Easy Inflation: 2.80/2.50-4 Tube with Bent Valve
Don't let a flat tire sideline your ride. This Universal Parts Premium Inner Tube is engineered specifically for small-diameter 4-inch rims found on many popular electric scooters and utility carts. The standout feature is its 90-degree bent valve stem, which provides effortless access to the air valve in tight hub spaces where straight stems simply won't fit.
Technical Performance Features
- 90 ° Angled Valve Stem: Specifically designed for small hubs (like the Razor E300), allowing you to attach a pump nozzle without fighting against the motor or rim.
- High-Elasticity Butyl Rubber: Features a versatile expansion range that fits tire sizes 2.80/2.50-4, 9x3.5-4, and 3.00-4.
- Thick-Wall Construction: Manufactured with consistent wall thickness to improve air retention and provide better resistance to "pinch flats" during installation.
- Multi-Purpose Utility: A reliable replacement for everything from kids' electric scooters to hand trucks and garden trailers.

Mechanic's Note: When installing a tube on these small 4-inch split rims, it is very easy to "pinch" the tube between the two halves of the rim during reassembly. We recommend inflating the tube slightly (just enough to give it shape) before bolting the rim halves together to ensure the tube is tucked safely away from the edges.
