The bike in the photo is on grass because it was in a campground but his trip was all on paved roads. I call that bike packing even though it was not off road. But life is too short to argue about such things, if you do not agree, I am not going to waste time arguing about it.
It was a nice bike, it was a Break Away frame, he did not pay oversize fee to the airline for this trip. And he was packed so light, he might have gotten the rest of his stuff into a carryon instead of a second checked bag.
I am always amazed when people pack that light for a trip longer than a few days. If I recall correctly, he and his girlfriend were doing a two week trip and were packed that light. But, they were on roads so they they did not have to carry a week of food on the bike or anything like that.
No he was not doing his whole trip with one water bottle, he lost one.
