How do you change a bicycle inner tube?

To change a bicycle inner tube, first remove the wheel from the bike. Then, use tire levers to take off one side of the tire and remove the old inner tube. Insert the new inner tube, making sure it is properly aligned. Carefully reinsert the tire onto the wheel, making sure the inner tube is not pinched. Finally, inflate the tire to the recommended pressure and reattach the wheel to the bike.
