Hi,
How is called the black connector?
It is mounted sulla hoverboard engine

The best thing you can do is go onto Farnell or Mouser, go to their connectors page

Select all connectors with the same pin pitch & number of contacts
then select the specific manufactuer (if it is printed on the connector)

then look through the list for ones the look similar and compare. It's what I usually do and I've got a pretty good track record doing it.

Looks like automotive connectors. But since your picture came from a scooter page that would be a search term. The ones on the right are referred to as male bullet connectors. The ones on the left are referred to as modular connectors here: https://www.google.com/search?q=scooter+connectors&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiel_qv4erRAhUI6mMKHXe3Bz4Q_AUICSgC&biw=1489&bih=887#imgrc=88dpQ97ZsXj0JM%3A
