The scene shows a cyclist under a massive stone and metal bridge structure, typical of Parisian railway viaducts. The signage, road markings for cyclists, and the distinctive architecture of the building in the background strongly suggest Paris, France. The traffic flows on the right, which is consistent with French road regulations. The overall urban aesthetic and the specific design of the bridge support point to a location near the Seine. I am very confident this is in Paris.
