Plenty of people in Oulu, Finland bike literally all year round. Fully 12% of all trips in winter are made by bike.
Their secret? Just as the roads are plowed, so are the bike paths. If we didn’t plow and salt the roads up north, cars would also seem ridiculously impractical compared to a snowmobile or cross country skis.
Oulu invests in making winter biking safe and practical, while American cities of comparable size and climate like Syracuse, NY don’t. The results are predictable.
