This is what I use here in Sweden during the harsh winter:
-The Noth Face shell ski jacket (about 700grams). Tested several jackets, this one was the only one that worked for ebiking.
-Peperoni/noname black ski pants with the heavy termal layer. The Noth Face shell pants were too colorfull and actually not as good - to thinn/cold. Pictured Völkl ski pants, as I could not find the Pepperoni picture:
-Non cotton ski underwear/base layer.
-Fleece soft shell jacket.
-Magnum tactical boots, very light (about 700grams/half pair), waterproof and easy to pedal. Choose the ones without the zipper, zipper models are not reliable.
-Long fingered bicycle gloves. Those are comfortable both sommertime and during the winter.
-Ski socks
-Last but most important. The Chinease Military Force Jet Pilot helmet:
- Beon helmet (for you not wanting the apple juice attacks):
-Or this:
Just remember to use syntetic and wool materials, and avoid cotton at all costs. Most of the stuff ordered via aliexpress/ebay.
