My mom puts on her winter tyres and drives her bike to work through the winter, in Finland. She's almost 60. A few of my coworkers do as well. It doesn't quite get to -35c, but -20 isn't uncommon and it's below freezing for two to three months. I'm not quite as tough, I ride to work the 9 months when there's no ice on the roads. I might try winter cycling but O don't have the equipment yet (mostly clothes but tyres etc too).
