Before you change anything
⚠ Read this page fully first. Two parameters — P03 (voltage) and P14 (current limit) — can damage the battery, controller and motor if set outside specification. Damage caused by out-of-spec parameter values is not covered by warranty. See Warranty Claims.
Write down the current value of any parameter before you change it.
The parameters
| Parameter | Setting | Notes |
|---|---|---|
| P01 | Display brightness / backlight | Cosmetic |
| P02 | Speed unit — 0 = KM/H, 1 = MPH |
See Changing the Speed Unit |
| P03 | Voltage level | Must match your pack — 36V / 48V / 72V. Wrong value = real faults |
| P04 | Dormancy / sleep timer | Minutes before the display sleeps |
| P05 | Backlight brightness | Cosmetic |
| P06 | Wheel diameter | Affects speedo accuracy |
| P07 | Speed signal magnets | 1–255. Wrong value makes the speedo read wrong |
| P08 | Speed limit | 0–100 km/h. 0 = no limit |
| P09 | Zero-start / non-zero-start | Whether the throttle works from a standstill |
| P10 | Drive mode | 0 = power, 1 = electric, 2 = coexist (pedal + motor) |
| P11 | Assist sensitivity | 1–24 |
| P12 | Start intensity | 0–5. How hard the motor comes in from a stop |
| P13 | Magnet disk count | 5 / 8 / 12 — must match the PAS disk fitted |
| P14 | Controller current limit | Default 12 A, range 1–20 A. Above specification damages the controller and motor |
| P15 | Undervoltage threshold | Protects the pack from over-discharge. Do not lower this to chase range |
| P16 | ODO reset | Long-press up for ~5 seconds to clear |
| P17 | Cruise control | On/off |
The three that actually matter
- P03 voltage. Set it to the wrong level and the controller misreads the pack state — producing low-voltage and charging faults that look like hardware failures.
- P14 current limit. Raising it beyond specification is the fastest way to destroy a controller and motor. It is not a safe "free power" upgrade.
- P15 undervoltage. Lowering it to squeeze out more range deep-discharges the pack, which shortens its life. The protection is there for a reason.
