Inner Tube for Electric Scooter 12x2.125/2.5 45°

Inner Tube 12x2.125 / 2.50 — Reliable Riding Without Puncture Worries

Looking for a replacement inner tube for your Xiaomi, MS Energy, or other electric scooter with a seat, e-scooter, or e-bike that uses wider 12-inch tires? This inner tube with 12x2.125 / 12x2.50 dimensions and metal valve at 45° angle is made of high-density thickened butyl rubber, providing superior resistance to wear, punctures, and pressure loss under load.

It features an auto valve (Schrader) bent at a 45° angle. This specific angle is ideal for rims with deeper grooves and lateral outlet, as it prevents the valve from catching the brake disc, rim, or frame during rotation, while also allowing easy access for the pump or compressor hose. The tube is compatible with numerous models, including Xiaomi, MS Energy C10 and C11, Segway Ninebot, and Kugoo B1, B2, and V1 models.
