You have questions, we have answers!
Everything you want to know about fatbikes, tuning and our service.
What is the difference between a restricted and a tunable controller?
The difference is in the software, not in the number of amps. The speed limit is set in the controller's software. A tunable controller has software that allows more speed, intended for private property only. Which controller fits depends on your model and the colour of your motor plug: red fits red, black fits black. Not sure? Send a photo of your plug via WhatsApp.
Do you test the parts before shipping?
Yes. Every tunable display and every controller is tested on a fatbike by our specialist in our workshop in Amsterdam before it leaves: connecting, tuning and switching back.
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.
What does tuning a fatbike cost?
A tunable controller costs from 98 euro for the V20 family and the Ouxi models, and 179 euro for the GT2000 and GT2000 2.0. Fitting it yourself usually takes less than half an hour. Not sure which part fits your fatbike?
