How did it go with your crossbars and mounting two bikes?Two mountain bikes and three 29" wheels are the limit for the trunk. Forget about putting anything else into the trunk except Tetris style slip through items between pedals. Only other place for the 4th tire would be the back seat area.
I imagine some would chalk that up to a win, but it did not feel that way...
Gritted my teeth and bought the crossbars and 2 bike mounts so that my wife can actually put things and children into the car for the next trip. $1200 well spent I hope.
