Usage Tips:High-quality performance: 10 inch e scooter hose is made of high-quality rubber, which is thick and durable, heat and wear-resistant. Our thicker rubber material makes it less likely that the tyre will be punctured and air will escape. After installation, the comfort is significantly improved and has a good shock-absorbing and cushioning effect, which makes driving more stable and safer. The cushioning is better and easier to install than solid rubber tyres 90 degree silver valve: 90° silver nozzle valve design, more convenient to inflate. No rust, better quality than copper. This curved valve is easier to inflate than a straight valve. Excellent quality: the inner tube is made of butyl rubber with good resistance to penetration, mineral acids and ageing as well as good resistance to extreme temperatures (-60°C to 180°C). With 90° camber valve. Replacement for the front/rear wheels of electric scooters. They have a double thickness of 1.8 mm for longer durability. The valves are better rust-proof and can withstand higher pressure. Wide compatibility: replacement hose 10 inch is fully compatible with the front and rear wheels of most 10 inch electric scooters, for hoverboard 10 inch inner tube compatible with Soflow So6/So4 Pro, Ninebot MAX G30 G30P G30LP, Kugoo M4 M4Pro F40 electric scooter Assembly and customer service: 2 x e-scooter hoses 10 x 2.5, please check before installation whether the hose is fully sealed by placing it in water.
