You can't compare a Finnish city/municipality with a German one. In Germany it's often 5-6 km to the next municipality. In Finland it's 5-6 km to the next residential area in the (few) big cities. I'd guess the coverage of bike paths in Freiburg and Oulu might be very similar. It's the cities that are not comparable. Finnish municipalities often have the size of German county (Landkreis), but not even the population of a German city. (I have lived in Germany and Finland. But have never visited Freiburg and it's decades that I biked in or even visited Oulu the last time.)
