I think a longer strap instead an extender would have worked just as well and would be cheaper to produce.

It has been a great product to use! Super simple and easy load and offload. The built-in cable lock is a plus. No problems whatsoever.

by: JM 08/24/2017

Product was easy to assemble and took less than 20 minutes to put together. Package came in great shape and in a timely manner for the shipping price I paid. Super happy with the rack itself and the quality of craftsmanship it has. Definitely would recommend this rack for anyone else in the market, you won't be disappointed. Product does come with one phat bike adapter as well.

Put the Kuat NV 2.0 on our SUV and loaded a phat tire tire to go to the beach only to realize the strap that came on the NV 2.0 wasn’t long enough. We took the bike and the rack off. We immediately got one etrailer to order the right straps. Love etrailer... best customer service!! Can’t wait to install the new straps.

After a year, these are still great on the Kuat. I had actually forgotten these came with our rack when we purchased it new, but it’s great that we have a couple of spares. This means, we will have them forever. We do store our rack in an enclosed covered area when we don’t use it.

Ratchet system works effectively. Minimize worry
and secure your bikes properly to your rack.

Velco strap is very functional. Will work well
on any location where additional Tie-Down further
secures your bike to the rack.

After a year of use and thousands of miles travelled, these straps have kept my bikes secured to the NV2 Rack. Your expensive rack is useless without these.

Great adapter for carrying fat bike bikes. Easy install.

Just what you need for a fat tire bike and the new MTB wide tires. This is a very good quality adapter for your kuat rack.

It works out great. I have been using it on my specialized E bike which has really wide tires. It really makes it easy to attach my bike to the rack.

by: DJW 08/10/2021 One Year Later

The Kuat single bike carrier and the adapter were not compatible with my Sondors XS Ebike. Regardless, Kuat's design was generally poor with ill-conceived components that must be assembled (an awkward process) and fasteners / tab-in-slot elements that were complicated as well as weak. My bike could be pushed more than 12 inches, forward or backward, using only the tip of my little finger. The bike carrier and the fat tire adapter (basically just a strap) should be redesigned and sold at 1/2 the price.

by: Ivan 09/29/2021 One Year Later

Great product. Secures the bike easily and gives me piece of mind that it won't fall off.
I did have an issue getting the brace over the fat tire but etrailer support were very helpful and explained the bike needs to be tilted over to get the brace up to the right place. I also bought my Kuat Base form etrailer and it's really really good, supper sturdy, no rattle and no more frame damage, well worth the money.

by: Renee 04/16/2023 One Year Later

This bike rack has performed great. We are hauling 2 heavy fat tire e-bikes. Loading and unloading is a snap. I had to purchase a 2” drop extender to be able to lower my tailgate. Tilting the bike rack allows for easy access to my truck bed. Great product!

by: Barb 02/20/2022 One Year Later

This adapter is just what I needed to secure my fat tire bike to a Kuat rack. Simple to attach to the strap that came on the rack, gives me plenty of length to wrap around the tires and secures and holds tightly. And, as always, excellent service from etrailer.com!

excellent product, could not be happier!

by: James G 04/06/2020

Quality and kept promises. Thanks etrailer!! Our Kuat 2 bike rack and extension straps for our fat tire bikes arrived on time and as promised. A boxed end wrench and hex head tools are included. Assembly went ok but could have been a little easier (for this SAE, not mm, guy) if the instructions had the actual screw sizes depicted in scale. Process of elimination and they all got used in the correct locations. And a second pair of hands was helpful in keeping the frame in place while I installed the front wheel ratchet arm assembly onto its pivot mount. All parts fit together correctly and tightly, indicating to me that the design and quality of the product wasn't shoddy or forgotten. The included 2" adapter on the hitch mount went into the receiver on my truck and with the included mounting screw and wrench, it tightened nicely. Only one person was needed to lift the complete rack and start and tighten the hitch pin in. The frames horseshoe design allows you room to walk the lifted bike onto the tire cradles without banging your shins. Without any effort you can then balance the bike while you swing the ratchet arm over and onto the front tire, wiggle the tires into their cradles, attach the safety straps, and your ready to go. It seemed very stable while traveling only 16 smooth road miles on its first journey. Comes off easily and hangs on the garage wall waiting for next weekend and a planned 185 mile one way road trip.

I have bought items from etrailer three times now. Their service is excellent, and the products arrive very quickly. This time I bought the Kuat Phat Strap. It slides over the strap that is already attached to the bike rack to extend the strap. It works well. My wife’s bike has five inch wide tires, and the strap is more than long enough to reach around it.

by: Christopher 04/06/2022 One Year Later

After a year of using these straps, product is still performing as they did when new. Straps hold the bikes tight, no issues with performance or quality and price was very affordable. If you have a fattie with small tire widths, the bike may fit without these straps, but having these gives peace of mind when traveling over long distances and/or uneven surfaces.

