The Thule Low Rider Fork Mount is a heavy-duty, ultra-versatile bike block designed to create custom transport solutions on flat surfaces like ute trays, van interiors, or custom trailers.
The Thule Low Rider Fork Mount (Model 821) is the ultimate solution for riders, tradies, and road-trippers who want to build a completely custom, rock-solid bike transportation setup. Engineered with simplicity and security in mind, this compact block allows you to convert almost any flat, solid surface into a dedicated bike carrier. Whether you are bolting it directly to the timber liner of a work van, mounting it onto an aluminium ute tray, or fixing it to a custom-built camper trailer, the Low Rider ensures your bike stays anchored through the roughest corrugated outback roads.
Crafted with a heavy-duty, premium metal construction, the Low Rider is engineered to resist warping, flexing, and weathering under the harsh Australian sun. It features a built-in 9mm quick-release fork mount skewer that clamps down tight on standard open-dropout front forks, providing a completely stable hold with absolutely zero frame contact—making it a perfect choice for protecting delicate carbon road frames and high-end mountain bikes alike. Furthermore, the skewer is fully lockable and compatible with Thule’s One-Key System, giving you peace of mind when leaving your vehicle unattended at a service station or trailhead café.
Universal Surface Mount: Can be easily bolted down to virtually any flat, solid surface to create a custom internal or external bike carrying layout.
Zero Frame Contact: Secures the bike solely via the front fork dropouts, completely eliminating the risk of cosmetic scratches or structural damage to your frame.
Heavy-Duty Metal Build: Rugged, premium construction designed to handle the vibrations of rough open roads and resist long-term wear and tear.
Lockable 9mm Skewer: Features a lockable quick-release skewer mechanism to prevent opportune theft and ensure stable transport.
One-Key System Compatible: Easily integrates into an existing Thule key setup, allowing you to use a single key across all your Thule racks and accessories.
Disc Brake Clearance: Intelligent, low-profile block geometry provides ample clearance for modern disc brake calipers without interference.

Own a Ute or Van: Perfect if you want to make full use of your vehicle's cargo space or ute tray by mounting your bikes upright and securely inside or out.
Ride Carbon-Framed Bikes: Ideal for riders who refuse to use traditional clamp-style racks that squeeze or rub against fragile carbon-fibre frame tubes.
Love DIY Custom Setups: Excellent if you enjoy tailoring your own rig, allowing you to position multiple blocks at staggered angles to maximize packing efficiency.
Want Top-Tier Security: Great if you value peace of mind; adding a Thule lock cylinder ensures your bike cannot be easily unclipped and stolen.
Need a Low-Profile Solution: A fantastic option if you want to keep your bikes out of the wind stream behind your cab, saving on fuel or battery range compared to roof racks.
Run Modern Thru-Axle Forks: Built exclusively for traditional 9mm quick-release dropouts; if your bike uses 12mm or 15mm thru-axles, you will need to buy separate axle adapters.
Want a Tool-Free Vehicle Fitment: This is a permanent or semi-permanent DIY hardware block; it does not clip onto standard roof crossbars or towballs without custom modification.
Hate Removing the Front Wheel: Requires you to detach your front wheel every single time you load the bike, which can be tedious on quick, multi-stop trips.
When planning your DIY installation on a ute tray or timber van floor, don't just align the mounts in a straight, parallel line. If you are fitting multiple bikes side-by-side, stagger the Low Rider blocks forward and backward by about 15 to 20cm, or elevate every second block on a small spacer block. This clever configuration prevents your handlebars from overlapping and smashing into each other, allowing you to pack twice as many bikes into the exact same footprint with zero trail damage!
