Rotating Arms with Ratcheting Hooks

RockyMounts MonoRail 3 Bike Rack Adjustable Arms

The MonoRail has ratcheting hooks that grab your bikes firmly by the front wheel - not the frame. It's perfect for carrying carbon bikes or bikes with a custom paint job. To load a bike, simply place your front wheel in the cradle, rotate the arm up and over the wheel, and press down firmly on the ratcheting hook.

Pivoting Rear Wheel Cradles with Ratcheting Wheel Straps

RockyMounts MonoRail 3 Bike Rack Wheel Straps

The rear wheel cradles accommodate a wide variety of bike wheelbases. They pivot front to back, adjusting automatically to each bike's wheelbase - no need for sliding and tightening. Secure the wheels in place with the built-in ratcheting strap. The straps also include extenders for use with fat bikes.

Adjustable Bike Trays

RockyMounts MonoRail Adjustable Bike Trays

The front and back trays adjust 3" side-to-side to ensure you have enough space when loading your bikes. Just remove the bolts where the tray attaches to the bottom of the rack, slide the trays left or right to achieve the desired spacing, and then reinstall the bolts. This will prevent your bikes' handlebars from becoming tangled, and it eliminates bike-to-bike contact.

Front-Mounted Release Lever for Easy Tilting

RockyMounts MonoRail 3 Bike Rack Tilt

The front-mounted release lever allows you to easily tilt the MonoRail. The rack tilts down - with or without bikes loaded - so you can access your vehicle's rear cargo area. Because the tilt-release lever is located at the front of the rack, you don't have to worry about crawling through bikes or squeezing between the rack and the vehicle to pull it. When you raise the rack back up, you'll hear a click to indicate it's secure.

RockyMounts MonoRail 3 Bike Rack Folds Up

When the rack is unloaded you can pull the lever to fold it up for storage. This means you don't have to remove it to park in small lots at the trail head or in cramped parking garages.

Easy Installation

RockyMounts MonoRail Hitch Mount Bike Rack

It installs with a threaded, anti-rattle hitch pin. Simply slide the shank into your 2" hitch receiver, insert the threaded hitch pin, and tighten it down with the included tool. This will reduce noise and movement while the rack is installed.

Complete Security

RockyMount MonoRail Built-In Cable Lock

Included locks secure your bikes to the rack and the rack to your vehicle. The integrated cable lock threads around your bikes' frames and inserts into the lock that slides along the cable.

RockyMounts MonoRail Hitch Lock

The hitch lock simply snaps onto the hitch pin and locks in place. The cable and hitch lock are keyed alike, so you'll only need 1 key for both locks.

This lightweight, 3-bike rack is perfect for carrying e-bikes, fat bikes, or bikes with a carbon frame or custom paint job. Front bike position can be easily removed if you only need to carry 2 bikes.


This is a really well-made rack that much sturdier than my last hitch-mounted rack. My only concern, before purchasing, was whether or not the 3rd bike, because of its distance from the hitch, might put too much of a load on my suspension, but my 2020 Outback only squatted a 1/2" or less with all 3 bikes loaded. (Note: the bikes are roughly 30 pounds each. See pics.) I only wish that RockyMounts would have included better locks. I know that locks only keep casual thieves from stealing, but these are really, really cheap. This likely isn't as problematic for the hitch pin (which is hard to see/get to) as it certainly is for the locking cable pin--which is much more visible. Still, this one shortcoming aside, I'm very, very pleased with this purchase. Plus, and I know this might not be the best reason to buy the rack, but it looks really nice in the folded-up position. Finally, I really appreciated the wonderful videos and email answers provided by, which helped me understand the numerous racks and pick the one that best fits my needs.


Poor quality. It doesn't securely lock the screw bolt.
The nut which is attached in front tire guard is spinning with a screw bolt and it grinds it's hexagon shape hole.

RockyMount makes a quality, full-featured bike rack at a very reasonable price.

Rack accommodates any size tire, carries 3 bikes (extender for third bike included, as shown), bikes lock down tight and don't move much on dirt roads, rack tilts up easily when not in use, and down when loaded in order to access trunk, comes with a detached cable that can be locked to the frame, and a keyed security nut that locks the rack to the hitch receiver.

I am very happy with this bike rack. It pairs very well with my Curt Trailer hitch and my 2016 Hyundai Tucson.

