Description:
Ultra-quiet, motor torque ripple is minimized to achieve no noise, no vibration and comfortable operation.Based on the Field Oriented Control (FOC) algorithm, the controller has high conversion efficiency, which can effectively reduce controller temperature rise and extend battery life.

Features:
1. Power on/off: Long press to power on, long press to power off.
2. Riding mode: non-zero start mode (that is, press the accelerator to start when the coasting speed reaches 3KM/H); zero start mode (turn the acceleration bar to start the motor in a stationary state).
3. Speed gear: 1st gear 10KM/H, 2nd gear 20KM/H, 3rd gear 25KM/H. Click to switch gears (with memory function, the default is the gear used before the last shutdown).
4. Electronic brake: compatible with power-off brake and linear Hall brake.
5. Tail light: the light is always on and the brake flashes.
6. Cruise mode:
(1). Turn on the cruise control function: In riding mode, press the accelerator speed control and enter the cruise mode automatically after 10 seconds after the speed control stabilizes. (Press the brake, accelerator, switch gears, all can exit cruise mode).
(2). Constant speed cruise function off: never enter cruise during riding.
7. Memory mode: Power on for the first time, run at no-load speed regulation and keep the handle for 3 seconds. After releasing the handle for 5 seconds, the motor drive can automatically learn and save the motor parameters.
8. MOS tube breakdown protection: Before the controller is powered on or in operation, if the D and S poles of the upper or lower arm of the MOS tube of one phase are short-circuited, the controller will stop driving without output. It can work normally only after troubleshooting.

Power Display:
(1)Voltage 38.2V-42V The first second third fourth fifth lights are always on.
(2) Voltage 36.6V-38.2V The first second third fourth light is always on
(3) Voltage 34.5V-36.6V The first second third lights are always on
(4) Voltage 32.8V-34.5V The first second light is always on
(5)Voltage 31.5V-32.8V The first light is always on
(6)Voltage 30-31.5V The last grid flashes
(7)Turn-off of motor with voltage below 31V

Error Code & Solution:
(1) "E1" Motor Hall failure
Solution: Adjust the yellow, green and blue hall line.
(2) "E2" MOS fault or motor phase line short circuit fault
Solution: Check the connection of the wires.
(3) "E3" Brake failure
Solution: Check the connection of the wires.
(4) "E4" Handlebar failure
Solution: Turn the speed control handle for several times and check the connection of the wires.
(5) "E5" Undervoltage protection
Solution: Check or replace the batteries.
(6) "E6" Instrument/control communication failure
Solution: Check the connection of the wires.
(7) "E7" Overvoltage protection
Solution: Check or replace the batteries.
(8) "E8" Controller op amp failure
Solution: Check the connection of the wires.
(9) "E9" Stall protection
Note: Please don’t worry if there is an error code, it is because your cable is connected incorrectly, not the product has a problem, then you need to re-understand how the cable is connected.

Cable Description:
Headlight------Red+Black Line
Accelerator------Black+Green+Red Line
Communication Line------Round Port
Taillight------Red+Black Line
Communication Line-----Green+Blue+Black+Red+Yellow Line
Burn Line-----This Red +Green+ Black Line is the burn line,you can ignore it, this line has no effect on installation.
To connect the two ports, make sure that the colors of the connected wires are the same.
The taillights need to be connected to the controller; the headlights need to be connected to the meter.
