6 years ago we had a moving company move us about 500 miles. We had 7 bikes.
I stuck the 2 most fragile/valuable ones on the back of my car and just let the movers deal with the bikes as they saw fit. The just laid them on top of everything else, and wrapped in blankets where needed. They came out fine other than one brake lever that got damaged because the cable was too short and at some point the bars got turned too far. That was my own fault, really. I should have disconnected that cable from the lever…. or better yet, replaced the cable with a longer one when I went with wider and taller bars on that bike.
Anyway, a new v-brake lever was way less time and money than packing up 5 bikes in boxes.
