This bike rack is great! Lifetime warranty and a competitive price! Lock for the hitch and the bikes included!! Great for in town or trail, and very easy to use and install. With no wiggles or wobbles, it will fold up flat against the back of the vehicle when not in use. Not suitable for carbon fiber frames. Don't pay any attention tot he 1-star reviews, those people clearly weren't using the rack properly which is a shame, because, it is so easy, they ust want someone to blame!
