Problem: The client complained about a knock at the bottom – it was as if a gnome was sitting there with a hammer and hitting plastic with it. However, the dwarf did not always do this, mainly after an energetic ride. Then, the sound could disappear and reappear with a new sharp push on the pedal.

Problem: Destruction (wear) of differential satellites and, as a consequence, noises (hum) when driving the vehicle.
