About this item

• 20x4.0 Fat Bike Tubes(2-Pack) with AV35 Schrader Valve - Ideal for Fat Tire Electric Bikes and Mountain Bicycles(Includes 2 Tire Levers)
• Premium Butyl Rubber: Our inner tube, crafted from High-Quality butyl rubber, offers exceptional wear and puncture resistance, superior anti-skid performance, and remarkable airtightness, elasticity, and resistance to aging.
• Effortless Inflation with Schrader Valve: Featuring a standard 35mm Schrader valve, easily compatible with most rims and effortlessly inflated using common bike pumps.
• Elevate Your Ride: Crafted for 20in x 4.0 tires, our inner tube enhances your cycling experience by delivering improved shock absorption and tire stability.
• It is strongly recommended to wear anti-puncture strips for extra protection. While the tubes are thicker, they are not indestructible. If a tip penetrates your tire, your inner tube can be pierced. Before installing, wrap the pointed end of the crowbar with a fiber cloth to prevent damage to the inner tire and coating of the hub.
• When replacing a bike's inner tube, remember to add a bit of air before installation. This helps it take shape, preventing twisting or bunching that could lead to a pinch flat.
