Electric Scooter Spare Part - Inner Tube 12*2.125 / 2.5 45° valve

Spare inner tube 12x2.125 / 2.50 — safe and durable riding

This is an inner tube for 12-inch wheels on electric scooters, e-scooters with a seat and e-bikes. The tube is marked 12x2.125, but its wider profile also covers outer tires up to 12x2.50, which is useful for heavier scooters and e-scooters with a seat where wider outer tires are fitted than on city models.

The valve at a 45-degree angle is the right choice for rims where the valve hole comes out sideways or is set deeper. The angled valve does not catch the brake disc, rim or frame while the wheel is spinning, and the pump head reaches the valve without removing the wheel. Before ordering, compare the valve angle with the one on the tube you are replacing — changing the angle is the most common mistake when buying an inner tube.

The butyl tube with a thickened wall lets air through less, so the wheel keeps pressure longer and does not need topping up every few days. A thicker wall also means a lower chance of a puncture when hitting a sharper bump, while the ribbed reinforcement on the tube body reduces wear at the point of greatest load.

Key features

• Angled 45° valve: car valve (Schrader/AV) in a brass design with a black plastic protective cap, does not catch the brake disc or rim during wheel rotation.
• Butyl tube: black material with a thickened wall that lets air through less, so the wheel keeps pressure longer.
• Ribbed reinforcement: a reinforced zone along part of the circumference reduces wear at the point of greatest load and increases lifespan.
• Wide size range: the 12x2.125 marking also covers outer tires up to 12x2.50, for e-scooters with a seat and heavier scooters.
• Precise measurements: outer diameter 284 mm, inner 210 mm and width 36 mm in the deflated state allow you to accurately compare the dimensions with your existing tube.
• Easy replacement: intended for replacing a punctured or worn-out tube and as a spare part in a tool kit.
