I think it's mostly about culture and infrastructure. When we lived in Southern Germany, I cycled to work literally 5 days a week for three years (22-25 km per day, depending on the route), yes also when was snowing or raining. I still use cycling as the only means of transportation to the office, but with WFH it's currently only 2-3 days per week. I live in The Netherlands again, where cycling is one of the primary forms of transportation. Rain: I use rain pants and waterproof jacket/shoes. Snow: bike lanes are cleared, though I did regularly cycle on snowy roads in Germany when they were not cleared yet. Tires with some profile and experience make it very doable.
