Video Transcript for Saris Freedom Fat Tire Adapter Kit Review

Today I'll be showing you how to install the Saris Fat Tire Adapter Kit part number SA4419. You can see we all ready have the rack installed, now we'll just show you how to swap out the wheel trays. Now this part number is only one set of wheel trays, the manufacturer does recommend that when you're holding one bike or carrying one bike that you carry it on the cradles or saddles closest to the rear of the vehicle. We'll do is just loosen up this yellow knob, push down this yellow button and just slide the tray out. Take the new tray, slide it on and then just tighten it down. Now here on the other side you can see this wheel tray is on the inside of this arm, we are going to have to remove this arm. What we'll do here is just loosen this knob here, push down that button pop this one off and we'll use the Allen wrench and a seventeen millimeter wrench or ratchet whichever you prefer, loosen this up.

Should slide right off then we can remove this other inside wheel tray. Take the new tray, slide it on then just leave this loose so you can adjust it. Slide the arm back on and then tighten it down. If you are carrying a flat tire bike you may need to use the included straps. What we're going to do is just take this end of the strap slide it through, come back up this hole here. Then there's these little tabs in the bottom on the strap if you can see these and those going to give those tug snap this in place.

Then you'll just come around the bike and then flip it in place. Now that we have the trays installed and our straps are undone I'll go ahead and place the fat tire bike into our new wheel trays. I'll just need to adjust this back one just a little bit and with that in place, just make sure that these wheel hooks are extended all the way out. Bring this up, clamp that down then we'll finish off by bringing the cam buckle straps through the rim and spokes. Securing it with the cam buckle and with our bike all loaded up that will complete today's review of the Saris Fat Tire Adapter Kit just part number Sa4419. .

Adapter kit lets you carry 1 bike with fat tires on your Saris Freedom bike rack. Just replace the existing cradles with these larger, deeper cradles designed for fat tires up to 5" wide. Uses existing hardware. Extra-long wheel straps included.


These fat bike wheel trays are excellent. Fit my 4.8 inch tires fine. Fit onto the saris rack easy peasy. Not much else to say. Does what they are made to do and easy to mount and use. I’ve also put a regular mountain bike tire in it and it holds it fine.


Well made and should do what I need!


They work as advertised.


This bike rack was designed for two bikes.
use it for one only fat tire e-bike as it is still within the weight restrictions.
It carries my bike well and I'm pleased with it's performance. My suggestion is to always be within the weight restrictions when deviating from recommended us.


Fat Tire Adapter Kit for Saris Freedom Bike Racks : Zoom, Zoom Shipping


Rocket to the moon quality!! Handles so many different tire sizes what a great bike tool. Takes a beating was easy to install withstands the Minn. weather WHAT else could you want.

No changes AWSOME! Keep bringing it
Ron T - 05/27/2018


So far, so good. Great customer service at eTrailer, they are easy to reach and they do try to get things right. These adapters are essential for the 60 pound bikes that the Freedom rack is designed to carry--the stock cups are just too narrow for any tires wider than about 2". Add their cost to that of the carrier--but still a reasonable price for a very solid, functional rack.


The fat tire adapters for the Saris rack are excellent. You just slide the standard wheel holders off and then slide the fat tire adapters on. They work exactly like the standard wheel holders.


Excellent replacement parts


The fat wheel holders are very easy to install. You do have to use an Allen wrench and a 17mm wrench to remove and replace one of the clamp arms, but it’s simple. It can easily hold the 4.8” tires on my Trek Farley.


I have only received the extra items and not the actual bike carrier.


Love the installation ease.


Great product!! Fits our bikes very wel l!!


Expired services no issues! Would purchase from you again!


Exactly what I needed! Makes carrying my fat-tire bicycle simple!


Great service


This product is still working well for me. My only complaint is that the tire straps and support straps can be hard to get latched. Those could have a better design. As we get older are hands are not what they used to be.

easy to put on




great service, product worked great!!!!

  • Fat Tire Adapter Solution for Saris Freedom Bike Rack
    If you have a fatter tire than what the # SA25640 would allow you'd need to go with the Saris Freedom Fat Tire Adapter part # SA4419 which is a wider tray with a longer strap like what you'd need.

  • 2 Bike Rack Recommendation for Carrying Electra Townies with Fenders and Balloon Tires
    The best rack style for a bike like your Electra Townie that has fenders would be a platform bike rack that uses a hook to grab the frame of the bike and hold it to the rack. One very popular option is the Saris Freedom part # SA4412B. And then for an adapter to allow the wider tires to fit on the rack you'd want the Fat Tire adapter part # SA4419.

