bikerbobbbb I commute year round down to 5F. My three bikes sit outside in an unheated shed. Below 15F the bikes sometimes feel kinda stiff for a couple of minutes, and using the pump to top off the AirZound air-horn can be a little tough. Also, the cable locks can be stiff. But I've never felt like the seat or bars are cold. On the other hand, I've been wrapping my bars in 3/4" pipe insulation for a dozen years due to hand issues. And each bike has a padded gel-seat cover...well, my snow bike has an actual padded gel seat (with springs). That may have something to do with it.
