FYI, Curt makes a front receiver hitch for Ford pickups. They're carried by a number of vendors, such as eTrailer and sell for about $160. They're quite easy to install but may require some air dam mods. I have one on my 2012 F-150 EcoBoost originally put there in the event that I have the park my TT in a very tight spot. Using it for a bike rack is a great idea!
Thanks, Brian, for the info. After serious consideration of the Hitch Hooks option, I finally decided go with the Curt front receiver hitch for the Ford Expedition as I should be able to mount a bike rack to it without having to do any modifications. $162 from eTrailer with free shipping. Plan to install it myself--may have to cut a notch out of the lower fascia, which has me a little anxious. Otherwise, the installation looks to be pretty simple--just four bolts. We'll see...
