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. The retention arms are quickly adjustable for different sized tires without tools. An embodiment provides a bike wheel main tray assembly pivotally mounted on a trailer hitch drawbar at an operational horizontal position and a compact vertical position selectable via a trigger at the back of the tray assembly. The main wheel tray assembly has a tray for each wheel of a bike. The two trays pivot between a compact position for shipping and storage and an operational position that is automatically locked. An add-on tray assembly provides wheel trays for a second bike. It connects to the main tray assembly without tools, and provides a trigger at the back connected to the pivot selector of the main tray assembly.
