I unpacked quite a few in the early 80s. Puchs came over from Austria in a box like a 60" flatscreen TV box, but 16" wide. Pedals, seat, handlebar, front wheel were off and packed along side the ped with foam sheets or cardboard in between them. All Cables were mounted to the handlebars, ready to go. Perhaps get two identical 60" flatscreen boxes and make one box, extra wide one?
