It's not the most versatile hitch type, but plenty sturdy and cheap enough for occasional use. If you're hauling bikes a lot, for long distances over crappy roads, want to best protect your bike's finish, hauling very expensive bikes...spend the big money and buy a high quality rack.
Consider a wheel-support or platform type, maybe.
