The moment a thru axle fork mount does not match your axle size, you find out in a parking lot with the front wheel already off and the bike balanced on one hand. Thru axle standards vary more than quick release ever did, and a mount that fits a 15x110mm boost fork will not accept a 12x100mm road axle without the right adapter. The bolt pattern matters too, because a mount drilled for M8 T-nuts will not drop into a truck bed track built for 5.8mm hardware.
I looked at the Best Bike Cargo Racks For Thru Axle and focused on the details that decide whether a mount actually works: which axle sizes ship in the box, whether adapters are included or sold separately, how much clearance the base leaves for brake calipers, and whether the hardware matches common truck bed and van track systems. A fork mount is a simple piece of metal, so the differences come down to fit and finish rather than features.
My overall pick for best bike cargo racks for thru axle is the MUQZI Quick Release Fork Mount. It ships with four pairs of adapters covering 12x100mm, 15x100mm, 15x110mm, and quick release 9x100mm, so one mount handles most of the bikes in a household. My top picks are just below.

Detailed Review
The MUQZI Quick Release Fork Mount is a 0.35-pound aluminum alloy block that holds a bike fork in a truck bed, van, trailer, or roof rack. Its heightened design lets the quick release lever rotate without scraping the mount surface, which matters when you are tightening a skewer in a tight bed space.
Four pairs of adapters cover M12x100mm, M15x100mm, M15x110mm thru axles and 9x100mm quick release, so one mount can move between a road bike, gravel bike, and MTB. The fixed rubber rings keep adapters from dropping into gravel while you install the mount.
Worth knowing before you buy: the included M8 screws and 5.8mm and 8.2mm T-nuts may not fit every rack channel, so check your bolt size first. I'd consider this for a rider hauling one bike who wants a compact, adaptable fork block.
A solid metal thru-axle fork mount that holds one bike up to 48 lbs with a flip-top quick-release mechanism.
Key Facts
- Item Weight
- 1.1 lbs
- Axle Compatibility
- 12mm and 15mm thru axle
- Material
- Solid metal with TPV plastic shim
- Included
- Spare TPV shim and track hardware
Pros
- +Flip-top mechanism simplifies loading without pulling the axle sideways
- +TPV shim fits both 12mm and 15mm axles without changing parts
- +8cm clearance protects most disc brake calipers from floor contact
- +Spare shim and track hardware included for setup
Cons
- −QR hub adapter for quick-release bikes sold separately
- −Weighs 1.1 lbs, heavier than minimalist fork mounts
- −No warranty term stated in the listing
Detailed Review
The ODIER fork mount uses a TPV plastic injection shim that grips both 12mm and 15mm thru axles without needing a different insert. That matters if you swap between bikes or travel with a buddy whose axle standard differs. The flip-top opening lets you drop the fork in vertically rather than threading the axle from the side, which saves space inside a van or camper where every inch counts.
I see the 8cm clearance from base to axle center as the detail that keeps most disc brake calipers and fork adjustment knobs off the floor. The mount carries one bike up to 48 lbs, so it suits a trail or enduro rig without feeling overloaded. The T-bolt adjusts by spinning for a tighter hold, and a spare shim plus track hardware come in the box.
Worth knowing before you buy: quick-release bikes need a separate QR hub adapter, and the 1.1 lb metal body is heavier than some plastic alternatives. I'd consider this a reasonable pick for van lifers and camper owners who want a stable, bolt-on fork mount.
The Kuat Dirtbag is a 1 lb steel bolt-on bike rack for one bike with a 15mm x 110mm thru-axle, designed for truck beds, trailers, and garage storage.
Key Facts
- Item Weight
- 1 lb
- Axle Size
- 15mm x 110mm
- Material
- Steel
- Dimensions
- 7 x 7 x 3 in
Pros
- +Steel construction with a resistant finish for regular outdoor use
- +Bolts to nearly any flat surface for flexible storage or transport
- +Compact 7 x 7 x 3 inch size stores easily when not in use
- +Single thru-axle mount holds one bike without a wheel tray
Cons
- −Hardware for the two-bolt install is not included
- −Fits only 15mm x 110mm thru-axle forks, not quick-release or other sizes
- −Requires removing the front wheel before each use
Detailed Review
The Kuat Dirtbag is a 1 lb steel mount that bolts to a flat surface and holds one bike by its 15mm x 110mm thru-axle after you pull the front wheel. That format suits a truck bed, a trailer deck, or a garage wall where a traditional wheel-tray rack will not fit.
