Settings

P01: Backlight brightness, level 1 is the darkest and level 3 is the brightest;
P02: Mileage unit, 0: KM; 1: MILE;
P03: Voltage level: 24V, 36V, 48V, default 36V;
P04: Sleep time: 0, no sleep; Other numbers refer to sleep time, ranging from 1 to  60; Unit minute;
PO5: Power assisted gear: 0, 3rd gear mode: 1st gear 2V, 2nd gear, 3V, 3rd gear, 4V; 1st and 5th gear modes: 1st gear 2V, 2nd gear 2.5V, 3rd gear 3V,4th gear, 3.5V,  5th gear, 4V;
P06: Wheel diameter: unit, inch; Accuracy: 0.1;
P07: Speed measurement magnetic steel number: range: 1-100;
P08: Speed limit: Range 0-50km/h, where 50 indicates no speed limit,
1. Non communication state (instrument control): When the speed is greater than the set speed, the PWM output is turned off; When the speed drops below the set speed, the PWM output is automatically turned on, and the driving speed is + 1km/h of the current speed; (Only for power  assisted speed limit, no speed limit for the handlebar)
2. Communication status (controller control): The driving speed is maintained at the set value, with an error of + 1km/h; (Speed limit for power assistance and rotating handle) Note: The value here is based on kilometers. When the unit setting is converted from kilometers to miles, the speed value on the display interface will automatically be converted to the correct mile value. However, the speed limit data set in this menu under the mile interface will not be converted, which is inconsistent with the actual displayed mile speed limit value;
PO9: Zero start and non zero start settings, 0: Zero start; 1: Non zero start;
P10: Drive mode setting 0: Power assisted drive (how much power is output is determined by the power assisted gear, at this time The transfer handle is invalid.
1: Electric drive (driven by a rotating handle, at which point the assist gear is invalid).
2: Assisted drive and electric drive coexist simultaneously (invalid in zero start state of electric drive).
P11: Assist sensitivity setting range: 1-24;
P12: Power start intensity setting range: 0-5;
P13: Three types of magnetic steel discs for assistance: 5, 8, and 12 magnetic steel discs
P14: Controller current limit setting default 12A range: 1-20A
P15: Function not yet activated
P16: ODO reset setting: Press and hold the up button for 5 seconds to reset ODO
