This Curt bike rack makes it easy to carry 2 fat bikes on the back of your vehicle. The platform-style rack is easier to load than a hanging rack because you don't have to lift your bikes nearly as high to get them into place. Ratcheting hooks and wheel hoops accommodate 2 bikes of most shapes and sizes. The entire rack tilts down for easy access to your cargo area, even while the bikes are loaded. And you can choose between 2 different ways to fold the rack up for storage on your vehicle when it's not in use.

Ratcheting Frame Hooks

Each center mast has 2 ratcheting hooks that move up and down independently of one another. This allows you to carry up to 2 bikes of different heights or with different frame styles. The hooks firmly grip your bikes by the top tubes, and they are cushioned to protect your bike frames from scratches and scuffs. Once you slide the hooks into position, just lock them in place.

Adjustable Wheel Hoops

Curt platform bike rack cradles

The wheel hoops are designed to fit fat bike tires up to 4-7/8" wide. These sturdy, adjustable wheel hoops let you carry bikes of different lengths. Use the built-in knobs to loosen the hoops. Then slide the hoops to the desired position along the platform base and tighten them into place.

The rack also comes with 2 sets of standard-size wheel holders that fit bike tires up to 3" wide, giving you the option to carry any combination of 2 fat or standard bikes.

Tilting and Folding Design

Curt platform bike rack in tilted position

The entire rack can be tilted down - away from your vehicle - so that you can easily access your rear cargo area, even when your bikes are loaded. Just pull the pin at the base of the rack to tilt it down.

Curt platform bike rack storage options

There are 2 ways that you can fold up the rack to store it on your vehicle when it's not in use. Option 1 lets you fold the cradle arms up towards the upright mast. Simply remove the pins and fold up the arms. Then replace the pins to secure the arms in the upright position. Option 2 lets you fold the rack up against the rear of your vehicle. First, lower the center mast by removing its pin and clip at the base and then fold the mast down forward. Then remove the pins from the base of the rack and fold up the carrier.

Anti-Rattle Hitch Pin and Adapter Sleeve

Curt platform bike rack anti-rattle hitch pin

This rack comes with an anti-rattle hitch pin. The threaded pin holds the bike rack in your hitch, and it reduces noise and movement of the rack inside your hitch. An adapter sleeve is included as well, which allows the rack to fit either a 1-1/4" or a 2" hitch receiver. Because this bike rack has a threaded shank, it is not compatible with standard hitch locks.

- C18085-FB

I received the C18085-FB Fat Tire Bike Rack yesterday. It took me about 1/2 hour to assemble the pieces. The instructions could be a bit more clear, especially when it comes to the washers but I figured it out. It appears to be a quality product. I have not had the chance to try it out but eTrailer was very helpful in helping me on the purchase. It came in 2 boxes because I ordered the Fat Tire mount which included for regular or mounting bike tire holders as well. You would pay an additional $50.00 or so to get the tire holders that are required for fat tire bikes. My tires width measures 4" wide. Another nice feature is it can support 1 1/4" or 2" hitches. It is harder to find a bike rack for fat tire bikes that would work with a 1 1/4" hitch. Most only support 2".

Great! I would definitely buy this or other products again from eTrailer

- C18085-FB

easy to put on hitch. folds to a compact size for storage. very pleased with it.

- C18085-FB

Great bike rack. Came with two sizes of wheel widths one set for fat tire bikes. Went together easily and didn’t wobble.

- C18085-FB

I bought this for our fat bikes after a lot of frustration with our previous hitch rack that was your typical hang by the frame style. This rack is so easy to use with two fat bikes and allows easy access to the hatchback of our SUV with removing just two pins even while loaded with bikes. It also sits high enough that it does not scrape the ground when backing out of steeper driveways like our other rack. I would recommend this rack to anyone looking for a platform rack for any style bike (we bought the additional tire platforms for our other bikes with narrower tires).

- C18085-FB

Very Secure and solid I have 2 E-Bikes fat tire It a bike rack you can trust Locks them on securely

- C18085-FB

I have not actually used the bike rack yet. Having said that, it is a solid heavy duty unit that went together nicely.

- C18085-FB

Nice design, however, would prefer the carrier be stronger and less movement on the hitch.

- C18085-FB

Works good.

- C18085-FB

The rack arrived on time, was very easy to install and is just great. The price was so affordable, the video very informative, the overall experience was beyond my expectations. I am 80 years young and was hesitant about purchasing an electric bike, so this was a new experience for me. Thanks.

- C18085-FB

I received it in just 2 days, I just installed this rack with no issues other than it rocks really bad in the receiver.

Thank you for your review. This curt bike rack part # C18085-FB comes with an adapter to make it fit into a 1-1/4 or a 2 hitch. I am not sure which size hitch you have but you may want to make sure the adapter is flipped to the correct size to fit into your hitch. If you have a 2 hitch and the adapter is on the 1-1/4 side then it will rock back and forth in the hitch. If you have it on the correct side then an anti-rattle device such as a roadmaster quiet hitch will help. The quiet hitch will tighten up the space between the bike rack and the hitch receiver. If you have a 2 hitch then you will need part # RM-061
Roadmaster Quiet Hitch for 2" Trailer Hitches
. If you have a 1-1/4 hitch you will need part # RM-061-125
Roadmaster Quiet Hitch for 1-1/4" Trailer Hitches

  • Recommended Tray Style Bike Rack for a 2 Trailer Hitch and Fat Tires Bikes
    Out of the Curt 2 Bike Platform Rack # C18085-FB and the Hollywood Racks Sport Rider SE # HLY84FR I highly recommend the Hollywood Racks because it is compatible with up to 5" wide tires (instead of 4-7/8") and has a weight capacity of 80 lbs per bike over the 45 lbs per bike the Curt has to offer. The Sport Rider SE2 also comes with both bike and rack locks as well as a limited lifetime warranty where the Curt only comes with bike locks and a 1-year limited warranty. One thing to note...

