Video Transcript for Fat Tire Adapter Kit For the Thule T2 Bike Rack Review

Hey guys. Matt here at Today we're going to be going over the Thule Fat Tire Adapter Kit for the Thule T2, part number TH919. Now, the Thule T2 does come standard with the wheel cradles that accommodate these skinny road bike tires and mountain bike tires up to three inches wide. We can see here behind me, we have our fat tire bike, which the fat tires here are about five inches wide, so we're going to need that fat tire adapter kit to properly hold this bike in place. Now, down here at the bike rack, we're just going to give you an idea of the difference between the two-wheel trays. This wheel tray here is the standard wheel tray that comes with the Thule T2 ,and then you can see how much wider the adapter is. The neat thing about this adapter is, yeah, it does accommodate the bikes with the five-inch fat tires, and also still has that same grove in there to accommodate those skinny road bike tires. The first thing we're going to do is just show you how to swap out the front end back wheel tray. To do this, we'll need to be on the underside of the rack and remove these two bolts here on the bottom.

Now, you can use a five-inch screw driver or a socket to remove these two bolts here on the bottom, and set this aside because these bolts will be reinstalled. Now, we'll go ahead and pop it off, and we'll take the adapter, slide the two pegs down into the holes. You can and actually install the incorrectly, so when you install this, the part with the wider back needs to be closer towards the middle of the rack. Now, we'll go ahead and reinstall the hardware on the bottom side of the rack. Now that we got the front part installed, we're ready to install the back wheel cradle. Now, there is two separate settings for the strap just to accommodate wider bike tires. For example, in this setting that we have here, we have the strap actually run through the entire back and bottom piece.

What we need to do is push in this gray button, open up the strap, and remove this runner tow out here, and we'll need to push out, you could see the end of the strap coming out right here, and to remove this. Ready to install it this square section here. That's going to give us all that extra slack for our lager fat tire bike. Now, we'll go ahead and install it unto the rack. First thing we'll do is pop off this plastic end cap, and then you could see that there's a screw and knot in here which we need to remove. Set that aside to be reinstalled.

We will slide this off, and slide a new one on. Then we'll replace that screw and knot as well as the plastic end cap. Now that we have both pieces of the adapter installed, I'm going to give you an idea of what the tire would look like if you did not have the adapter. Clearly, you can see this three inch wide standard tray that comes with the Thule T2, does not accommodate the five-inch fat tire bike. Now, we already the front arm unfolded and extended. Go ahead and undo the back tray strap and lift the bike up unto the rack. Now, you can see with the new adapter, it nicely accommodates this five inch wide fat tire bike.

Go ahead and extend the wheel hook up, clamp it down. We'll slide this tray out to accommodate the length of the bike. Take this strap and go through the room around the spokes, insert it back into that can buckle, make sure that this head here is over the rim just to protect it. Hold it tight. Now that we got our bike all loaded up, we'll go ahead and take it out on our swalom 00:04:03 and our bump course to show you how it performs. That will complete today's review of the fat tire adapter kit from the Thule T2 Platform Style Bike Rack, part number TH919. .

Transform your Thule T2 hitch-mounted bike rack into a carrier for your bike with fat tires. Just swap the existing wheel holders on your rack with these larger, deeper wheel holders to carry 1 bike with a fat tire. No additional hardware required.


Just what I needed to upgrade my Thule T2 Classic bike rack to support my 4" fat tire ebike. I did have trouble with the rear tire strap, though. It's too short as shipped - only 12.5" instead of 18" as described.

I called eTrailer support who was going to send me a new 18" strap. I decided to remove the rear tire support and disassemble it to see what's going on. Turns out the strap can be installed in two positions (the instructions don't mention this) and Thule installs it in the shorter position for some reason. Here's how to change it:

1. Remove the rear tire holder from the rack.
2. Remove the four Phillips head screws.
3. Pry the two halves apart just enough to remove the strap from the bottom of the holder and install it on the side of the holder. Be careful not to pull the two halves completely apart to ease reassembly.
4. Secure the four Phillips head screws.

