Ouxi V8 Ultra tunable controller: 50 km/h on private property
The Ouxi V8 Ultra combines a 500W motor with a rotation sensor, NFC locking and a built-in alarm. This controller drives that motor. It has a red motor plug and is tunable up to 50 km/h. Use it to replace a faulty or damaged controller.
You order it at FatbikeKlaar.nl; you order the same part via FatbikeKlaar.be from Belgium and via FatbikeKlaar.com in English.
Which bike is this controller for?
This controller belongs to the Ouxi V8 Ultra. That bike runs on a removable 48V / 15Ah / 720Wh battery and reaches up to 80 km on the lowest assistance. It has front and rear suspension, a long saddle for two people and weighs 40 kg. The V8 Ultra shares its base with the Ouxi V8 Ultra Max, which rides on two batteries. The controller only works with a red motor cable.
What does the controller do?
The controller distributes the power from the battery to the motor. It regulates how much assistance you get based on your pedalling and the throttle. So you notice a faulty controller straight away in how the bike rides.
Features
- Motor plug: red, only for a red motor cable.
- Version: 500W.
- Speed: tunable up to 50 km/h.
- Restricted: throttle up to 6 km/h.
- Connections: 5 cables, with alarm.
Tuning: what is possible and what is allowed
Tuned, the V8 Ultra reaches 50 km/h with this controller. Tuned riding is only allowed on private or enclosed property; on public roads a maximum of 25 km/h pedal assist applies. In the V8 family you tune with a tunable controller or with a tunable display with kill switch. For the V8 Ultra, the tunable M5 display and the tunable HC80 display with NFC are available separately. With the kill switch you set the bike back to 25 km/h. If you bought the Tunable version, the tuning parts were already included and this controller is a spare part. The guide tuning the Ouxi V8 explains the choice between controller and display.
Fitting in a few steps
Replacing the controller is easy: there are only 5 cables.
- Switch the bike off and take the battery out of the frame.
- Take the saddle off the bike, so you can easily reach the controller.
- Connect the 5 cables of the new controller.
- Check that the plug to the motor is red.
