This may give you a few ideas for next time.

I bought my road bike on Amazon about six years ago. Bike is a Raleigh Grand Prix, that specific Grand Prix has a Ritchey Break Away frame which is why I bought it. I took a few photos of it immediately after I pulled it out of the box, but before I did anything else just to have a record of how the factory packed the bike in the box.



Photo below, saddle on seatpost is not attached to bike, it was loose in the box.



Next photo is cropped from one of the above photos. I wanted a closeup of how the rear derailleur was setup for shipping, there was an extra long plastic spacer on the skewer to hold the derailleur away from the side of the box. And chain on biggest sprocket, probably to have the derailleur as inward as possible. I would have been inclined to remove the rear derailleur, but this bike has a steel frame, hanger is not a sacrificial one that can break.



No skewer on the front wheel, small parts like that were in a separate small box.

Side note: As I was finishing my bike tour in Iceland eight years ago, at the campground in Reykjavik there were two Italians asking around if anyone knew where you could buy a front skewer for a bike, both of their front skewers were bent from the airline shipping their bikes the way they were packed. I did not know where any bike shops were, or if they would be open on a Sunday.

The aluminum canoe in the photos was not included with the bike. I bought that before Amazon existed.
