How to Quickly and Easily Put a Back Wheel on a Mountain Bike
To put a back wheel on a mountain bike, first, shift the bike onto its handlebars and seat. Loosen the nuts on the wheel, remove the old wheel, and slide the new wheel in, making sure it is properly aligned with the frame. Tighten the nuts securely on either side of the wheel, and then turn the pedals until the chain is firmly in place. Finally, test the wheel to ensure it is properly attached and secure before riding.