  • Distance Between Bikes on the Saris SuperClamp Platform Bike Rack
    I can't say for sure if your bike's pedals will be an issue on the Saris SuperClamp EX # SA4025F because there really isn't a way to know without putting the bikes on it. The wheel trays do slide to help prevent contact however, they will be pretty close together and it could be an issue for you. Between the wheel scoops from center to center there is 8 inches. You'll also need the Fat Tire Adapter # SA4419. The SuperClamp EX has a max weight capacity of 60 pounds per bike, which is...

  • Will the Saris Freedom SuperClamp EX Be Able to Accommodate 4 Full Size Mountain Bikes
    The Saris Freedom SuperClamp EX # SA4026F is a great bike rack that can accommodate almost any bike since it is a wheel mount bike rack. As long as your bikes are within the specs for the SuperClamp then you will have no problem fitting 4 mountain bikes on it. The weight capacity for the 2 inner positions is 60 lbs per bike and the weight capacity for the 2 outer positions is 35 lbs per bike. The max wheelbase that the SuperClamp will hold is 48 inches with a max tire width of 4-1/2 inches....

  • Bike Rack That Fits Class II 1-1/4 Inch Hitch That Works With an Electric Bike That has Fat Tires
    From my research it looks like a Sondor electric bike weighs 55 lbs and has 4.9 inch tires. A bike rack that fits in your Class II 1-1/4 inch hitch and would work great is the Saris SuperClamp EX # SA4025F; it is a 2-bike rack with a weight capacity of 60 lbs per bike and can accommodate your fat tires with the use of fat tire adapter # SA4419. The SuperClamp has a built-in anti-rattle hitch lock to secure the rack to your vehicle and an integrated cable lock to secure your Sondor to...

  • Recommended 2 Bike Rack For Step-Thru Bike On 2018 Kia Niro
    For your 2018 Kia Niro, I recommend the Saris Freedom Bike Rack for 2 Bikes # SA4412B. This has a weight capacity of 60lbs per bike, so you won't have any stability issues with your bikes since they are less than 60lbs each. The Saris would not require an adapter bar, however, the Hollywood Racks Sport Rider SE2 would require one. If your ebike tires are over 2 1/4" wide, I recommend the Fat Tire Adapter Kit For Saris Freedom Bike Racks # SA4419. This adapter kit would allow up to...

  • Hitch and Bike Rack Recommendation for Rad Rover E-Bike for 2017 Chevy Bolt EV
    For your 2017 Chevy Bolt the Draw Tite hitch part # 24956 is a confirmed fit and would be the correct hitch for carrying a bike rack. The Saris Freedom part # SA4412B will work great in this hitch and has a 60 lb capacity. Now if your tires are wider than 4-1/2 inches you'd need the fat tire adapter part # SA4419 otherwise it'd be good as-is without the adapter.

  • Recommended Class I Bike Rack for Heavy E-Bikes
    Thank you and welcome back! Yes, I can confirm that the Saris SuperClamp EX Bike Rack item # SA4025F and your hitch have enough capacity to carry your 55 lbs E-Bike. The Saris has a 60 lbs capacity per bike and does fit a class 1 hitch along with a class II and III if you would like to use it on different vehicles. This is a wheel mounted bike rack that fits tires up to 4-1/2" wide. It has integrated locks to secure both your bike rack and bikes from theft. The Draw-Tite Hitch item #...

  • Recommended 1-1/4" Bike Rack for a Women's Cruiser Bike w/ Fenders
    A great bike rack that will work with your mountain bike and your women's cruiser bike with fenders is the Saris Freedom Bike Rack for 2 Bikes item # SA4412B. This bike rack fits both a 1-1/4" and 2" receiver so you will be able to use it on your Subaru and it gives you options for other vehicles as well. I recommend this bike rack because it is a frame mount style, that will prevent damage to your cruiser's fenders, and it will also work well with your mountain bike. It has a 35 lbs...

  • Comparison of Saris SA4026F SuperClamp EX 4 Bike and SA4414B Freedom 4-Bike Rack
    The difference between the Saris # SA4026F Saris SuperClamp EX 4 Bike Platform Rack and the Saris # SA4414B Freedom 4 Bike Platform Rack is how the bikes are held to the rack. The # SA4026F holds the bikes by the wheels/tires with no frame contact. This is good for carbon fiber framed bikes that don't do well in a carrier that has direct frame contact. The # SA4414B Freedom holds the bikes from the top tube or down tube. This rack would be a good choice for cruiser-type bikes with fenders,...

