A clipless bicycle pedal including an axle, connectable to a bicycle crank arm, and a locking mechanism, connected to the axle, suitable to engage/disengage a cleat assembly of a cycling shoe. The locking mechanism includes a sleeve, inserted along the axle, an inner loop and an outer loop, inserted along the sleeve and free to rotate around the sleeve, so that the inner loop is contained within the outer loop. The locking mechanism further includes a cam, included between the inner loop and the outer loop, suitable to hold the inner loop and the outer loop in an engagement configuration of the cleat assembly. The cam is also suitable to allow rotational movement of the inner, outer loops relative to each other, from the engagement configuration to a disengagement configuration of the cleat assembly.
