Abstract: A rack positionable within a bed of a pick-up truck for supporting a plurality of bicycles in a parallel, spaced relationship. The rack includes a pair of transverse members positionable against opposed front and rear sides of wheel wells within the truck bed. A plurality of bicycle wheel receiving channels extend orthogonally over the transverse members to support a bicycle within each one of the channels. Each channel is provided with a vertically extending upright member which attaches to the bicycle to support the same in a vertical orientation. Because the transverse members engage front and rear sides of the wheel wells, no additional mounting means is needed to preclude movement of the rack within the truck bed.
