I installed the class 1 Curt hitch custom designed to bolt on the Eos frame and installed an isolated 4 wire trailer wiring connector. I use them both to pull a small 2 wheel motorcycle trailer or I can use the hitch itself for a trailer hitch ball bike rack I already owned. Works good. The only down side to the Curt hitch is that lowers the rear ground clearance of the Eos by a couple of inches. It mounts below the lower bumper cover vs. the Euro hitch that uses a different bumper cover with a hitch cutout so no ground clearance is lost. So far no scrapes on the bottom of the hitch receiver.
It has a pivot point held in place by a cotter pin so it can be quickly folded down horizontal to the ground, this gets it out of the way so I can lower the top without removing the bike rack. It is a standard type of bike rack, the fold down feature allowed me to open the rear hatch on my other ride, a Ford Escape, with the bike rack mounted.
The down side is that I have to take great care not to operate the top with the bike rack installed before remembering to fold the rack down.
