Warm Tips: 

1. Please kindly confirm the size of your bike tire before you buy. 

2. Before inserting the new tube, make sure to check for sharp/pointed objects inside or embedded in the tire, that could puncture the tube. 

3. Add a little air (to give the tube form) to the new inner tube before installation. This will prevent it from bunching up, causing a pinch flat or possibly forcing the tire off the rim. 

4. Place the valve through the hole in the rim. Valve should stick out at a 90-degree angle. Screw valve cap on tightly and securely. 

5. After installation, make sure the tube is fully inside the tire and not pinched between the tire and metal frame. Now you can inflate the tire to recommended pressure levels. Our AV Schrader valve inner tube is perfect for mountain bikes, gravel, city and electric bikes, offering seamless fit and functionality.
