FAQ

Battery (2)

The battery represents roughly half of the price you paid for your NIU. So it should be maintenanced at least as well as the scooter itself.

[UPDATE: In 2018 NIU themselves published this page pretty much covering this FAQ entries content.]

Daily Use

  • Optimal charging temperature: 10 to 35°C
  • Using-temperature should not exceed -10 to 45°C
  • Do not unnecessarily keep on charging the battery when it is fully charged (Green LED lit on charger)
  • Do not completely drain the battery – try to charge at 10% at the very least.

(long term) Storing

  • Optimal storage temperature: 0 to 20°C
  • Recommended charge of 40-75%
  • Check charge-level every 2 months (e.g. put it into your NIU to get a proper readout)
  • Charge it to 100% when planning to use it again

Tips

To make sure you’re not “overloading” your battery you could use this engery-saving mains socket from Ansman (or something similar):

This automatically cuts of power when it falls below a certain (programmable) threshold, e.g. below 50 watts.

  • My ecu battery is showing 1% in the app. I use it every day. Just a glitch or am i in trouble…..?

    • I’d say it’s a glitch. You could test it by disconnecting the main battery, enable the alarm system and “simulate” a steal-attempt the next day. If you still get a push message etc I would assume it’s a bug.
      That said, after swapping my ECU for the new (Vodafone) one, my N1 is “offline” since 65days and since they reset my account/data at their side, both of my batteries are at 0% since days… if I would trust the App.

    • Your battery is losing points in proportion to its use. My battery looses 1% per 400km but this may vary depending on your charging and driving habits.

  • You just discovered one of the major flaws on the Niu scooters. The battery is emptied within 3 weeks when not in use, mainly because of the GPS. You can make it go empty slower by disconnecting the battery before you leave. Full drainage is bad for the battery and gives us an empty scooter, the manual says it shouldn’t be below 20%, right?

    => If Niu is reading this: please come up with a smaller adapter in the charger (so I can store it IN the U) and make it usable as a trickle charger (so I can just connect it to the charger until I need to use the scooter).

  • hello
    i have had to leave my Niu NS1 Sport unused for the last 3 weeks. I have taken out my main battery and the level was at about 55 as recommended

    However i can see from the app that my ECU battery is now at 18% – it was 100% when i left it. Will this be a problem?

    many thanks
    John

  • Hi, I’m wondering if it’s okay to leave my scooter outside during work hours when temperatures drop to about 0 °C or 32 °F and less. Before and after work the scooter is parked in a closed garage without heating. Ambient temperature should be not too cold.

    Thanks!

  • Hola buena tarde

    tengo varias consultas

    Cómo puedo cambiar el la hora de mi moto niu mlite
    Cómo puedo cambiar la bateria del control localizador

    Gracias

    • Hola Steffany,
      [This is an international NIU owner page – it would be nice to stick with english, so that everybody can understand your question and help]
      So you’re looking for help changing the time showed in the display? I’m sure those having a 2018 model can help out.
      As for the GPS-battery – I think it sits behind the front-shield underneath the handlebar. What’s the reason for changing it? Is yours broken?

    Control Modules (3)

    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

    N1s 2017 dealer TRA01V08
    N1s 2017 TRA01V04 ~53km/h 20%
    N1s 2017 TRA01V06 ~53km/h 20% – sporadic amperage display failure
     N1s 2017 TRA01V14  ~53km/h
    N1s 2017  TRA01C02  ~49km/h

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

    Category: Control Modules
  • 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

  • i have lingbo controller and it can’t use battery when i connecting battery the led always blinking and doesn’t stop i’m trying change another lingbo controller and still the same anyone know?

    • I haven’t seen the blinking myself, yet. But I assume it’s like with every blink-code: There’s a longer pause at the end of the code before it repeats.

    For the European market NIU chose the well-known Swiss manufacturer of ready-to-use GPS modules: u-blox.

    A press release  of u-blox reveals that they use the standalone GNSS‑Modul MAX‑7Q, which is using a Multi‑GNSS technology (GPS, GLONASS, QZSS und SBAS), making sure that tracking will work in any part of the world, at any time, independent from a single satellite system.

    Errors (1)

    Q: There’s an Error 30 displayed in my NIUs dashboard

    A: Generally, this is a Battery failure code.

