Step 01 — Setup

What's on your drawbar?

Tell us what's currently on your caravan drawbar so we can engineer the right configuration. Each setup determines how we calculate the carrier height.

Please select a scenario to continue.
Have a photo of your drawbar? You'll be able to upload up to 3 photos at the end of the configuration. This helps our sales engineers verify your setup before manufacturing — completely optional but strongly encouraged.
Step 02 — Vehicle

Your tow vehicle

We use this to select the correct carrier length for your setup. Start typing to find your vehicle.

How many bikes?

This determines the carrier angle. Two bikes use a 40° rack with standard departure clearance, four bikes use a 25° rack for a low-profile setup.

Please choose a carrier configuration.
Step 04 — Wheel Sizes

Wheel size options

Standard cradles fit 26"–29" wheels. If any of your bikes have smaller wheels (16"–24"), add a reducer pair for that position.
