Step by step How do I check my motor plug colour?
How to check which motor plug colour your fatbike has
All you need is a pair of wire cutters and it takes a minute. The colour is on the inside of the motor plug, so you'll need to pull it apart. That's fine: it won't damage the plug.
-
Go to the rear wheel
Put your fatbike on its stand. The motor is in the rear wheel, and one thick cable comes out of it: the motor cable.
-
Follow the motor cable to the plug
The motor cable runs along the frame to the first plug. It's usually held in place with two cable ties. Cut the first one.
-
Cut the second cable tie too
Now the plug hangs free and you can get a good grip on it.
-
Hold the plug on both sides
Hold it by the thick plug housings, not by the thin wires.
-
Pull the plug firmly apart
It's a tight fit, so don't be afraid to pull hard. The plug won't break.
-
Look at the inside
Where the pins stick out you'll see the colour: red or black. That's your motor plug colour.
This controller only fits if the inside of your fatbike's motor plug is this colour. Not sure? You can check it in 1 minute.

Customer Reviews
Sits tight, nothing rattles. The order was completely right. I'll come back here.
Good replacement for the original controller, neatly handled.
Clicked straight into my H9. I got good advice beforehand.
Handy that it says which plug it is.
The bike shop had it in there in a flash. The packaging could have been sturdier for me. Just well handled
This one fitted where the previous one didn't. Better than I expected.
My son's H9 rides again.
Fits the H9 as described. My wife is happy with it.

Tunable controller for the Ouxi H9 with black motor plug. Combined with a tunable HC80 display with killswitch, with or without NFC, the H9 goes up to 50 km/h; the killswitch sets it back to 25 km/h for public roads.
This part fits only the H9 with black plug; for the red version there is only a limited controller. Check the colour inside the motor plug with the Colour Check. You replace it under the saddle, in about fifteen minutes. Riding tuned is only allowed on private or closed-off terrain.
Replacing a new controller is actually very simple: there are only 5 cables you need to connect. Still can't manage? Feel free to WhatsApp us at 06 82090642, and we'll help you out quickly.
Pro-tip: first remove the saddle from the bike, this makes it easy to access the controller to replace it.
WhatsApp chat only. We can't take calls, not even via WhatsApp.
Important: This controller only works with the H9, and only in combination with a black motor cable. Do you have a different fatbike model? Then you need a controller that matches it. On our site, you can find the correct controller for your model.
Difference between restricted and tunable: it is in the software, not in the number of amps.
