I wonder whether this is the one @toutestbon has bought, which definitely wasn’t a 36er tube. He may confirm.
I ordered it on August 30, 2025 (same model, same seller on AliExpress). Instead, I received a red 29" TPU inner tube… This isn’t the first time I’ve received an item different from the one I ordered. I couldn’t be bothered to send the product back to China. Maybe they added it to their catalog before actually producing it.
I just installed a RideNow tube on my hatchet (26x4.85 tire size). It was the only fat tire TPU tube I could find that was suitable for up to 5". I also was pleased to find it available with a schreader valve.
Instillation was way harder than a butyl tube. I hope I never have to swap it on the trail. To seat the tube, I squished half of it in, then used zip ties to stop it from popping out while I squished the rest in. There was some moderate twisting, so I unseated both tire beads and went around the wheel pushing and pulling the tube from both sides to get it properly oriented, then reseated the tire.
So far so good. I took it on a very punishing trail yesterday and had no issues. However, I also didn’t notice any improvement in the handling or maneuverability of the uni. After all the effort, that result was a little disappointing. More skilled riders may have different experiences, though
