Yes it is normal here, but it is also hilariously fraught with low-stakes peril. Dumpert always has vids of people busting their ass trying to make a turn or they hit an icy patch every year. I've had a couple of falls on ice here and I am not confident of my resilience long term doing that as I get older. So I avoid biking when it is frozen. But since that is only like a week or two out of the year, it is no big deal
