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.

Original replacement controller for the Ouxi V8 Ultra on 20 inch wheels. It is the S9F model on 48V that Ouxi fits in the Ultra as standard; check the V8 Ultra label on your current controller before you order.
This controller is not the same as the one in the V8 Ultra Mini or the regular V8, even though the housings look alike. It controls the motor based on the display, pedal sensor and brake signals. Swapping is done under the saddle and requires no experience.
Difference between restricted and tunable: it is in the software, not in the number of amps.
