We have the Thule Helium rack on our Fit and really like it. I ordered the hitch on line, and had it installed at the U-Haul dealer for about $50 bucks, as we are not handy people.

With the seats down, I could probably put my bike in the back of the Fit standing upright, but my husband's bike is too tall. I can definitely put it in laying flat without taking off wheels (a nice plus, since I hate having to take off the wheels).
