Safe stuff.

If pressed, we'd have to admit that mounting our bikes onto a hitch rack like RockyMounts SplitRail 2-Bike Hitch Rack gives us a sense of security few other racks can match. Our feathery carbon race builds are pretty easy to lock down on just about anything, but our burly enduro beasts carry a little more weight around their midsections, and we want to know they're mounted on something that can handle the heft.

RockyMounts equipped the SplitRail to accommodate everything from your son's cruiser to your aero tri bike, with each strut including four inches of side-to-side adjustment to ensure you get a secure fit on different frame sizes. The SplitRail isn't picky; it works with any bike with wheels between 20 and 29 inches, and was built with space for plus-sized tires.

Out of the box, the SplitRail comes ready to be installed tool-free, so you won't waste precious ride time struggling to decipher a complex installation process. RockyMounts' proprietary anti-wobble technology and the included locking cable further boost our confidence. When you aren't using the rack, it tucks away flush with your vehicle in stow position, and it comes with Tilt and Use settings to allow you access to the back of your vehicle while you have it mounted.

  • A durable aluminum and chromoly steel hitch bike rack
  • 2in size weighs just 44lbs fully assembled
  • Tool-free installation gets you on the road quickly
  • Accommodates up to 48in wheelbase and plus-size tires
  • Includes locking hitch pin to secure rack to vehicle
  • Stow, Use, and Tilt positions adapt the rack to the moment's needs

Will this rack work with a 27.5 x 3" tire and 46.25" wheelbase bike? On other bike racks my bike is very unstable and the front wheel sometimes rotates off the rack.

Hi David, per RockyMounts site this rack will fit a 3" tire and up to a 48" wheelbase.

How fast is it to take this rack off and put it back on the car?


Great question. This mount will have a lock that uncovers a pin. It's a two step process putting it on and taking it off, however it's simple and depending on your familiarity, shouldn't take more than a minute or two.

Let me know if you have any other questions.

Awesome Rack.

  • Familiarity: I've put it through the wringer

Awesome rack and local CO company. Anti-wobble wedge worked pretty well the first time, but after talking with their support and trying again - I got it perfect. There is zero movement and the rack feels rock solid. I've talked to RockyMount's support a few times and they have been fantastic.

Awesome rack so far

  • Familiarity: I've used it several times

Got this thing a few weeks ago and have had very little issues with it. The one thing I noticed was the wedge mechanism that allows for a snug fit was a bit to large to fit into my hitch receiver. I had to grind down the wedge in order to get it to fit in the small amount of space around the hitch. You can find clamping hitch bolts that would eliminate the wedge all together and I think when reinstall the rack in the spring that will be the way to go. Once the rack is on it is sturdy and a very well functioning hitch rack. Aside from the installation being a bit tricky I am loving this rack!

Splitrail Review

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

Comp Cylist's sale prompted me to buy this over the other brands, Thule, One Up, etc. I ordered on 8/20 in the evening and received on 8/23. Free shipping and 0 tax, awesome service from CC. The splitrail is easy to put together, just had an issue with the anti-wobble. Instead of using a hammer to wedge the bracket, which did work, but I did not have the bracket tight enough, so it moved. I took the rack off, moved the bracket a 1/4 inch, tightened it down, and the wedge system works great. It is not as easy as my friend's Kuat ball extender, but once you figure it out, it is easy. Also, I like the fact that once set up, no tools are required to put the rack on an off. I was deciding between this type of tray rack and the 1up (which is awesome, two friends with it), but for some reason I always have difficulty with the release handles to get the bikes off, so I went for this rack. The handles to the arms have been changed to the ones with the blue trigger ( Rocky confirmed this via email). I was using an old Sportack that lasted 11 years, and secured the bikes by the frame. I have no doubt this rack will last. The cable locks are fine for what they are, no matter what brand of rack you buy, extra security will be needed if you leave the bikes unattended and out of sight. The hitch pin lock and wall mounts are easy to use. I do not leave racks on my vehicle due to having the rear tire, this rack as others will not fold up with the rear Jeep tire. Rocky does sell a hitch extender that will work with the rack, which I will buy once they have in stock. That way I can have the lock keyed with the other locks on this rack. In the picture, I have a large Primer and my friend has an XL Mayhem (which is slightly over the 48"-bike fits fine). Great rack and looks good too.,

Rocky mounts

    This rack is solidly built, good to look at, holds bike secure, and has all the features you really need in a rack like this. Why 4 stars instead of 5? The wedge system designed to stop rack movement does not work real well. I've tinkered and tinkered, but to no avail. There's not a lot of movement, but it is not steadfast either. All in all I recommend the rack, but I have seen systems that prevent movement better than this one.

    I received a bad unit, but...

    I had the rockymounts split rail 2 bike rack with a single add-on for a total of 3 bikes. I love the concept of this design, but it needs modifications. I would NOT recommend this hitch rack due to safety concerns. With a little redesign, this could be a great rack.

    It was installed on my 2015 CRV with a Draw-Tite class III hitch receiver. The bikes we carry are: Men’s Commencal mountain bike (size medium, 30 lbs), Women’s Specialized Jynx Elite mountain bike (size small, 25 pounds), and a Boy’s Trek bike (24” kids, 20 pounds).

    Bikes are very easy to put on and take off.
    Bikes are very secure on the rack.
    Integrated lock.
    Easy to fold up and down by myself.
    Nice look on the car (not an eyesore).

