I currently own three different types of hitch mounted racks.
All three that I currently own carry the bike on a tray vice holding the bike via the top tube. I had a rack like that once. Not any more. I have too much time, cash and emotional investment into my bikes to subject them to a hanging style rack these days.
I don't carry bikes on the front, though I do have a front hitch. On the TC, I have one of these:
1st true swing away tray style rear rack
But, it can only carry two bikes. I've tried to use it to carry 3. 2 is all I trust it for. I'm using trays from a Thule T2, which is this one:
Thule T2Now, I have this one:
MWE Bladerunner It can take virtually any style of hitch mounted rack and turn it into a swing away rack. I'll be using my original Thule T2 with 2 bike add on kit (for 4 bikes total).
For my car, I have one of these:
The EASIEST to use hitch mounted rack you can findMade of aluminum, modular, and a total breeze to use. No lock either to keep it in the hitch...you need a special (it is pretty darn special) allen wrench to remove the rack from the hitch. Because my car has the 1.25" receiver, I can only carry two bikes with the base that I have on this one. Otherwise, the rack would go onto the MWE blade runner above for the lightest weight and easiest to use swing away 4 bike tray style hitch mounted bike rack one can find.
