I shipped my bike to Maine for a repaint. The LBS dismantled it for me, small fee, and boxed it. I ran it down to UPS and shipped it. The LBS would have shipped it but the UPS had already picked up that day. BTW, I did insure the frame for the current value.

Some of the bike shops around here rent boxes.

My bike fits inside my Honda CRV. No worries about it getting damaged on the outside of the vehicle.
