Fatbike tuning is one of the questions our WhatsApp specialists get asked most. In this 2026 guide you'll see in a few minutes how it works, what you need for your model and what to look out for.
- Tuning = replacing one part: the display or the controller
- Ouxi V8 and C80 models: up to 50 km/h · QMWheel V20 series: up to 45 km/h · GT2000: up to 60 km/h
- No software hack or shady app: just a physical part you fit yourself
- Only for private or enclosed grounds; on public roads 25 km/h applies
- Ordered before 23:59 = delivered tomorrow, with up to 3 years of warranty
What is fatbike tuning?
Every fatbike sold as an e-bike is restricted to 25 km/h as standard. That limiter isn't in the motor, but in the electronics. By replacing the display or the controller with a tunable version, you remove that limiter. After that, depending on your model, you ride at 45 to 60 km/h.
Two routes: display or controller
- Display tuning (easiest): replace the small screen on your handlebars. Old one off, new one on, plug in: done within fifteen minutes. The most popular choice for Ouxi (HC80 or M5, 50 km/h) and QMWheel (H6C, 45 km/h).
- Controller tuning: replace the box that drives the motor. A bit more wrenching, and your fatbike also accelerates more briskly. Always check the colour of your motor plug first: red fits red, black fits black.
Which fatbikes can be tuned?
- Ouxi V8, V8 Pro, V8 Max: via the HC80 or M5 display (up to 50 km/h, with or without NFC: they all fit) or via a tunable controller.
- Ouxi C80, C80 Pro, C63, H9, Q8: via the HC80 display (up to 50 km/h) or a tunable controller.
- Ouxi GT2000: via the special tunable controller, up to 60 km/h.
- QMWheel V20, V20 Pro, V20 Max, S20, V30: via the H6C display (45 km/h) or a tunable V20 controller.

What does tuning a fatbike cost?
A tuning kit is far cheaper than a new, faster fatbike. You'll find the current prices in our tuning kits collection. Ordered before 23:59 = delivered tomorrow.
How difficult is the installation?
Replacing a display is plug-and-play: usually all you need is an Allen key. Replacing a controller takes a little more patience: photograph the cables beforehand and move the plugs over one by one. They only fit one way. If you get stuck, our specialist will help you step by step via WhatsApp.
Frequently asked questions about fatbike tuning
How fast does a tuned fatbike go?
Ouxi models reach up to 50 km/h with a tunable display, QMWheel models up to 45 km/h, and the GT2000 reaches up to 60 km/h with a tunable controller.
Can I tune my fatbike myself?
Yes. Almost anyone can replace a display; replacing a controller takes a little more skill. Our WhatsApp specialist helps you free of charge with choosing and fitting.
Do I keep my warranty after tuning?
The tunable displays and controllers themselves come with up to 3 years of warranty from us. Do bear in mind that modifying your fatbike may affect the manufacturer's warranty on the bike itself.
