Bafang hub motor in winter conditions

[fin_rad]

Experienced probably a frozen gears issue while ago, not 100% sure what caused it though. Then yesterday after riding my RadRhino on deep snow and back at home, noticed there were melted snow around the hub motor:


There were some melted snow around the controller too:


Is this because my motor is the 750W (more power => more heat?) version or do the 250W motors have similar heating, so that snow will melt in about -5 C ? This is the first time I have been ridden in deep snow with ebike.

It will be interesting to start the bike next time and see how the gears etc. work...
