INCREASE YOUR BIKE RACK'S CAPACITY WITH QUICK MOUNTING ADD-ONS.
Going Super Duty all the way? Super. With a 3/8'' x 13'' x 1'' added support bar under the tray, the Super-Duty Add-Ons are rated for 50–75 lbs per tray spot. The singular Add-Ons allow for numerical versatility on all the racks. The single-rack carriers are rated for up to three bikes max and the double-rack carriers are rated for up to four bikes max (50–75 lbs per tray spot for the Super-Duty models). Easy on and off with our unique hex wrench. Tighten the two security bolts and we’ll call that installation process sweatfree.
Our easy-to-install Add-On racks give you the versatility to transport multiple bikes on a single rack. So as your family, bike collection, or taste for adventure grows, you can depend on your 1UP USA rack to grow right along with it.
