This Curt bike rack makes it easy to carry 4 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 4 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 and you can choose between 2 different ways to fold the rack up for storage on your vehicle when it's not in use.

Easily Converts to a 2-Bike Carrier

Carry 4 bikes on this rack for family outings, or easily convert it to a 2-bike carrier for duo or solo rides. To convert the rack to a 2-bike carrier, remove the 2 bolts that hold the outer platform inside the shank of the inner platform. Then simply slide the outer platform out of the shank and stow it in your garage or shed.

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 4 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 4 sets of standard-size wheel holders that fit bike tires up to 3" wide, giving you the option to carry any combination of up to 4 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 masts. 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 masts by removing their pins and clips at the bases and then fold the masts down forward. Then remove the pins from the base of the rack and fold up the carrier.

Anti-Rattle Hitch Pin

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. Because this bike rack has a threaded shank, it is not compatible with standard hitch locks.

Ask the Experts about this Curt Hitch Bike Racks

  • Can the Curt Platform Style Bike Rack for Fat Bikes C18087-FB be Locked to the Trailer Hitch
    There isn't a confirmed threaded hitch lock that works with the Curt bike rack # C18087-FB so what I recommend to secure it and the bikes to the hitch is a hitch lock # e98891. It is also possible to use a very small pad lock through the hole at the end of the threaded hitch pin if you wanted to.

  • Will Swagman XTC4 #S64650 Bike Rack Work With Spare Tire On A 2010 Jeep Wrangler
    I did contact Swagman on your behalf. They recommended referring to the below dimension versus the length of your Wrangler rear swinging door to determine clearance while mounted, folded down without bikes or the spare tire. -The clearance from the receiver bar hole to the first wheel hoop is 11.5" Due to the rise in the shank of the Swagman XTC4 4-Bike Rack for 2" Hitches # S64665, the ability to tilt the rack down would be essential for clearance and this does not provide that....

  • Can I Carry a Beach Cruiser on a Curt Platform Bike Rack
    Yes you can carry your beach cruiser on the Curt 4 Bike Platform Bike Rack # C18087. The cradles adjust to fit different bike widths. I tested out the fat bike version of the rack # C18087-FB and used our fat bike with it. That bike measures 69-1/2" from front to rear tire and it fit just fine. The overall length doesn't change with the fat bike version just the width of the cradle to accommodate the wider tires. I attached a video I made of the fat bike version. You can see in the video...

  • Recommended Fat Bike Beach Cruiser Bike Rack For 2009 BMW X3
    The Thule Apex 4 Bike Rack # TH9025XT and the Thule Helium Aero 3-Bike Rack # TH9043PRO are similar in many respects. They differ in the number of bikes they carry and the materials with which they are made. The Apex is steel and weighs about 44 lbs where the Helium is Aluminum and weighs about 23 lbs. These are both nice bike racks but they will limit you to 35 lbs per bike which is where your fat tire beach cruiser have issue as those bikes are normally heavier than that. If this...

  • Are There Wider Cradles Available for the RockyMounts WestSlope
    There are several bike racks available that re designed to fit the newer larger flat tire bikes there are no replacement saddles available to convert your RockyMounts WestSlope 3 Bike Rack part # RKY10223 over to use them.
