Yeah, I do that. I actually keep my bikes inside my condo. There's really no other place to keep them. Not one I feel safe about. I thought at first it was just the computer freaking out going from 70F down to the outside temp of 45 or 40F. It also worked fine once I had been riding for about 20 mins. But by them, my ride data was hosed up. That's why I started to pop it off the bike and keeping the computer in the refrigerator. I thought it wouldn't take as long to get adjusted to the cold. But the downside to that is that the battery gets worn out 10 times faster.

I just referred back to the manual and it says the working temperature for the unit is 40F upto 104F. So maybe it's not meant to work at these colder temps.

Anyone else's cyclocomputers say they are only meant for plus 40F temps?
