The bike path markings and the general landscape, including the canal and bridge structure, strongly suggest a European setting, likely in a country like Germany or Poland. The overcast sky and deciduous trees indicate a temperate climate. The signage style and the bridge architecture are consistent with Central European infrastructure. I suspect this is near a river or canal in a mid-sized town. I am moderately sure this is in Germany.

The graffiti style and the specific design of the concrete underpass are very characteristic of urban areas in Germany. The blue circular sign visible in the distance is a standard German traffic sign for a mandatory path for pedestrians and cyclists. The overall infrastructure and vegetation align perfectly with a suburban or park-like area in a German city. I am fairly confident this is in Germany, likely in a city like Berlin or Hamburg.
