DIY Videos

Yes, there’s a growing number of DIY videos showing in detail how you can fix problems or enhance your NIU yourself.

Some are there for quite some time but probably somewhat hidden in a post or an FAQ entry. So I thought it’s about time to also collect them into a single post.
Alternatively you can also just subscribe to the MyNIU.org YouTube channel 😉

But first, a stern word of warning:

If you do what I’m showing in these videos, you will do this at your own risk!
I’m not going to be taken liable for any damage to your NIU or your health!
If you’re unsure if you are able to perform these stunts, then please don’t do it!

Fixing things

Removing front panel and check the hall-sensor

Let’s start with the newest (and longest) video yet. I recently got a strange and not so common issue.
When switching on my NIU I often get an Error 140. The user manual says it’s a problem with the throttle… and that’s pretty much true.
While I can simply ignore the error message and just start riding my NIU I will have a speed-drop every now and then. It then slows down from top-speed (~50 on the speedometer) down to 40 where it stays until I do a full stop and accelerate again. This behavior comes and goes. So it’s not really reproducible. There are 3 possibilities:

  • Broken hall-sensor
  • Broken bowden-cable
  • A loose connection somewhere between the hall-sensor and the motor controller

In any case, I have to check them and open up the front-panel to measure the voltage coming out of the hall-sensor.
Also, I have to dismantle the throttle-bar… a good opportunity to add all this to the DIY videos:

Preventing the sidestand from “touching ground”

This a common problem every NIU owner will face some time. In a sharp left corner, the sidestand will touch the ground.
Quite dangerous… so let’s fix that:

Removing the under-seat compartment

After some time my charging-connector came loose – yet another reason to make a video to show how to remove that compartment, which is quite easy and gives you the chance to take a look at that omnious main controller:

Enhancements

Adding a gas-spring to your seat

This is meant as a yet simple but handy facilitation in your daily NIU usage. Add a gas-spring underneath your seat and it will automagically open itself when being unlocked. It also stays in place while you dig for stuff in there, preventing it from hitting your head 😉

  1. It also seems possible to change the indicator sounds…

  2. Hi, Axel.
    Few comments on your “Removing front panel and check the hall-sensor” video. There was an issue with pulling out two plastic pistons from the lower side of the front panel. You said “They have small pins in there you have to pull”.
    More common way – the core pins shouldn’t be pulled, but should be pushed inside the pistons, so the pistons will be loosened and easily be pushed out.

    1. Yes, you can push the pin inside which is definitely more convenient. The downside of doing it that way is, that the pin is pushed all the way through the piston and ends up rattling somewhere inside your scooters chassis… That leaves you with a piston without pin and a lot of work if you really up to getting the pin back.
      OTOH if you have found a source of fitting pistons (cheap at ePay etc), that method is just fine.

      1. Sorry Axel, evidently I didn’t explain my point clearly. When you push the pin inside the piston there is a stable position of the pin, about 3-4 mm from the piston surface, so the pin stick this position in the piston and do not go “through” the piston, and at the same time you can easily pull out the piston. Please look at a video, it is in russian, but I hope it is clear.

        The same piston we have in our N1s.
        Best regards, sorry for inconvenience,
        Eduard.

        1. Got you. So it’s a thing of pushing it gently – just enough to click into the 1st notch.
          That said, you can push it through… I know that, because I have one pin rattling in my chassis. And no, it wasn’t me 😉
