I'm upgrading to a 5-bike carrier as the family is big enough now and as such, I'm selling my gently used (though it has been used on trips throughout the U.S.) Rola NV2 hitch-mount bike carrier.
This has been an extremely good hitch mount carrier and while basic in its function (with no security lock feature like some of the Yakima options out there), it's an excellent option as a budget bike rack. You can read details about it here:
Rola - Bike Carrier - NV2â„¢ - Hitch Mount
I believe they retail around $190 or so but I'm happy to let it go for $120 shipped. Again, it's in excellent condition and a great option for two bikes. Shoot me a PM if interested or post up here. Cheers!
