I rode my Cruzbike Freerider using Schwalbe studded snow tires a few years back (before I broke my leg in a car accident, won't do it anymore, as I'm a little afraid of falling on it now), it was fun, if a little slow, you don't want to go fast on snow covered or icy roads. The conditions going from lightly snow covered, with the occasional icy patches, to bare roads after they were salted. Traction was pretty good, but I used regular pedals, as I would often need to put a foot down when traction would break a little on ice, the bike would slide a little, but never that much, my front wheel has never washed out, my rear only once, I didn't fall because I was able to put my foot down for balance. On bare roads, I could go to about 80% of my regular summer tire riding speed.
At the time, I weighed 220 lbs. I was in my late 50's then.
I have been riding the Freerider since 2008, but stopped the winter riding since my 2015 car accident. I now ride indoors on a trainer in the winter.
Hope this helps,
Denis
