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.
For the red motor plug

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

  • Tunable up to 50 km/h
  • Restricted: 6 km/h throttle
  • 5 cables, with alarm
  • Suitable for: Ouxi Q8 with red motor cable (tunable version)
  • Version: 500W, red motor plug, five connectors including the Q8 alarm cable
  • Speed: Q8 tuned up to 50 km/h on private terrain, delivered at 25 km/h

With this tunable controller and a tunable display with killswitch, the Ouxi Q8 rides up to 50 km/h. It replaces the original limited controller and uses the same five connectors, including the Q8 alarm cable.

The Q8 only comes with a red motor plug in this version; if you find a black plug, get in touch via WhatsApp first. Fitting is simple: lift the saddle, unclip the old controller, connect the new one. Riding tuned is not allowed on public roads, where 25 km/h still applies.

Good to know

Fitting a new controller on your Ouxi Q8 is actually very simple: there are only 5 cables you need to connect. Still not working out? Feel free to message us on WhatsApp at 06 82090642 and we will help you quickly.

Pro tip: take the saddle off the bike first, so you can easily reach the controller to replace it.

WhatsApp chat only. We can't take calls, not even via WhatsApp.

Please note

Important: this controller is intended for the Ouxi Q8 and only works in combination with a red motor cable. Do you have a different fatbike model? Then you need a controller that matches it. On our site you will find the right controller for your model.

Software

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

Ouxi Q8 tunable controller: the red-plug controller for your Q8

The Ouxi Q8 is a fatbike for long rides, also with two people. This controller is the part that drives the Q8's 500W motor. It has a red motor plug and is tunable up to 50 km/h. If your old controller is faulty or damaged, you replace it with this original part.

You order at FatbikeKlaar.nl; from Belgium you order the same part via FatbikeKlaar.be, and in English you can do so via FatbikeKlaar.com.

Which bike is this controller for?

This controller is intended for the Ouxi Q8. That bike has a 48V / 20Ah / 960Wh battery and reaches up to 90 km on low assistance. It is made for 2 people and carries a maximum of 150 kg. The controller only works in combination with a red motor cable. If you have a different fatbike model, you need a controller that matches that model.

What the controller does

The controller sits between the battery and the motor. It decides how much assistance you get when you pedal or use the throttle. Without a working controller, the Q8 therefore rides like an ordinary, heavy bike.

Specifications at a glance

  • Motor plug: red.
  • Version: 500W.
  • Tunable: up to 50 km/h.
  • Restricted: throttle up to 6 km/h.
  • Cables: 5 connections, with alarm.
  • Model: Ouxi Q8.

Tuning: what is possible and what is allowed

With this controller your Q8 reaches a maximum of 50 km/h. Tuned riding is only allowed on private or enclosed property; on public roads a maximum of 25 km/h pedal assist applies. The tunable Ouxi M5 display (2.0) also fits the Q8. With the kill switch on that display you switch back to 25 km/h before you go onto the road. If you bought the Q8 in the Tunable version, the tuning parts were already included and this controller is a spare part. You can read more about choosing between a controller and a display for Ouxi in tuning the Ouxi V8.

Fitting it yourself

You do not need a workshop to replace the controller. There are only 5 cables to connect.

  • First take the saddle off the Q8, so you can reach the controller properly.
  • Compare the colour of the plug and the number of cables with your old controller.
  • Connect the cables one by one and take a short test ride.
