The rolling Bike Rack Floor Stand works with any VelociRAX hitch rack size. With this system, you can roll your VelociRAX to and from your car with ease. To relocate a VelociRAX from a vehicle, remove the hitch rack from the hitch receiver, place it in the stand’s hitch receiver, secure the hitch pin in the stand pinhole, then roll away! Once the bike rack is secure on the rolling stand, you can roll it over to the garage mount or store bikes in the VelociRAX hitch rack while secured in the floor stand. For long term storage on the floor stand or with bikes on the VelociRAX, secure the VelociRAX hitch rack completely by tightening the anti-rattle system for best results.
Your VelociRAX will feel as light as a feather, even with a fully loaded rack. Casters move freely for optimal maneuverability but can also be locked in place for stationary use. Completely stop wheel motion by pushing down on the tab of each caster. 
Intended for upright (unhinged) hitch rack use. However, as an added bonus, lowering the hitch rack using the middle stop pin position will allow for even easier bike loading and unloading for small and medium frame bikes.
