Encoder calibration has to be performed each time: you replaced MC, replaced encoder or removed encoder disc for cleaning.

Note: Encoder calibration and / or motor phase check must be done with rear wheel elevated - OFF ground. You should use stable scissor jack or other bike lift. It is possible to make the calibration on the ceterstand (we don't reccomend it) - but you have to be sure that during the process rear wheel does NOT touch the ground.


A. Using Vectrixdiagnostics application (if you don't have diagnostic cable - scroll down to section B)

1. Using scissor jack elevate the rear wheel, check the stability of bike.

2. Fold (close up) the sidestand / kickstand

3. Connect diagnostic cable to the scooter

4. Turn ignition ON

5. Press the Kill Switch to RUN position (as you would do riding bike).

6. Open Vectrixdiagnostics application

7. Set the right mode (VX-1 Ni / VX-1 Li), make sure CAN Bus field is green (communication active)

9. Go to the "ENCODER" page


10. Press the "Check Phase Rotation" button

11. Accept the warning pup-up



12. Observe the rear wheel - it should slowly rotate forward. If rotates backward the motorcontroller - motor cables are not connected properly (3 phase cables, marked A,B,C)


13. Press "Read" button to see current off-set. You will be able to compare if calibration changed.

14. Press "CALIBRATE" button to calibrate encoder - rear wheel will slowly rotate (after few second) and the red indicator on the scale will move from zero to some value below 360.


15. If the calibration exceed 360 or doesn't stop at all - you have to clean or replace encoder.


B. Without Vectrixdiagnostics application

Encoder Calibration

1. Using scissor jack elevate the rear wheel, check the stability of bike.

2. Fold (close up) the side-stand / kickstand

3. Make sure ignition key in in OFF position

4. Press Kill Switch to RUN position

5. With right hand turn fully the throttle, press and hold right brake level.

6. While holding - turn the ignition ON.

7. Wait till dashboard activates, and the "WRENCH" icon / tale-light stays ON - release the throttle and brake.

8. Calibration process will start automatically - wheel start rotating, speedometer needle will rise up from 0kmh to 120kmh and then back to zero.

9 After few seconds "WRENCH" icon will disappear. Calibration is done.-
Note: be careful bike is still in GO mode. Turning throttle will activate motor.

10. If the process repeats by itself again and again - encoder can't find right calibration - requires inspection, cleaning or replacement.

Thank you very much Piotr, It's a very good idea this topic. Have you all documents that we could be found on the site vectrixservice.com ?


Best regards.

Yes, I have all which was on the vectrixservice.com, but only in English. I'm trying to get the other languages.

I can send you all of my documentation in french


Best regards

Yes, please, it will be very helpful. Thank you :)

Tell me if you can download all documents?

Hey Armand,

Yes, we managed to download all as .zip. thank you :)
