If you ride a fat bike with wide 26-inch tyres, the Fat Bike Inner Tube gives you a straightforward replacement when your existing tube needs changing. Designed for 26 x 4.0-4.9 fat bike tyres, it helps get your bike back to the correct tyre pressure so you can get back to comfortable, controlled cycling.

The wide size range makes this tube a handy option for fat bikes used on sand, trails, dirt tracks and general cycling. It is also popular for e-bikes, making it a practical spare to keep at home or carry with you when cycling further from home.

Made for Wide Fat Bike Tyres

With a 26 x 4.0-4.9 size, this inner tube is designed specifically for the large-volume tyres found on fat bikes. It suits cyclists who need a tube that matches the wider tyre casing rather than a standard 26-inch bike tube.

Suitable for Fat Bikes and E-Bikes

This Chaoyang inner tube is a popular choice for both traditional fat bikes and e-bikes fitted with compatible 26-inch fat tyres. It is particularly useful for cyclists who put extra kilometres into their e-bike or regularly cycle on surfaces where punctures can happen.

Schrader Valve with 33mm Stem

The 33mm Schrader valve is the familiar car-style valve found on many fat bikes and e-bikes. It makes inflation simple with a standard Schrader-compatible pump or compressor, while the 33mm stem provides suitable clearance through the rim.

Air Leakage Tested

Each tube undergoes a 100% air leakage test as part of Chaoyang’s quality control process. That gives you added confidence when fitting a new tube to your fat bike and getting your tyres back to the correct pressure.
