Abstract: A bicycle saddle structure includes a saddle portion having two elastic supporting bodies in a bottom surface thereof and a nose position pivoted to the saddle portion, the elastic supporting bodies are circular spiral-shaped, which can provide a buffer force to the rider, so as to improve the riding comfort. The nose portion can be selectively located at the same level as or vertical to the saddle portion via a pivoting unit, the saddle can be changed to the nose-shaped saddle or the saddle without nose portion, so as to improve the applicability.
