I'm not a fan. I have the layers but even that doesn't bring the motivation.
My own experience of winter riding, is that you get some really crisp, wind free days with clear blue skies.
Plus, you get less traffic on the roads.
It all adds up to an idyllic riding experience.
When it comes to keeping warm, it's the extremities which are the challenge (fingers, toes, ears). The rest of the body keeps itself warm by doing stuff (pumping pedals uphill is a great way to get warm).
You don't see footballers playing an away CL game in Minsk in January wearing bloody great jackets and layers of leggings. They might chuck on a vest and some will wear gloves, but that's about it.
