Thule Insta-Gater Truck Bed Bike Carrier - The Insta-Gater Truck Bed Bike Carrier by Thule lets you turn your pick-up truck bed into a versatile bike carrier, with no drilling or bolting required.

It fits 20 to 29 inch wheel diameters, up to 3 inch wide tires, and most bikes with disc brakes, and a 1 One-Key lock cylinder (sold separately) locks your bike to the carrier. The Thule Insta-Gater Truck Bed Bike Carrier is a quick and easy way to secure your bicycle in the back of your pick-up.
