Hiboy DK1 Inner Tube 12.5x2.75 - 45° Angled Valve

Spare Inner Tube for the Hiboy DK1 Electric Dirt Bike

Built for the Hiboy DK1 electric dirt bike, this inner tube works well as a swap-in for a punctured or aging tube. Its 45° angled valve stem makes it easier to reach the valve in cramped wheel setups. Part of our electric scooter parts range, the tube stretches to suit tire sizes from 12" up to 12.5".

Compatibility and Usage

This tube is made for tube-type tires in the following sizes: 12x2.125, 12x2.25, 12x2.5, 12.5x2.0, 12.5x2.25, 12.5x2.5, and 12.5x2.75. It is designed with the Hiboy DK1 electric dirt bike in mind, though it may also suit other tire setups that match these sizes. Most riders swap out a tube after a puncture or once the current one starts to show wear.

Installation and Maintenance

Swapping a tube is a simple job that most people can handle at home using basic hand tools. The 45° angled valve stem makes inflating easier and helps reduce the chance of damaging the valve while you install it. A correct fit matters for both ride quality and safety, so take a moment to confirm it before you head out.
