The invention relates to a carbon fiber bicycle rack. The carbon fiber bicycle rack comprises a transverse beam (2), a seat tube (4) and a seat stay (8). The carbon fiber bicycle rack is characterized in that a rotary connection part (3) which extends towards the rear oblique upward side and is bifurcated in a Y shape is formed at the rear end of the transverse beam (2); the top ends of two tubes of the seat stay (8) are respectively and fixedly connected with the rear ends of two branch tubes of the rotary connection part (3); the upper end of the seat tube (4) is embedded in and fixedly connected to a position between the two branch tubes of the rotary connection part (3); an included angle a between the plane of the center lines of the two branch tubes of the rotary connection part (3) and the center line of the seat tube (4) is 115-120 degrees; an included angle b between the plane of the center lines of the two branch tubes of the rotary connection part (3) and the center line of the transverse beam (2) is 144-148 degrees; an included angle c between the plane of the center lines of the two tubes of the seat stay (8) and the center line of the seat tube (4) is 58-62 degrees. The bicycle rack adopting the technical scheme provided by the invention has an excellent suspension effect.
