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.
You have questions, we have answers!
Why choose fatbikeklaar.nl?
We specialize in tunable fatbikes and parts. Over 500 happy customers have gone before you. Fast delivery, sharp prices, and customer service that truly thinks along with you.
Can I have my fatbike tuned by you?
Our fatbikes are tunable, and we also supply individual parts to upgrade your fatbike. Please note: tuning is only permitted on private property, not on public roads.
Is a fatbike still legal?
Yes, a fatbike that complies with current regulations (max. 25 km/h pedal assist and a 250W motor) is fully legal on public roads. Tuned models may only be used on private property.
What are the new fatbike rules for 2026?
As of 2026, stricter rules apply around age, helmet requirements, and vehicle specifications. Check our information page for the latest details.
Do you need a driver’s license for a fatbike?
You don’t need a driver’s license for a regular fatbike with pedal assist up to 25 km/h. You do for tuned models above that limit. Keep in mind those are only allowed on private property.
Why buy a fatbike?
A fatbike is comfortable, fast, and ready for any terrain, from city streets to the beach. Ideal for commuting and for fun. And with our tunable models, you get even more out of it.
Do you need a helmet on a fatbike?
A helmet is strongly recommended for your own safety. From 2026, a helmet requirement will be introduced for certain fatbike categories.
Can I derestrict my QMWheel V20 Cross?
Yes. With the derestrictable controller with the red motor plug (21A, 500W) your V20 Cross goes up to 45 km/h instead of 25 km/h. The plugs fit the original wiring exactly, so you can install it yourself. Riding derestricted is only allowed on private property.
How fast does a derestricted V20 Cross go?
With the derestrictable controller the V20 Cross reaches up to 45 km/h. As standard it is limited to 25 km/h pedal assist. Riding above 25 km/h is only allowed on private property, not on public roads.
How fast does the Ouxi GT2000 go when derestricted?
Derestricted, the GT2000 reaches up to 60 km/h, both on the throttle and on the pedal assist. Limited, it does 6 km/h on the throttle and 25 km/h on the pedal assist. The derestricted mode is intended for private property.
What does the kill switch on the GT2000 do?
The kill switch lets you switch between limited and derestricted riding yourself. It is included as standard, so there is nothing extra to order. Only switch it over on private property.
What does derestricting a fatbike cost?
A derestrictable controller costs from 98 euro for the V20 family and the Ouxi models, and 179 euro for the GT2000. Fitting it yourself usually takes less than half an hour. Not sure which part fits your fatbike?
Can I tune an Ouxi C80 Mini or QMWheel V20 Mini?
No. The Ouxi C80 Mini, C63 Mini and the QMWheel V20 Mini cannot be tuned. There is no tunable controller or tunable display for these models; they stay limited to 25 km/h. Do you want to tune after all? Then have a look at the Ouxi C80, V8 or GT2000 and the QMWheel V20 or V20 Pro.
