Which ‘firmware’ versions are there?

Q: Are there different versions of ‘firmwares’ available for my NIU and what are the differences/advantages/disadvantages?

A: Yes, definitely, there are several known software revisions around – all undocumented.

Here’s what we know so far (gathered by users all over the world), columns filled with data where available…

  • You’ll get the software revision from the App, it seems it always claims to be “latest version”
  • The “ECUKRS” version name hints towards the official Austrian importer KSR, maybe tweaked by them
  • Official dealers have a tool to update your firmware. If you have severe issues, it’s worth a try. That said, you might loose other nice features as it seems the newer releases are ‘tamed’ a bit.
Model Updated through Version V-Max emergency operation at comments
N1s 2017 controller update & OTA ECUKSR1.3 (Nov 17) 47km/h 15% + smoother starting

– less lively

If you have a revision to be added, come and join the forum – there’s a special thread for this 😉

  • Additional comment concerning changes between TRA01C03 and TRA01C10 : The scooter does automatic recubation when the speed exceeds 50km/h downhill (it slows down). I did not see this behavoiur with the TRA01C03.

  • There is a mistake in my first comment: emergency Operation limit for TRA01C03 is 10%. The 77% is the battery level i needed to do the upgrade to the TRA01C10 FW version….

  • I got my N1S 2018 shipped with TRA01C03:
    Vmax = 51km/h (downhill more)
    Emergency Operation at 77%, maybe 70% (67% was not enough and the upgrade did not start!)
    I did the updgrade to TRA01C10 today:
    Vmax = 50km/h
    Emergency operation not yet tested.
    Clock works now. contact to app seems more stable. It is now possible to disable GPS.

  • Well… please… is there any place where I can download that software…?
    I am very interested on that…
    Yes… I know… only official dealers can do that…
    But… I repeat again :)… is there -do you know- any place where I can download the software?…

    thanks
