The Thule Fatbike Rail in straight black is a replacement rail designed to transport one fat bike or e-bike with oversized tyres on Thule Elite Van XT and Thule WanderWay rear-mounted bike racks. This extra-long rail measures 1.40 metres and accommodates tyre widths between 3 and 5 inches, making it suitable for modern fat bikes and electric bikes with wider tyres. The rail slides from left to right for optimal bike positioning, and the extra-long straps with pump buckle tensioning system secure the wheels firmly during travel.

The straight black fat bike rail is compatible with two specific Thule rear door racks: the Thule Elite Van XT and the Thule WanderWay. These racks mount to the rear doors of campervans and motorhomes, particularly Fiat Ducato, Citroen Relay, Peugeot Boxer, Mercedes Sprinter, and VW Crafter models from 2006 onwards. The rail supports a maximum load of 30kg.

Installation is straightforward and requires no drilling or permanent modifications to your existing Thule rack. The rail's adjustable positioning system means you can slide it horizontally to create the right spacing for your bike's frame geometry. The pump buckle tensioning on the straps provides secure clamping without damaging your wheels, and the matte black powder-coated finish matches the aesthetic of most Thule rack systems whilst providing weather resistance.

If you're running standard tyres, you won't need this rail, but for anyone with fat bikes, plus-sized mountain bikes, or many e-bikes with 3-inch or wider tyres, this is the component that makes rear door transportation possible. The 1.40-metre length gives you enough rail to position the bike securely without overhanging the rack, and because it's a straight design rather than curved, it suits a wider range of bike frame types and wheel positions.

Frequently Asked Questions

Will the Thule straight fat bike rail fit curved frame Thule racks like the Elite G2?
No, the straight black fat bike rail is designed specifically for the Thule Elite Van XT and Thule WanderWay racks only. If you have a Thule Elite G2 or Thule Excellent rack, you need the curved anodised fat bike rail (product code 302058) instead. The straight and curved rails are not interchangeable because they have different mounting brackets and frame geometries to match their respective rack designs.
How do I know if my bike tyres are too wide for a standard Thule rail?
Check the tyre sidewall for the width measurement, which is typically shown in inches. Standard Thule bike rails accommodate tyres up to 2.5 inches wide. If your tyres measure 3 inches or wider, you need the fat bike rail. Most fat bikes, many electric mountain bikes, and plus-sized mountain bikes have tyres between 3 and 5 inches wide. Common sizes that require this rail include 3.0, 3.8, 4.0, 4.5, and 5.0 inch tyres.
Does the 30kg weight limit apply to the bike or the rack?
The 30kg maximum load applies to the individual fat bike rail itself. The Thule Elite Van XT has a total rack capacity of 35kg across both rails, with each standard rail rated to 19kg. When using one fat bike rail and one standard rail, keep your fat bike under 30kg and your standard bike under 19kg. Most fat bikes weigh between 13-18kg, and electric fat bikes typically weigh 20-28kg, so the 30kg limit accommodates most bikes in this category.
Can I fit two fat bike rails to my Thule Elite Van XT to carry two fat bikes?
Yes, you can purchase two fat bike rails and fit both to your Thule Elite Van XT or WanderWay rack to transport two fat bikes simultaneously. Each rail is sold separately and replaces the standard bike rail. Make sure the combined weight of both bikes does not exceed the rack's 35kg total weight capacity. The 20cm spacing between rails on the Elite Van XT provides sufficient clearance for two fat bikes with wide tyres.
Do I need any tools to install the fat bike rail on my existing Thule rack?
Installation requires no drilling or permanent modifications, but you may need basic tools like a screwdriver or Allen key to remove the existing standard rail and attach the fat bike rail to the mounting brackets on your Thule Elite Van XT or WanderWay. The rail simply replaces your existing rail using the same mounting points. The pump buckle straps are tool-free and operated by hand for wheel tensioning.
