Scale back up to four whenever you need to. Swap In Seconds Dedicated 2-Bike Beam 6 Lengths 2 Angles Lifetime Warranty How It Works Remove. Transfer. Ride Light. Same modular swap principle as the four-bike pack, in reverse. Your existing components transfer across to the shorter beam, and the four-bike beam goes in storage until the next family trip. 1 Remove 4-Bike Beam Lift the four-bike main beam off the pivot base using the tool-free pivot pins. Set it aside or store on your wall mount. 2 Transfer Components Move two sets of wheel cradles and frame supports across to the two-bike beam. The remaining components stay with the four-bike beam for next time. 3 Drop In 2-Bike Beam Drop the compact two-bike beam onto the same pivot base. Lighter, shorter, and less rear overhang for everyday use. "A dedicated two-bike beam gives you a lighter, more compact carrier for weekday rides without compromising your four-bike setup for the weekends." Why A Dedicated Two-Bike Beam Lighter. Shorter. Less Overhang. Running a four-bike beam with two empty positions adds unnecessary length and weight behind your vehicle. The two-bike conversion gives you a purpose-matched carrier for smaller loads. Right-Sized For The Ride Two Bikes. Minimum Footprint. The dedicated two-bike beam is a single-piece structural member with no joints or split points in the load path. It's shorter, lighter and sits tighter to the vehicle than a four-bike beam with empty positions. Less overhang means better departure angles and easier parking in tight spaces. Shorter overall length reduces rear overhang Lighter weight for daily driving and fuel economy Single-piece beam maintains full structural strength Same pivot base, same mount, same lifetime warranty Choose Your Configuration Six Lengths. Two Angles. The two-bike beam is available in a wider range of lengths and departure angles than the four-bike, so you can precisely match your vehicle's clearance requirements.
