Making your fatbike faster almost always starts with the display. But which tuning display exactly fits your model? The answer depends on your fatbike's brand: QMWheel models work with the H6C display, while Ouxi models have an HC80 or M5 display. In this buying guide, you'll see at a glance which display belongs on your fatbike, the difference between the 25 and 45/50 km/h versions, and which mistakes you'd do well to avoid.
How to determine which display fits your fatbike
The display is the small screen on your handlebars that shows your speed, battery level and assist mode. When derestricting a fatbike, you replace this screen with a tunable version that removes the speed limiter. Important: the display has to match your brand's wiring and controller. In short:
- QMWheel (V20, V20 Pro, S20, V20 Max, V30): H6C display with a 5-pin plug.
- Ouxi (V8, V8 Pro, V8 Max, C80, C80 Pro, C63, H9, Q8): HC80 display, available with and without NFC.
- Ouxi 2.0 models: M5 display.
Buying guide: the right tuning display per model
| Your model | Brand | Standard display | Tunable version |
|---|---|---|---|
| V20, V20 Pro, S20, V20 Max, V30 | QMWheel | H6C (25 km/h) | H6C Tunable Display 45 km/h |
| V8, V8 Pro, V8 Max, C80, C80 Pro, C63, H9, Q8 | Ouxi | HC80 (25 km/h) | HC80 Tunable Display 50 km/h (without NFC) or HC80 Tunable Display NFC 50 km/h |
| Ouxi 2.0 models with M5 display | Ouxi | M5 (25 km/h) | M5 Tunable Display 50 km/h |
| GT2000 | Ouxi | n/a | Tuning is done here via the GT2000 Tunable Controller |
Not sure whether your Ouxi has an HC80 or an M5? Compare the screen on your handlebars with the product photos in our displays collection; the difference is immediately visible. Do you start your Ouxi with an NFC tag or NFC key? Then always choose the NFC version of the HC80 display, otherwise your fatbike won't start anymore.
25 km/h or 45/50 km/h: what's the difference?
Every standard display is limited to 25 km/h. A tunable display removes that limit: the H6C display goes up to 45 km/h, the tunable HC80 and M5 displays up to 50 km/h. A handy feature is the killswitch on the HC80 and M5 versions (the HC80 also comes with code protection): it lets you switch back to the normal 25 km/h mode in a matter of seconds, for example when someone else is riding the bike.
Please note: a derestricted fatbike is only permitted on private or enclosed grounds; on public roads a 25 km/h limit applies.
Common mistakes when choosing a tuning display
- Ordering the wrong brand. An H6C will never fit an Ouxi and an HC80 will never fit a QMWheel; the plugs and software aren't interchangeable.
- Overlooking NFC. If your Ouxi has NFC unlocking, a display without NFC won't work properly. Check this before you order.
- Confusing the HC80 and M5. Newer Ouxi 2.0 models have the M5 display; if you order an HC80, it won't fit.
- Buying a display when your model is tuned via the controller. The GT2000, for example, isn't derestricted via the display but with a tunable controller.
- Not checking the plug. Count the pins on your display plug (the H6C display has a 5-pin connector, for example) and compare with the product description.
Tune the display, or the controller after all?
For most Ouxi and QMWheel models, replacing the display is the simplest way to derestrict: swap the plugs, adjust the settings and you're done. Would you rather tune the controller, or do you have a model where that's the designated route? In our tuning kits collection you'll find all tuning kits neatly organised per model, including tunable controllers.
Frequently asked questions
Can I still just ride at 25 km/h after tuning?
Yes. The tunable HC80 and M5 displays have a killswitch that lets you easily switch back to the standard 25 km/h mode; the HC80 also works with a security code. That way, you decide when to use the extra speed — on private grounds only, of course.
Do I also need to replace the controller as well as the display?
Usually not: for most Ouxi and QMWheel models a tunable display is enough. Only on certain models, such as the GT2000, does tuning go via the controller. If in doubt, send us a quick message via WhatsApp.
How do I know if my Ouxi has NFC?
Do you start the fatbike by holding a tag, card or keyring against the display or the NFC sticker? Then you have NFC and you should choose the NFC version of the tunable HC80 display.
