How do you replace the inner tube on a bike?

To replace the inner tube on a bike, first remove the wheel from the bike. Use tire levers to take off one side of the tire and remove the old tube. Insert the new tube into the tire, making sure it is properly aligned. Carefully reinsert the tire onto the wheel, ensuring the tube is not pinched. Inflate the tube to the recommended pressure and reattach the wheel to the bike.
