The first and third shots in your post are the ones I’d crop a bit tighter. In the first frame, trimming some of the side clutter would push the rider’s face and handlebars forward; in the third, a slightly tighter crop would make the rider and strapped load dominate more cleanly instead of sharing attention with the busy edges. That’s basically the standard street-photo move: tighten when the background starts competing with the subject, especially in crowded scenes, which lines up with general composition advice from Fstoppers and this piece on creative cropping.
