How to Change Inner Tube on Mountain Bike: A Step-by-Step Guide
To change the inner tube on a mountain bike, start by removing the wheel from the bike. Next, use tire levers to remove the tire from the rim and take out the old inner tube. Insert the new tube into the tire and align the valve stem with the hole in the rim. Carefully push the tire back onto the rim, making sure the tube is not pinched. Finally, inflate the new tube and reinstall the wheel onto the bike.