This will make the useable length of the strap 16" instead of 12.5".


During the plandemic I found a used hitch mount bike carrier which I was able to modify with these parts to successfully carry my fat tire Ebike. Totally worth it!



no problems!


Easy to install, took less than ten minutes from the time I picked the box up, until I had my bike loaded. My tires fit great, and loading takes so little time. I do miss the lever type latch from the original setup, which allowed to grip a bit tighter, but running 10psi allows me to get these cinched down very securely!
Overall, it works great, gave new life to my 12 year old rack!


So nice to have parts for fat tires.
didn't have to buy a new rack.


Ordered the 919 fat tire kit, shipping was fast and it fit good. Installed in just a few minutes, could not be happier. I will order from ETRAILER again. Thanks ETRAILER.




Easy install works great on fat tires


I upgraded my old Thule rack with this Fat Tire adapter. I like it much better than the brand-new rack I just purchased for our other car that supposedly accommodates Fat bikes (from another manufacturer) - much better fit and easier to use.


Quick delivery to Maryland Heights.


I have a Thule 917XTR, and needed the fat tire adapter kit. Took about 15 minutes to install. The front wheel "cup" is nice and wide, easily accommodates 4 inch Dillinger tire. I had to adjust the length of the rear strap (loosen the four screws and slide the strap up to the next position) to accommodate rim/tire size.

I actually think the fat tire rear strap assembly is a better design than what was originally on the rack. Good Job Thule.


I travel with other people to ride trails near and far. We all ride different bikes and I have several friends who ride fat bikes so adding the option to haul a fat bike on my Thule 917XTR-T2 was a no brainer. The tray takes up to 5" wide tires and still has the ability to carry a mountain bike and even road bikes with the slender groove in the tray. The installation was very easy and took just minutes. A great product that makes my Thule rack even more versatile.


I bought it for the wheel holding end, not the fat tire feature. Both of the mechanisms on an older, better, style holder failed, and this was the only style available. The older version was an easy, one-handed version. Only with gyrations can I open this style with one hand. But usually I have to free both hands to open the strap. However it does what it needs to do.


Great product and fast delivery. Enabled me to modify thule bike rack to facilitate use for fat tires on my himiway electric bike. Thanks guys for another great job.


These fat tire adapter's work as advertised. Great addition!


Quick and easy to replace the older, narrow trays. My 4" tires fit with room to spare so the 4.8" tires should fit as well. Had to replace my older ratchet arm with the newer, longer arm in order to load my fat bike. Received order very quickly.


It's to bad I couldn't find just the rear tire cradle. I had to purchase a fat tire kit. The front tire cradle is for a fat tire. Wasted money.


Fantastic adapter for fat bikes that also will hold every other type of bike you have.


This was an item that saved from having to buy a whole new carrier for my Fat tire ebikes. Super easy to replace and we’ll made


The rack works fantastic, very sturdy and holds the bikes securely. Very easy to load and unload.


We got a couple fat tire bikes and these were an easy change out.


Perfect. Exactly what I was looking for



After a year of use. Still a quality product that I would highly recommend. My fat bike, tri bike and road bike fit securely as well as my wife’s beach cruiser.


Fit well on my old rack and works for my aventon adventure. Very easy install, good quality


As described with lightening fast delivery.
Love the info videos that most products have.


Worked perfectly and arrived in a timely manner


It looks like what I wanted, I have not assembled it yet.

  • Fat Bike Adapter Recommendation for Thule T2 Classic Bike Rack TH9044

  • How to Use Fat Bike Adapter on the Thule T2 Classic 2
    The wheel strap for the rear wheel included in the Fat Tire Adapter Kit part # TH919 should be plenty long for most fat tire bikes. It could be that you are not using the strap correctly as this would in turn cause it to appear too short. You will need to completely remove the strap from the rear wheel retention device. It will slide out just below the ratcheting buckle. Once removed, you simply need to slide it back in on the opposite side of the rear wheel retention dive where there is...

