  • Folds flat against the vehicle and tilts down 30 degrees to allow for hatch access

    What can I add?

    Posted by Heinrich Hurtz on Sep 3rd 2019

    All the existing reviews leave me with very little to add. Great function, great value, easy to use and rock solid with our two mtbs on it. My previous fully functional rack of 10 years got destroyed in a car accident. I researched a lot of racks, including the justifiably vaunted 1Up but was already familiar with Rockymounts and decided the Monorail would certainly meet our needs. I ordered it on-line and picked it up at their store/warehouse in Boulder the same day. (They'll soon be moving to Grand Junction which would be way longer drive for me.) I'm completely satisfied with the purchase. Like for my old rack, I keep a 3/8" drive ratchet handle and 3/4" socket in the car to attach and detach the rack. The 3/4" socket fits the 19mm bolt head better than a 19mm socket.

    Absolutely Bomber

    Posted by Rod Kramer on Jul 2nd 2019

    The RM guys have a winner in this new hitch rack. It went together easily and is massively solid for a relatively lightweight rack. Even heavier bikes lock down with two simple points of contact and stay put even on rough roads. Effortlessly folds up and down. Additionally, this rack is a great value if you shop the rest of the available offerings. I got it in two days even though I live in the boonies on the Oregon Coast. 5 STARS ++

    If only.....

    Posted by Vince on Jun 10th 2019

    I LOVE this rack! super easy to use, great looking. Nice components and easy to use..did I say that?! It's my first hitch/tray style rack and I feel great driving with the bikes on the freeway and around town. Hardly any movement easy to use!'s not made here, sadly. Thanks for the great product though and I hope it lasts for years to come! oh, and customer service is fantastic! Thanks for replacing that part messed up in shipping so quickly.

    Simple to assemble and mount. Tools included, but a 19mm socket wrench makes it easier. Directions indicate a 6mm Allen key (included too) but the screw heads and key are actually 5mm. Rack is snug, no rattles. So easy to mount bikes. So far 23mm 650s, 25mm 700c and 3" mid fats in the rack - like it was built for each. Thanks RockyMounts. Fits great, looks great and simple to use. Fits the TSX Wagon like a charm.

    Doesn't clear my Mastodon

    If you have a kick arse fat bike carrying hitch rack, shouldn't it not bang into the fork itself????

    Way Better Than a Thule T2

    Posted by Bobby Merrill on Sep 25th 2018

    I originally had a Thule T2 bike rack which got the job done but always felt like it was kind of cheesy. This rack is amazing, it has a high quality build and folds up super compact against the trunk compared to the Thule. The angled wheel trays are super intuitive so you don't have to adjust the position depending on the size of your bike like you have to with the Thule. The only thing I like better about the Thule is it has cable locks built in to the load arm but that's really just a convenience. Super impressed with the quality you get for the price you pay. Definitely will be back in the future for all of my rack needs.

    Works great with my 4.7" fatbike

    Posted by Randy Borst on Sep 16th 2018

    I gave my Monorail rack a test run on an over 400 mile road trip with a 4.7 Farley fatbike on back. It works wonderfully and held on perfectly. The ability to tip it to gain access to the tail of my Crosstrack is great too. My only suggestion is a better lock for the rack and cable. It'll keep the honest people honest, but not much beyond that. Overall very satisfied.

    From Box to Bike in No Time

    Posted by smurph on Sep 5th 2018

    This rack is a breeze to set up. Lay out materials, back up the truck and go to town. They provide everything you need including wrenches, locks and cable. I had to shim with some small wedges of wood to get it extra stable, but that is just because of the slight play in the 2" receiver. No biggie. It took less than 30 minutes to have the rack set up and bikes loaded. Also find that taking bikes on and off is super easy as well. This rack is a phenomenal value and guys at the RM were totally helpful along the way.
