Are you tired of flat tires ruining your biking adventures? Look no further! Introducing our astonishing 20′ Self-Sealing Fat Tire Tubes that redefine convenience and durability for your E-bike needs. Designed specifically to fit 20×4.0 and 20×4.5 tire sizes, these tubes are perfect for road and mountain biking enthusiasts alike.

Our self-sealing inner tubes come pre-installed with a special sealant that provides maximum puncture protection. With a thicker design than standard tubes, they offer enhanced durability, making them resistant to both wear and damage. What sets these tubes apart is their remarkable self-repair capability; when punctures occur, the sealant works magic by filling the gap within a mere 5 to 8 seconds under normal conditions.

Comfort is paramount when it comes to biking, and our tubes ensure exceptional shock absorption for a smoother ride. You will not only enjoy the enhanced performance but also the peace of mind knowing that your tires are equipped to handle unexpected issues while on the road.

However, it is important to remember a few essential tips for installation and use:

• To prevent the self-sealing fluid from leaking during installation, avoid placing the center of gravity near the air nozzle when inflating the tube.
• Our self-sealing fluid is specially formulated to resist freezing, remaining functional even in temperatures as low as -15 degrees Celsius. This unique feature makes it ideal for winter biking conditions.
• Please note that while the self-sealing fluid is effective for small leaks, it may not be suitable for repairing larger punctures or tears.
