Thule 599XTR Big Mouth

The Big Mouth bike carrier is a tried and true design for upright bike carriers. A great rack for the whole family, especially kids bikes without a quick release front wheel. The super secure clamping mechanism is set low making it easy to get to when loading bikes, especially on a tall roof.
