How do you change the back wheel on a bike?

To change the back wheel on a bike, first, release the brakes and shift the chain to the smallest cog. Then, loosen the axle nuts or quick-release skewer to remove the wheel. Install the new wheel by aligning the chain with the cog and tightening the axle nuts or quick-release skewer. Finally, adjust the brakes and test the wheel for proper alignment and function.