Great package from, and they were one of the more outstanding online retailers I've ever dealt with. They have my business now.

Second mountain biking season and this rack is great. Figure Ill still be hauling our bikes on it in another 10 years. It will probably last longer than several cars! Thanks for your great service and really tight operation. My review and recommendations stand, 100.


Quick and easy installation. Good quality material....


Missing a part after shipment but customer service was great and resolved the problem quickly.


Really like this bile rack, it is easy to put on the hitch, hold the bikes secure and like the handle to raise the hitch up. Hitch had a cracked brace but call Rocky Mount and sent a replacement part.



After a year still love this bike rack it is easy to install and like the way it hold the bikes


Perfect for a small family and fat bike enthusiasts. One of the few models that fit fat tires and our budget. We've had other RockyMounts products and always liked them.


Awesome rack! No complaints whatsoever. I would have liked the rack to have integrated cable locks like the more expensive racks but I'm cheap and could not see spending more money for that feature. The cable lock that comes with this unit is very good for it's intended purpose. I transport two road bikes and two kids bikes with this rack. I worried alittle about the exhaust heat melting my carbon wheels but it has not been an issue as it seems the exhaust is not even close enough to do that. I have a Hyundai Palisade and a Chevy Silverado I use with this rack. Bikes are very secure and very little movement while secured in the rack. It might be a little heavy for some users but I'm 5' 8" and fairly strong for a 52 yr old. Rack was very easy to put together and I bought the 2 bike additional rack. I have a lot of confidence in this rack and am the type who is very conscious about whether a rack would compromise the condition and aesthetic of my bike or not. So, to sum it up I wanted a solid rack to transport my carbon fiber road bikes and my kids' bikes to various organized rides. I didn't want to give up my left arm to get it and I wanted to be easy to work with. This rack did all that and more.


This is the second hitch I have bought from Etrailer. Great prices, great products and free shipping! I received my 2" Draw-tite hitch for my 2020 VW Tiguan SEL R-line. The hitch fit perfectly with no real installation problems. If you have a Tiguan you may need to shave some of the undercoating near the bolts to make installation easier. I also only cut a 3" x 3" square for the hitch to fit through on the rear bottom valance. It's not necessary to cut a 3" x 6" rectangle. The 3" x 3" square makes a much better appearance. There are two plastic screws you can take out which will let you pull the valance down so the hitch can fit through.

I also purchased the 2" Rockymounts Monorail 3 bike hitch rack. Some assembly but took about 20 minutes. This is really a great hitch rack! Very well made and they supply all the locks etc. I like it much better than the older version of the Kuat Sherpa 1 1/4" hitch rack that I had.

If you need a hitch or a bike rack look no further than Etrailer!


We love the rack but when traveling we have to tighten the bolt that connects the extension to the existing rack. It comes loose


This is very solid, no rattling. It's very easy to mount the bikes too. With a bike only in the second rack the tailgate on our X1 opens.


So far so good! I haven't loaded bikes yet but it is put together and on the car! I won't be storing it on my car because my backup camera beeps nonstop with it attached to the car.


This bike rack is the easiest to load and unload bikes that I have ever used. I highly recommend!


Very solid rack. I like it better than Yakima, Thule and Kuat. It works great and was super easy to install.


I have only had this product for a few weeks, but have used it about 4 or 5 times. So far it has worked really well. It feels sturdy and the bikes are very easy to get on and off.


Everything seems good except price is high like every other rack, but paint seems soft. We'll see if it rusts.









At age 75, I have purchased many bike racks over the years…..this one has no equal in loading and unloading…


This rack is really, good. The only thing i add to make it better is small strap that holds the front wheel to the front wheel bracket. I never had a problem with it, but i like to make sure it is secure. It is a solid bike rack and worth every penny. I would buy this over the Kuat version any day.

  • Can I Transport 1 49-Pound Bike on the Kuat Transfer V2?
    I have a solution for you. For bike racks that have a maximum per-bike weight capacity, each individual bike cannot exceed that single weight capacity on the rack. Loading a 49-pound bike on the Kuat Transfer V2 Bike Rack for 3 Bikes - 2" Hitches - Wheel Mount # KU24FR would be over that limit. With that being said, a great solution is the RockyMounts MonoRail Bike Rack for 3 Bikes - 2" Hitches # RKY10004-10005. the Monorail comes with a 60-pound maximum weight capacity when the add-on...

