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.
Terry - 03/30/2022


Great products, great price. Worked great on my Kuat Transfer bike rack.


Exactly what we ordered, which is unusual with today's internet


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!


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.


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.


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.

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.


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.


We've ordered several items from the folks. Never disappointed with the process. We believe, 'superior service' should be their motto.


Works perfectly


These FO NOT fit 4 inch tires. Much less 4.5 inch... don’t buy


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.

Excellent product!


Needed one more for 4" fat and simple to use.


Quick and easy way to load a fat bike on a conventional bike rack


Thank you all for a very professional customer service !
Very happy! It’s sooo super awesome NV Kuat bike racks and accessories


Good products use during winter months and work just fine


From start to finish, this purchase from etrailer was a great experience. The salesman that helped me on the phone was really good at finding what I needed. I would definitely shop here again. Great job etrailer.


Great accessory for those with fat-tire ebikes.


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.


Worked out to be the perfect extension for my giant Rad Rover bike tires. Still like new a year later.


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.


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.


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

  • How Long are the Straps on the Kuat Phat Bike Adapter Kit?
    I went to our warehouse to measure the Phat Bike Adapter Kit # APBK and found that the cam-buckle strap measured 26-3/4 inches while the plastic ratchet strap measured 13-1/2 inches. I've added a link to a video review of this product for you to check out.

  • 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....

  • Recommended Hitch-Mounted Bike Rack for 3 Beach Cruisers on 2014 Ford Escape
    To transport your 2-3 Beach Cruisers with Fat Tires on your 2014 Ford Escape, I recommend the Kuat Transfer 3 Bike Platform Rack # KU24FR that is compatible with Class II and larger trailer hitches. This is a great platform rack that will make loading and securing your Cruisers much easier when compared to a hanging rack. Because the bikes will be supported by their wheels, you will not need to worry about keeping the alternative frames of the Cruisers level during transport. This rack...

  • 3 Bike Platform Bike Rack Recommendation for Carrying 1 Fat Bike and 2 Standard Bikes
    We have a 3 bike platform bike rack that has an adapter to be compatible with fat bikes like what you have. Check out the Kuat Transfer 3 Bike part # KU24FR and part # APBK which would be a great option. It only touches the bikes at the tire as well. I attached a review video for you to check out as well. The wheel trays are wider to accommodate fat bikes but they also work great with standard size bikes like the other two you mentioned.

  • What is the Maximum Bike Tire Width that Fits the Kuat Transfer Bike Racks
    Kuat Transfer V2 Bike Platform Rack Item # KU74FR accepts tires up to 3 inches wide right out of the box. Using the Phat Bike Adapter Kit for Kuat Bike Racks Item # APBK increases it to 4-1/2 inches. To be clear the wheel cradles as they come will hold up to a 4-1/2 inch tire but the included straps are not long enough to secure anything over 3 inches in width. If the tires are between 3 and 4-1/2 inches then you would need the adapter.

  • Best Fat Tire Bike Rack with Tilt to Allow Tailgate Access with Bikes Loaded and Rack Tilted
    The Kuat NV part # NV22G can fit tires that are up to 4.8 inches in width as long as you use the Phat tire adapter part # APBK. We also had the chance to demo this rack on a similar Chevy Silverado as yours and we found that it did allow the tailgate to fold down with the bikes loaded. Check out the picture I attached to see that.

  • Will Fat Bike Fit Kuat Transfer 3 Bike Platform Rack
    If the tires on your fat bike are 4-1/2 inches wide or smaller, the Kuat Transfer 3 Bike Platform Rack, part # KU24FR would be a great bike carrier with the Phat Bike Adapter, part # APBK.

    The Kuat Transfer 3 Bike Platform Rack part # KU24FR is compatible with tires up to 4-1/2" wide with the Phat Bike Adapter # APBK. That said, the way the wheel trays are designed it will still work with road bikes that have skinny tires as well because you will notice there is a small channel in the bottom of the tray for this exact purpose. Therefore, you will have no issues using the above for both fat tire mountain bikes and skinny tire road bikes. I especially love the Transfer so...

    The Kuat Transfer 2 Bike Platform Rack # KU74FR can also be mounted on your Toyota Tundra as it is compatible with both 1-1/4" and 2" vehicle hitches. The transfer is a very popular option because it not only looks good but wheel mounts your bike so you preserve your bike's finish. The step-through design and lower profile to the ground make loading bikes easier. Plus it is capable of tilting away with the rack loaded with your bikes. The transfer is also capable of carrying your...

  • Can Kuat NV Bike Racks Carry Bikes with Fat Tires
    The original Kuat NV which was part number N102 required a fat tire adapter part # APBK to carry bikes that have tires that are wider than 3 inches. The adapter fits tires up to 4-3/4 inches in width. The current version of the NV part # NV22G comes with one of these adapters. If you had two fat bikes you'd need to also get an additional part # APBK.

    Thank you for your purchase of the Kuat Transfer 2 bike carrier # KU74FR. This platform rack can be updated for fat bike use with accessory Strap Kit # APBK, which I see you purchased as well. We have not heard of this issue with this rack when it is equipped with this kit and used with a bike that has compatible tire width.

    The Kuat NV 2.0 Base Bike Rack for 2 Bikes - 2" Hitches # BA22B is a great bike rack for 2 electric bikes. Just make sure the bikes weigh less than 60lbs each or remove the battery pack to try to reduce the weight down to the 60lb weight limit which you do not want to exceed. Also make sure your tires are no wider than 3", if they are wider then you will want to add fat tire adapter # APBK which can hold up to 4.8" wide tires.
