A technician rides an electric bike on the snow, passing a container and crates on the ground. A technician uses an electric fatbike to get to the summer camp area from the station. Immediately after arriving, he removes the electric battery and deposits it in the nearest building where the temperature is positive. If he forgets the battery outside, he will have to push the bike on the way back because the intense cold will have drained the battery.
