The carrier (10) is made up of a lower folding portion (19), an upper folding portion (14) and a fixed portion (13) comprising two U-shaped side parts (15) fixed to the body (11) of the recreational vehicle. The lower folding portion (19) includes rails (24) and straps (25) to receive bicycle wheels, the upper folding portion (14) comprises a U-shaped part (26) with an articulated arm (32) with sleeves (35) and belts (36,37) to fasten bicycles to the arm.
