Dimensions

This fork-mount bike rack can be mounted anywhere in your truck bed, or on nearly any stable, flat surface. Simply place the rack where you want to install it, mark and drill the holes, and bolt it in place with the included hardware.


Dimensions

It also installs easily in your vehicle's utility track. Insert the track plates into the track, pass the Torx bolts through the mounting holes on the rack, and thread them into the track plates. Slide the assembly anywhere along the utility track and tighten the bolts with the provided Torx key.


DriveShaft HM Shims

To secure your bike, open the cover, pull back the cam lever, and open the top cap. An overmolded TPU shim lets you drop in 12-mm and 15-mm axles, and you don't need to swap out shims. Set the axle into the opening and close the top cap. If it's too loose or so tight you can't close the top cap, rotate the cam lever until the cap fits snug around the axle, and close the cover. A lock on the cover helps deter theft of your bike.

Not your fault but Rocky Mount. Doesn't really fit fork well as there is MUCH play and screwed in a far as one can go. Is not a 1 fit all for 12 or 15. Needs an additional gasket/grommet to securely hold. With all the extra play I can see the front fork breaking from stress in moving around.



by:

This is an awesome product! I have been using it regularly for the last week and it is spot on. Easy to install and use as well!

The mount works great, but the locks are not very good. They are difficult to work and the key broke off in the lock a month ago, so I can no longer lock my bikes in the truck bed.



by:

My older bicycles are quick release and my older bike mounts won't work with the newer bikes that have through axles. I looked at a lot of solutions and was overjoyed to find this one, with adjustable tension and non-metal inserts to protect the axle.



by:

Great product. I just this in my truck bed to hall my bike instead of always having to use my hitch mount bike rack. Quick and easy and having the lock on it is a big bonus. Highly recommend.



by:

Sure beats trying to lift the bike and thread a thru axle through a close tolerance bushing. I didn't need the locks or other hardware. Very well made, but it is pricey. I wish the mounting holes were slots, which would allow turning the handlebars to avoid bars of the adjacent bike.



by:

I ordered this item thinking they were the only ones who had it unstuck as all the other dealers I knew were out including the manufacturer. E trailer was out as well BUT I got an email informing me that they would follow up with my order and advise me when the item was in stock. Not only did I hear from them but they followed up with the delivery date. WOW, as a small business owner myself I am so impressed with their customer service!! 10 STARS these guys!!!!



by:

Super great bike mount very strong and can handle all thru axles with key lock shipping was exelent and fast we are very happy with this transaction thanks.



by:

The best track bike!!!



by:

I ordered 4 of these and they came in great condition, on time and they took care to send the same key combo for all 4 which is huge. Thanks for the great service!

  • Bike Rack Needed For Hauling An E-Trike And E-Bike On A 2025 Nexus Viper
    Hi Ray, With the Addmotor trike being over 100lbs there really just isn't s good solution here aside from towing a small utility trailer and mounting some fork mounts to the floor of the trailer for the bikes to secure to. Depending on the trailer you go with you could have a ramp to easily load and unload both the bike and trike with ease. A fork mount like the RockyMounts DropTop # RKY57ZR could potentially be used depending on the size of your thru-axle. If you don't already have them...

  • Can the RockyMounts DropTop Locking Utility Track Bike Rack Be Used w/ an E-Bike Without a Battery
    No, the RockyMounts DropTop Locking Truck Bed and Utility Track Bike Rack # RKY57ZR would not work. The 45 lb. weight limit is for the whole bike. With your bike still weighing 50 lbs., that is over the 45 lb. limit. An option you could consider would be using a truck bed carrier like the RockyMounts HotRod Truck Bed Bike Carrier # RKY1087. Because it sits down on the truck bed and is not supported in the air, it does not have a weight limit associated with it. People will often times...

  • Base Dimensions of RockyMounts DropTop Bike Rack
    The base of the RockyMounts DropTop part # RKY57Zr measures 5-1/8 inch by 1-1/2 inch. Since RockyMounts is who rates this the correct capacity would be what they list as 45 lbs.

  • Recommended Fork Block Bike Mount for RockyMounts Truck Bed Track for Honda Ridgeline
    I recommend using the RockyMounts DropTop Locking Truck Bed and Utility Track Bike Rack part # RKY57ZR with the RockyMounts Truck Bed Track for Fork Mount Bike Racks part # RKY10993. It works with thru-axle bikes and quick-release when you add the Dummy Axle with Quick Release Handle part # RKY1082. I have the RockyMounts DropTop on my truck, it's great and I've never had any issues with it. It provides security and it's super easy to use. I have mine mounted on my truck parked outside...

