If a person is riding their bicycle in -30C (without the windchill

lubrication does not freeze and cause the unwanted freewheeling?

My guess is it isn't the oil, it's water that's freezing causing the
problem. It's happened to me in the past. Strangely, leaving it out
works better as the ice is displaced never to return, but if it warms
up, the water pools, and refreezes again. Just my guess.

That's what I'm thinking too and that the water you mentioned is
condensation. I'd like to figure out a way to stop the freewheeling from
happening as it's annoying and dangerous plus I don't want it to become
a permanent thing whilst I'm 20 or 30 kilometers from home and on
country/backroads that do not have public transportation.

So taking it from a nice warm appartment out into the freezing cold is
drawing moisture into the mechanism. Perhaps first packing the void with
grease and thus reducing the volume of air to be affected and secondly
installing some sort of "felt" filter to catch the moisture before it
reaches the mechanism.