Perfect. Holds my 5 inch fat tire on the Kuat Transport without any hiccups. Thanks!

by: Joshua 05/31/2019

Works as expected. This is just a longer version of the straps that the bike rack came with and it enables my Kuat Transfer 2 bike rack to accommodate my 26x4" fat bike tires.

by: Stephanie 02/09/2019 One Year Later

Excellent straps for my fat tire bikes. Gives plenty of room for all sizes of fat tires. Locks down nicely.

by: Jorge 01/11/2018

The velcro strap for the front tire is strong and long enough to go around a 4.8 tires with plenty of space. But the other plastic strap extender doesnt look promising, it does what its suppose to do. Extend the strap to hold a fat tire. Küat should have just sent a longer version of the original strap for cleaner and less cumbersome task of adding and removing straps.

by: Russell 09/12/2025

I had no idea this could be so simple and easy to use! Well done!

by: Philip H 09/23/2020 One Year Later

It does the job that I bought it for. It securely holds a fat tire mountain bike on to my new KUAT sherper rack.

by: Keith J 07/22/2016

An absolute must if you are going to mount a fat tire bike on a Kuat NV2 rack. The straps on the rack do not reach and attach on a fat tire bike. The Velcro strap is a nice insurance piece for the front tire, but not necessary.

by: Solvejg 01/29/2023

It came fast, however the shipping costs were higher than the purchase costs. I will therefore probably not purchase from this site again. The item was in good condition and easy to use.

by: Christopher 03/02/2021 One Year Later

It works for my Rocky Mountain Blizzard with 4.8" wide tires, so it'll probably work for you too. Simple solution to a big, phat problem.

Can Kuat Sherpa 2.0 Bike Rack Carry Two Fat Bikes that Weigh Less than 40 lbs
The Kuat Sherpa part # SH22P bike rack can carry fat bike tires up to 3 inches in width. The rack has a 40 lb per bike capacity so as long as yours weigh 40 or less like you mentioned you'd be good.

You are actually covered by the Federal Magnuson-Moss Warranty Act which states that if something breaks on your vehicle and you take it in for warranty repair, the dealer must honor your warranty unless whatever modifications you have added to your vehicle actually caused the problem in question. This means that unless the Curt Trailer Hitch # C11435 that you referenced is the reason that you are needing repairs on your 2019 Mazda MX-5 Miata the dealer has to honor the warranty. If you...

Fat Tire Bike Not Fitting Kuat Transfer V2
Hi Eddy; it sounds like your fat tire bike might exceed the capabilities of your Kuat Transfer V2 #KU74FR. We do have the Phat Bike Adapter Kit for Kuat Bike Racks # APBK but that is just the straps. These would not solve the problem you're having with the arm and the cradle. I will say if the fat tire isn't sitting down inside the cradle but more on top that is normal. This bike rack is designed to hold bikes with an 18" - 29" wheel diameter and up to a 50" wheelbase. I would double check...

Can Rear Bumper Cover be Reinstalled With Draw-Tite Trailer Hitch Installed on a 2019 Dodge Durango

Looking For Fat Bike Tire Strap For Kuat NV 2.0
Hello Chris, thanks for reaching out. Kuat does make a fat bike strap that works with the NV 2.0, part # APBK. This allows the rack to accommodate tires up to 5" wide. There is not a strap that can be added on to the standard straps, so swapping out the standard straps for the fat bike straps is the best option. What is the width of the tires on your e-bike?

Recommended Bike Rack and Fat Tire Adapter That Will fit 4.8 Tires
There are some great bike racks and racks with adapters that will work with your 4.8" tires, though the Kuat Transfer 2 # KU74FR will only accept tires up to 4.5" wide with the adapter. I highly recommend checking out the Kuat NV 2.0 # BA22B, which comes with an adapter to carry one fat bike with 4.8" tires, though if you needed to carry a pair of fat bikes you could add the Phat Bike Adapter Kit for Kuat Bike Racks # APBK. The Kuat NV is a premium rack that uses ratcheting hooks to grasp...

Recommended Best Bike Rack For 2008 VW New Beetle Convertible
There is not a trunk mounted bike rack option for the 2008 VW New Beetle Convertible, so I recommend we start with the Draw-Tite Sportframe Trailer Hitch Receiver - Custom Fit - Class I - 1-1/4" # 24679 which is a confirmed fit. Then the bike rack I recommend the Kuat Sherpa 2.0 2-Bike Platform Rack - 1-1/4" Hitches - Tilting - Aluminum - Black # SH12B. This is a light weight rack at 32 lbs and is an easy tool free installation. This carrier will carry 40 lbs per bike and has an integrated...

