High-Quality 8-1/2 x 2 Inner Tube: Perfect Fit for Kid Gas/Electric Scooters & Pram Strollers Review

Photo speaks for itself. I had to replace the left one and the tube says 8.5 x 2. The one I ordered is on the right and is said to be the same size (note there is no size tag on the side). Extremely fast delivery but extremely wrong product as it is too small.

I ordered this for a Zero 9 scooter that uses a tube as pictured. The zero valve 9 goes through the rim and then turns 90 degrees at right angles to allow the pump to be placed on top. This bend is 90 degrees but protrudes approximately 45 degrees diagonally to the direction of the hose. So when you inflate it, the valve will eventually twist and break the tube.

I bought this hose on purpose because it was the only hose that had a 90° angled valve stem (as shown on all the product images). When I opened it, the stem was barely bent and too long. This is a problem because I need to install it on the front wheel of my Xiaomi M365 scooter. Due to the wrong stem, it doesn't fit in the wheel of the scooter. When I inflated the tube, it was also completely crooked!
