Abstract: A collapsible rack is provided for installation in the bed of an automotive vehicle, such as a van, pickup truck or trailer. The rack includes a rectangular grate which defines a plurality of bike wheel receiving slots and which is carried between a pair of parallel arms. The arms are rotatably secured to the ends of the grate and to the bed of a vehicle so that the grate can be moved between a collapsed position lying upon the bed of the vehicle and an erected position inclined relative to the vehicle bed to receive the front wheel of a motorized bike. A pair of straps of adjustable length are provided with hooks on both ends to extend between the grate and a motorized bike with a wheel of the motorized bike positioned in one of the slots to hold the motorized bike erect in the bed of an automotive vehicle.
