In photography (and probably art in general), there's a composition "rule" to frame moving subjects from left to right.

So the direction may not be that interesting!

The other thing to consider (as someone who frequently take a photos of their bike) the common direction has the drive side out! In cycling forums it is sacrilegious to post a photo of your bicycle without showing the drive side.

I wonder if that changes in countries where the main language is written right to left?

That was my first thought too, I wonder if it works the same in countries speaking arabic (as that's the first one i could think of that's a language with truly no-buts right to left writing).

Arabic native speaker here.

Yes, people will usually post or draw a bicycle right to left which is going to ve opposite of what normally is drawn. I tried the prompt in arabic for many models and I don't recall any adjusting it based on that difference at least culturally speaking.

Is it culture dependent? Is it because in English we read left to right?

There was a glorious moment when I thought that the Chinese models were more likely to produce right-to-left cycling pelicans, but sadly that trend didn't seem to hold up.

For almost the last 70 years, Chinese has been left to right.

Before that it was vertical (although the ordering of the columns was right to left).

Arabic or Hebrew would be better tests for that.

Chinese is also written left to right
