Overall the rack is solid AF, fits my FJ cruise as expected and can still open rear with bike off. The reason for deducting 1 star is the tray could be deeper allowing the arms to effectively engage higher and the higher channel walls help stabilize fron wheel better. For 29x2.6" mtb tires and especially my 29x2.8" mtb will want to strap front wheel to downtube for added stability.

After a year of use, I would raise my initial rating to 5 stars. The stability of the bike has been solid even on forest roads, real 4x4 may want to add a strap. Now using this on a 2025 GMC Sierra 1500, handlebar just clears window with a softtopper. With a hard cap would likely need a 6 hitch extender.



by:

This rack is very good. But I knew that already. The reason for docking a star is that the hitch lock and cable lock on the rack are keyed differently. With identical-looking keys. This is just unnecessary confusion and yet another key to keep track of. There is no reason I can think of that these couldn't be matched. Ordered this from etrailer largely because it was in stock and shipping was free. Price on these items are obviously closely controlled by the manufacturer, so no price break here, same as everywhere else. Shipping was quick and I was kept well-informed.

A year in, still love the rack. Still wish it used a single key. Sometimes, after drives on unpaved roads, the piston shaft gets “gritty” and doesn’t operate as smoothly - but a good hosing-off when you get home fixes that. Its functionality, stiffness and hands-free deployment keep it the best in class for a single-bike rack.

@Scott Love to hear you're still lovin your Kuat rack! There is a way to key everything to the same key code. Kuat does sell packs of key and lock cores on their site and you can pick what key code you want. We don't carry it so you would need to go to Kuat's site for that. I know its not ideal since it's something extra you have to get, but is an option if you want everything Kuat to be keyed the same.


by:

Excellent bike rack. Bike is very secure and stable even on bumpy roads. I never worry about it coming loose. And the ramp makes it do easy to load a heavy e-bike. Highly recommend them both.



by:

Easy to use! Bicycle is solid, does not swing. Easy to mount and remove bicycle.



by:

Great rack, eTrailer has always been a good company to deal with. Purchased several accessories and racks, always fast shipping and great customer service.



by:

The rack is excellent and very sturdy. Easy to assemble. Well made. I gave it a four star rating because, for some odd reason, Kuat does not include a 7 mm hex key which is necessary in order to remove the bump stop so as to install an e-bike ramp.



by:

Trying to find a single carrier for a 65 pound bike took a while, it I couldn't find anything even near this rack.



by:

Awesome engineering on this product. Great low profile rack.

Great service

Excellent rack. Quality build, great design, easy to use. No hindrance to back up camera view. Works with my fender. Will take a ramp for heavy e-bikes. The best part was etrailer's delivery. I needed the rack by July 3rd for a July 4th ride and Kuat was out of stock. But etrailer came through by delivering the rack in 3 days. Thank you etrailer!



by:

Fast delivery and good service



by:

So far I love it , I’ve not had a chance too put it together yet as I am waiting on my receiver hitch to be put on



by:

Absolutely the best for what I needed, even for a heavier E-Bike like mine.

  • Recommended Single-Bike Rack With A 2" Shank For A 55lb E-Bike
    Hi Tom, For a single-bike rack with a true 2" shank I recommend the Kuat Piston SR Bike Rack for 1 Bike # KU88ZR. This bike rack is rated for use on all vehicles, 5th wheels, motorhomes, travel trailers, and flat towed vehicles so you'll be able to transfer it over to whatever you want. When on a vehicle it has a 100lb capacity and when on an RV the weight capacity will dip down to 67lbs to accommodate for the harsher ride quality an RV would place on the rack. The shank base of this...

  • Do You Have a Bike Rack for a 100 lbs E-Bike?
    Hey Lowell. We have one bike rack that has a 100 lbs capacity. It is the Kuat Piston SR Bike Rack for 1 Bike item # KU88ZR. This bike fits a 2" class III hitch. It fits tires up to 5" wide and wheelbases as long as 53". The rack itself measures 59-1/2" long x 4-15/16" wide x 3-7/8" tall and weighs 42 lbs. What kind of bike do you have? You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

  • Will Kuat Piston SR Bike Rack Work with 5" Wide Tires?
    Hey Kim, thanks for reaching out! The Kuat Piston SR Bike Rack # KU88ZR just sits straight out so while it doesn't sit lower, it definitely doesn't rise up so I can see why you have the concern about ground clearance on a 2024 Honda Odyssey. It will work 5" wide tires though so you're definitely good on that front. Back to the height concern. There are some alternative options to get you better height so if you're afraid of ground contact then I recommend checking out the Kuat Pivot 2...

  • Kuat Single Bike Rack that Can Fit Fat Tires for GMC Sierra 2500
    Hey Jerry, Kuat does make a single bike rack that can work with fat tires up to 5 inches in width with the Kuat Piston SR Bike Rack for 1 Bike # KU88ZR. This is by far the nicest bike rack on the market too so you'll really like this rack. It would also work great in the hitch of your GMC Sierra 2500.

  • Would A Hitch Extender Be Needed For A Kuat Piston SR On A 2024 Ford Bronco Sasquatch Edition
    Hey Joe, I spoke with Kuat since I didn't have a Kuat Piston SR Bike Rack # KU88ZR on hand to measure and they stated that from the center of the hitch pin hole in the shank to the start of the wheel tray is 9-1/2". You would likely need a hitch extender like the # HL20B in order to clear the spare tire on the back of your Bronco. The # HL20B can add on an additional 7" or 10" of clearance but will reduce the capacity of your trailer hitch by 50%. The 50% reduction likely won't be that...

  • How Does Hollywood Racks Crosstrack Compare To Kuat Piston SR Bike Rack?
    Great question, Hannah. Both use wheel-mount systems and avoid frame contact, but the Crosstrack 1 bike 2" hitch # HLY98RR has a tilt feature and no-tool install thanks to the No-Wobble feature (uses a handle that you twist by hand). The Kuat # KU88ZR requires use of an allen key every time you want to install or remove the bike rack, and does not tilt at all. The Kuat Piston SR does have a higher weight rating, but the Crosstrack still beats it in terms of price, and ease of use. What...

  • Availability of Single Kuat Bike Racks
    Kuat has a couple single bike racks like the Kuat Transfer part # KU64FR or the super nice Piston Pro # KU88ZR but they do not offer a version of the NV # BA22B for a single bike. I would need to know what your vehicle is to determine if we have a hitch for it.

  • Is There a 1-Bike Add-On For Kuat Piston SR Bike Rack
    Hey Marilyn, There is not a 1-bike add-on for the Kuat Piston SR Bike Rack # KU88ZR, but there is a similar option that does have one, the Saris MHS DUO Bike Rack for 1 Bike # SAR23MR. Like the Piston SR, the MHS Duo is a wheel-mount rack and with an 80 lb capacity is made for heavy bikes. Then for the 1-bike add-on you can use the DUO 1-Bike Add-On for Saris MHS Bike Rack # SAR78MR. One thing to note is that the 1-bike add-on has a 60 lb capacity.

  • Best High Quality Bike Rack For Fat Tire Cruiser EBike Arctodus TI
    Wow what a nice bike! I had to look it up. And you are right to ask. The Crosstrack 1 Bike 2" # HLY98RR or 1-1/4"/2" option # HLY68RR officially support up to 4” tire width and a 52” wheelbase. If your tires exceed 4", it may not seat properly in the trays and the wheel hook might not lock down securely. Some users report being able to use it, but by spec you’d need a rack designed for fat-tire bikes. I recommend instead using something like the Kuat Piston SR Bike Rack for 1 Bike - 2"...
