This tutorial only applies in particular to the QS-S4 ZERO LCD throttle. You may not need to replace the whole throttle in case it is broken. We do have spare throttle levers as a spare part too.
Here are the extent of the settings: 1. P01 - LCD brightness level (1, 2, 3) 2. P02 - Mileage display in km or miles 3. P03 - Voltage level of machine (24, 36, 48, 52, 60V) 4. P04 - 1-60 mins before machine goes to sleep with inactivity 5. P05 - N/A 6. P06 - Wheel diameter in inches 7. P07 - No. of magnets on motor (Default 30) 8. P08 - Power Level (0-100) 9. P09 - Zero start or kickstart 10. P10 - N/A 11. P11 - Electronic braking on or off 12. P12 - Soft or high acceleration (1 is softest start; 5 is highest torque) 13. P13 and P14 - N/A 14. P15 - Controller cutoff voltage 15. P16 - Zero-ing of ODO 16. P17 - cruise mode 17. P18 to P20 - N/A
Fault Codes (see video on how to resolve the fault codes) 2 - brake 4 - 6kmh cruise 6 - battery undervoltage 7 - motor faulty 8 - throttle faulty 9 - controller faulty 10 - faulty comms between controller and LCD 11 - faulty comms between controller and LCD 12 - BMS failure 13 - headlight failure

Thumb Throttle Option
We have also made a custom thumb throttle option that will be easier to throttle for some users. There is finer control with thumb throttles.
This works the same way as the stock ZERO QS-S4 throttle except the throttle lever is pushed by the thumb instead of being triggered by the fore finger.
Together with the ZERO LCD, we provide 2 different integrated locking system: the ordinary key lock and the biometric fingerprint lock.
The key lock comes with 2 spare keys for you while the finger print lock enables 14 different fingerprints to be stored so you can pass on the ebike or e-scooter to be used by anyone of your choosing.
For both locking systems, the LCD will not be activated if the key or the fingerprint locks are not unlocked.
