People in much more extreme climates bike at rates an order of magnitude higher than the US and Canada.
People physiologically adapt to the climates they live in by being outdoors.
North Americans who complain about the cold use the wind chill rather than ambient temperature when that’s not actually the temperature they’re feeling with clothes on that block the wind. They also take the coldest data points and just say “that was the whole winter”.
Poor weather magnifies the US and Canada’s unsafe bike infrastructure. If we had safe, well-maintained bike infrastructure, it would not be nearly as much of a problem (shown by the Nordic countries biking all the time in the snowy dead of winter).
Car infrastructure makes hot weather much worse by creating a heat island.
In extreme weather, you can still delay your trip, take public transit, take a car, etc. Commuting via micromobility isn’t a binary yes/no thing; if you can’t on some days, then don’t.
thank you!
