Kuat Piston Pro X 2-Bike

This is everything the Piston Pro offers plus a higher 134 lb total capacity and wider wheelbase compatibility up to 53 inches. Both bike and hitch locks are integrated, it folds flat against your vehicle, and the zero-frame-contact design is safe for carbon. At 63 lbs it is actually lighter than the standard Piston Pro. If you have heavy e-bikes or long-wheelbase bikes, this is the version to get — it handles the edge cases the standard model does not.
