We've had a steady snowfall all day, with an accumulation of about six inches. I was determined to ride, but after falling once a few minutes in to my trip, I got all tensed up and wasn't enjoying it. (I also wasn't loving the cars that were driving much too fast for the conditions.) Then I decided to keep one foot unclipped and simply turn my ride into a one-legged interval session. It was much more enjoyable then. I was far less worried about falling, since I already had one foot unclipped at all times, and could enjoy the wonderful quiet and stillness while still improving my pedaling technique!

Good for you for giving it a try! The more you do it the more your confidence, skill and balance level improves.

I use platform pedals in the snow.

i have had success with clipless pedals ni the snow, although my new pedals are the Crank Brothers clipless with platforms... they don't get clogged or frozen which can be a problem with Shimano/Ritchey type pedals...

i have studded tires and really enjoy riding in the snow - either mountain biking on snow-covered trails or commuting in the city -- the best is when it's cold enough to be frozen so not all mucky/wet... but of course too deep of powder is unrideable. a few weeks ago we had maybe 6" snow here in munich and we rode the local trails 2 times and it was WORK - don't look at the speedometer cranking through that powder!

weekend before last i hurt my knee skiing... so i've been restricted to one-legged riding (only 2 days and 70km last week), plus i'm out of town for work...

unfortunately they salt the roads here which is bad for my bikes and makes everything all wet and slushy... but some days it is AWESOME!
