NIU Scooter Speed Unlock – USB Controller Installation Instructions

This guide will provide instructions on how to install the USB controller upgrade for your NIU scooter.

Installation instructions

1. Disconnect the battery and then open the trunk.

2. Unscrew the four screws from the trunk and take out the trunk. You can remove the trunk by disconnecting it or balancing it on the scooter. Now you will see your scooter motherboard.

3. Disconnect the motherboard power cable and then remove the screws and cables from the motherboard.

4. Replace the old motherboard with the new motherboard and screw the new motherboard into the scooter. 4 might not fit due to the controller being larger, but 2 screws are sufficient.

5. Screw the 5 coloured cables back into the motherboard and make sure the screws are tight.

6. Take the two headed cable and stick the side with the black USB head into the new bought motherboard. Then you take the other side of the two headed cable and stick it into the KZQ side.

7. Then insert the power cable of the scooter into the black box on the “CAR” side 

If you are unsure about the installation, please contact our customer service. Do not install the motherboard by yourself without instructions as it will harm the motherboard and scooter. We are not responsible for reckless use

N1: For the N1 the instructions are the same except there is an extra 6 pin HALL plug on the original motherboard.

  1. Open our provided 2 headed cable and insert the 6 pin cable into the adapter. 

Trouble Shooting

Be careful with an electric screwdriver that you don’t damage the screws, if this happens it is possible that you cannot remove the screw anymore. 

  • The two headed cable is installed wrongly, reinstall the motherboard again according to the instructions
  • The two headed cable has come loose after you put back the seat.

The parameters for you scooter are incorrect, message customer service so that we can get you the correct programming software.

The voltage inside the parameters of your motherboard is incorrect lets say you have a 48V M+ scooter, but the settings are for a 60V N1S.
