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 black 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.

Good, but

Handy that it says which plug it is. The zip ties included were rather thin.

Product information

The benefits at a glance

  • Restricted to 25 km/h
  • 6 km/h throttle
  • Original part
  • Suitable for: QMWheel V20, V20 Pro and S20 with black motor cable
  • Version: 15A, 250W, black motor plug, five connections
  • Speed: limited to 25 km/h, walk assist 6 km/h, cannot be tuned

The 15A controller belongs to the V20, V20 Pro and S20 with the small 250W motor, recognisable by the black motor plug. It replaces a faulty controller without changing anything about the speed: 25 km/h on the road and 6 km/h with the throttle as walk assist.

If there is a red plug on your motor cable, you need the 21A version; this black version does not fit there. If you want to tune the small motor, go for the tunable black plug controller that goes up to 32 km/h. Replacing: remove the saddle, swap five plugs, done in fifteen minutes.

Good to know

The controller is the brain of your fatbike and drives the motor. Before replacing it, first take a photo of the old wiring, so you can later reconnect all the plugs in the right place. Work calmly and make sure the battery is disconnected before you start. Cannot manage it yourself or in doubt? Message us on WhatsApp at +31 6 82090642 and we will help you out quickly.

Pro tip: lay the new controller next to the old one and compare the plugs one by one, so you can be sure everything matches before you connect it.

Software

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