Do you cycle when it's snowy/icy?

[Gastropod]

Not a cyclist bashing thread, I am one and I usually cycle everywhere!

But I never cycle on snow/ice. I'm just too scared that I'll skid and fall - I find it terrifying.

Where I live there is quite a bit of snow at the moment: although main roads are mostly clear, the side roads and cycle paths/lanes are definitely snowy with patches of ice. And yet I saw dozens of cyclists this morning, all merrily pedalling along as though it were the middle of summer, some with kids on the back, etc.

If you do cycle in snow/ice can you tell me whether you consider it safe, and what you do to make sure you don't skid or fall? I'd like to be brave enough to try, but not if it's dangerous!

Not cycling this week, saw scooter rider come off on black ice last week - it's too risky.
Sod's law means that I face planted walking to the station yesterday, slipping on an icy pavement. It caused me to see stars, and now I have a black eye, and bruised nose and chin. No broken bones or teeth - phew.

No, I tried to be heroic a couple of years ago. Cycled over a hidden drain cover with a sharp edge, split my tyre and had to walk home in the snow. The quiet roads and paths aren't gritted.
