I began snow biking on Saturday, January 5. We have a good three feet of snow in Montreal. Commuting has its challenges including slush, hidden ice, hard ice chunks, over-heating, and less room on the road.
Zip ties did not work well. They may have added a little bit of traction, but all but 2 broke off today while riding.
I depend on less-used back roads that are still used enough to have tire marks down to the pavement to bike on. When I don't have that option, I bike on sidewalks or walk my bike.
I suit up in snow boots, wind pants, winter jacket, manly leather mittens, hat, ski goggles, and my helmet.
In non-snow conditions, it takes 20-25 minutes to bike to school. Now it takes 35.
It is also much harder to bike through snow, however, I still enjoy it! Part of the difficulty stems from Christmas cookies and having a month off from biking.
