Heavy-Duty Performance: Kenda 26" Fat Tire Inner Tube

Keep your adventure moving with the Kenda 26x4.0 Fat Tire Inner Tube. Engineered to handle the unique demands of high-torque E-Bikes and heavy-duty mountain bikes, this tube is constructed from high-quality butyl rubber for superior air retention and puncture resistance. Whether you are commuting on urban pavement or exploring rugged off-road trails, Kenda’s reliable construction ensures you spend more time riding and less time fixing flats.

Key Features

• Premium Butyl Rubber: Formulated for high elasticity and durability, providing a consistent seal and resisting "pinch flats" during low-pressure off-road use.
• 32mm American Schrader Valve: Features a standard straight reinforced valve stem, compatible with all gas station air pumps and standard bicycle floor pumps.
• Wide Expansion Range: Specifically designed to fit tire widths ranging from 3.5" to 4.0", ensuring a wrinkle-free fit inside most modern fat tire casings.
• E-Bike Ready: Built to withstand the increased weight and heat generated by rear-hub motors and mid-drive E-Bike systems.

Comprehensive Fitment Guide

This tube is a direct replacement for 26-inch Fat Tire models from the industry's leading E-Bike and MTB brands:

Technical Specifications

• Size: 26" x 3.5 / 4.0
• Valve Type: 32mm Schrader (Standard)
• Valve Orientation: Straight

Installation Tip: Fat tire tubes are large and can easily get bunched up during installation.  Slightly inflate the tube (just enough to give it shape) before tucking it into the tire. This prevents "twists" and reduces the risk of pinching the rubber with your tire irons.