  • Bike Rack Solution to Carry Bikes with Wider Carbon Frames
    The cradle width the zip straps you mentioned is designed to fit is 1-3/4 inches wide so it doesn't look like the # Y63KV would work for you. Since your bike is carbon you really don't want to use a hanging bike rack anyway since they can damage the frame since carbon is a much more fragile material. You will want to use a bike rack that only touches the bike by the tires like the RockyMounts MonoRail part # RKY10004 for a 2 bike or part # RKY10004-10005 for a three bike.

    I have a great 3-bike option for you. However, the Thule EasyFold XT # TH903202 is not available as a 3-bike option. If you are looking for a ramped solution to carry 3 bikes, the best option is to use the Kuat NV 2.0 Base Bike Rack for 4 Bikes - 2" Hitches - Wheel Mount # BA22B-BA02B (matte black), NV22G-NA22G (gunmetal gray), or # NV22B-NA22B (metallic black).

  • Recommended Hitch and Bike Rack for 2020 Honda Odyssey
    For a hitch for your 2020 Honda Odyssey I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # 76170. This hitch has a concealed cross tube so it will have a clean look once installed on your van. This also means you will have more clearance, which is important since the van already sits pretty low. For the bike rack, a 2-3 bike conversion is going to be as good as it gets. The RockyMounts MonoRail # RKY10004-10005 is a good option that already comes with the 3rd bike add-on. It...

  • What Is Needed To Be Able To Carry 2 or 3 Bikes With a Receiver Hitch For a 2021 HRV?
    Yes, you can use the Curt Trailer Hitch Receiver # C11416 on your 2021 Honda HR-V LX, to be able to carry 2 bikes. This receiver will fit all trim levels and both the FWD and AWD drive types. As you are going to be carrying a bike rack an important measurement is the hitch pin center to bumper measurement which we find to be 5" when installed in our shop. Curt does require the use of their Cam Buckle Stabilizing Strap # 18050 when using any hitch mounted carrying accessory. You must...

    While the RockyMounts MonoRail Bike Rack for 3 Bikes - 2" Hitches # RKY10004-10005 is a superb choice for a Tesla Model 3, I verified that it is not rated for use behind an RV, including motorhomes (it had been at one time but RockyMounts has recently changed this). There isn't a 3-bike rack similar to the MonoRail that can be used behind a motorhome, the only other option for a 3-bike rack is a hanging rack, the Swagman Trailhead 3 Bike Rack # S63365.

  • Can Saris Bones EX 3 Bike Rack Be Used for 45 lb Bike on a 2023 Kia Soul
    The cradles on the Saris Bones EX 3 Bike Rack # SA803 are the limiting factor when it comes to weight so even if your other bikes are lower than the individual weight capacity, the 45 lb bike will still overload that one cradle set and we want to avoid that. For your application I recommend installing the Draw-Tite Max-Frame Trailer Hitch Receiver # DT25GR because of the 2" hitch receiver, and using a 3-bike hitch rack like the RockyMounts MonoRail # RKY10004-10005 to carry your bikes....

  • How to Carry 3 Bikes on 2020 Kia Soul with One Bike Weighing 45 lbs.
    The Malone Hanger # MPG2139 does fit your 2019 Kia Soul but it cannot be used to carry any bikes over 33 lbs because that is what the individual cradles are rated for. We actually don't have any trunk mount rack that can carry a bike over 37.5 lbs. Since you have a bike that weighs 45 lbs, you will need the class III hitch # DT25GR and a hitch mounted rack like the RockyMounts MonoRail Bike Rack for 3 Bikes - 2" Hitches - Wheel Mount Item # RKY10004-10005.

  • 4-Bike Platform Bike Rack that Can Carry E-Bike and Work Behind RV
    At the rear of a trailer or RV the ride quality is very rough when compared to the ride quality at the rear of a passenger vehicle. Reason being the suspension isn't as sophisticated and there is a longer distance between the rear axle and the rear of the trailer which exaggerates the movement of the trailer when hitting bumps. Because of that only a few bike racks were designed to be reinforced enough for that type of use. So, the RockyMounts rack you referenced was not rated for the...

These crossbars have a maximum load capacity of up to 220-lbs. For a bike rack, I recommend using the Thule ProRide XT Roof Bike Rack # TH598004.

On the Transfer there is 6 inches between the hitch pin hole and the closest part of the rack.
