    This rack is everything that I was looking for and more in a new rack. No more lifting the bikes onto the top of the car which would be a real pain with our second vehicle. The bikes are extremely secure in the cradles which is super important having had racks that weren’t this way. I really like that I can carry a variety of bikes as well. The build on this seems to be pretty bomb proof which is nice. Working with Ali was a pleasure. Oh, and the Silver Vein finish is absolutely killer!

    • altaracks (store manager)

      Thanks you so much Dan. Awesome to hear you like the color, and the rack. Silver Vein is really nice.

    Look no further… this thing is rad! A bit spendy for sure, but it will last the rest of your pedaling life. It is super sturdy and has zero wobble around corners and over bumps. I did splurge for deluxe the tie-downs, and they definitely make it bomb proof.

  5. Nicholas (verified owner)

    Great product. Super sturdy construction. Perfect carrying system that won’t damage your bike.

    • altaracks (store manager)

      Thank you and hope you enjoy the rack for years to come

  6. Jason Sebelin (verified owner)

    After having two bikes damaged with a different rack, I decided to bite the bullet and get this one. This rack is amazing! My bikes have had zero movement, and you can see them in the rear view. Again, no movement to contact!!! Grabs attention where ever we go. I wish I would have learned about this one several years ago before I purchased that other brand. Couldn’t be happier! Thanks guys!!

  7. Jeb Rucks (verified owner)

    Excellent rack and excellent buying expierence.

    • altaracks (store manager)

      Thank you for your comment Jeb.

  8. Robert (verified owner)

    After owning 5 different top rated racks, the best lasting 5 years before problems, I tried Alta, best rack yet. There is a very short learning curve for lifting your bike up and slotting into wheel cradle which is angled and requires control of front wheel while lifting. The 4 bike rack does not stick out farther than the side of my Jeep thus avoiding wheel spray from hitting bikes. No scraping slush and ice off wheels at trailhead.
    Bikes stay much cleaner than horizontal hitch rack. Construction and design are for a lifetime. Assembly very easy and NO PLASTIC to break. Thanks Alta, finally a long lasting, easy to use, bike rack for everyday use, that protects the bike, and won’t fall apart or break. Well done.

    • altaracks (store manager)

      Thanks Robert, So stoked to hear you are loving the rack.

  9. Brett C. (verified owner)

    Excellent rack. Very sturdy and rides well. It was everything we hoped it would be and more. Would definitely buy from Alta racks again.

    • altaracks (store manager)

      Thank you Brett, We are so glad our product meets your expectation.

  10. Kimberly (verified owner)

    The ease of loading and unloading, along with the versatility is what sold me on this rack. While I haven’t had it completely full yet, this rack is built solid and we have not experienced the swaying and movement like we have in other racks. Ali was easy to work with and always quick to answer a question or provide more information.

    • altaracks (store manager)

      Thank you Kimberly, Just treating other the way we would like to be treated. So glad the rack is meeting your expectation, hope to serve you for years to come.

  11. Anonymous (verified owner)

    This thing is a beast. It is built like a tank. I think the only thing I would request is that the hitch stabilizer be powder coated like the rest of it. Currently it is just bare metal. Bikes fit great and I can drop my tailgate without touching the bike rack which is a huge plus.

    • altaracks (store manager)

      Thanks for the comment, the stabilizer is zinc plated and wont rust. Happy shredding.

  12. Kenny Grant (verified owner)

    Awesome bike rack, I did months of research and after looking g at all the other vertical bike racks I’m super stoked on my Alta Rack. Great customer service, Ali is a great hard working dude and it shows in work.

    • altaracks (store manager)

      Thanks Kenny,
      Super stoked on your positive experience. Shred on.

  13. Shawn D. (verified owner)

    The rack is well built and engineered. It was easy to put together! The installation videos from the Alta site where a great help. The rack is easy to load with multiple bikes.

  14. Ben Peteocco (verified owner)

    Haven’t got a chance to test the rack out much yet but seems to be excellent quality and was fairly easy to assemble. Only complaint I have is looks like I will have to purchase some kind of hitch extension to get my F150 tailgate to drop completely with rack on.

    • altaracks (store manager)

      Hi Ben,
      Thanks for your review. Yes, the current setup has interference with the big flairs the Ford trucks have on the top of tailgate. ALTA Extender will allow for full clearance without having to lower the rack. We also have a extended hitch piece in the works that can be swapped out to give you that tailgate clearance.

