Upgrade your cycling experience with our 20/26×4 Fat Tire Bike Tubes, specifically designed for 20-inch wheels. Crafted from high-quality butyl rubber, these tubes offer excellent air retention and durability, ensuring a reliable and enjoyable ride. Each package contains two 20×4.0 inner tubes and two tire levers to make installation quick and hassle-free.

These premium tubes are equipped with a 32mm Schrader Valve, allowing for easy inflation. The high butyl rubber content provides superior shock absorption, impact resistance, and puncture resistance, making them ideal for various terrains, including mountain trails and sandy beaches. Experience a smooth ride whether you’re navigating rocky paths or cruising along flat surfaces.

When installing your new inner tubes, it’s crucial to follow a few simple steps to ensure optimal performance. First, always confirm the size of your bike tire before making a purchase. This will prevent any compatibility issues that may arise.

Before inserting the new tube, carefully check for sharp or pointed objects inside the tire that could puncture the tube. This is important to avoid damage to your new inner tube. Additionally, adding a little air to the tube before installation helps it maintain its shape, preventing it from bunching up and causing pinch flats.

Next, place the valve through the hole in the rim, ensuring that it sticks out at a 90-degree angle. Secure the valve cap tightly to prevent any air leakage. After installation, make sure the tube is fully seated inside the tire and not pinched between the tire and the metal frame. Once everything is in place, inflate the tire to the recommended pressure levels, and you’re ready to hit the road!

Our AV Schrader valve inner tubes are perfect for a variety of bicycles, including mountain bikes, gravel bikes, city bikes, and electric bikes. They offer a seamless fit and functionality, making them an excellent choice for all cycling enthusiasts. Enjoy your rides with peace of mind, knowing you have reliable equipment to support your adventures.

To ensure the longevity of your tubes, keep in mind that the rubber-coated valve stem features an enhanced seat seal that prevents the entry of sand and dust. This design helps to extend the service life of your valves, allowing you to focus on the joy of cycling rather than worrying about maintenance.

For your convenience, we provide free replacements for any damaged tubes. Simply put them in water before installation to check for leaks—bubbles indicate a problem. Our commitment to quality ensures that you can cycle confidently, knowing your gear is top-notch.
