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.
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 45 km/h
- Restricted: 6 km/h throttle
- 5 cables, without alarm
- Suitable for: QMWheel V29 Pro (dual battery model) with red motor cable
- Version: 21A, 500W, red motor plug, 5 connection cables without alarm
- Speed: tuned up to 45 km/h on private terrain, delivered limited to 25 km/h
The V29 Pro rides on 29 inch wheels and two batteries, but uses the same motor control as the V20 series. This tunable controller with red motor plug replaces the original one to one and works together with the H6C display with killswitch; with that display you choose between 25 and 45 km/h yourself.
Before you order, check that the plug on your motor cable is red: a black plug does not fit this model. The replacement itself is a job of five plugs, with no tools other than a pair of cutters for the cable ties. Keep the V29 Pro off public roads when tuned; there 25 km/h remains the limit.
Fitting a new controller is actually very simple: there are only 5 cables you need to connect. Still not working out? Just message us on WhatsApp at 06 82090642 and we will help you out quickly.
Pro tip: take the saddle off the bike first, that way you can easily reach the controller to replace it.
WhatsApp chat only. We can't take calls, not even via WhatsApp.
Important: this controller is intended for the QMWheel V29 Pro 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.
Difference between restricted and tunable: it is in the software, not in the number of amps.
