1. A bicycle rack system, comprising:
a first and a second wheel tray affixed to a first edge of a roof of a vehicle, the roof having a width and a length, the first and the second wheel trays spaced apart along a direction of the length of the roof to match the wheelbase of a bicycle to be carried in the bike rack; a support arm extensible and retractable in length, supported by a pivot mechanism near a second edge of the roof of the vehicle, at a point along the length of the roof and oriented such that the support arm lowered to the roof will lie across the width of the roof substantially centered between the first and second wheel trays, the support arm extensible to a maximum length substantially greater than the width of the roof, and a specific length substantially less than the width of the roof; and a capture mechanism on a free end of the support arm, adapted to capture a part of the bicycle to be carried in the bike rack; wherein, with the support arm pivoted downward to lie across the width of the roof, and extended such that the capture device is presented over the edge of the roof, the user is enabled to lift the bicycle to connect the bicycle to the capture device, lift the bicycle further, causing the support arm to pivot upward, place and secure the bicycle wheels in the first and second wheel trays, and cause the bicycle to lean away from the first edge of the roof, causing the support arm to retract. |
