Key Features

• Butyl Rubber Construction: Butyl rubber has lower gas permeability than natural rubber — tubes stay inflated longer between rides, reducing the frequency of inflation and providing more consistent tyre pressure
• 20 × 2.125 Sizing: The 2.125″ width is the standard tyre width for BMX bicycles and wide-tyre children’s mountain bikes — correct sizing prevents the tube from bunching or overstretching inside the tyre
• Schrader Valve: The wider-diameter Schrader (A/V) valve is compatible with standard car pumps, petrol station air points, and most floor pumps — no Presta adaptor required. Confirm your rim valve hole is drilled for Schrader before fitting
• e-Ready Certified: Kenda’s e-Ready marking indicates the tube meets quality and dimensional standards for use on standard and electric bicycles
• Kenda Brand: Kenda is a globally recognised tyre and tube manufacturer, supplying OEM and replacement products to the international bicycle market since 1962

Application Instructions

1. Remove the wheel from the bicycle and deflate the tyre completely
2. Use tyre levers to unseat one tyre bead from the rim
3. Pull the valve through the rim valve hole and remove the old tube
4. Inspect the inside of the tyre and rim tape for the cause of the puncture — remove any sharp objects before fitting the new tube
5. Partially inflate the new Kenda tube just enough to give it shape
6. Insert the valve through the rim valve hole and tuck the tube evenly inside the tyre
7. Re-seat the tyre bead onto the rim — work from the valve outward to both sides
8. Inflate gradually and check the tyre is seated evenly on both sides before reaching full pressure
9. Inflate to the recommended pressure marked on the tyre sidewall
10. Refit the wheel to the bicycle and check brake alignment before riding
