Changing the tire on the rear wheel of your NIU e-scooter (by simple means)

- The time-consuming part of changing a tire on an NIU e-scooter is not the tire change itself, but the removal and installation of the rear wheel (= motor). If you still want or need to try it yourself, for example because you do not have a NIU dealership nearby, you can find some inputs here.
We do this mostly by hand, because maintenance and repairs with our concept usually take place at the customer's front door. - ยานยนต์และพาหนะ

Hi Mobilize, I hope you can also do a video replacing Wheel hub bearings for this unit too. Thumbs up for your great videos as usual. ~Klinton of PH
Hi. Thanks for your kind words and the input. Yes, we should do that... However, it's a very rare situation. Within four years and 200 NIU scooters we only had to replace those bearings on a front wheel once.
Quick note. I have an MQi GT. I just did this (wish I'd seen the video, but I got it done, and the MQi is slightly more complicated for removing the under battery pan.) An important point I found out the hard way is that you may have four washers that go on the axle, and they need to go on the right way. There are four washers on mine. Two thick ones with a slot to fit the axle and a tab on them, and two more. The two regular round ones are not the same. One is thinner and one is thicker. The thicker one goes on the brake side. If you get them swapped, part of your brake caliper will rub on your rotor. It'll make a pretty awful grinding sound, and won't go away when you brake. The two regular washers go innermost. After that, it looks like he shows it in the video.
Thanks for your thoughts 👍🏻
It was a very helpful video. Self-replacement would be possible with just a few tools. Thank you.
Nice stuff, very educational. Relaxing to watch like an ASMR
A very interesting and informative video - Thank you.
I take it with the wheels being so small wheel balancing is not required.
Thank you! And yes, correct. Balancing the the back wheel (motor) would be quite a challenge anyway...
You are a gentleman.
Thank you for the help you have given.
🍻
Great video
Excelente video
Excellent; thanks for that.
Fantástico, muchas gracias por compartir.
I would love to put dirt knobby tires on mine once I get one, haven’t seen that done yet. 😜
Nice video 👍 While we here in china , we don’t really use torque wrench, we use the electric wrench powerful to tighten that motor nut 🤣 they don’t care 😁✌️
😃Thank you. I fully understand. It's actually the only nut we tighten with a torque wrench.
Really informative thank you but you should have captioned the torque spec on the rear axle nuts because it not really visible looking at the torque wrench in the video.
Yes. Will try to add it somehow. It shoud show 75.
Thank you for this video.
What is the size of the nut you used for the back wheel?
27 for NQi GT, NQi GTS, MQi GT, 24 for NQi Sport, MQi+ Sport.
Excelente video.
Cuánto es el torque para ese tuerca de la llanta?
¡Muchas gracias, José! El torque es 75 nm.
@@mobilize-switzerland even the front bolt is 75Nm? In the rear I have tightened the 2 bolts + 2 nuts at 75Nm. Is correct? Did I just had to tighten the big (27mm) nut at 75Nm?
@@alezanott 75Nm for both bolts and nuts at the rear wheel should be fine. Front axle less: 60Nm.
@@mobilize-switzerland perfect thank you!
Did you put on the tyre with the yellow dot marker directly opposite the valve for inflation? That is where the balance point of the tyre is. What make and type of tyre did you put on. Curious?
Torque wrench settings please? The picture was blurred
Thanks!
No, the dot indicates the lightest part of the tire. This should be positioned at the valve. The tires are Mitas MC20 Monsun.
@@mobilize-switzerland thank you.
What was the torque wrench settings for the wheel nuts to the swing arm and brake calliper?
@@stumpusMaximus Send me an e-mail to remo@mobilize.ch (by mentioning your NIU model) and I'll send you the service manual. Greetings, Remo
What tires do you use for the NIU NQI NGT Pro?
Mostly Michelin City Grip 2 (rear wheel) and City Grip (front wheel). 120/70-12 & 90/90-12.
i couldn't really tell through the video but what was your torque wrench set to?
