Update September 24: Picture of fully loaded JackKnife added below the break.
One of several new racks introduced at Interbike this year, Swagman’s Jackknife rack takes hitch rack convention and turns it on its side. The new rack’s vertical orientation allows for tighter bike spacing and a stronger, lighter structure. The bikes (two as shown, four are possible) alternate sides and the slightly twisted front wheel keeps handlebars from interfering. Go behind the bumper for more photos and details.
Shown here folded nearly flat, the Jackknife isn’t particularly deep, keeping vehicle length to a minimum. This configuration also maximizes ground clearance (though bikes could sit a bit high on smaller cars). Finally, Swagman claim that the four-bike Jackknife is a full 20lb lighter than the next non-frame-contact four-bike rack. At $600 for the two bike version, the Swagman is an interesting alternative that we’d love to see in action.
