How do you folks transport your two wheels in your four wheels? I'm currently in posession of two bikes, a road bike and an MTB. I will soon need to drag them on journeys of around 20 miles or so. In the short term I won't stick anything on my car and in the long term I'd rather not do anything to my car.
Does anyone just take the front wheel off and let it stick out the boot? I'm sure dirt becomes a big issue too.
