Your preference for bicycle racks/carriers?

[ljnlaw]

I am in the market for a bicycle rack/carrier for my E53 X5. Should I go with a roof rack mount, a trailer hitch mount or a rear tailgate mount? I want to carry up to 4 bicycles at a time for the family when we go on short trips. My X is lowered and even still I am only 5'9" and it seems it may be tough to get the bikes up and down off of a roof rack system which I seem to prefer.

Does anyone currently run a rack that hangs off of the rear tailgate? Trailer hitch may be tough for me I have a back-up camera mounted in the removable plate where the traler hitch would go in the rear valence of my X. What make and models do you recommend (Yakima, Thule, etc.)? Any thoughts are greatly appreciated.
