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.

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.

How fast does the Ouxi GT2000 go when tuned?

Tuned, the GT2000 reaches up to 60 km/h, both on the throttle and on the pedal assist. Restricted, it does 6 km/h on the throttle and 25 km/h on the pedal assist. The tuned mode is intended for private property.

What does the kill switch on the GT2000 do?

The kill switch lets you switch between restricted and tuned riding yourself. It is included as standard, so there is nothing extra to order. Only switch it over on private property.

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. Fitting it yourself usually takes less than half an hour. Not sure which part fits your fatbike?

Ouxi GT2000 2.0 – Black: extra lock, OUXI app and the same 1440 Wh battery

The Ouxi GT2000 2.0 in black is the second generation of the GT2000. The figures stay the same: a 48 V / 30 Ah battery with 1440 Wh, 24 inch off-road tyres, hydraulic disc brakes and a 150 kg maximum load. What has been added is in security and electronics: an extra lock at the rear and a matching OUXI app. You choose yourself between Restricted (250W) and Tunable, and between delivery boxed or assembled. You order from FatbikeKlaar.nl; for Belgium the same bike is on FatbikeKlaar.be and in English on FatbikeKlaar.com.

What is new compared with the first GT2000

Rear lock: an extra lock at the rear of the bike, which you use to secure it when you park it.
OUXI app: a free app with the bike, showing among other things the location of your fatbike, your ride data and settings from your phone.
Updated display: a more modern display that shows speed, battery level and ride information more clearly.

According to the manufacturer the app also comes with a built-in tracker and an alarm function; exactly which functions you see can differ per version. Just as important is what does not change: the same motor, the same 1440 Wh battery, the same hydraulic disc brakes, the same 24 inch tyres and the same weight of 34 kg. Anyone who knows the GT2000 rides the 2.0 straight away the way they are used to.

Specifications at a glance

Motor: 250 W, pedal assist up to 25 km/h in the restricted mode.
Battery: 48 V / 30 Ah, 1440 Wh together; charging takes 5 to 6 hours.
Range: 80 km on average, up to 100 km on low assist, around 60 km on high.
Frame and tyres: 24 inch off-road tyres, frame size 85 cm, high step-through, own weight 34 kg.
Load: maximum 150 kg, intended for a rider of 150 to 200 cm.

Tuning: what is possible and what is allowed

If you choose Tunable, the controller, the 6 km/h throttle and the killswitch are already fitted. With that killswitch you switch the bike over yourself: restricted means a throttle up to 6 km/h and pedal assist up to 25 km/h, tuned means throttle and pedal assist up to 60 km/h. Riding tuned is only permitted on private or closed-off property; on public roads pedal assist up to 25 km/h is the maximum, so always set the killswitch to restricted there. If you chose Restricted (250W), you can still fit the separate GT2000 controller later; more options are at tuning kits and the explanation in tuning the GT2000.

Parts, service and warranty

You get 3 years of warranty on the frame and 1 year on the battery and moving parts. Parts for the GT2000 fit the 2.0 in most cases; the display and the electronics around the new lock are the exception, so ask first if you are in doubt. Also have a look at chargers, inner tubes and locks if you want to secure the bike extra well. If you choose delivery boxed, you assemble it yourself; with assembled we build it ready to ride.

Ordering the GT2000 2.0 from FatbikeKlaar

If you are hesitating between models, the product finder sets out the differences; all other models are at fatbikes and questions about delivery, warranty and returns at the frequently asked questions.

Frequently asked questions about the GT2000 2.0

What is the difference with the standard GT2000?

The 2.0 has an extra lock at the rear, a matching OUXI app and an updated display. Motor, battery, brakes, suspension and tyres have stayed the same.

Do I need a driving licence or a helmet?

No. In the restricted mode the bike counts as an electric bicycle with pedal assist up to 25 km/h: no driving licence, helmet requirement or registration plate. Riding tuned is only allowed on private or closed-off property.

How far do I get on the battery?

Count on 80 km with average assist, up to 100 km on low and around 60 km on high assist. A full charge takes 5 to 6 hours.

Does the lock work together with the app?

The lock at the rear is a lock on the bike itself; the app is mainly intended for the location, the ride data and the settings. Exactly which functions you see can differ per version and firmware version.
