Well, in such a case, I don't think I'll have a job to commute to.
I assume that you are talking about something more serious than a bad snowfall. Most bikes I have are really solid enough that beyond lubrication and flats, they could probably go for a year or more. If you are proposing a situation where parts are completely unavailable for over a year. I think you will have far bigger problems than that.
