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.

Product information
The benefits at a glance
- Restricted to 25 km/h
- 6 km/h throttle
- Original part
- Suitable for: Ouxi V8 Ultra with a red motor cable
- Version: 6A, 250W, red motor plug, 5 connection cables with alarm
- Speed: limited to 25 km/h, throttle 6 km/h, not tunable
Limited controller for the Ouxi V8 Ultra, the version with a red motor plug and 6A. It replaces a failed controller and lets the V8 Ultra ride at the legal 25 km/h again, with the throttle as walk assist up to 6 km/h.
If you want more speed for your V8 Ultra, the tunable V8 Ultra controller is the right part; this 6A version stays limited. A black motor plug on your bike means a different model. Replacing: remove the saddle, transfer the five plugs, no tools needed.
The controller is the brain of your fatbike and drives the motor. Always work on a power-free bike, take a quick photo of how the plugs are positioned before disconnecting anything, and click each connector back into place. With this version, make sure the plug is put back with the same color (red) and the same number of pins, so everything connects neatly again.
Pro tip: tuck the cables away neatly after installation and secure them with a cable tie so nothing gets pinched. Can't manage it yourself or in doubt? Feel free to message us on WhatsApp at +31 6 82090642, and we'll help you out quickly.

Difference between restricted and tunable: it is in the software, not in the number of amps.