E-Bike Rack Solution for 60 lb E-Bike with Fat Tires
The Sherpa does not have the weight capacity for a 60 lb bike nor does the fat tire adapter part # APBK work with the Sherpa bike racks so you'd need to go with a different rack solution like the Hollywood Racks RV Rider part # HLY64FR. This can fit tire widths up to 5 inches, has an 80 lb weight capacity, and has frame clamps that allow it to fit the typically unusual frame shapes of e-bikes.

Recommended Single Bike Bike Rack for a 50 lbs E-Bike that Fits a 1-1/4" Hitch
All of the hitches for the 2023 Kia Soul like item # C67FR are Class I 1-1/4" hitches so your options are pretty limited. The best e-bike rated bike rack is going to be the Kuat Transfer V2 Bike Rack for 1 Bike item # KU64FR. This bike rack has a 60 lbs capacity and fits tires up to 3" wide. You can install the item # APBK if your tires are larger. The Kuat Transfer V2 item # KU64FR is a wheel mounted style rack so it's going to secure your bike by gripping the front tire.

Yes, it will James. Less than 1/2" isn't going to matter. What size tires does your mountain bike have? The Kuat Transfer V2 Bike Rack for 1 Bike item # KU64FR comes with a cradle that only fits tires up to 3.0" wide. If you have larger tires you'll need the Phat Bike Adapter Kit for Kuat Bike Racks item # APBK. These work with tires up to 4-1/2". What model of mountain bike do you have?

These bike racks mount with a standard locking hitch pin, whereas the Thule Easyfold item # TH903202 has an AutoAttach system.

Can Ramp Be Added to Thule T2 Pro XT Bike Rack
The Thule T2 Pro XTR # TH83JV is a great bike rack but was designed prior to the whole ramp fad that's now taking hold of the bike rack community so the only way to add a ramp to this rack would be to modify something that fits. What I recommend doing is switching to the Kuat NV 2.0 Base # BA22B instead because it's comparable to the T2 Pro XT but Kuat made the Access Ramp # ANVBRB so you can load your heavy e-bikes easier. This has the 60 lb weight capacity same as your current Thule...

Comparison of the Kuat Transfer V2 Bike Rack for 1 Bike VS. Inno Tire Hold Bike Rack for 1 Bike
When choosing between the Kuat Transfer V2 # KU64FR and the Inno Tire Hold # INH110, there are a few differences to consider. While both racks have a weight capacity of 60 pounds, the Transfer V2 has a slightly larger bike compatibility range than the Tire Hold. It is compatible with tire diameters of 18-29 inches and wheelbases up to 50 inches long while the Tire Hold is compatible with 20-29 inch tire diameters and wheelbases up to 48 inches long. Another difference is the weight of the...

How can I adapt my older Kuat NV 2 to work with fat tire bikes?
I have good news! Kuat does have a solution to your problem. They created the Phat Bike Adapter Kit, part # APBK, which works with most of their older and newer platform bike racks and roof racks. I verified that this kit will work with your NV 2 which was purchased in 2015. (Model number N102.) The installation is simple, uses your rack's existing hardware, and holds tires from 2.5" to 4.8" wide. Keep in mind that this kit will convert one wheel cradle set for use with fat bike tires....

Trailer Hitch and Bike Rack Recommendations for a 2023 Mazda CX-5
According to my research the only difference between a 2022 Mazda CX-5 and a 2023 Mazda CX-5 is that they offered an additional paint job for the new model year, meaning anything that is confirmed to fit a 2022 should fit a 2023 without any issues. So for your application I recommend the etrailer Trailer Hitch Receiver # e98902 because it features a hidden crosstube with the durable matte black finish. The matte black finish does a better job at blending in with your vehicle trim and offers...

Kuat Transfer V2 3-Bike Rack vs. RockyMounts WestSlope 3-Bike Rack
Those are a couple of great options you mentioned, but between the RockyMounts WestSlope 3-Bike Rack # RKY10223 and the Kuat Transfer V2 3-Bike Rack # KU24FR, I would definitely go with the Kuat Transfer V2 # KU24FR. There are a number of reasons for this, including ease of use, clearances, and fit of bikes. Starting with ease of use, while the WestSlope uses a threaded hitch pin that requires you to use a ratchet like # PTW38106-24 to install, with the Transfer V2 you simply slide its...

Kuat Bike Rack and Swing Away Extender Recommendations for 2021 Ford Bronco with Spare Tire

That said, between the 2-bike versions of these racks, one advantage of the Transfer V2 is its weight capacity; it has a 60 lb per-bike capacity vs. the Sherpa 2.0's 40 lb per-bike capacity....
