> Not many cities can boast 27 percent of cyclists continue using their bikes several times a week all year-round, especially not in cities with eight and half months of winter or an average of 256 days of thermal winter and snow. Oulu, Finland (population 191.000), however, is no ordinary town. It is a town where 98 percent of the cycling network is maintained all winter and all routes have street lighting.

With the right infrastructure and services, snow is no obstacle.
