SUPER73 x 1UP USA Super Duty Fat Tire Bike Rack Add-On Tray

Modular Expansion for Growing Custom Lineups

Don’t buy an entirely new car carrier just because you added another bike to your fleet. The official SUPER73 x 1UP USA Super Duty Add-On Tray is the definitive modular solution engineered specifically to bolsters your transport capabilities. It integrates smoothly onto the back of your primary Super Duty or Xtreme Duty base unit, creating an angled step-up configuration that maintains excellent ground clearance when driving up steep driveways or technical off-road trail heads.

Smooth One-Handed Ratchet Operation

Loading up a heavy electric bike shouldn’t require a wrestling match. This premium add-on tray features 1UP USA’s advanced one-handed press-and-lift mechanism. A smooth, intuitive release lever lets you disengage the ratcheting system and open the dual oversized bent arms with one hand, leaving your other hand completely free to steady the bike. Once the tires are seated in the tray, simply push the pivot arms down—an audible, tactile click confirms that the mechanical system is securely locked around the tire tread.

100% Paint Protection and Total Stability

Just like the base station, this modular tray uses frame-free contact technology. The dual-bent structural arms isolate clamping force strictly to the rubber tires, ensuring that your bike’s custom powder coat, internal brake lines, and delicate suspension forks are completely protected from frame-rub and strap friction. When empty, the arms fold entirely flat, minimizing your vehicle’s rear profile and ensuring unhindered compatibility with loading accessories like the V-Style Ramp.

PRO-TOOL KIT & CHECKOUT ARCHITECTURE

⚠️ Storefront Notice – Safety & Security Check: The Super Duty Add-On tray ships with specific high-tensile security connecting bolts. Advise your customers to use only the official 1UP USA security assembly hardware included in the box. Substituting standard local hardware store bolts can compromise structural joint strength under heavy highway wind loads.

🛠️ Essential Checkout Cross-Sells & Configuration Tips

1. The Base Rack Prerequisite Check: Add an mandatory checkout prompt or clear bold warning on the listing: “Requires a 1UP USA Super Duty or Xtreme Duty Base Platform Rack for installation. This item is a modular extension tray and cannot connect directly to a vehicle hitch receiver on its own.”

2. 1UP USA Wheel Chock Upgrade: Highly recommended as an add-on item for buyers carrying long-wheelbase or front-heavy bikes (like the R-Series) on the outer tray, as it dramatically suppresses steer-tube rotation over uneven asphalt.

3. 1UP USA Add-On Lock Kit: Provide a secondary checkout checkbox for specialized lock pins designed specifically to secure the add-on tray frames directly to the base platform, providing robust anti-theft security for the hardware itself.
