Excellent post, but there's another rarely mentioned factor, and that's how the body reacts to *impending danger*. You naturally tense up, for damn good reason, you could go flying into concrete or asphalt just by using a bit too much lean when turning, so the body does the opposite to what it should, it tenses up, and that causes all sorts of consequences to balance and traction, let alone muscle tone and satisfaction. When happy, the muscles release massive amounts of triggers for endorphins, or endorphins themselves, it's still topical how exactly that mechanism works.The problem isn't so much temperature, since I can layer up for that. The problem is the loss of traction with icy/slushy roads, especially when many of the routes I would take involve unavoidable steep inclines/declines.
The bottom line is: "If it's not enjoyable, don't do it". And winter for most is not enjoyable. When cycling becomes a dangerous task, take transit. Or walk, also dangerous this time of year, but the consequences of slipping are far, far less than being on a busy roadway.
Now someone is going to trot out the accident stats for winter-time cycling in Toronto, showing little difference...not taking into account that the stats are not corrected for the 80% less number of cyclists on the road this time of year.
