Living in the Mid- Atlantic region means temperatures are in the 30’s and 40’s in December. Everyone I talk to puts their bikes in the shed and looks for indoor exercise venues. My advice, don’t be so quick to table biking outdoors. There are always days when the temperature moderates and warm biking gear works well. I even found a pair of heavy weight biking pants at WalMart. Old school lined leather gloves with tapered fingers are great for changing gears and keeping hands warm. If you are prepared you can still bike until Christmas.
