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.

Does it fit your fatbike?

This controller is intended for the Ouxi GT20 and only works in combination with a red motor cable. Before you order, compare the colour of the plug and the number of connections with your own controller. Do you have another model? On our site you will find the right controller for your fatbike.

Fitting it yourself

Fitting a new controller is really quite simple: there are only 5 cables you need to connect. Take the battery out of the bike first and take a photo of the old connections. Still not working out? Just message us on WhatsApp at 06 82090642 and we will help you quickly.

Riding tuned is only allowed on private property. On public roads 25 km/h remains the limit.

Important: this controller is intended for the Ouxi GT20 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 GT20 - Tunable Controller: red motor plug, up to 50 km/h on private property

The Ouxi GT20 - Tunable Controller is the separate controller for the Ouxi GT20, the 20-inch fatbike for two people with a suspension fork. It drives the motor, has a red motor plug and 5 connections without alarm. You use it to replace a faulty controller, or to let the GT20 ride up to 50 km/h on private property.

You order this controller at FatbikeKlaar.nl; the same part is also available on FatbikeKlaar.be for Belgium and in English on FatbikeKlaar.com.

Which bike is this controller for?

The Ouxi GT20 rides on 20-inch wheels and has a removable 48V / 15Ah / 720Wh battery. It charges fully in about 4 hours and is good for a range of up to 65 km. The bike has a suspension fork, is suitable for 2 people and weighs 43 kg. Braking is done with hydraulic disc brakes, shifting with Shimano 7 gears.

Check two things before you order:

  • Plug colour: the cable to the motor has a red plug. With a different colour this controller will not work.
  • Connections: your current controller has 5 cables and no alarm connection.

In doubt? Take a photo of your old controller and send it via WhatsApp to 06 82090642.

What the controller does

The controller is the link between battery, motor, display and throttle. It decides how much power the motor gets and up to which speed the motor assists.

  • Motor plug: red, for the motor cable of the GT20.
  • Version: 500W.
  • Connections: 5 cables, without alarm.
  • Restricted: in the restricted setting the throttle works up to 6 km/h.
  • Tunable: up to 50 km/h, only on private or enclosed property.

Tuning: what is possible and what is allowed

With this controller the GT20 reaches up to 50 km/h when tuned. In the restricted setting the pedal assist stays at 25 km/h and the throttle works up to 6 km/h.

Riding tuned is only allowed on private or enclosed property; on the public road a maximum of 25 km/h pedal assist applies.

You will find more parts for tuning among the tuning kits. How tuning works in general is explained in Fatbike tuning: the complete guide.

Fitting: replacing the controller yourself

Replacing a controller is not a big job: you disconnect 5 cables and connect them again. This is how you do it:

  • Battery out: remove the battery from the bike before you disconnect any cables.
  • Take a photo: photograph how the plugs are connected now.
  • Old controller off: disconnect the cables one by one.
  • New controller on: connect each cable in the same place.
  • Test: put the battery back and check the display, motor and throttle.

Not working out? Message us on WhatsApp at 06 82090642 and we will look at it with you.

Frequently asked questions about the Ouxi GT20 controller

Does this controller also fit the GT16 or GT24?

We list this controller for the Ouxi GT20. If you ride a GT16, GT20 Pro or GT24, choose the controller listed for that model. For every model, check the red motor plug and the 5 connections.

How fast does the GT20 go with this controller?

Tuned up to 50 km/h. In the restricted setting the pedal assist is 25 km/h and the throttle works up to 6 km/h. Riding tuned is only allowed on private or enclosed property.

Can I fit the controller myself?

Yes, you connect 5 cables. Take the battery out of the bike first and take a photo of the old connections. If you get stuck, message 06 82090642.

Do I need a driving licence if I tune the GT20?
