Heavy rides need steady support. The MonoRail Solo carries one bike up to 60 lbs, so it’s ready for most e-bikes and fat-tire builds. The platform design keeps the load balanced while the steel and aluminum frame adds strength without extra weight. At just 25 lbs, it’s easy to move and mount solo.
This rack grabs your bike by the front wheel, not the frame. The ratcheting hook on a pivoting arm clamps down over the tire to keep it rock-solid without touching paint or carbon tubes. A pivoting rear-wheel cradle adjusts automatically for different wheelbases and includes an extender strap for tires up to 5" wide.
Trail snacks, bags, or gear in the back? No need to unload. The front-mounted release lever tilts the rack away, even with the bike loaded, giving you full access. When you’re done riding, fold it upright to save space in tight parking spots. The lever locks back with a clear click so you know it’s secure.
No clanking or sway on rough roads. The threaded anti-rattle hitch pin tightens the rack inside the receiver, cutting down on movement and noise. The included adapter sleeve switches between 1-1/4" (Class II) and 2" hitches with a single screw, so setup is quick and solid.
An integrated cable lock loops through your bike frame, and a locking hitch pin keeps the rack attached. Both use the same key so there’s no fumbling with extras. Roll up, lock down, and walk away knowing everything’s secure.

I purchased this rack as it was one of the few on the market that would accomadate my 54 lb electric bike and was designed to hold a single bike. The rack was very well made with no vibration while driving my SUV. It took less than 1/2 hour to assemble the rack and hitch it to my vehicle.
I plan to use the rack to travel to other locations, with my bike, here in Southern New England. I also plan to use the rack transport my bike to Florida, where my my wife and I spend our winters.
Happy with the bike mount for my new e mountain bike, nice and stable.
Just assembled and placed on car. Easy, does everything I wanted. A bit of initial panic when I realized the instructions said to remove front fender. Not an easy or desirable thing to do on my Tern HSD cargo bike. But after some strategic thought, figured to put back of fender OVER the front wheel backstop, and bring load arm up to the fender front and all seems quite secure at this time. In fact, recommendation to tighten the hook against the fork appears to create a friction point. I expect to be very pleased with all the features as well as the weight of the rack itself, as this 72 yo granny does all the loading herself. I did not give it an excellent only because I just got it and time will tell. Happy riding.

Glad you are liking it so far, Sandra! Sorry about the initial panic though. Interesting idea about having the arm under the fender as well! ^___^ Cool bike too! I don't think I have seen one of those before. Where do you take it riding?
The MonoRail Solo is a very good piece of kit that suits my needs just fine. Mounting to the trailer hitch, and dismounting, is straightforward and only takes a couple of minutes - I'm the type of user who uses the rack only as needed, and does not leave it hanging off the back of my vehicle at all times. The tilt-down feature works smoothly and is very welcome for tailgate access. The fit and finish of the rack are good, and the price is a bit more attractive than some of the other options on the market. I'm fully satisfied with the product, and the etrailer service and shipping was excellent!

One year on and Im still satisfied with the MonoRail Solo purchase. I do wish that the shank rise was a bit lower - drivers of normal vehicles, not bloated SUVs, will find that your bikes seat and handlebars end up well above the roofline, especially for larger frame sizes. That is my sole complaint, otherwise this rack is working well and met expectations.
I probably should have done a bit more research, but unfortunately I am unable to open my rear doors with mount attached, even in the titled form. Other than that, the bike mount is nice and very well built. It’s quite heavy but not too bad. It’s easy to put your bike on it and easy to remove.
Absolutely love this product! It's going to make my trips to the North Shore of Minnesota much easier and enjoyable now that I can take any of my bikes, especially like the ease of taking the bike on and off and locking it down.
Awful. Very difficult to secure bike.
IT is a GREAT bike rack! Mine was too bulky... I wanted ONE for my Ebike when I wanted to go somewhere. It's not too heavy at all and NOT bulky like my old one.
I'm a repeat customer of RockMounts and Etrailer. You can't beat RockyMounts products and build quality and you can't beat Etrailer prices, shipping and customer service. Awesome!