    The official manual provides these reasons and how to fix them:

    Battery over-charging Stop charging. Start discharging if
    it is normal.
    Low-temperature battery protection (-20
    ℃)
    Restore the temperature
    The BMS temperature detection circuit is
    loose
    Replace the battery

    N1s owners reported several occasions when this happens:

    • Charging the battery externally(!) it only reaches a 90% charge. Putting it back into the NIU triggers Error 30.
    • Unplugging the charger right after the LED changed to green.
    • After driving downhill, especially when the charge is around 90%

    To conclude all these reports, the main reason for Error 30 seems to be the BMS which is built into the battery.
    One owner contacted the German/Austrian importer who responded like this:

    This error report can easily be deleted by simply starting your scooter by the start-button.
    Please mind: If Error 30 occurs, the “P” symbol will not be displayed in the dashboard.

    After driving for about 2 meters the BMS will recognize power consumption from the battery and you can use your scooter as normal.
    When starting your scooter make sure that the side stand is not swung out!

    This procedure did delete the Error 30 in 100% of all cases – maybe an update of the BMS (using the diagnose device) will permanently correct this issue.
    We’re currently working on new BMS boards which also might be  good for retrofitting.

    Generally, Error 30 will be triggered if you drive your NIU downhill for a longer distance and recuperation is ‘overloading’ the battery. One hint in the forums was to use the brakes every now and then and there will be no error displayed.

  • For you amusement…
    Today, after ~1000km I had my first Error 30.
    It was one of the “triggers” decribed above: I charged my battery in my office and saw the LED changing to green – unplugged the charger right away and put the battery back into my N1s about 30mins later.
    Instantly it greeted me with that damn error message. “on/off” and disconnecting the battery did not help.
    But gently pulling the brakes to enable the start button, then pressing start while pushing the NIU about half a meter did the trick.

  • Hello,

    I’ve had the code 30 also. Tried the trick explained by Thomas and the FAQ but didn’t work: the scooter would put itself in max 15km mode and turn off 5 minutes later saying the battery is at 0%.

    I put it back to the dealer who said the charger was defect. They gave me a new one (and I think they might have updated the firmware/software). Now the scooter works like a charm and doesn’t try to charge the battery anymore when over 90%…

    Cheers and thanks for this site!

  • I’ve experienced error 30 today 2 min. from home. Had loaded 100% and went downhill. The NIU stopped half way down the hill.
    Pretty disturbing! I pushed the scooter a few meters and turned the throttle and it did the trick. After trying to switch it off and on again to no avail I nearly gave up.

    Q: Can I import/bring my NIU from China into Europe?

    A: It shows that there are quite some NIU owners, who like to bring their beloved scooter with them to Europe (or even the US).
    There are two obstacles (besides shipping):

    • Get it registered (You’ll need an CoC)
    • Use the software (i.e. App)

    The CoC is provided by the official importer of your country. You might either ask them, or you’re lucky to find somebody at the NIU mothership who’s willing to help you. Without a CoC, riding your NIU in Europe is illegal.

    Concerning the software MyNIU.org reader Agus shared this valuable info on this (thanks, man!):

    I have an updated info -anyway- for every body here (I have just received this info from NIU; therefore this is official):
    The app for NIU scooters that have been bought in China and then shipped to Europe (privately) by their owners will not work (this does not apply to the ones that have been directly bought in Europe from official importers).
    I mean: for instance, if you are in China and are using a NIU scooter there, DON’T TAKE IT TO EUROPE; SELL YOUR SCOOTER BEFORE LEAVING CHINA; in Europe the app will not work.

    It would be the same, if someone in Europe, wants to sell any scooter to you that was previously bought in China, not in Europe.

    In other words: if the scooter was bought in China, and then shipped to Europe, you will be able to use the scooter for going anywhere (no problem for that), but the scooter’s electronic components (which are made only for China) will not allow you to use the app (you will have to forget -for instance- about the GPS function). The app will not be able to get connected with the scooter.

    (THIS IS OFFICIAL INFO -I REPEAT- FROM NIU).

    The problem is… that the price of NIU Scooter’s in Europe is approximately 3 times more expensive than the original price of these Scooters in China…

    Yes, technically there is a way… given it is street-legal in your country to have a child riding along with you.

    There’s a special child-seat for motor/electric scooters available: The Stamatakis Maxi seat is especially made for scooters and motorcycles and perfectly fits the N1s saddle.
    4 loops are used to fixate the seat to the saddle: One below the saddle itself, one around the front of the seat-compartment and two can be looped through the handlebars in the back.

    My daughter (aged 6) is just able to reach the foot-rests. Smaller children can use the supplied foot-slings which come with the Stamatakis.

  • Is this seat still available? I am looking at e-scooter options in Nepal, and am also looking for child friendly options. This looks fantastic, and would sway me to the Niu brand, rather than other.

