Fatbike tuning is a popular topic among fatbike enthusiasts. With a tuning kit you get more speed and performance out of your fatbike. Important to know: a tuned fatbike may only be used on private property. With the killswitch function you switch back to the legal 25 km/h in one simple step.

What is a fatbike tuning kit?

A tuning kit is a set of parts that raises the standard top speed of your fatbike. In the factory setting, a fatbike is limited to 25 km/h. With a tuning kit you unlock higher speeds, usually 45 km/h or 50 km/h, depending on the model and kit.

A complete tuning kit usually consists of:

• A tunable display with killswitch function
• A tunable controller with higher current capacity
• Optionally modified controls or wiring harnesses

At FatbikeKlaar.nl you'll find both individual parts and complete sets, tailored to Ouxi and QMWheel models.

Why tune a fatbike?

Many fatbike owners choose to tune their fatbike for more riding fun, better performance on hills and a higher top speed for intensive use on private property. A tuned fatbike often accelerates faster too and delivers a sportier riding experience.

At FatbikeKlaar.nl, tuning is designed as a reversible option: thanks to the killswitch function, you switch the display back to the 25 km/h limit at the push of a button. That way your fatbike can always be set to suit the situation.

Tunable displays with killswitch

The heart of a tuning kit is the tunable display. It replaces the standard display and gives you access to higher speed settings.

How does the killswitch work?

The killswitch is a function that lets you quickly switch the fatbike back to the legal 25 km/h. It usually works by holding down 2 buttons on the display for about 3 seconds. This activates the speed limiter within seconds.

All tunable displays at FatbikeKlaar.nl come with a killswitch. This gives you the freedom to switch flexibly between modes.

Popular tunable displays

The range includes displays for various models:

• Hc80 Display: for Ouxi fatbikes, tunable up to 50 km/h, with and without NFC
• H6c Display: for QMWheel H6C, V20, V20 Pro, S20, V20 Max and V30, tunable up to 45 km/h
• M5 Display: for Ouxi 2.0, tunable up to 50 km/h, with killswitch

Every display is plug & play and easy to replace.

Tunable controllers

Alongside the display, the controller plays a key role in tuning. The controller regulates the current from the battery to the motor. A tunable controller has a higher current capacity (for example 21A) and can therefore drive the motor harder.

Popular tunable controllers:

• C80 Controller (21A): for Ouxi fatbikes, tunable up to 50 km/h
• V20/V20 Pro Controller (21A): for QMWheel models, tunable up to 45 km/h

Controllers often have a red plug for easy identification and are fitted plug & play.

Choosing a tuning kit for your model

Not sure which tuning kit fits your fatbike? For Ouxi models such as the V8, V8 Pro, V8 Max, C80, C80 Pro, C63, H9 and Q8, choose a tunable HC80 or M5 display (up to 50 km/h) or a tunable 21A controller. For the GT2000 there is a separate tunable controller that goes up to 60 km/h. If you ride a QMWheel V20, V20 Pro, V20 Max, S20 or V30, the H6C display (up to 45 km/h) or the matching V20 controller is the right choice. Browse all tunable displays and tunable controllers, or go straight for a complete model from our tunable fatbikes.

Please note: a tuned fatbike is only allowed on private/enclosed property; on public roads a 25 km/h limit applies.