Installation is two bolts, though hardware is not included, so you supply your own fasteners for the surface you choose. The 7 x 7 x 3 inch body stays out of the way when the bike is off the mount, which I rate as a real advantage in a packed van or small shed.
The main trade-off is fit: this version only accepts 15mm x 110mm thru-axles, so quick-release forks and other axle standards need a different Dirtbag. I see it working best for riders who already run that axle and want a low-profile, permanent mounting point.
Snap Fork is a CNC-machined 6061 aluminum thru-axle fork mount with a 45mm axle height and adjustable knob fitting 12x100, 15x100, and 15x110mm axles.
Key Facts
- Item Weight
- 0.44 lbs
- Axle Height
- 45 mm
- Material
- 6061 Aluminum
- Compatible Axles
- 12x100mm, 15x100mm, 15x110mm
Pros
- +45mm axle height sits 20mm lower than most fork mounts
- +CNC-machined 6061 aluminum body with stainless steel hardware
- +Adjustable knob fits three thru-axle sizes without adapters
- +Drop-top design mounts from above in tight spaces
Cons
- −Thru-axle must be pre-installed before dropping fork in
- −No mounting hardware or track system included
- −Axle height may not clear some cargo box lids
Detailed Review
The Snap Fork mount stands out for its 45mm axle height, which sits 20mm lower than most fork mounts. That matters when I'm stacking bikes in a minivan or truck bed, because every millimeter of vertical clearance counts. The CNC-machined 6061 aluminum body and stainless steel hardware suggest it will hold up to repeated loading, though I can't speak to long-term corrosion resistance beyond the listed materials.
Installation is genuinely quick: flip open the cap, drop in a thru-axle fork that already has its axle installed, close the lid, and tighten the knob. The adjustable knob covers 12x100mm, 15x100mm, and 15x110mm axles without adapters, so one mount works across a mixed quiver of bikes. I rate this a reasonable pick for anyone hauling multiple bikes who wants to skip the usual skewer threading and alignment fuss.
Worth knowing before you buy: the thru-axle must be pre-installed in the fork, and no mounting hardware or track system comes in the box. For my money, this suits riders who already have a rack track or flat surface to bolt it to.
The MUQZI Bike Fork Mount is an aluminum alloy thru-axle block with four adapter pairs for M12x100, M15x100, M15x110, and 9x100mm quick-release forks.
Key Facts
- Item Weight
- 0.35 lbs
- Material
- Aluminum Alloy
- Compatibility
- M12x100, M15x100, M15x110, 9x100mm
- Included
- Fork Mount, QR Bar, 4 Adapter Pairs, Screws, T-Nuts, Rubber Rings
Pros
- +Aluminum alloy construction with CNC machining for solid fork support
- +Four adapter pairs cover common thru-axle and quick-release standards
- +Heightened block clears quick-release lever during installation
- +Rubber rings on adapters stay fixed after mounting
Cons
- −Mounting bolts may not fit all truck bed or roof rack tracks
- −No locking mechanism to secure bike during transport
- −Fork mount only, no wheel tray or rear wheel strap included
Detailed Review
The MUQZI Bike Fork Mount is a 0.35 lb aluminum alloy block with a heightened profile that lets the quick-release lever rotate without scraping the mounting surface. It comes with four pairs of adapters, covering M12x100mm, M15x100mm, M15x110mm thru axles and 9x100mm quick-release forks, so one block can serve several bikes in a garage or shuttle rotation.
For truck bed or van transport, the included M8 screws and 5.8mm or 8.2mm T-nuts fit some rail systems, but I'd measure your existing track before ordering because the listing warns that mounting bolts may not suit every rack. The fixed rubber rings on the adapters are a small but useful detail, keeping them from dropping off during installation.
