Thule Locking Bed-Rider Add-On Block $74.95
The more, the merrier.
The Thule Locking Bed-Rider Add-On Block will enhance your Thule 822 Bed-Rider and allow it to carry one more bike—say, if you pick up a hitch-hiking biker or something. The simple design lets your friend easily clip the fork of his bike to the fitting. It also includes a lock to secure it to the existing rack.
