In the link I gave above I said, "..you can put a tarp down on the back floor if the tires are dirty or muddy so you aren't making a mess in the back hatch area."
But I agree, if you're really into mud bikeing you're probably better off with a rack.

 

I asked the same question above... even if it isn't lowered it looks like it sits really low to the ground and it is bound to limit your departure angle which is only about 22 degrees stock. See the second post photo as an example.

 

I've got the Hollywood brand clamps ( ) and use them in my RAV4 to carry the bike, but I found in the Fit it's a lot more difficult to get it in and out because I have a commuter bike with raised front bars. I also think it would be really hard to get two bikes in the back of a Fit that way.
For one bike the behind the front seat method really works well and you don't even have to take the wheel off.

 

Just don't try to park in your garage..

 

I put my mountain bike, and now my road bike in the back of the fit with the fork mount on a carpet covered 2x6:



Fits like a glove, and yes I've tossed other bikes in the back along with my MTB too. Normally I just put the seat behind the drivers seat down, and angle the bike so the back tire points between the drivers seat and rear door.

My mountain bike does not fit sideways if you raise the back seats up, the front end on Konas are very slack and the bike is about 1/2" too long.

I also have the Honda cargo kit that covers the seat backs and sides, wipes out really nice after riding silty trails and tossing the muddy bike back there.

 

My mountain bike gets pretty muddy as I ride riverside trails. I have the honda cargo cover in the back that covers the back seat and sides. I just let the mud dry and vacuum it out.

 

I did the same thing, it works great (see my pic in above post). Tip: if you have a MTB with flat bars, and a road bike with drop bars, the fork needs to be farther away from the rear hatch with the drop bars so they don't hit.

Just use a larger 2x6 and put the fork mount a little off center (front to back, not side to side). Not right on the edge of the board, but not in the center. The MTB flat bars will fit with the fork mount right near the back of the cargo area. Flip the board around, and now the roadie drop bars should fit.

Also, the bike should easily fit if you just drop the drivers side rear seat, and angle the rear of the bike between the drivers seat and side door. Makes the bike a lot more stable and not wanting to flip on it's side during turns - but I usually toss a bungee cord across it as well.

After you do it once or twice you can have your bike in or out of the car and the wheel on faster than putting it on or taking it off a roof or hitch rack.

 

After running fork mount roof racks with my last few cars, I decided to go a different route with the Fit.

Ended up going with a hitch and a Swagman XC2 rack. I'm excited to not have to remove wheels every time we head out - my girl's bike doesn't have a quick release for some inexplicable reason so it was always a bit of a PITA.

There are several videos on etrailer that give measurements regarding ground clearance and after viewing those I'm not super concerned about scraping. Plus I needed a hitch anyway so it made sense this time around.

Going to be putting the setup to the test with 2 bikes and a 3k+ mile road trip in June!