  • How To Mount Thru-Axle Bike On 2020 Toyota Tundra with Deck Rail System
    The RockyMounts DropTop Locking Truck Bed and Utility Track Bike Rack part # RKY57ZR is what you'll use with the deck rail system on a 2020 Toyota Tundra with bike using a thru-axle mount. I actually have this same setup pretty much on my Tundra with thru-axle bike so I can attest to this being a great option. It also has locks for security which was one of the main reasons I choose this.

  • Truck Bed Mounted Bike Rack Recommendation For A 2022 Toyota Tacoma
    I took a look at the Inno Velo Gripper Bike Rack for Truck Beds - C-Channel Mount # INRT202 that you mentioned, and it does not look like it is going to fit your 2022 Toyota Tacoma, however I do have another alternative. Instead, check out the: -RockyMounts DropTop Locking Truck Bed and Utility Track Bike Rack # RKY57ZR. This bike rack will mount into the bed of your truck bed and will fit bikes with a 12-mm or 15-mm thru-axle up to 110-mm wide. Additionally, this rack has a carrying...

  • Does The Dummy Axle With RockyMounts DropTop Bike Rack Provide Ability To Secure The Bike?
    The 9-mm Dummy Axle with Quick Release Handle # RKY1082 will still allow for the front forks to release from the RockyMounts DropTop Locking Truck Bed and Utility Track Bike Rack # RKY57ZR. The forks simply clamp inside the dummy axle like a quick release wheel would. You will want to use a type of Cable Lock # e98891 to secure the bike through the frame to your truck or trailer. I have included a video of the dummy axle being used below so you can see how everything works.

  • Can RockyMounts Truck Bed Bike Rack Carry 3 Bikes in 2023 Honda Ridgeline
    Hi Ken; the RockyMounts Truck Bed Bike Rack for 2 Bikes # RKY67MR can hold three if you add an additional mount like the DropTop # RKY57ZR. The track will install at the front of the bed but it is hard to say on the tailgate since you only have a 64" bed on your 2023 Ridgeline. Based on RockyMount reviews it is pretty hit or miss. Ultimately it will come down to the size of your bikes but I would have the expectation that the tailgate will remain open.

  • Will the Swagman Pick-Up Truck-Bed-Mounted 2 Bike Carrier Fit a 2022 Honda Ridgeline
    I do have a better option for you but I can't confirm the Swagman Pick-Up Truck-Bed-Mounted 2 Bike Carrier part # S64702 for a 2022 Honda Ridgeline. That said, the RockyMounts Truck Bed Track for Fork Mount Bike Racks part # RKY10993 is a much better option as it installs directly into the tracks. It can then be used with a bike mount like the RockyMounts DropTop Locking Truck Bed and Utility Track Bike Rack part # RKY57ZR which is what I use personally and it's great. There's also just...

  • Will The RockyMounts HotRod Work With A 12x122.5mm Thru-Axle?
    I spoke with my contact over at RockyMounts and they told me that the RockyMounts HotRod Truck Bed Bike Carrier - Thru-Axle Mount # RKY1087 is not going to be compatible with your thru-axle. Instead, they recommend using the RockyMounts DropTop Locking Truck Bed and Utility Track Bike Rack # RKY57ZR. This is virtually the same as # RKY1087 but will be able to accommodate your larger thru-axle.

  • Does the RockyMounts DropTop Locking Truck Bed and Utility Track Bike Rack Work w/ Yakima HD Bars
    The RockyMounts DropTop Locking Truck Bed and Utility Track Bike Rack # RKY57ZR is what you'll use with a deck rail system like what is found on a Toyota, Nissan or aftermarket option. The Yakima HD bars will use a standard size t-track channel, which means you would not use the # RKY57ZR. A typical thru-axle mount used on Yakima HD bars would be the Yakima HighSpeed Roof Bike Rack # Y25FR, but this is not the same style as the RockyMounts DropTop Locking Truck Bed and Utility Track Bike...

  • Can I Carry Four Bikes On Truck Bed Mounted Bike Racks In My 2021 Chevrolet Silverados Truck Bed
    You may be able to fit three of the Thule Insta-Gater Pro Truck Bed Bike Rack - 1 Bike, part # TH93VR, in your truck bed, but it will be a tight fit. You can also go with someting like the Swagman Tailwhip Tailgate Pad for Mid-Size Trucks - Up to 4 Bikes - 54" Wide, part # S64761. This will allow you to carry four bikes by hanging over your tailgate on this padded carrier. Each bike will be held by a strap on your downtube.

    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.
