The probability of biking in winter is associated with increased access to on-street cycling facilities such as bike lanes and cycle tracks near the shortest route of travel.
Women, compared to men, were less likely to bike in all seasons.
Winter bicycle traffic is just over one fifth summertime levels. Toronto is a “moderate” winter city, along with Calgary and Minneapolis. These cities experience January highs close to 0°C (-1°C in Toronto) and lows close to -10°C (-6°C in Toronto). Temperature extremes are rare.
