I've tested my new commuter bike (with its new studs) in a variety of conditions--blizzard helped--and I now know winter biking is tricky! There are numerous variables at play--slush, snow, and ice-- with every ride and conditions change as temp drops. Add cars, trucks,and buses to this stew and this is challenging scheise. I walked some sections of my ride just to be safe.

But when the bike trail is packed or its just icy and those studs dig in, I love it! I've always taken biking for granted, but this is different. This requires a new skill set.
