The Raxter line of platform mount bike racks is one designed with the basic belief that simple is good. Starting with a basic design that uses welded components, Velcro Straps and only a few moving parts, each Raxter design is truly intuitive and offers a simple and strong design that redefines the phrase ‘bullet-proof’.
Auto-Nesting Feature
This patented feature gives the Raxter hitch mount bike racks the ability for the bikes to shift forward and rearward of each other, eliminating the entanglement and damage that occurs with other designs.
Over $800 new
Comes with some spares and 2 keys and hitch lock.
This rack is on the heavier side but is strong as an ox and can carry a big payload.
You can also buy accessories to fit fat bike and wider e bike tires.

I sad to let this go but it's the end of an era and I rarely carry 4 bikes anymore and so also have another adaptable 3 bike rack.
