Pivotable bicycle rack

Abstract

A bike carrier that retains the wheels of a bike in a tray between pivoting retention arms with ratchets that hold the arms against the tires. In embodiments, a retention arm pivot lock acts on a stay between each wheel retention arm and the tray to which it is attached, wherein the pivot ratchet is configured to allow the wheel retention arm to pivot through a reflex angle to provide inward pivoting of the wheel retention arm and outward pivoting of the wheel retention arm to provide a frame for a ramp to allow the bike to roll onto first and second wheel trays. In embodiments, the carrier comprises a rotational pivot assembly configured to pivot the bike carrying tray assembly among a horizontal position, a first downward position and a second downward position.
