It All Adds Up.

Expand your 2-inch receiver MonoRail hitch rack from its stock 2-bike set-up to a three bike rack with the MonoRail Single Bike Add-On. The kit provides everything you need to add additional carrying capacity to your MonoRail. Each carrier offers 3-inch side to side adjustability creating optimal bike offset if needed.

The base 2-Bike MonoRail supports 120lbs in total with a 60lbs max per tray. With the 3-bike set-up afforded by this Single Bike Add-On, the max load is still 120lbs and it can hold wheels ranging from 20 to 29-inches and tires up to 5" wide. Quit bailing out of doing shuttles and driving to the trailhead by bolting up the Add-On to your existing 2-inch MonoRail.

  • Extend your MonoRail to 3 bike capacity with this add-on
  • Includes carrier and fittings to add to existing rack
  • Fits 20-29-inch wheels and tires up to 5-inches
  • Not compatible with 1.25-inch MonoRail racks

Just as Good as the Main Rack

  • Familiarity: I've used it several times

This piece adds versatility to the standard 2" Monorail rack. We do not always need to haul 3 bikes on the back of the car so it is only installed when the need arises. It takes less than 2 or 3 minutes to remove the rear cap, slide this in, install to retaining bolts, and reinstall the cap. Not something you want to do every day but to do it once every week or two is not an issue. Or you can just leave it on. And once it is installed it is sturdy without any extra wobble. We are also thinking of getting a single Monorail for our car and this can be used with that too. Definitely recommend if you are considering it.

Best rack system I have ever owned

  • Familiarity: I've put it through the wringer

This may just be the ad on part to the Rocky Mounts Monorail. But it sure is a quality piece of machinery I have had this rack for about two years now and I wouldn’t buy anything else for the price point and the durability.
