if they hold air over the next couple of weeks.

Got for one of my sons EBikes. They fit well, easy to install and pump up, have lasted a bit now. Doesn't seem to be leaking. Great price for a 2 pack.

The tubes are not that strong and adorable. They make a stronger more durable inner tube actually for other things. I would suggest doing that however I did get one of the tubes out of the two to install without putting a hole in it. If you get any of your clips in it or your tools on this, it’s going to slit the tube.
