A removable bicycle beam for adapting a bicycle frame for engagement with a vehicle-mounted bicycle rack. The beam includes a pair of securing mechanisms disposed on opposite ends of a central body. Each securing mechanism includes a fixed arm fixedly secured to the central body and a pivoting arm pivotally secured to the central body. Each arm includes a gripping portion extending outwardly from the central body that cooperates with the gripping portion of the other arm to releasably encircle and engage a component of the bicycle, such as the handle bar stem or the seat post. The pivoting arm and fixed arm lie in a substantially horizontal plane when in a closed position, and the pivoting arm is movable in the horizontal plane toward and away from the fixed arm. Each pivoting arm can be locked in a closed, engaged position by one of a pair of releasable latch mechanisms disposed within the central body and engagable with the pivoting arms. The central body is formed of a pair of telescopically mounted tubes that enable the beam to shift the securing mechanisms with respect to one another in order to accommodate bicycles having various lengths between the handle bar stem and the seat post.
