Here's what the street in front of my house looks like:
It's not obvious from the picture what's going on here. The ice is solid for sure. It's not a clean, smooth sheet. It's rutty and bumpy. At the moment it's snowing lightly, so there's a film of snow over the top of that.
This makes for really interesting riding. We took two rides today: first, we took Maddie to school. Liza did great. She was on the Fuji and hauled Maddie. No issues. We took it nice and slow. Then, I rode to the doctor's office this afternoon. I tried going a bit faster, maybe 10 mph? I went down in a flash. I guess my front wheel just slipped out from under me. It was sudden: one second I'm just riding along (JRA), the next second my bike, my frozen-solid water bottle, and I are having a little skate down the road -- sliding silently and effortlessly.
Riding on this stuff -- even with studs and on a fixed gear -- really takes equal parts of luck and skill to get around on. I took a spill, I messed up my pants and my knee a little; no harm to the bike. But really, given the overall distance I rode today (probably about 6 miles), and the fact that I'm pretty new at this, I'm pretty pleased with my accident to miles ratio.
I'll be keeping it much slower until this ice melts away. 5 mph tops.
