If you like to remove the under-seat compartment (aka “Bucket”) to e.g. check the engine-controller or fix a loose internal charger-connector, here’s a video for you: Continue reading How to remove the under-seat compartment?
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, … Continue reading Which ‘firmware’ versions are there?
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 … Continue reading Importing a NIU scooter from China
The NIU N1s’ main controller normally called ECU (hidden inside/behind the front panel) has an LED, and if it blinks, that’s a message 😉 Here are the blink codes: 1 Over-Voltage warning Battery voltage is higher than default value 2 Under-Voltage warning Battery voltage is lower than default value 3 Over-Current warning Instant current is higher than default value or Phase line short circuit 4 Locked-rotor warning Duration of Motor in locked-rotor status longer than default value Replace FOC controller 5 HALL failure Incorrect HALL input(Voltage) detected Replace Motor 6 MOSFET failure MOSFET power self-check failed Replace FOC controller 7 … Continue reading My controller is blinking. What gives?
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 … Continue reading Can I have my child riding the NIU with me?
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. Continue reading What GPS system is used in my NIU?
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 … Continue reading How to I handle my battery best?
A: Straight away: The App offered for all non-Chinese owners is a piece of crap – and ages old. The app got constant update cycles and is en-par with the Chinese version now. Like every piece of software, it’s not bug free, but I’d say it’s stable. Make sure you d/l the latest version – if you’re experiencing problems (registration etc.) the first thing is patience. Sometimes it takes a day until something found its way though the systems. If waiting didn’t help, it’s time to see your dealer. Continue reading The App is not working/has a bug
When new to the whole eScooter world, this is one of the first questions… and here’s a full post about the companies background. Continue reading Who’s NIU anyway?
First of all: Since the launch of their different models (~2016), NIU tend to rename their (sub)models every now and then. So depending on the year of delivery the same model might have a slightly different name which can get pretty confusing. Let’s take the model N as an example: Starting in China as “N1 civic” it became the “N1” after Honda claimed civic as their brand, which is the same as the “N1s” in Europe (+extra specs for ‘oversea’, ~2017). Then in 2018 it became the “N1 sport” and after the latest renaming in 2019 all models lost its … Continue reading What NIU models are available at the moment?
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 … Continue reading Can I make my NIU run faster?
A: Theoretically yes. But there’s no alternative outside China that we know of. There’s an alternative BMS available in China which enables you to build a battery-pack yourself… if you’re into this complex matter. Here’s an idea what to do: That said: If you think about importing one from China, better read this post before! Continue reading Can I use a different battery?
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 … Continue reading What’s Error 30?
Q: What brands of tires had successfully mounted onto a N1s? A: Owners reported these tires to be “compatible”, i.e. tested on their NIU: For the record, these are the required sizes Front: 90/90-12 Rim: 2.15×12 Back:Â 120/70-12 Rim: 3.50×12 Recommended for bad weather:Â Heidenau K58 mod. Snowtex [have your tire listed here] If you’ve mounted any other brand, feel free to share your experience in the comments (which then will be added to this FAQ). Thanks!
