There's no such thing as bad e-bike weather, just poor clothing choices! Most important advice I could offer: studded tires.
This will be my third winter of riding every day. My coldest day is -36 celcius (without wind chill factoring in which would take it to who knows what). My rides last about an hour each way. One cold stretch lasted 3 weeks. Typical is about -15 for three months of the year. My commute times increase by about 10 minutes (12%) on really snowy days.
On the worst days of the winter, commuting by car is a total gong show. Many people spend two to three hours to cover the same distance my bike does in an hour. My limit is 15 cm of fresh snow, more than that and I stay home. I haven't had to take a weather day yet in three years.
Here's what I use:
- 26 inch mtb, 5304, two 48v 10ah pings in parallel mounted in panniers on front rack, 35amp xlyte pedal first controller.
- on really snowy days, the spokes get icicles on them, no issues with performance though, the bike runs great in the cold
- use chain lube formulated for cold weather, it does get more difficult to shift on the extremely cold days
- studded tires if you ride on any kind of snow/ice
- wrap the battery in closed cell foam and always store/charge indoors (ping)
- its dark both ways for my commute in the dead of winter, at the speed we go, lights are very important, I've tried lots of off the shelf hid setups, and so on, ay up is the only thing that has lasted more than a few months
- good reflectors, I have front and back blinky lights too
- lots of layers with a wind proof shell
- most days its a certain thickness of long underwear with wind proof cycling pants on the outside
- really cold - thickest long johns, ski pants
- pull on leather shoes rated for -15 - I'll wear these until about -10
- -15 or colder - full on winter boots that are flexible and rated to -45
Above freezing - just the cheap shield type glasses, preferably a clear lens
Below freezing - ski goggles, clear lens
Below -5 Celsius - simple balaclava
Below -15 balaclava, tuke, neoprene face mask on top of the balaclava
I tape all the air holes on my helmet in the winter and also have wedged in closed cell foam to keep it a bit warmer.
- I carry a pair of hot pack hand warmers in case I have to fix anything that breaks
- Tried heated gloves, too much fussing with batteries
Depends on the temp but here's what works:
+5 and above - regular bike gloves
0-5 Celsius - work gloves, all leather
- below zero to -5 - winter gloves without the liners
- 5 to -10 - winter gloves with liners
- 10 to -15 winter gloves, liners and over mitts
- 15 to -20 winter mitts
- 20 and colder winter mitts and over mitts

Tony Stark was able to build this in a cave. With a box of scraps!