    The wedge did not fit into my hitch receiver and so there was more rattle/movement than there should have been.
    I had to continually tighten the knob to keep it secure.
    THE WELD BROKE (connecting the platform to the tube that goes into the hitch) and the bikes fell off while I was driving. See photos (first 2 are the pics while broken). Thankfully it happen when I was driving slow in a smooth flat parking lot with nobody behind me. If this had happened on a road or the highway, my bikes would have been destroyed and I would have caused major accidents behind me (with serious injury/death to others). Me and my kids were left stranded 3 hours from home (our first trip away from home with the rack!). The only way to get home with our bikes was to go to a local bike shop and buy a Thule rack at a much higher cost and have the guys there help me get it put together and on my car.

    Rockymounts needs to get rid of the weld and instead use bolts to connect them like other reputable manufacturers. My new Thule rack is connected with bolts and feels much more secure.

    Edit: Rockymounts saw my review and reached out to me. They were wonderful. Their engineers were immediately brought in on the issue. They were able to tell me that 5 units were manufactured with a flaw that could cause the weld to fail. They caught it after the 5 units, fixed it, and have been working to track down the units. Unfortunately for me, mine failed before they were able to get the unit back. They are a top notch company to work with.

    I received a bad unit, but...

    Mount Up!

    • Familiarity: I've used it several times

    RockyMounts brings a solid contender to the hitch mounted rack field. I've previously owned the Yakima HoldUp, and have used a buddy's Kuat NV quite a bit. The Splitrail is on par with both of those. Though having a claimed weight of 44lbs for the 2in receiver option, the rack feels lighter, and more balanced than the HoldUp which claims to be 39lbs.

    It took me 30 minutes to install the Splitrail, and assembly is very straightforward and easy with the included hex wrenches. The hitch's fir system creates a very stable interface, with no wobble, but can be in issue if you're moving the rack from one car to another regularly. The rear handle for adjusting the position of the rack is also a strong point. The rack has ample clearance for 29 and 27+ tires. Though RockyMounts doesn't recommend it, I was bale to fit my fatbike with 4.8 tires onto the rack with a ski strap, but do so at my own peril.

    The locking system is a weak point in my opinion compared to other offering. A cable extends from the arms, and a metal chuck locks into the end of the cable creating a loop. No rack's included lock/cable is very substantial, they're all there to keep people honest, but the Splitrail's system limits where you can loop the cable. If I were leaving bikes on the rack during an extended period of time, I'd use a thicker cable looped through the hitch like I have with my HoldUp.

    Overall the Splitrail is a great rack, that's easy to use, and will get you and your bike to and from the trail with ease.

    Mount Up!

    Surprised RM did not make the wheel wells at least 4' compatible from the start or offer an add on product. I use a BrassKnuckle roof rack with the fatty attachment and the extender straps seem like they would fit well on this rack.

    A new challenger

      I've run the gamut of rack ownership over the last 10 years, I had a Thule T2, then upgraded (in my opinion) to a Yakima HoldUp. I moved the HoldUp over to my girlfriends car and have installed the SplitRail on my Tacoma about a month ago.

      Like Sean's reviews below, all around an easy install, with them including all the necessary tools. Bikes are held securely, and you can offset the trays if you have clearance issues with bars/etc. I echo his sentiments on functionality of the rack, but will add my pro's and con's below.

      Ability to add on one or two additional single trays on the 2in model allows you to customize your hauling as needed.
      The biggest pro over the Thule and Yakima I have owned and Kuat's I have used is the lever to lower the rack. Its conveniently placed, and one handed in use. By far the best out there, hands down.

      Most stable and solid rack I've owned.

      One small, nitpicky con is the lack of ratchet on the rear wheel strap, but it's really not necessary, and functions very well without it

      Lock system is a bit less streamlined like the thule/yakima post and hole lock setup, but the loop can be adjusted if needed.

      I think the biggest downside, which a lot of folks will not need to worry about, is the trailer hitch install/fitment is more complicated. This results in a fantastic hold and is the most stable rack I've used (I'll say it as may times as needed!). However, if you need to move it between two vehicles, you will need to set up the hitch attachment again since some hitches have the pin hole in different locations.

      In summary, this rack gets my vote and will stay on my truck, while my girlfriend will use the HoldUp. A great rack, I'm excited to see its long term durability.

      Solid and Sophisiticated

      • Familiarity: I've put it through the wringer

      A durable and functional hitch rack is an essential component for transporting your several thousand-dollar investments safely from place to place. There are many rack makers out there, but I have always admired Rocky Mounts styling and specifications. When word got out that the Split Rail was coming to market, I got really excited and picked one up. I can tell you straight up that this is the best rack I have ever owned and I was impressed by its ease of installation, build quality, and overall features.

      -Installation: Right out of the box the rack needs to be assembled. Fortunately the folks at Rocky Mounts include great instructions and the tools to put it together. I had the rack unpacked and ride-ready in under 30 minutes!

      - Build: This rack is stout. It's split rail design seems bombproof and the injection molded plastic is well made. The rack feels very solid and the anti-wobble wedge makes the rack very stable over rough roads and speed bumps.

      -Features: Well thought out tray design that accommodates virtually any wheel size from 20" to 29" Plus. Integrated locks keep the bikes where I left them, and the ratchet closure system is typical of what is offered today. One feature I do appreciate is the small hook that holds the ratchet open when you are loading/unloading.

      -Functions: As a two bike rack this is a perfect set up. The actuating lever is intuitively placed at the far end and it can easily be pulled to lift and stow, drop to load, or lean to access your back hatch (very important).

      Overall, I would recommend this bike rack from Rocky Mounts to anyone who rides mountain or road and needs a solid system to protect and transports their beloved machines. Hit me up with any questions and I will be happy to provide additional specs.

      Will this rack accommodate fat-tire bikes? Thanks.
