摘要

A rear-mounted bicycle carrying rack for a vehicle is provided, including a base, two supporting racks, two supporting arms, two upper prop racks and a lower prop rack. The two supporting racks and the lower prop rack are pivoted to the base respectively, and the two supporting racks are swingable relative to each other to be V-shaped. The two supporting arms and the two upper prop racks are pivoted to an end of the two supporting racks respectively relative to the base and are behind the two supporting racks. When the two supporting arms swings upward and forward, the upper prop rack is pushed to swing backward, the two supporting arms abut against the two supporting racks to make the two supporting arms and the two upper prop racks extend forward and backward respectively, and the lower prop rack swings backward.
