X-Tech 12 Inch Bike Tube

Finding the right tube for smaller wheels can be tricky, but the X-Tech 12 Inch Inner Tube is built specifically for 12-1/2 x 2-1/4 tyres, a common size on kids’ bikes, scooters, and some prams. Fitted with a standard Schrader valve, this tube is easy to inflate at any servo or with a regular bike pump.

Made from quality butyl rubber, it strikes a solid balance between air retention and flexibility. Whether you’re replacing a punctured tube or keeping a spare on hand, this is a reliable, cost-effective option to keep your wheels turning without hassle.

Who is this for?

This inner tube suits parents looking to maintain kids’ bikes or prams, as well as scooter riders who need a dependable replacement for the rare 12-1/2 x 2-1/4 size. It’s ideal for those who prefer a straightforward Schrader valve and don’t want to overthink the fit – it just works.

Who is this not for?

If your tyre isn’t clearly marked 12-1/2 x 2-1/4, or you’re using Presta valves, this tube likely won’t suit. It also isn’t made for high-performance BMX or off-road use – this is a practical tube for everyday situations, not competitive riding.

Why we love it

Sometimes the hard-to-find sizes are the most essential – and this tube fills that gap. It’s no-nonsense, easy to install, and dependable. We like keeping these in stock for exactly that reason: they’re tricky to find elsewhere but often needed in a hurry.
