I have a low profile, hidden hitch. Barely visible 1-1/4" black square, under the bumper.
And this Thule rack is the best I've ever owned. Comes on or off in seconds.
Now when my wife and I take our bikes to local national parks and abroad, we don't have to take her truck.
The rack is an Apex 4 Bike. I got it for 25% off at REI. They have a Thule sale several times a year.

Here you can see that the hitch is almost undetectable.
I bought the hitch from and had it installed at a professional trailer/hitch place near me. About $230 out the door. Took them about an hour. This is the hitch:
