Thule's Insta-Gater turns your truck bed into a stable and secure bike carrier. It mounts without tools because it is ingeniously held firmly in place by closing your truck's tailgate on the ends of the mounting straps. This unique bike rack accepts one bicycle with 20- to 29-inch wheels and up to 3 inch wide tires. And, it's easy and fast to mount your bike thanks to Thule's SecureHook that holds the bike by grabbing the front wheel. No frame contact is made. You can also use more Insta-Gaters to carry more bikes.