  • Will E-Bikes be Easy to Load Onto Saris Freedom 4-Bike Rack & Are Fat Tire Adapters Available
    The Saris Freedom 4-Bike Rack # SA4414B is one of my favorites, and so long as you don't have any issues lifting up the bikes, it isn't difficult at all to load them behind the vertical post so your bike is closest to the hitch. The wheel trays are large and you will be able to easily place your bike right in. You can also get fat tire adapters, but can't get the rack with just one set of wheel holders for fat tires, you do need to get them extra with the Fat Tire Adapter Kit for Saris...

  • Can The Wheel Trays On The Saris Freedom Handle My Salsa Bike?
    We have carried the Saris Freedom, like the # SA4412B, for a number of years now and I have personally not had any calls or emails regarding issues with the wheel trays. This goes for replacements ( # SA25640 and # SA25641) and the fat tire adapters ( # SA4419). However, I have had a few people tell me the straps can be a little difficult to use when its cold out and they are brand new, but with use they do get more flexible so I would call it more of a very minor annoyance at first rather...

  • Best Bike Rack for Two Biktrix Stunner LT Bikes
    I would love to help but it is not advised to use a wheel mount bike rack with fenders so the RockyMounts MonoRail 2 Bike Platform Rack part # RKY10003 is not your best option. Instead, I recommend taking a look at the Saris Freedom 2 Bike Platform Rack part # SA4412B. This option will allow for a 60 lb bike. It can accommodate 5" wide tires with the # SA4419 Adapter so there will be no issues with your two Biktrix Stunner LT bikes using this combination. The frame clamps will however need...

  • E-bike Rack Recommendation for 60 lb Bikes in Class I Trailer Hitch
    The Saris SuperClamp EX part # SA4025F can fit 1-1/4 inch hitches as long as they are Class II (you may have a Class I hitch so you'd need to check), it has a 60 lb per bike capacity, and can fit tires up to 4-1/2 inches wide so there's a possibility it could work for you. If your tires are fatter than 4-1/2 inch you'd need the fat tire adapter # SA4419 as well. But if your vehicle has a Class I hitch this would not be the bike rack to go with. If this is the case the best option is the...

  • Saris Freedom Bike Rack Compatibility With 4 Inch Wide Fat Bike Tires And Electric Bike
    The Saris Freedom SuperClamp EX2 # SA4025F will work for bikes with up to a 4-1/2 inch wide tire. If you have tires over 4-1/2 inches then you will also need the Fat Tire Adapter Kit for Saris Freedom Bike Racks # SA4419 compatible with tires up to 5 inches wide. Standard tires will fit fine in either holder. Another option is the Saris Freedom 2 Bike Platform Rack for Fat Bikes # SA4412B-FB which can accept bikes with tires up to 5 inches wide.

  • Easy to Use Platform Style Bike Carrier for Bikes with Fat Tires
    The upright arm on the Saris Freedom 2 Bike Platform Rack for Fat Bikes part # SA4412B-FB can be tilted downward toward the ground to eliminate lifting the bike up and over the arm but the bike will need to be tilted towards the vehicle to allow for the frame mount clamp to clear the bike while folded. A better option for you would be to use the Saris Freedom SuperClamp part # SA4025F as this bike rack will not require you to lift your heavy fat bike up and over a tall upright arm. This...

  • Are Fat Tire Cradles on Saris Freedom Bike Rack Compatible with Smaller Tire Widths?
    The Saris Freedom 2 Bike Platform Rack for Fat Bikes - 1-1/4" and 2" Hitches - Frame Mount # SA4412B-FB will work well for all the bikes you referenced. The fat tire cradles work fine with smaller tire widths. If you instead want the Saris Freedom 2 Bike Platform Rack - 1-1/4" and 2" Hitches - Frame Mount # SA4412B, then you can just trade out one set of the cradles with the Fat Tire Adapter Kit for Saris Freedom Bike Racks # SA4419 and you'd be all set.

    The Saris SuperClamp EX 2 Bike Platform Rack - 1-1/4" and 2" Hitches - Wheel Mount # SA4025F is in fact setup for transporting most electric bikes. It has a weight capacity of 60lbs per bike which is enough for the majority of electric bikes, and it fits bike tires up to 4-1/2" wide. If the bike's tires are wider than 4-1/2" then you can add Fat Bike Kit # SA4419 which allows for up to 5" wide tires.

The Saris Freedom fits a 2" receiver and has a 60 lbs capacity per bike on the inner two holders and a 35 lbs capacity per bike on the outer two holders.

From the center of the hitch pin hole to the closest wheel tray measures 12" and it also has a 5" rise in the shank so it will help out with that clearance. The only thing you'll need to keep in mind is that this rack is compatible with up to 4.5" tires. Since yours are 4.6" you might be able to get them to work but you might...
