Consider doing any of this in -20F even without the wind chill. Now consider the battery on that bike in those temps.

I've had it be so cold outside that the door lock latch on my entryway door for my garage was growing ice crystals. This isn't a door that's on the outside. This is the door on the entry from the garage to the house.

Now imagine trying to bike anywhere with that and what is essentially a salt/beet sugar slurry in the roads with no one giving you right of way it even being able to see in front of them because they're either drunk, on the phone, only cleared a 3" hole in their windshield or "you just came out of nowhere" ;)

But hey, the summers here are kickass
