If your electric scooter needs new inner tubes, this 2-pack has you covered! These are specifically designed for 10-inch electric scooters with the 85/65-6.5 size that fits most popular models. What's really great is they're thickened to 2mm - that's 0.5mm thicker than standard tubes, which means better puncture resistance and durability. They're made from high-quality butyl rubber that can handle extreme temperatures from -60°C to 180°C, plus they're resistant to mineral acids and wear. The bent mouth valve design makes inflation so much easier, and they even include a valve extension rod to reach those tricky valve positions. The package comes with everything you need: 2 inner tubes, 1 valve extension, and 2 tire levers to help with installation. These tubes also work with pocket bikes, mini choppers, and mobility scooters - pretty versatile! A quick tip: when you get them, test for leaks by soaking in water before installing. If you see bubbles, contact the seller for a replacement. Much better than discovering a leak after you've already installed everything! Perfect for when you need reliable replacements that will last longer than the original tubes.
