Hello Carlos,
The RockyMounts DropTop Truck Bed and Utility Track Bike Rack # RKY57ZR is a Thru-Axle mount, meaning you will have to take off the front tire to hold the bike in place. Fits bikes with a 12-mm or 15-mm thru-axle up to 110-mm wide. I have included a review video, you will see how the front tire is taken off, and you will notice that the back tire of the bike is a fat tire. I have also included an image so you can see how the bike is help in place with the # RKY57ZR. Also, if your bike has a standard fork mount you can use the # RKY1082 to make it work.
Happy New Year! May 2025 be your best year yet! From, your friends here at etrailer!

Hey Carlos, how did the RockyMounts DropTop rack work out with your fat tire bike? Did removing the front tire make loading and securing it easier? Your update could make it easier for others with similar bikes.
