Are you looking for a way to tune your fatbike? At FatbikeKlaar.nl you'll find a complete range of tuning kits, tunable displays, and tunable controllers for Ouxi and QMWheel fatbikes. Whether you want to go up to 45 km/h or 50 km/h: here you'll find the right parts for your model, including a killswitch function for flexible use.

Fatbike tuning is a popular topic among fatbike enthusiasts. With a tuning kit, you get more speed and performance from your fatbike. Important to know: the use of a tuned fatbike is only allowed on private property. With the killswitch function, you can switch back to the legal 25 km/h with a single action.

What is a fatbike tuning kit?

A tuning kit is a set of parts that increases the standard maximum speed of your fatbike. In the standard 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
• Possibly customized 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 pleasure, better performance on hills, and a higher top speed for intensive use on private property. A tuned fatbike often also responds faster when accelerating and provides a sportier riding experience.

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

Tunable displays with killswitch

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

How does the killswitch work?

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

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

Popular tunable displays

The assortment 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

Each display is plug & play and easy to replace.

Tunable controllers

In addition to 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 (e.g., 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 mounted plug & play.
