The last time I rode in a good hard winter (Britain normally goes from periods of tepid and changeable weather to cool and changeable weather), which is many, no, many, many, no, don't go there, years ago, I used to be on a 250 MZ going into work 10 miles through snow and ice. People blue and shuddering from the cold were asking me how I could ride a bike in those temperatures (we actually hit -10C sometimes, cold for us). Cold? I worked up a sweat kicking it straight and pulling it back out of the gutter every time the front wheel locked up.
