URGENT! For the rear tire change can I just remove the bottom plastic and remove the rear tire or do I need to remove the top plastic as well as bottom?

It should be enough to remove the bottom grey cover to get to the axle nuts holding the rear tyre in place as seen here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2GT5LiTJ8D8.html If you have a flat though, I would first try to repair it with a tubeless tyre plug kit and you won't have to remove the tyre.

Asking about speedlimiting, i know the limiter is in the software but... This might be stupid thing but have anyone tested if you try another lcd screen on niu kickscooter like s866 (programmable lcd) can you set new parameters in and tune speed and current limiting with another lcd computer or is it just the controller that sucks. 🤣 Just wondering if there is something little different lcd screen with niu when they program the controller from factory like eu or us.. meaning if they just use different lcd screen on the factory when they do the parameters with multiple buttons and then put the "original" sceen on it and sell them..? Maybe i just order 1000w aftermarket controller and forget all these thinking and pain 😅 sorry for the unclear explanation

No, unfortunately I did not come across a problem of the scooter not charging at all. Not sure what might be causing it. The fact that the charger turns from green to red when you plug it in should indicate the scooter is charging. If it is not, you might have to contact NIU over at Global-Service@niu.com to see if they have any suggestions to try.

Error 33 is the "Battery open-circuit or imbalance warning". I hove not come across this error myself so not sure what might be causing it.

My guess would be, if you haven't used the scooter for a year the battery might be too depleted for the scooter to start.

Cruise Control is available on the KQi2, but not in the EU. The International/US model has it enabled afaik. But due to restrictions in some EU countries NIU and other scooter manufacturers like Segway have disabled this feature in Europe. I hope NIU brings it back in countries where its not specifically restricted, or when you use your scooter on private property.

I will definitely consider doing guides for other parts of the KQi2.

After that it should be the same as on any other scooter.

Glad you liked it. Not planning to do a tyre change video, until I have to. On tubeless tyres if you get a small flat its easier to use a tyre plug kit (as used for car tyres) to fix it rather than changing the whole tyre. As for wheel removal, that should be straight forward, for the back one just remove the bottom black plastic cover in addition to the top cover, as I mentioned in the video, and you should get full access to the rear axle nuts. For the front wheel you need to remove the reflective stickers, and remove the screws to get to the big axle nuts to remove the wheel. I plan on doing a repair video on the error03 issue with the throttle, which will involve dissembling the display and getting the throttle off the handlebars.

@Lantea13 2 года назад
Thanks. There is no speed limiter to disconnect, the speed limit is programmed in the controller firmware, afaik. On scooters that are controlled though a mobile app (e.g. Ninebot Max), you need to change the firmware to unlock the speed, and so far on the NIU that is not possible as far as I know. You can ask NIU about it, the hope is they will find a legal way for users to be able to unlock the scooter speed when they use it on private land or in countries where higher speed is allowed.

If the battery re-connect does not work you need to send it for repair unfortunately, or ask NIU to send you a replacement controller and replace it yourself, since you already had the scooter opened up, you already did the hard part :) I heard back from NIU about the problem, and it was related to soldering of some components on the controller. They are taking new precautions and putting extra quality control steps in place so this should no longer happen in the future.

That would be nice for riding on private land or in areas where higher speed is allowed. I hope NIU comes up with a solution themselves that would allow them to comply with EU laws on speed limits and cruise control, but also enable them to have a direct option in the NIU app to unlock the speed and features such as cruise control when the user agrees its for use on private property and takes full responsibility for the unlocks. That way NIU is covered and users get more options in using their scooters. However not sure if legally such option is possible in all EU countries. Alternatively maybe the community comes up with a solution as they did for some other scooters, but personally I would prefer an official way to unlock the speed and advanced options.