The main trade-off is that this is a fork-holding block only, with no wheel tray, rear strap, or locking feature. I see it working best for a simple two-bolt setup in a pickup bed or on a trailer, where the bike's rear wheel can rest on the bed floor.
The ODIER Bike Fork Thru Axle Adapter converts a QR fork mount to thru axle, available in four sizes including 12x100mm, and weighs about 0.45 pounds.
Key Facts
- Item Weight
- 0.4519476371 pounds
- Size
- 12 x 100mm
- Compatible Mounts
- Thule, Yakima, Rocky Mounts, Seasucker, Parktool
- Included
- 1 adapter
Pros
- +Four thru axle sizes cover most modern mountain and road bikes
- +Welded one-piece metal feet resist bending at the rack interface
- +Circular groove on skewer center limits loosening on rough roads
- +Compatible with Thule, Yakima, Rocky Mounts, Seasucker, and Parktool
Cons
- −Single adapter only, so two bikes need two separate purchases
- −No locking mechanism to secure the bike to the rack
Detailed Review
ODIER's thru axle adapter solves a specific mismatch: a QR fork mount block that will not accept a modern thru axle. It comes in four sizes (15x110mm, 15x100mm, 12x100mm, 20x110mm), and the 12x100mm version weighs about 0.45 pounds. The circular groove around the skewer center is meant to limit loosening on bumpy roads, a real concern on washboard gravel or long highway drives.
The feet are one piece of metal with a large welding area, which I see as an attempt to keep the feet perpendicular to the tube and resist damage when the bike is loaded and unloaded repeatedly. Compatibility is broad: Thule, Yakima, Rocky Mounts, Seasucker, and Parktool repair stands are all named.
Worth knowing before you buy: this is a single adapter, so carrying two thru axle bikes means buying two. There is also no lock, so the bike is only as secure as the rack itself. I'd consider this a practical fix for anyone with a thru axle bike and an older QR rack mount.
FAQs
How do I know which thru axle size my fork mount needs?
Check the axle diameter and spacing printed on your fork or axle, because a 15x110mm boost fork will not fit a mount built only for 12x100mm. Most mounts list their supported sizes in the product details, and the MUQZI and Snap Fork models cover the common combinations without extra parts. Measure before ordering rather than guessing from the bike model.
Can you mount a thru axle fork mount on a car roof rack?
Yes, several fork mounts bolt to roof rack tracks as well as truck beds and van floors, provided the bolt spacing and hardware match your track. The MUQZI mount includes both M8 screws and smaller T-nuts to cover common track sizes. Check your rack’s bolt dimensions first, since a mount with the wrong hardware will not sit flush.
Is it better to use a fork mount or a hitch rack for transport?
A fork mount suits vans, truck beds, and trailers where you want the bike low and out of the wind, while a hitch rack keeps the wheels on and is faster for frequent stops. Fork mounts take more setup because the front wheel comes off. For long highway drives, the lower profile of a fork mount reduces drag and keeps the bike stable.
Do fork mounts work with disc brake forks?
Clearance between the base and the axle center is what keeps a disc brake caliper off the mounting surface, and the ODIER flip top leaves about 8cm of space for most forks. Low-profile mounts sit closer to the base, so check that your caliper and fork adjuster clear the floor. Measure your fork’s caliper position if you run larger rotors.
Final Thoughts
The deciding factor in this category is axle compatibility, followed by whether the mounting hardware matches your truck bed, van floor, or roof track. A mount that fits your axle but not your track is no more useful than one that fits neither, so match both before you buy.
The MUQZI Quick Release Fork Mount is my pick for anyone hauling a mix of bikes, because the included adapters cover 12x100mm, 15x100mm, 15x110mm, and quick release forks in one unit. The aluminum body and raised lever design keep the release bar clear of the mounting surface, which matters when you are tightening it down in a truck bed. Riders who only ever carry one axle size can save a few dollars with a simpler mount, and anyone needing a 20x110mm axle should look at the ODIER adapter instead. If you want a mount that handles most of the bikes in your garage, check the current price on Amazon and confirm your axle size before ordering.
