A motor bicycle rim (2) comprises a basic rim structure (4) out of aluminum alloy which basic rim structure is covered at least in part by a glass fiber and/or carbon fiber reinforced resin layer(6) adapted to the use of an adhesive material designed to bond the reinforced prepreg material to the basic rim structure of aluminum alloy. A method of producing the motor bicycle rim comprises fixing glass fiber and/or carbon fiber reinforcement material to the basic rim structure out of aluminum alloy, providing a prepreg resin to the basic rim structure having glass fiber and/or carbon fiber reinforcement material fixed thereto; and curing the prepreg resin together with the glass fiber and/or carbon fiber reinforcement and using an adhesive material designed to bond the reinforced prepreg material to the basic rim structure of aluminum alloy. Another method of producing a motor bicycle rim comprises fixing glass fiber and/or carbon fiber reinforced prepreg material to the basic rim structure out of aluminum alloy; and curing the prepreg resin together with the glass fiber and/or carbon fiber reinforced prepreg material.
