Description
36V/48V Bike Controller Kits with S866 Display and 6 magnets pedaling sensor

Display cable: Red: VCC/Blue: K/Black:GND/Green: RX/Yellow: TX

P01： Backlight brightness, level 1 is the darkest, level 3 is the brightest;

P02: Unit of mileage, 0: KM; 1: MILE;

P03: Voltage level: 24 V, 36 V, 48 V, 60 V, 64 V, default 36 V;

P04: Turn off my display after: 0, no sleep; other numbers are sleep time, range: 1-60; unit: minutes;

P05: Pedaling gear: 0-speed mode, 3-speed/1 mode, 5-speed mode

P06: Wheel diameter: unit, inch; accuracy: 0.1;
This parameter is related to the display speed of the instrument and must be entered correctly;

P07: Speed measurement magnet number: Range: 1-100;
This parameter is related to the display speed of the instrument and must be entered correctly;
If it is a common hub motor, directly enter the number of magnetic steels;
If it is a high-speed motor, it is also necessary to calculate the reduction ratio, input data = number of magnets × reduction ratio;
For example: the number of magnets in the motor is 20 and the reduction ratio is 4.3: the input data is: 86 = 20 × 4.3.

P08: Speed limit: range 0-100 km/h, 100 means no speed limit,
The input data indicates the maximum operating speed of the vehicle. For example, if you enter 25, it means that the maximum operating speed of the vehicle will not exceed 25 km/h. The driving speed is kept at the set value.

Error: ±1 km/h; (both power assist and handlebar speed limit)
Note: The value here is based on kilometers. When the unit setting is changed from kilometers to miles, the speed value in the display interface will automatically convert to the correct value in miles, but the speed limit value set in this menu in the miles interface will not convert and will be inconsistent with the speed limit value in miles that is actually displayed.
Note: Menu P09-P15 is only valid in communication state
P09: Zero start, non-zero start setting, 0: zero start; 1: non-zero start;
P10: Riding mode setting 0: pedal assist riding (power output is determined by the position of the power assist gear and the handlebar is not valid at this time).
1: Electric drive (handlebar operated, electric assist position is not valid at this time).
2: Paddle and electric propulsion co-exist

P11: Electric assist sensitivity setting range: 1-24;
P12: Assisted start current setting range: 0-5;
P13: Configuration of magnetic assisted steel plate type: 5, 8, 12 magnetic steel three types
P14: Controller current limit value setting Default 12 A Range: 1-20 A
P15: Undervoltage value of the controller
P16: ODO restart setting Press and hold the up button for 5 seconds to restart ODO
P17: 0: Disable cruise/1: Enable cruise; automatic cruise is optional (valid for protocol 2 only)
P18: Display speed ratio adjustment range: 50% ~ 150%,
P19: 0 gears enable bit, 0: includes 0 gears, 1: excludes 0 gears
P20: 0: Protocol 2/ 1: Protocol 5S /: Reserve 3: Reserve
