2.80/2.50-4 Scooter Inner Tube with Angled Valve Stem

2.80/2.50-4 Inner Tube for Electric Scooters and Utility Carts

This inner tube is built for 4-inch rims found on electric scooters and utility carts. Its 90-degree angled valve stem makes inflation easier in tight spaces where a straight stem may not fit. It works well as a replacement when a tire goes flat. It is one of the scooter inner tubes offered for dependable use across a range of models and sizes.

Build and Materials

The tube is made from high-elasticity butyl rubber and suits several tire sizes, including 2.80/2.50-4, 9x3.5-4, and 3.00-4. The thick-wall design helps it hold air better and lowers the chance of pinch flats during installation. It is a good match for casual riders as well as anyone using a scooter for utility work.

Valve Stem Design

The 90-degree angled valve stem is made for small hubs, so a pump can reach it easily. This matters on scooters such as the Razor E300, where room around the valve is limited. Because a pump can connect without being blocked by the motor or rim, topping up air is simpler.
