One thing is for sure. You guys deserve a lot of credit for doing longer rides in the weather. I'm just doing it for fun and exercise and 2 miles so it's a lot easier.
I went last night during a snowfall and the bike handled beautifully. The only time I slipped was when I was making a tight turn in my driveway. During the ride it helped to be able to ride in car tracks. Less resistance. My typical 2 mile route did not feel much harder. There was not much wind. High winds make riding more difficult than that particular snowfall. It was not very deep though. We might have gotten 1.5" total.
I will say this too, the TYPE of snow we get varies a lot. I live a block off of lake Michigan so typically it's a heavy wet snow where I'm at. But it can vary. Sometimes it's light and fluffy. I would imagine other areas experience the differences in types of snowfall too. It's almost like you need a few different bikes set up a few different ways for what type of weather it is. LOL.
Honestly, riding in it was a lot of fun. I just like being outside and I'm thankful to be able to do it. I'm glad I'm not trying to commute like that though. I would be most afraid of drivers.