    • While the seat is generally still available at many online-stores I’m not sure if any of those ships to Nepal…

  • I just wanted to say that I appreciate your post! I am actually an American living in China, so I am not part of your site’s target audience, but finding English information is still helpful for me. I am preparing to purchase a Niu scooter and I have been looking at child seat options for my 2.5 year old toddler. Since child seats in general are not widely used in China, the scooter options are very limited, and this is by far the best option I have seen and the best looking. Thank you for sharing!

    A: Straight away: The App offered for all non-Chinese owners is a piece of crap – and ages old.

    For a start, the Chinese Version is 3.0… you probably got 1.2.xxx – read all about it in this post.
    For those adventurous enough, there’s a way to actually use the Chinese App provided by fellow MyNIU.org reader Thomas:
    “Just make an account on the European app and then install the Chinese version, preferably on another device. Your password doesn’t seem to work but just reset it.
    You will receive a text message with a six digit code. Enter it, reset password and enjoy the app!”

    Currently NIU offers 2 main models outside China, the N- and the M-Series. But there are huge differences depending on the region you live in.

    China

    Obviously China has the biggest selection of models – so the N1 is available in 4 variations:

    Model Range Retail price in China
    N1lite 80km RMB 5499 / 715€
    N1C 100km RMB 5899 / 765€
    N1S 120km RMB 6899 / 895€
    N1S Pro 140km RMB 9999 / 1200€

    The M1 also has several versions:

    Model Range Retail price in China
    M1lite 45km RMB 3999/ 520€
    M1c 70km RMB 4699/ 610€
    M1s 90km RMB 5699 / 740€
    M1S Pro 110km RMB 6999 / 910€

    …and finally, there’s the model U (available in Europe from Sept. 2018):


    In contrast to the M/N models, the U does not have a BOSCH motor and offers just a drum brake in the back. Also only the 2 top models use premium brand batteries.

    Model Range Battery Retail price in China
    U lite 40km Chinese ~683€
    U civic 50km Chinese ~790€
    U sport 60km LG/Panasonic ~890€
    U pro 80km LG/Panasonic couldn’t find

    While the the diversity of models is already surprising, the price difference do knock Europeans off their socks… in average these are a quarter(!) of what you pay over here.

    Europe

    The current NIU model landscape over here is pretty easy to oversee:

    Model Range Retail price in Europe
    N1s 80km 2699€
    M1 Pro 70-80km 2299€
    M1s 60-70km 1999€

    The naming politics are a bit confusing… just looking at the estimated range the Euro-N1s is a Chinese N1lite. But it has a battery which is slightly higher spec’ed than the Chinese “S” (29Ah vs 26Ah).
    The M1s seems to fit into the Chinese M1c naming scheme, while the Euro M1 Pro matches the M1s in China.

  • i drive an ns1 pro. which i like very much for driving around town, but unfortunately
    my main use is to comment between cities that are 45km apart. for that the pro is a little slow, 60km/hr is just too slow, plus after a few months, the top speed decreases i had my pro for almost a year and i can only get up to 54, 57 depending on the weather and road conditions now. i use 2 battery which allow me a range of about 120km at full speed. that 140km range is great if your are disabled but no-one drive at 20km/hr, even a bicycle goes faster than that. the range on one battery is about 70km if you don’t go at full speed. in the winter forget it’s half of that, even though the battery are claimed to not be affected by the cold. beside the way i use my niu, its a great toy for playing around the city in heavy traffic for short distances.
    my question which i hope someone can answer is; when is the niu gtx or project x going to be for sell in china where i live? those are really the model that i need. i was one of the first to test drive the first niu ns1 in china when they came out and recommended to enlarge the compartment to fit a second battery. I’m willing to test drive the gtx and project x, here in hainan where i live.

    • Hi there,
      First off, I officially welcome you as the 1st Chinese reader who stepped into the light posting a comment – we feel honoured to that you found your way here 😉
      That said, because you’re lucky to live in the homeland of NIU and even speak Chinese (vs us helpless Europeans), you’re in a much better position than us to get more information about the GTX’s release… and if you do, we would be happy to hear back form you. Maybe in the forum?

      • Hello, I am also in China, but much more north than thierry pardon. I drive an N1s and get a top speed of 53 km/h , but that is short lived and on average I am in the 45-47 km/h range. The winters here in Beijing are cold, but nothing like my home country of Canada. I commute 20km to and from work (40km round trip) 5 days a week in all weather and seasons. The coldest months I can use up to 50% of my battery one way and in the hottest times no more than 35%. I have an average of 80km range driving agressively. I believe that the Beijing municple government is moving to ban electric scooters in 2020/2021 as there are too many accidents involving scooters. The blame is shared equally with vehicle drivers and scooter drivers. The level of impunity by drivers and high risk (running red lights/weaving in traffic) driving by scooter drivers has contributed to this decision. I doubt it will be enforcable, but if traffic violations/licencing of all vehicle/ENFORCEMENT was introduced, it is likley that the roads here would be safer and that scooters especially electric scooters would find more respect and they dont directly pollute.