My RockyMounts MonoRail Solo Bike Rack is working great. I use it fairly consistently to transport my gravel bike to different trailheads around Colorado. Thanks again RockyMounts and Etrailer.
I love this bike rack. So compact when folded up, and I can open my hatchback with ease. When extended and carrying a bike, it's solid and dependable. Highly recommended. And dealing with etrailer is always a pleasure.
Product came on the day they expected it to arrive. Was very easy to put together and install. Having the videos and information about product on there website you know what to expect and to do before it even arrives. Bicycle rack seems well built and sturdy. Thanks Etrailer. Will be ordering a trailer hitch for my car in a couple weeks.
Bought this Solo RockyMount rack for my E-bike. Not easy to find a bike rack that holds fat tires and the weight of the E-bike.
This bike rack is better than I had hoped for, very well built but light weight and my E-bike goes on it very easy.
Easy to assemble in a few steps, included all tools necessary, plus locks and keys.
Lightweight but sturdy bike rack. Installed on a 2013 Prius C and the hatchback just clears the rack when not in use (added bonus!). Low profile design but with plenty of ground clearance.
No wobble design is a plus too.
Overall very impressed with the quality and fitment. And once again very happy with etrailer’s service and quick shipping.
I bought this rack to carry a Trek Verve+2 electric bike on back of 2019 Tundra. The rack was easy to assemble, only 6 screws and fitting to hitch. Instructions very clear, overall quality excellent. It doesn’t wobble at all because it is bolted to the hitch. Note that bar that fits across front wheel needs to be past top center of wheel, preferably against fork. So, if you have a front fender, you may have a problem. My Trek has a front fender, but I was able to go under it after adjusting it higher. I am close to forks, but not up against them, and it is very secure. On theft security, the two matching locks for hitch and a separate cable work well.
Installed easily. Solidly made. Reasonable weight. Ample space between rack and hatch when not in use allows the hatch to open and close normally. Handles work properly. Easy to put the bike on and take off. Wheel tray distance from the ground is manageable, even with the higher weight of an e-bike. Tilt-away feature adds convenience. I use this rack for an e-bike with a downtube battery. By grabbing the front wheel and rear tire, the retention system does not interfere with the e-bike battery in any way (though I routinely remove it for travel) while leaving frame untouched. I only needed for one bike - the others easily go on the roof, but I like the option of adding a second carrier if and when needed.
I am very pleased with the RockyMounts bike rack. The fit and finish are excellent and the anti-rattle mount actually works, NO rattling! I previously purchased the 2” receiver hitch and wiring harness from etrailer and couldn’t be happier. Thanks for fine products.
Assembly and putting the e-bike on the hitch went as expected. The bike locks in, easy on and off. Feels stable when driving. Folds up nicely to rear of car when not in use. Fits the 50# Aventon eBike and the hitch we bought from etrailers for our 2024 Subaru Legacy.
Great rack! I bought this to take my bike across the country. Needed something that could easily allow me to ride when I wanted. It fit perfect on my Subaru Baja. The tilt function really made this rack functional while en route. I drove on some pretty gnarly roads and the rack held up great. It did get a little shaky and noisy when on loose gravel but that was to be expected. I've had the rack for about a year now and still no complaints.
When I received the rack the box was damaged and the rubber parts had some dings on them. Customer service was super helpful and made everything right.
Definitely recommend these guys over competitors.
Great product and easy to put together. I did notice that when using the 1.25” hitch, there is a little bit of play with the hitch moving north and south. Not overly concerning though as I have read that a little bit of play is normal. Additionally, riders who use a mud fender on their front fork might have a bit of trouble getting the swing arm snug as can be. I recommend removing your mud fender from the front fork before traveling for the most snug fit. 4/5 due to the little bit of play with the 1.25” hitch. All together, the rack is affordable, and works great. Would recommend to a friend.
This was my very first purchase ever of a bike rack and I have to say that not only was etrailer.com the best price I found but also the most helpful with information on the various racks available. I wanted a single bike rack for my new eBike and after looking through numerous possibilities, finally decided on the Rockymounts Monorail Solo as not only did it fit the bill for a single bike but also has the advantage of an add-on rack should I ever decide I need to haul around two bikes rather than just one.
My major priorities were a rack that would safely hold the additional weight of an eBike, be easy to mount as I'm older and have a bad back on occasion and not break the bank with cost. After watching the available online video and using the easy-to-follow enclosed instructions and tools, I was able to install the RockyMounts Monorail Solo rack quite effortlessly by myself in less than 30 minutes.
Loading and unloading my bike (which weighs about 50 pounds) is quite easy and when not in use, the rack folds up close to the back of my car. Should I need to access the back of my Tucson while the bike is loaded, it's very easy to lean the rack forward and open the hatch. Overall I am very pleased with this product and would definitely recommend it to anyone looking for a solo rack.
Feels solid, minimal wobbling. Easy to get bike on and off, and to access the trunk with the bike on. Like that it can be expanded to hold 2 bikes, and the relatively low cost. Used with a Curt hitch from this site on a 2017 Miata.

After a year of constant use, its still good, but requires occasional lubrication. Also the extension for the second bike has trouble with bolts coming loose, and requires loctite every time its installed. Finally, the wobble with 2 bikes on the 1 14 reciever is enough to make you drive a bit more carefully. If you can fit it, get the 2. For a single bike use I think this is still best bang for buck.
I just finished installing this rack on my 2017 Subaru Outback. I've been researching platform racks for about 2 months now, and the most important things to me (other than a reasonable price) were no frame contact, ease of getting the bike on and off the rack, not too heavy for me to take it off the car, and enough clearance in the back for me to close my garage door. This rack is perfect for me. And I like that it's expandable to two bikes if I want to do that down the line. It came very well packaged. I am a single gal and not handy AT ALL, but I was able to do the installation with no problem. I did put my bike on the rack and took a short test ride, it was very stable. Very solid well made product!

One year later, still loving my Rocky Mounts bike rack. Easy to get on and off when the seasons change, easy to take my bike on and off, doesnt interfere with my tailgate at all. I get lots of questions about it!
Went together easy, hold my bike firmly and the tail gate on ty CX 50 goes un up and down past it in the up and down configurations.
We had trouble with the two long bolts for the tire cups, but managed to figure out that one was longer than the other. Looked like they both could have been longer. Thanks for keeping me in the loop throughout the shipping process. I look forward to getting my new bike now!

So happy to hear you got it all sorted out :) What type of bike are you looking at getting? The weather is certainly getting nice for some rides!

great! Cant believe how much easier it is to bike with this new carrier. I just pop my bike on and go! No straps or worries about if it is secure. Thanks.

While the directions could use better illustrations (at least for this left/right front/back challenged assembler!), the rack was easy to assemble. I was expecting to struggle with setting it into the receiver and using it but it was so easy that I asked a friend if I had missed something. Overall, I am extremely pleased with the product.
Customer service was beyond excellent; it was outstanding! They patiently answered all my (many!) questions, helped me understand pros/cons of different options and in the end, decide which product would best suit my needs. ETrailer will remain "my guy" for any of my future needs for which they offer products.
Condition: Installed
