The invention discloses a mountain bike riding air guide shield device and a working method. The mountain bike riding air guide shield device comprises a crankset rotating wheel which is installed on the outer side of a crankset and rotates together with the crankset, and an adjustable air guide plate is installed on the edge of the outer side of the crankset rotating wheel; the upper edge and the lower edge of the adjustable air deflector are arc-shaped, the arc length of the adjustable air deflector is 1/5-1/3 of the arc length of the edge of the outer side of the dental disc rotating wheel, and the curvature of the adjustable air deflector is the same as that of the edge of the outer side of the dental disc rotating wheel; the rear side of the upper edge of the adjustable air deflector intersects with the rear side of the lower edge of the adjustable air deflector, and the front side of the upper edge and the front side of the lower edge are far away from each other and form the front edge of the adjustable air deflector. A plurality of air guide protrusions protruding towards the inner side of the adjustable air guide plate are evenly distributed on the adjustable air guide plate, front openings of the air guide protrusions form air guide holes penetrating through the adjustable air guide plate, and the included angle between the connecting line between the center of each air guide protrusion and the center of the tooth disc rotating wheel and the opening direction of the air guide protrusion ranges from 70 degrees to 110 degrees.
