Introducing the ultimate solution for all your cycling needs: the 20/26 x 4.0 Inch Bike Tube. This product comes in a convenient two-pack, ensuring you always have a spare on hand, whether you’re hitting the trails on your mountain bike, cruising on your electric bicycle, or taking your fat beach bike for a spin. The Midcos brand is renowned for quality, and these inner tubes are no exception.

Superior Durability
Crafted from high-quality butyl rubber, these bike tubes offer exceptional shock absorption and high-temperature resistance. This means that even in harsh environments, they maintain excellent toughness and driving stability. As a result, your overall riding experience becomes smoother and more enjoyable. Additionally, the 1.25mm thickness of our inner tubes enhances puncture resistance and durability, reducing the need for frequent replacements.

High Air Tightness
The inner tubes are designed with an advanced butyl rubber compound, which boasts an airtightness that is eight times greater than that of natural rubber. Each tube features a 32mm Schrader valve tip that includes a valve core cap, ensuring a secure seal. The black lever valve cover creates a unique airtight environment that prevents air loss, providing you with the safety and reliability needed for a worry-free ride.

Widely Used
These inner tubes are built to fit most fat tire bikes with 26-inch tires. They accommodate diameters ranging between 3.5′ to 4.0′ (including sizes 26′ x 3.5, 26′ x 3.6, 26′ x 3.8, and 26′ x 4.0). This versatility makes them an ideal replacement kit for various types of bikes, including mountain bikes, e-bikes, gravel bikes, city bikes, and snow bikes.

Convenient Installation with Tire Levers
Included in the kit are two tire levers that simplify the process of removing and installing the bike tubes. These levers make it easy to detach the inner tube from the tire without risking finger injuries, ensuring that tire maintenance is a breeze for riders of all skill levels. To prevent pinch flats when replacing a bicycle inner tube, it’s advisable to add a small amount of air before mounting. This helps shape the tube correctly, preventing twisting or curling during installation.

What You Will Get
Upon opening the package, you will find two 26 x 4.0 inch bicycle inner tubes, two tire levers, and friendly customer service available 24/7. The simplicity of matching parts makes the installation process straightforward, enabling you to replace the tubes by yourself anytime and anywhere. Bring your bike back to life quickly and enjoy the ride!
