Important-ES2/4-dates hardware versions v1.5 v1.6 came out on sale?
 

This is important info for buyers. Later versions has less or no problem with for ex. brake/light issue,
and has a new motor, new version battery and more.

I´m talking about the hardware verision not firmware.

The first 4 digit nr on the serialnr tells you the date of manufacture. 2 first =year - 2 second = week of the year.
Mine is 1907 meaning it was manufactured in the 7th week of 2019.

My question is how to find out the release dates for the versions 1.5 and 1.6.

The version info is printed at the short side if the Ninebot box at the bottom right corner.
Would be great if someone could write the first s/nr 4 digit & version nr please.

Jocke