    Worth more than the 3 racks you would buy and need to replace over the years instead of getting this awesome rack. Enough clearance to open the rear gate on 2011 Honda Pilot.

    • altaracks (store manager)

      Thanks Byron, thats what we say as well. The only rack that grows with you

  18. Darrin Davis (verified owner)

    This rack is the real deal. Notice the attention paid to hardware/bolt hardness, the multiple engineered solutions for the dynamic forces affecting the rack. Performance, looks, and easy reconfiguration. Check that silver vein box if you want to flex out dragon scale style.

    • altaracks (store manager)

      Dragon scale is the real deal

    The quality on this rack is superb! Excellent attention to details. So happy with this. The online videos were very helpful for the install. Ordering was a effortless. Love the ability to customize for each bike. Thanks!

    • altaracks (store manager)

      Hi Shane,
      Thanks for noticing the details.

  20. Chad Wilson (verified owner)

    Very impressive build! I had a little trouble assembling the pinch bolts correctly so the pivot lever part fit snuggly but otherwise everything is great!

  21. Steve D. (verified owner)

    After a lot of research and checking the web for real world reviews and use videos we figured the Alta rack would be the best fit for us.
    It arrived promptly. Was easily assembled and is quite simply ROCK SOLID on the back of either of our vehicles.
    We were looking for a bike rack that could do it all. Fit all our vehicles and be durable and solid and this is it. It’s simply a great bonus that I can have this on any of our vehicles and still have full access to the bed of the truck without having to remove the rack or unload it. We can even fully open the liftgate of our Expedition Max by simply tilting the rack.
    And we’re looking forward to being able to use this rack on the back of our Jayco travel trailer to haul all our bikes on our camping trips. Hanging off the frame of a travel trailer is a very bumpy place to be and the off road testing done with this rack was one of the greatest selling points in putting our minds to rest about having a rack that didn’t shake itself to pieces.

    Bravo to those at Alta. This is a great product so far and we hope to have it in service for years to come.

    The ONLY thing I can think to make this perfect is a way to easily stow the top rubber straps when there are no bikes on the rack. You can thread the bottom ones through the extra slots but the tops ones have to be coiled and secured with a small bungee. And if this is the worst criticism we can level on the product we’ll be beyond happy with this rack.

    Looking forward to many, happy, safe, family miles with this rack! Thank you Alta Racks!

    • altaracks (store manager)

      Hi Steve,
      I am really trying to understand the last part of the comment. Not sure what you mean about coiled and the use of bungee. The top straps weave thru the slot on the basket as shown on the assembly video. no need to bungee or secure them, thanks for the review though. Please contact us we would love to make sure the rack is 100 percent to your expectation.

    Best rack ever! Cradles the bikes like a baby, like how the bikes don’t touch each other and they are also secure when traveling down the road on the back of our fifth wheel! Good job Ali!

  26. Mark (verified owner)

    Fantastic, rock solid rack! Ali’s instructional videos made assembly super easy. Great customer service!

  27. Anonymous (verified owner)

    The customer service is great and the product is well made. The bikes in our 25 ft RV did not move w the brakes strapped and choke in place. Only issue was drag. Wish the anti rattle/stabilizer was reversed so it wasn’t the lowest point.

    • altaracks (store manager)

      Thanks for your reply, Since the external stabilizer pulls down on the rack. the only way to make that happen is to have it setup as it is right now.

  28. Anonymous (verified owner)

    So far I am very impressed! We took this on one trip and it was bomber. The rack is awfully big, but it was very satisfying to know that there was no way the rack or my bikes were going anywhere. Looking forward to loading it up when we head out for the west coast in a few weeks.

    • altaracks (store manager)

      Hi Neal,
      Thanks for your review. Big rack for a lot of bikes. Yet still the lightest on the market. Happy travels.

  30. brian smith (verified owner)

    Rack is awesome and easy to load and unload . Little disappointed that even with the extender I can not fully open both doors on my 2019 Ford transit . Bottom rail also came with one end bent . Other than these issues I am fairly happy with my rack . I think if I knew I couldn’t fully access my cargo area with the rack on I might of looked for another option .

    • altaracks (store manager)

      Totally bummed about this, gladly will send a new low bar damaged during shipping, please reach out to us thru email.

    • altaracks (store manager)

      Thanks Randy, Noticed the straps are narrow, we recommend wide and low for RV strapping.

