Introducing the MAKELEN 2 Pack Fat Tire Tubes, specifically designed for electric bikes and mountain bikes. These tubes are sized to fit 20×4.0 and 26×4.0 tires, offering a perfect solution for your biking needs. The tubes feature a 32mm Schrader valve (AV), ensuring compatibility with most standard rims.

Made from high-quality rubber material, these inner tubes are elastic and resistant to punctures. This durability is essential for riders who face diverse terrains. The reinforced side wall contributes to stability after inflation, effectively preventing tire blowouts that can disrupt your ride.

Installation of the MAKELEN inner tubes is a breeze. They fit wheels sized at 700/29’/27.5′, but it is crucial to confirm compatibility with your specific bicycle tires before purchasing. The standard 35mm Schrader valve allows for easy inflation, making it convenient for any cyclist. When inflating your tires, be sure to follow the provided inflation guide to achieve optimal performance.

Replacing old or damaged inner tubes can save you time and enhance your biking experience. With our MAKELEN tubes, you can replace an old tire inner tube in just a matter of minutes. This efficiency ensures that you spend more time enjoying the ride rather than dealing with mechanical issues.
