The 5 "Golden" Inner Tube Sizes for E-Scooters - Scooter Operations Inner Tube Size Classification
These are the 5 "Golden" Inner Tube Sizes. I will soon have these five size tubes in inventory in stacks in my shop because these 5 sizes are the ones that fit most of the e-scooters that come through my shop (in Phoenix, Arizona.) The key point here is that these tubes can be dependent upon the angle of the "Valve Stem," on your model e-scooter --And Yes, the Angle of the Valve Stem can be specific as well... it is therefore always most useful to identify which tube to buy by replacing the inner tube exactly for what it is when you remove the old one. Because of the angle of the valve stem, various links are provided because they are sourced from various places. E-Scooter Tires, also have a "3 Value Name," --3 numbers stamped on them, which is similar to Motorcycle Tires. To me, the "3 Values" don't make intuitive sense, but I found this post that explains it if anyone wants to read on it. But for now, these are the Five Golden Sizes of E-Scooter Inner Tubes: [ "S" - 8.5" x 2" w/ Straight Valve Stem, 8.5" x 2" w/ Angled Valve Stem - 50/75-6.1 Fits: JETSON "M" - 10" x 2.125" w/ Straight Valve Stem, 10" x 2.125" w/ Angled Valve Stem -60/70-6.5, also called 10' x 2.50" or 10 x 2.125-2.50 Fits AOVO PRO ESMAX "L" - 10 x 2.75" - 3" w/ Straight Valve Stem, 10 x 2.75"-3" w Angled Valve Stem - 70/65-6.5 OR 85/65-6.5 (CUNFUN)