  • Replacement Parts for Curt Platform Type Bike Rack
    I'm sorry to say that Curt doesn't offer replacement parts for their # C18085-FB bike rack which is sold only as a fully complete rack. Your best bet would be to try to straighten the shank so that it's usable or replace the rack entirely with a name brand rack from a manufacturer that does stock spare parts like Thule, Yakima, or Swagman. The Swagman # S64678 Current would make a good replacement. The Current works in 1-1/4 or 2 inch receivers and can accommodate bike tires up to 5...

  • How to Lock Curt 2 Bike Platform Rack for Fat Bikes C18085-FB
    Curt's 2 Bike Platform Rack for Fat Bikes # C18085-FB includes an anti-rattle threaded hitch pin that will reduce motion of the rack in your hitch but this feature prevents use of a standard hitch lock. No worries though since you can use a simple cable lock such as # e98891 (10-foot) or # C23666 (6-foot) to both lock your bikes to the rack and also to lock the rack to your hitch receiver by running the cable through a safety chain loop on your hitch. If you prefer a 2-bike Fat Bike...

  • Recommended Hitch Mounted Bike Carrier For 4 Inch Tire Fat Bike Beach Cruiser
    For your beach cruiser with 4 inch tires, I recommend the Curt 2 Bike Platform Rack for Fat Bikes - 1-1/4" and 2" Hitches - Frame Mount - Tilting # C18085-FB. This bike rack will fit tires of up 4-7/8 inches wide and will hold the bikes by the frame in case your beach cruiser has the typical fenders. This Curt rack will fold close to the car when not in use to give you the most clearance for your garage door and it is compatible with bikes up to 45 lbs each. I've attached a video to assist.

  • Carrying Two Fat Bikes with the Curt 2 Bike Platform Rack with Adapters
    If the Curt 2 Bike Platform Rack, part # C18085 can carry two fat bikes will be determined by the weight of the bikes. Each position is limited to 45 pounds, and the individual bikes in this position can't exceed this weight capacity, even with the fat bike adapters, part # C18091 equipped onto the rack. If you're buying for two fat bikes, you can save a little bit by buying the dual Fat Bike kit, part # C18085-FB. If you have heavier fat bikes, and this rack won't work for you, I recommend...

  • Can Bike Rack Adapter for Cargo Carrier Fit Fat Tire Bikes
    The Bike Rack Adapter for Stromberg Carlson Hitch Mounted Cargo Carrier # CC-125, which fits the 23 x 60 Stromberg Carlson Cargo Carrier for 2" Hitches # CC-100, is only capable of fitting bikes that have tires up to 2-1/4" wide, and there isn't an adapter for fat tire bikes. So in order to carry fat tire bikes you do have to use a dedicated bike rack. For a fat tire bike rack, I highly recommend checking out the Curt 2-Bike Rack for Fat Bikes # C18085-FB or Hollywood Racks TRS 2-Bike...

  • Will Fat Bikes Fit the Swagman XTC-2 Bike Rack
    The standard wheel hoops on the Swagman XTC-2 # S64670 accept tires up to 2-1/2 inches wide but there are other hoops available for the rack sold separately. Wheel hoop set # S64674 will fit the rack and will accept tires up to 5 inches wide. These are sold as a pair. The similar Curt bike rack, # C18085-FB, will accept tires up to 4-7/8 inches wide right out of the box. I have included a link to a video review of this rack for you.

  • Maximum Tire Width for Curt 2 Bike Platform Rack
    The Curt 2 Bike Platform Rack # C18085 is compatible with tires up to 3" wide. Anything wider than that and you need the Fat Bike Adapter Kit # C18091 which can accommodate tires up to 4-7/8" wide. If you don't already have the bike rack and you know you need the Fat Bike Adapter Kit then you can actually purchase the bike rack # C18085-FB which is the exact same bike rack, just with the adapter kit already installed.

  • Hitch Lock Compatible with Curt Bike Rack
    The Curt 2 Bike Platform Rack for Fat Bikes - 1-1/4" and 2" Hitches # C18085-FB can use the Anti-Rattle Hitch Lock for SportRack Bike Racks and Cargo Carriers - 1-1/4" and 2" Hitches # SR0901 because the threaded shank of the bike rack is compatible with the threads on the locking bolt. The Stainless Steel Locking, Anti-Rattle Threaded Hitch Pin for 2" Trailer Hitches # SR25219 is not compatible with the bike rack.

  • Will the Hollywood Racks Destination Accommodate a 4-Inch Fat Tire Non-Electric Bike?
    I think I have a couple options for you. Unfortunately, the Hollywood Racks Destination # HLY94FR cannot securely hold a 4-inch fat tire bike. For a 4-inch fat tire bike hitch-mounted rack, I recommend the Curt 2 Bike Platform Rack for Fat Bikes - 1-1/4" and 2" Hitches # C18085-FB. The Curt 2 will give you plenty of room to mount your 4-inch fat tire into the wheel hoops. The Curt 2 also includes integrated bike locks for extra security.
