Haul two bikes today, four bikes on the next trip -- the Curt 18030 expands to meet your needs without swapping racks. Bolt-on extension arms scale capacity from 2 to 4 bikes, rubber-coated cradles protect every frame, and a tilt-away design keeps your RV's rear door accessible even with bikes loaded.
Whether you're heading out for a weekend of trail riding or loading up the whole family's bikes for a longer trip, the Curt 18030 adapts without making you buy additional hardware. The extension arms bolt on and off in minutes, and when the rack isn't in use the arms fold down and the post disconnects for flat, compact storage in a truck bed or RV basement.
The included adapter sleeve bridges the gap between 1-1/4" and 2" receiver tubes, so this rack works across Class I, II, and III hitches. If you're using a 1-1/4" receiver (Class I or II), the included heavy-duty nylon support strap is required -- it compensates for the lower tongue-weight capacity of smaller hitches and keeps the rack stable under load.
Removable bolt-on extension arms convert the rack from a 2-bike carrier to a 4-bike carrier. No separate rack needed for larger groups.
Adjustable rubber-coated support arms grip bike frames securely without scratching paint or carbon fiber. Works with a wide range of frame tube diameters.
The entire loaded rack tilts away from the vehicle so you can open a rear hatch, camper door, or truck tailgate without unloading a single bike.
Threaded anti-wobble bolt tightens the shank against the receiver walls, eliminating the side-to-side sway that plagues standard hitch racks on rough roads.
The 18030 ships with an adapter sleeve that allows it to seat properly in both 1-1/4" and 2" receiver tubes -- no separate purchase required. This covers the vast majority of tow vehicles and RVs on the road today.
The main structure is steel with a durable black powder coat finish that resists chipping, rust, and UV fading -- important for a rack that lives outside in all weather conditions. Rubber cradle coatings are thick enough to absorb trail vibration without cracking or peeling under repeated use.
The bolt-together post disconnects and the arms fold flat, so the disassembled rack stores in a fraction of the space of a rigid unit. This matters in an RV where basement bay space is at a premium. The nylon strap stores with the rack and doesn't require any special hardware to reattach.
