I found little on Youtube about the DPC14 controller used on the new Biktrix Juggernaut Ultra.
Attached is a photo/text description of how to set up the controller the way you want it.
Hope this helps. File is in pdf format so you can print it.
I see that the DPC14 display storage temperature is -30 C. I was thinking of storing the bikes in an unheated garage but we can get -40 C in winter so I'll have to take the displays off, unplug and bring them inside for the winter.
