The Ouxi V8, V8 Pro and V8 Max are restricted to 25 km/h as standard. Want to go faster on private or enclosed grounds? Then you tune your V8 by replacing the display or the controller with a tunable version. It hardly gets simpler. In this article you'll see at a glance what you need.
- Every V8, V8 Pro and V8 Max can be tuned to 50 km/h
- Tunable display? M5 or HC80, with or without NFC: they all fit every V8
- Our recommendation: the HC80 with NFC, your fatbike only starts with your NFC card, so extra secure
- Tunable controller? Check the colour of your motor plug first: red fits red, black fits black
- Ordered before 23:59 = delivered tomorrow, free help via WhatsApp
Tuning the display or the controller: what's the difference?
- Display tuning (easiest): new display on the handlebars, plug in, done. You ride up to 50 km/h straight away.
- Controller tuning: new controller in the frame. A bit more wrenching, same result: up to 50 km/h.
Not sure? In our tuning kits collection you'll find both solutions conveniently in one place.
Which display do I choose? (they all fit)
Good news: you don't need to figure anything out. Every V8, V8 Pro and V8 Max works with the M5 and the HC80, with or without NFC. It doesn't matter. The only difference is how you switch the fatbike on:
- HC80 with NFC (our recommendation): your fatbike only starts with the NFC card. Nobody else can switch it on, which helps against theft. And ideal for parents: children can't switch the bike on without the card.
- HC80 without NFC: start with a PIN code.
- M5 display: the newer Ouxi display, also up to 50 km/h.
All tunable displays have a killswitch: one move and you're back at the standard 25 km/h.
Choosing a controller? Check the colour of your motor plug
This is where things most often go wrong in practice, so remember: red fits red, black fits black. Follow the cable that comes out of the motor at the rear wheel and check the colour of the plug:
- Red plug → choose the V8/C80 tunable controller with red plug
- Black plug → choose the V8 tunable controller with black plug
This applies just as much to the V8 Pro and V8 Max. Can't work it out? Send a photo of the plug to our WhatsApp specialist and we'll take a look with you straight away.
Step-by-step: replacing the display
- Take the old display off the handlebars and unclip the plug.
- Fit the new display and connect the plug: it only fits one way.
- Test the fatbike carefully on private grounds. Done!
Step-by-step: replacing the controller
- Switch off the fatbike and remove the battery.
- Open the controller compartment in the frame and first take a photo of all the connections.
- Disconnect the plugs and connect the new controller one-to-one; the plugs only fit one way.
- Battery back in, and test carefully on private grounds.
Always keep your original part. That way you can easily set the fatbike back to 25 km/h later.
