Platform style bike racks are some of the most convenient bicycle carriers available. With their low height clearance and wide spacing between trays, most bikes can be loaded and unloaded in seconds. Basic platform bicycle racks like the Thule 990xt Doubletrack hold bikes by both tires and frame, and are a great, inexpensive option for smaller vehicles. Other systems like the Yakima 8002443 HoldUp, hold the bikes exclusively by the tires - a "must-have" feature for carbon-fiber bikes or unconventional frames. Remember, when you spend over $99 on hitch or trunk mount mounted platform bicycle racks your order ships free. If you don't already have a trailer hitch, the Thule 9003pro Raceway 2 Bike Trunk Mount Platform Bicycle Rack may be just what you're looking for. If not, be sure to check out our complete line of Curt Trailer Hitches.