75Nm
Mein Niu NQI Sport zeigt seit einem Sturz durch den Sturm der letzten Tage ( bei der Arbeit passiert), den Fehlercode 60 und in der App ist er seit dem nur noch offline. Kann es sein das sich durch den Sturz die SIM gelöst hat ? Gibt es dafür eine einfache Lösung oder muss ich wohl oder übel deswegen zum Händler ?
Passt eigentlich nicht so zum Beitrag :-) Code 60 hat mir der SIM-Karte zu tun: SIM card identifiaction failure. Kann theoretisch sein, dass durch den Sturz in der ECU und ihrer integrierten SIM-Karte irgend ein Kontakt wackelt. Kann aber auch sein, dass der kostenfreie Service von NIU zu Ende ist (wobei dann dein NQi Sport 3 Jahre alt sein müsste). Ja, Händler! Zumal du die ECU nicht selbst öffnen sollst.
Do I have to undo the seat and disconnect to replace the tire?
Of course. Shown in the video. How else would you disconnect the cables between the motor and the motor controller?
Hi, would you tell me the wheel bolt tightening pair?thank you
You mean the torque? 75 nm for the main nuts on the rear wheel and around 60 for the others at the rear and on the front wheel.
At which pressure do you usually inflate the 2 tires? Thank you
2.5 bar rear, 2.3 - 2.4 bar front.
Hi, what sizes are the sockets on the socket wrenches you use?
I can't answer that without asking back. Which NIU scooter do you ride? What socket do you mean? Greetings, Remo
@@mobilize-switzerland Fair question! It's an MQi GT, and I'm referring in particular to the large socket used to loosen the bolts holding the axle to the frame.
@@michaelkimmitt6818 Understood. A few MQi GT (Evo) will get in tomorrow. I'll check an give you a feedback.
hello friend, the figure for the tightening of the dynamometer please (trouble on the video), thank you
75 nm 👋
Kommt in zukunft noch ein video dazu wie man die Scheibenbremse bzw die bremscheibe zu wechseln ist sowohl hinterrad als auch vorderrad ? Meine bremsscheibe vorne hat einen schlag und würde es gerne selbst tauschen, allerdings weis ich nicht worauf ich zu achten habe
Ist nicht vorgesehen, da sehr simpel. Du musst ja lediglich das Vorderrad abmontieren und mit einem Inbusschlüssel die 3 Schrauben lösen, die die Bremsscheibe fixieren (und mit denselben Schrauben die neue Bremsscheibe befestigen). Hast du Fragen dazu?
@@mobilize-switzerland Dachte da gibt es ein vorgegebenes Drehmoment ? Na dann ist ja gut , dachte es gibt irgendwelche Fehler die einen passieren können das die Bremse abfällt während der Fahrt oder so
@@davidziegler7053 Den Bremssattel kannst du dranlassen, wenn du das Rad wegmachst vorne. Einfach was unter den Roller stellen, damit Rad bzw. Gabel oben bleibt. Rechte Bremse nicht mehr betätigen, wenn Rad weg. Schraube mit ca. 60 nm anziehen.
What's the stuff you are spreading on the tyres, at 5:20?
This is tire mounting paste to make the tires slide better. You can take a soap-water mixture as an alternative (if at all necessary).
I would like to put wider tires on NIU UQI + something sporty DO YOU KNOW WHAT SIZE I NEED
No. But you can use the original dimensions of the UQi GT's tires (rear: 100/80-14 / front: 90/90-14) and talk to tire pro. There is certainly some technical tolerance in dimensions.
@@mobilize-switzerland thank you for your help
@@davidroter5580 You're welcome. Thanks for asking. I would be very interested in what you finally do. So: Keep me/us posted! 🖐
Looks very easy compared to chinese scooter tire change.
Well, NIU scooters are chinese...
原装车还是太慢了n1s换个南京远驱72360型号控制器可以提速到90-100迈
This is a video about changing a tire, not about speed.
@@mobilize-switzerland 🙁
Come over to my house and I’ll pay you to do that to my NQI!
