Introducing the ultimate solution for your biking needs: our 2-PCS 20′ Heavy Duty E-Bike Tubes. These inner tubes, specifically designed for 20×3.5 and 20×4.0 bicycle tires, are crafted from high-quality butyl rubber, ensuring exceptional performance and reliability for every ride.

Each tube measures 20”x3.5”/4.0′ and features an AV32MM Schrader valve, making them compatible with a wide range of fat tire bicycles. One of the key attributes of these inner tubes is their heavy-duty construction, which enhances the ductility and durability of the tire. This means they can withstand harsh conditions and heavy loads, expanding their application scope significantly.

What sets our inner tubes apart is the upgraded thickness which makes them 25% heavier than ordinary tubes available on the market today. This enhancement significantly boosts their durability, making them ideal for consistent riders who value quality.

Moreover, the exceptional shock absorption capability of these heavy-duty tubes ensures that you experience a smooth ride, even on bumpy or rough surfaces. The high-quality butyl rubber acts as a perfect shock absorber, reducing the vibrations that can be uncomfortable and distracting during your ride. Comfort is our priority, and we aim to provide an unparalleled riding experience.

In terms of installation, our inner tubes are designed for ease of use. Before installing, we recommend that you inspect the inner tube by submerging it in water. If you notice any bubbles, it indicates damage, and you should reach out to us for assistance. Additionally, ensure that the valve position is correct during installation to avoid any issues.

Safety is crucial, and we advise keeping the inflatable inner tube away from sharp objects to prevent punctures. Our commitment to quality means that we listen to customer feedback to continually improve our products and services.

As part of our dedication to customer satisfaction, we offer a 1-year warranty on our products. If you experience any issues, please provide evidence and a description of the situation so we can respond quickly. Your time is valuable, and we strive to ensure your complete satisfaction.