  33. Alex Trueman (verified owner)

    Outstanding quality. I didn’t realize that RV-rated was a thing. I have broken a couple of racks on the back of my RV. This one stood up to the San Diego Denver return trip at highway speed. Hoping for many more thousands of miles.

    Perfection!! For one, great people and product. Made in the USA. Well thought out and very light, great design. Bought a 4 Pack to replace a Thule XT Pro 4 Bike. Wanted to improve my departure angle on my 4Runner for Offroad use and Stability. This does the trick completely!! Using the retractible straps, it is solid as a rock. Thank you guys for answering questions and getting this to me so quick. Cannot say enough about this incredible rack.

  35. Jason Gurba (verified owner)

    This is by far the best rack out there and I am so happy I did the research and pulled the trigger on this rack. I couldn’t be happier. I recommend this rack now to anyone I know who is thinking about buying one and tell them I would not even shop around for others. I previously owned a rack made by one of the more common brands and needed something that worked better and would fit different size bikes to accommodate our family. This is the rack! Additionally the price is comparable or even less than any of the next lesser capable options (at least here in Canada). The customer service was amazing when I asked for a small adjustment in my order and it arrived here in Canada 6 days after my order! That is amazing but even more so during a pandemic! I can’t say enough great things about this rack and the service! Also knowing that Ali is constantly working to make improvements and they would be backwards compatible gives me more comfort that I invested in the right product!

    After losing a rack and 4 bikes years ago due to a sub-par rack, I was excited to find an extremely well built rack that can house the now 6 bikes we have. It fits so good on the back of our motor-home which no rack out there does…..and fits 6 bikes. Love it, thank you!

  37. Christopher Olivas (verified owner)

    Awesome multi functional bike rack , great customer service.

  38. Jeffrey J Bellinger (verified owner)

    The Alta 4 pack is by far the best bicycle rack I have ever purchased. The materials used in building this rack are well thought out and very high quality and the welds are impeccable. I also purchased the lefty conversion kit for the back of my Truck camper the whole rack is very well made and you can tell that Alta racks takes extreme pride in the product they sell. The customer service is also top notch. I would recommend this rack to anyone looking for a American made bike rack. Keep up the awesome work Alta Racks.

  48. JEFFREY CAVICCHI (verified owner)

    The rack’s bomber quality was mirrored in the way it was packed and shipped. It arrived in pristine shape in heavy-duty boxes made specially for the rack.

    Assembly went smoothly, aided by the excellent instructional videos, and fit and function of the rack are outstanding.

    Customer service was outstanding as well. I asked for instructions on how to use the weight-relieving strap I ordered to accommodate an e-mountain bike, and rather than simply emailing me Alta put together a video the next day demonstrating exactly how to use the strap.

    Top-notch all the way around!

  49. Mark Miles (verified owner)

    We love this rack. We have a steep driveway which means most racks bottom out at the transition to the road, even with a normal 2 bike platform rack. Forget about hauling 4 bikes. I Have not been able to find anything that would work, even other vertical racks, until I found Alta Racks. The build quality is exceptional and the design is well thought out. Customer service is great and my orders have been processed and shipped very quickly.

    I haven’t had a chance to use it yet, but the install was great and it seems solid.

    This is an excellent bike rack. Much easier to load than horizontal racks. It is very sturdy. The assembly took about 1.5 hours. Mine arrived with a defective screw hole where the bolt goes through the hitch receiver and into the rack hitch. I contacted the company by email and received a reply 11 minutes later with troubleshooting info. When that didn’t work, they quickly shipped me the replacement part and now it works perfectly.

  59. Doug Vogt

    Great quality, easy to assemble, easy to use.

    Very sturdy rack. The online YouTube videos showing how to put the rack together were great. I’m very happy with my Alta Rack!

  63. Kendel J. (verified owner)

    This rack is a beast and will probably outlast me. Super solid and holds the bikes securely. I have owned Kuat and Thule racks in the past and the Alta is superior in every way. The only thing I don’t like about the rack is that it requires a rachet and socket to remove and install the rack. If you leave the rack on full time it’s no big deal, but taking it on and off is a little labor intensive. Overall, a small price to pay for such a beast of a rack.

  64. Brandon (verified owner)

    I researched all the racks of this style. What I liked about Alta is that it is more of a “system” that will expand as our needs grow in terms of bikes, winter sports gear and other accessories.

    The rack was easy to put together and works exactly as needed for transporting multiple bikes.
