When we moved 7 years ago, we had 9-10 bikes for the 2 of us. Two went to my son a few years later, and one was my younger son's bike that he eventually took. I took 4 of them on the bike rack at a time (we moved 9 miles). I also took all of our clothes and breakable items I did not want going in the truck.
We only have 4 bikes now.