    Motor (1)

    That’s probably the #1 question people ask. Officially, no, there’s no way to make your NIU running faster – the EU model is limited to 45km/h (or even 25km/h) which is the EU law for this kind of vehicles.

    That said, the motor and battery are definitely capable of delivering higher speeds. Some videos from China prove, that this is possible. Have a look at those videos here or here. Obviously driving faster will drain the battery faster, too.
    What they do is using a 2nd, aftermarket motor-controller in parallel to the original one. Here’s the post about this tuning.

    Depending on your NIU model, you might give these eastereggs/hacks a try… more recent 2017 N1s models won’t change their limit with these.

    I think you can imagine yourself that you would void your warranty as well as risking to get into serious trouble with your local police/insurance in case of an accident.

    Category: Motor
    • Well, I’d say this depends on the respectability of your dealer. A good dealer won’t void his customers warranty…

  • What about the Niu M+ Lite EU 2019. Does anyone know of any hack to make this model go faster than 25 km/h? Mine is not even doing 25 km/h.. 🙂

  • Hi, I would like to know if there is a way to unlock NIU N-PRO (NGT limited 45km/h)
    Thanks

    • Have you checked Alibaba and the other usual suspects for 2nd controllers? Theoretically it should be the same procedure like the N1s…

      • Thanks for your answer, I will surely check.
        If you have any link or tutorial I appreciate a lot if you can share.
        I am really newbe in this 🙂
        Thanks in advance.

  • Just got my NIU N1S 25km but not very satisfied with the low speed. Has there been any update about running faster this model?

  • I just need to make mine go 35 kmph in stead of the current 30 kmph.
    Just need to go a bit faster than the e-bikes.
    Isn’t there a way to change some software parameters ?

    • I’m not quite sure which post you mean, but the one about making the NIU faster is linked in the FAQ, saying “Here’s the post about this tuning.” – Well, and it’s very prominently featured on the top of the homepage.

  • I agree, I think all manufacturers will have to comply to EU law, which will restrict the use of speed delimiters set by OEM. This is probably related to emission related obligations. Sever penalties will be enforced to dealers and OEM if they don’t follow these rules.

    • Hey Novum,
      That’s the point. So dealers/importers have no interest in such “feature” risking to loose their status/license.
      As an owner it’s the same thing as with petrol scooters. You’re going beyond the type approval thus loosing it and you’ll get in trouble with your insurance of course. Not to mention the police/law 😉
      So it’s the same as it is since the 70s: The tortoise and hare game.
      As written earlier, I’m working a post about how this can be done technically. Just for informational reasons… >:-)

  • Following your conversation, just wondering if there is any progress on removing spseedlimit for 25 Km/h model?

    • Not that I know of. That said, I hadn’t had the chance to check the 2018 N1s 25Km/h model.
      These do have the indicator sounds (like the M1), but I’m pretty sure that the European importers are forced to remove everything in the firmware which is against EU laws :-/

  • Will this also be possible with the M1pro the same way as N1S? Because of the OTA Upgrade Thing… :/

    • As far as we know, the “Hack” or Easteregg is not working for the EU N1S models… and if I remember correctly, the M1Pro as being sold inside the EU as the same (soft) limit at 45km/h as the N1S.
      That said, OTA Upgrade is a very good point… that can spoil your modification-fun at any given time 🙁

      • That´s right, i already tried the Easteregg Thing on my M1pro..only the Light Sound Change works..

        But what i ment is to change the parameters of the BMS and the Controller to make it faster. As for as i know, the Controller talks to a RS485 Bus, which i could connect to my pc. But the problem is the software to change the parameters :/

        • Unfortunately it’s not just adjusting the BMS. The motor controller needs to be capable to handle more juice (as well as the battery).
          I’m currently writing on a post explaining all this and how ‘they’ make their NIU run faster… stay tuned.

  • Battery management circuitry is in the battery container. It is the motor controller that has to be reprogrammed, namely the rotation speed of the actuator field.

    • Karl, thanks for the clarification! Does the motor controller sit inside the motor or is it placed externally?
      Does it talk to some bus like the RS485? (You do know where this is going, don’t you ;-))

    Back: 120/70-12 Rim: 3.50×12

    • Recommended for bad weather: Heidenau K58 mod. Snowtex
    • [have your tire listed here]
