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.

1 minute Just wire cutters No experience needed
  1. Fatbike on its stand, with the motor in the rear wheel

    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.

  2. Cutting the cable tie around a fatbike's motor cable with wire cutters

    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.

  3. Cutting the second cable tie at the motor plug

    Cut the second cable tie too

    Now the plug hangs free and you can get a good grip on it.

  4. Holding a fatbike's motor plug by hand

    Hold the plug on both sides

    Hold it by the thick plug housings, not by the thin wires.

  5. A fatbike's motor plug pulled apart, with the pins visible

    Pull the plug firmly apart

    It's a tight fit, so don't be afraid to pull hard. The plug won't break.

  6. Red inside of a fatbike motor plug with pins

    Look at the inside

    Where the pins stick out you'll see the colour: red or black. That's your motor plug colour.

Done? Push the plug firmly back together (the pins only fit one way) and, if you like, put a new cable tie around it.

Product information

The benefits at a glance

  • 48V - 6A
  • Q9 label (model S9F)
  • Aluminum housing
  • Suitable for: Ouxi Q9 (20 inch) with type plate Q9, model S9F
  • Version: 48V, 6A nominal, brushless DC motor controller, undervoltage protection 39V
  • Speed: factory limit of the Q9, no tuning function

Original 48V controller for the Ouxi Q9, model S9F with 6A nominal. It is recognisable by the Q9 type plate and replaces a faulty controller without any settings to change.

The Q9 controller is not interchangeable with the Q8 one, even though the bikes look alike. It processes the signals from the display, pedal sensor and brakes; if the Q9 is left without assistance, this is usually the culprit. The swap is done under the saddle with five plugs.

Software

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