Dual-bike dream ship.

You can forget about painstakingly loading your bike in the rear hatch when you outfit your vehicle with the RockyMounts MonoRail Platform Hitch Rack. This two-bike carrier conveniently mounts to either 1.25- or 2-inch receiver hitches, giving you the ability to mount it to your smaller car or large truck. For greater capacity on downhill shuttles and family outings, the 2-inch receiver version gives you the option for carrying a third bike with the MonoRail Single Bike Add-On (sold separately).

The sturdy platform design carries up to 120 pounds of total weight, which is considerably more than many hitch-mounted racks in this category. It accommodates bikes with 20 to 29-inch wheels, with tires up to a gargantuan 5-inch width. This gives you the ability to quickly and easily transport bikes ranging from your favorite road bikes to full-suspension mountain bikes, and even the biggest of fat tire bruisers. The adjustable front wheel clamp eliminates the need for frame contact, which is a major plus for riders with carbon frames and sensitive paint jobs. Three inches of side-to-side adjustment gives you ample room to space out bikes, without them contacting each other at highway speeds.

  • Sturdy two-bike carrier for 1.25in or 2in hitch
  • Fits bikes with up to 29in wheels and 5in tires
  • Maximum weight capacity of 120lbs for both bikes
  • 3in of side-to-side adjustment for a proper fit
  • Front wheel hook doesn't make frame contact
  • Adjustable rear wheel strap for security
  • Included bike-to-rack and rack-to-car locks

Unanswered Question

Does anyone have this on a Toyota Tacoma? Does the tail gate clear when the platform is pivoted down? How sturdy does it feel tilted down with some bikes in the trays? Thanks for the help!

RockyMounts MonoRail Platform Hitch Rack

    I had been looking for a nice receiver hitch rack for my Jeep JKU that would not break the bank. After the Competitive Cyclist discount this rack was very affordable. I took a chance on it and could not be more impressed. Easy to assemble, very quick and easy to use, folds up out of the way when not in use. It holds my Trek Fuel ex9 perfectly. Locking system is ok, like most it is meant to be a deterrant only. Very nice quality. I would highly recommend to a friend or family member.

    Decided to take a chance...

    • Familiarity: I've used it once or twice and have initial impressions

    So far, so good! This rack is well built, and very easy to assemble. It handles everything from my road bikes to my fat bike without adapters. I dislike the cable lock system that comes with most racks these days, and this one is no exception. It tightens into the hitch nicely, so there isn't much wobble. If there was a 4.5 star option, I'd select that. If the security system was just a touch better, this rack would earn all 5 stars. Time will tell how well it holds up to Utah's salty roads, but so far, so good!

    Not for Steep Driveways

      First let me say that if you never have to deal with transporting bikes up steep driveways or over uneven ground-- this rack is pretty darn cool! And solid!! I just put mine together. This RockyMounts Monorail is the replacement for a Yakima 2-UP rack gone bad from rust and wear after just 5-years (North Carolina Weather isn't that rugged). BUT I was really sad to learn on my first trip into my driveway that it cannot clear the pavement even without bikes on it. It sticks out too far in back. Yakima overcame this with a curved design for a spine. You can see in the picture what I'm talking about. I'm very bummed. Believe me it's a nice rack in many other ways, but it cannot get up my driveway and Yakima was able to clear easily even with two bikes on board.

      Solid for the money

      • Familiarity: I've used it several times

      Seems solidly built and holds both by road and mtn bikes very securely. It does require a small amount of assembly - probably took me 20 mins to put the wheel trays on. It's nice that it comes with locks for the rack and bikes, but I wouldn't call them very elegantly integrated and the plastic lock housing doesn't inspire great confidence. I'd use a separate cable or u lock if you're leaving it parked anywhere iffy.
