Stromberg Carlson 120 lb Capacity Made in the USA BC-108 Four Bike Post Mount Carrier

A heavy-steel platform rack that hauls four bikes on any RV, SUV, or trailer with a 1-1/4" or 2" receiver hitch. It tilts away from the vehicle for rear access, collapses flat when not in use, and ships with every piece of hardware needed for a full installation.

Four Bikes. One Rack. Built for the Road.

The Stromberg Carlson BC-108 is a platform-style post mount bike carrier engineered for RV owners who want a no-nonsense solution for transporting up to four bicycles. Whether you are heading to a trailhead in your motorhome, towing a fifth wheel to a state park, or loading bikes onto an SUV, the BC-108 fits the receiver hitch you already have and handles the weight you need.

Unlike hanging-style racks that let bikes swing and rattle, the BC-108 cradles each bike on individual post arms, keeping frames stable and reducing road vibration contact. Heavy-gauge steel construction and zinc-plated hardware mean this rack is built to last through seasons of use.

Dual Receiver Fit

Mounts in standard 1-1/4" or 2" receiver hitch openings -- covers the vast majority of RVs, SUVs, and trailers without an adapter.

120 lb Load Capacity

Rated to carry up to 120 lbs total across four bike positions, accommodating most adult bike combinations.

Tilt-Down Access

The entire rack tilts down so you can reach your RV rear storage, tow vehicle trunk, or trailer access door without unloading the bikes.

Collapsible Storage

Folds down compactly when not in use -- no need to remove it from the hitch between trips or store a bulky disassembled rack.

Mounting Flexibility

The BC-108 can be mounted on the top or bottom of a bumper-style hitch, giving you flexibility based on your rig's hitch height and rear clearance. This is particularly useful on travel trailers and fifth wheels where hitch receiver placement varies by manufacturer.

RV Application Note: Post mount racks like the BC-108 are popular on Class A and Class C motorhomes, fifth wheels, and travel trailers where towing a separate trailer is not needed. Confirm your hitch receiver is rated for accessory (non-towing) tongue weight before installing any bike rack.

Construction and Hardware

The carrier is fabricated from heavy steel with zinc-plated hardware to resist corrosion on the road. At 17 lbs, it is substantial enough to feel solid but manageable for one person to install or remove. Assembly requires a 3/4" wrench (sold separately), and all mounting hardware is included in the box -- no extra trips to the hardware store.

Complete Out of the Box: The BC-108 includes all hardware necessary for a full installation. No additional fasteners or adapters are required for standard 1-1/4" or 2" receiver fitments.

Assembly and Tools Required

  • Recommended tool: 3/4" wrench (sold separately)
  • All mounting hardware is included
  • No drilling or vehicle modification required for standard receiver hitch installation
  • Top or bottom bumper mount orientation selectable at assembly
Maintenance Tip: After installation, periodically check all bolts and the hitch pin for tightness, especially after the first 50 miles of travel. Road vibration can work fasteners loose on any receiver-mounted accessory. A light coat of anti-seize on the shank will make seasonal removal easier.

Warranty and Origin

The BC-108 is backed by a 1-Year Manufacturer Warranty from Stromberg Carlson and is Made in the USA.

Important Information
  • Not designed for towing. This is an accessory carrier only. Do not attach a trailer or tow any load from this rack or the vehicle's hitch while the BC-108 is installed.
  • 120 lb maximum total capacity. Do not exceed the combined bike weight limit. Overloading can damage the rack and the hitch receiver.
  • Verify your hitch receiver's accessory weight rating before installation. The hitch itself must be rated to handle the tongue weight of the loaded rack. This is separate from the rack's own 120 lb rating.
  • Not a locking rack. The BC-108 does not include an integrated lock for bikes or the hitch pin. Use separate bike locks and a hitch pin lock (sold separately) to secure your load.
  • Check clearance before driving. Confirm the loaded rack does not contact the ground, the vehicle body, or obstruct brake or turn signal lighting. A rear light bar may be required to maintain legal visibility depending on your state or province.
  • Tighten all hardware before every trip. Road vibration can loosen fasteners over time.
