For the red motor plug
Wrong colour? Then the plug won't fit.
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.
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
- Restricted to 25 km/h
- 6 km/h throttle
- Original part
- Suitable for: Ouxi Q8 with red motor cable
- Version: 21A, 250W, red motor plug, 5 cables with alarm connector
- Speed: limited to 25 km/h, throttle up to 6 km/h; tuning is only possible with the separate Q8 tuning controller
Original limited controller for the Ouxi Q8 with red motor plug. If your Q8 shows error codes or no longer provides any assistance, this part puts it back to the standard 25 km/h with 6 km/h walk assist.
For tuning there is the separate tunable Q8 controller; this limited version stays at 25 km/h. The Q8 2.0 with M5 display and the Q9 use a different controller, so check the type plate carefully. Replacing: remove the saddle, transfer five plugs, no tools needed.
Good to know
The controller drives the motor of your fatbike. Before replacing it, first take a photo of how all the plugs are positioned, then disconnect the old controller and connect the new one in exactly the same way. Pay attention to the color and shape of each plug so everything ends up in the right place. Can't manage it yourself or in doubt? Feel free to message us on WhatsApp at +31 6 82090642, and we'll help you out quickly.
Pro tip: place the new controller in the same dry spot as the old one and make sure the connections are firmly secured, this way you prevent failures from moisture or a loose plug.

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