How to Easily Remove the Front Wheel of Your Mountain Bike
To take the front wheel off a mountain bike, first, flip the bike over or place it in a bike stand. Then, release the brake by either pulling the brake caliper arms apart or releasing the brake lever. Next, loosen the quick-release lever by flipping it open and spinning the lever counter-clockwise until the wheel is loose. Finally, pull the wheel out of the dropouts and remove it from the bike.
