PURPOSE: A wheel for a bicycle including a protruding blade is provided to improve safety by improving an unstable state of a bicycle body during high speed driving in a strong wind and to increase the driving speed of the bicycle by utilizing the wind. CONSTITUTION: A wheel for a bicycle including a protruding blade comprises protruding blades(12) and an air flow hole(11). The protruding blades symmetrically protrudes to both side surfaces of a rim(10) in a rear wheel(200) or a front wheel(100), and the air flow hole is formed at the rim at regular intervals. The protruding blades receive wind pressure and generate a rotatory force rotating the bicycle. The air flow hole removes the lateral pressure due to the wind blowing in a lateral direction of a driving direction and minimizes the shaking of the bicycle.
