Primarily for below freezing temps, but I figure it would be good in above freezing temps as well.

I'm not sure how bike speed matters, but it's usually between 13-16mph when there's snow on the ground.

Not sure how terrain matters either. Let's say all terrain. Sometimes flat, sometimes hills, probably no offroad stuff or anything.

Ice, yes. Rain, no - rain requires a rain jacket pure and simple, so not for this jacket. Snow, yes, for sure.
