main thing is to invest in clothing that can expel sweat out from your clothing. Getting soaked in sweat is going to make you miserable. Start out with less layers than what you expect and shed layers ( into your backpack) as you are getting warmer.

Also invest in mid to fat tires depending on the snow condition. Don't use road bike.

wear high visibility clothing because of reduced visibility in winter.

don't pivot around obstacles (snow covered potholes) suddenly, try to go over them or safely pivot by looking behind you.
