Abstract: A system and mechanism for lifting and lowering bicycles onto the roof of an automobile or other vehicle. A lift arm containing support brackets for holding the bicycle is fixedly attached to a rotatable shaft member positioned on the roof of the vehicle. The shaft member is secured to a bearing member at one end and a gear set mechanism at the opposite end. A crank arm member or motorized mechanism is utilized to operate the gear mechanism and rotate the shaft member. Rotation of the shaft member in turn rotates the lift arm member and lifts and lowers the bicycle onto and off from the roof of the vehicle. Support members for holding the handlebar and seat of the bicycle are attached to the lift arm member for securing the bicycle to it. When the bicycle is in position on the roof of the vehicle, additional bracket members secure the wheels to the vehicle.