  • Fat Tire Adapter for a Thule 2 Bike Platform Rack
    The only Thule rack that has a fat tray upgrade is the Thule T2, and is available as part # TH919. This is compatible with models that have been discontinued. Beyond this, the Thule racks normally are compatible with up to 4 inch wide wheels.

  • Replacement Front Wheel Cradle for Thule T2
    There are not typically straps on the front cradle of the Thule T2, so the # 853-5958 will not have attachment points for any straps. The front wheel is secured with the ratcheting arm of the T2 with downward pressure and no need for a strap on the wheel; the rear wheel simply sits in the cradle and is secured with the strap. If you wanted to replace the rear cradle instead that is not sold as a standalone part- you would need to purchase a new front and rear replacement cradles with...

  • Upgrading Old T2 Ratchet Arms and Wheel Trays to Be Compatible with 26 Inch Wheels with Fat Tires
    The Thule T2 is the older style and the T2 Classic # TH9044-TH9046 and T2 Pro XTR # TH83JV are the newer style. The newer T2 Classic and the pro xtr can accept tires up to 5 inches wide but it does require changing the strap location. I've attached a photo to assist. The older T2 requires the Fat Tire Adapter Kit for Thule T2 Platform-Style Bike Rack # TH919 which will work in the same way as the photo attached to accommodate your 4.8 inch wide tires. Since you have the older version...

  • Replacement Thule Wheel Trays for Fat Bike Compatibility
    For your Thule platform bike rack, the wheel holders/trays you need will depend on your bike rack. It sounds based on your description that you have the original T2 or the T2 Classic which are stock compatible with tires up to 3 inches wide. If you have the T2 Classic like # TH9044-TH9046, you will use the Fat Tire Adapter Kit for Thule T2 Platform-Style Bike Rack # TH919. If you have a different Thule bike rack, let me know the model and I'd be happy to assist.

  • Replacement Wheel Cradles for Old Thule DoubleTrack Pro 9054
    The Thule DoubleTrack Pro TH9054 was discontinued by Thule a while ago. We still have limited stock of some of the replacements parts but not all of them. The Replacement Front Wheel Holder for Thule DoubleTrack Pro 2 # 7524600001 is a fit for your bike rack as well as the replacement wheel strap # TH8542378001. We no longer carry the replacement rear cradles though.

  • Replacement 5/16"x1" Cutting Screws For Thule Fat Tire Adapter Kit
    We have the screws you are looking for! To replace the two screws that mount the Fat Tire Adapter Kit # TH919 you will need two of the Replacement Slotted Cutting Bolt # TH34FR.

  • Solution For Thule T2 Bike Rack When Arm Doesnt Want to Fit Over Tire After Fat Tire Adapter
    I spoke to my contact at Thule and she informed me that the problem you described would indicate that you have the older style T2 bike rack (older than 2012) which was not designed for use with the fat tire adapter part # TH919, but can easily be made to work with the correct replacement part. All you need is the Replacement Locking Ratchet Arm part # 752-1272-001. This will replace what you currently have on your rack and will allow the arms of your rack to fit over the fat tires of your bike.

  • Fat Tire Adapter Kit Needed for Older Thule T2 Bike Rack
    The Fat Tire Adapter Kit # TH919 and Locking Ratchet Arm Assembly # 752-1272-001 will work if you have the Thule T2 bike rack part TH917XTR or TH916XTR. There have been a few different models of the T2 bike rack so if you can verify that's what you have then you're good to go! If you have something else just let me know what the model number is and I can see if we have a replacement that will fit. I have attached a photo of the T2 that these parts fit for you to reference and compare with...

  • Fat Tire E-Bike Rack Solution For Bike that Weighs 64 lb
    The Thule T2 Classic Fat Tire Adapter part # TH919 has the same weight capacity as the bike rack # TH9045 that it fits which is 60 lbs. So if could remove about 4 lb from the bike you'd be okay to use it. Or you'd have to go with an e-bike rack that has the weight capacity you'd need as well as is compatible with fat bikes like with the Hollywood Racks RV Rider # HLY64FR.
