These 24 inch Bike Tubes by Positz are a simple, reliable way to keep your kids’ bike rolling without hassle. Built from quality butyl rubber, these 24″ bike tubes help reduce the chances of being stranded mid-ride and make quick repairs easy. Having a spare tube ready means less downtime and more riding.

These tubes are ideal for school bikes, weekend rides, and everyday use where punctures are just part of the deal. Keeping a box of two on hand means you’re covered when one goes flat, without scrambling for a replacement. It’s a straightforward, good-value option that makes life easier for both riders and parents.

Who are these 24″ bike tubes for?

Ideal for riders who use 24″ bikes with tyres between 1.75 and 2.125 inches, especially kids, commuters, and families who want a reliable spare ready to go. Also suits parents who prefer to keep a backup tube in the garage or toolkit so a flat tyre doesn’t derail the day.

Who is this not for?

Not suitable for bikes running different wheel sizes or tyre widths outside 24 x 1.75-2.125. If you’re using Presta valves or tubeless setups, this isn’t the right option. Also not aimed at high-performance road or racing setups where weight savings are the priority.

Why we love it

We’ve found these Positz tubes strike a great balance between price and reliability. They come out of the same large-scale manufacturing as many big brands, so you’re not sacrificing quality. Our favourite part is the value of getting two tubes in the box, which just makes sense for real-world riding.

Hot tip!

Before installing, lightly inflate the tube so it holds shape. It makes fitting easier and helps prevent pinching the tube during installation, which is one of the most common causes of fresh punctures.
