Yeah, I live in Montreal which gets like 90 inches of snow annually and can get down to the -20s Celsius regularly in the winter. And yet I (and many others) still bike throughout the winter. Turns out having good protected bike infrastructure and plowing it regularly in the winter makes biking perfectly practical even in the middle of a cold, snowy winter.
In fact, two of the best cities for biking in North America are Montreal and Minneapolis, both very cold and snowy in the winter.
