The P2 Parameter is a setting mode for wheel speed pulse signal. If wheel generated 1
pulse signal by a revolution, the P2 value should be set to 1. If the wheel generated 6 pulse
signals by a revolution, P2 should be set as 6. If users did not configure the Parameter then
P2 can be set to 0. The selection of P2 values ranges from 0 to 6.
P3 Throttle Assist Level Control Setting
The P3 Parameter setting will display on the LCD after the P2 Parameter setting has been
selected and confirmed. The KT-LCD3 will display as follows:
P3 Display
P3 Parameters affect the pedal assist system (PAS) control setting. When the value is set
to 0, the throttle is dependent on the PAS level ratio. This means when the PAS level ratio
is 1, the throttle will provide the least amount of power, whereas when it is 5, the throttle will
provide the most power. If the P3 Parameter is set to 1, the throttle independent from assist
levels and will provide maximum power regardless of the PAS level chosen.
P4 Throttle Activation Setting
The P4 Parameter setting will display on the LCD after the P3 Parameter setting has been
selected and confirmed. The KT-LCD3 will display as follows:
P4 Display

The P4 settings is for controlling the throttle activation. When the P4 Parameter is 1, the
throttle is under "delayed startup” where the throttle will only activate the motor after the
motor has been activated via Pedal Assist System. Setting the P4 to 0 will set the throttle
to activate the motor when triggered.
P5 Power Monitoring Setting
The P5 Parameter setting will display on the LCD after the P4 Parameter setting has been
selected and confirmed. The KT-LCD3 will display as follows:
P5 Display
The P5 Parameter is power monitoring mode. When the value is set to 0, the power
monitoring is in "real-time voltage" mode where the method to determine the battery
capacity is based on real-time voltage. Once the P5 Parameter is set to a specified value,
the power monitoring is in "smart power" mode where the value set is determined by the
battery characteristics. Such that, 24V lithium batteries are typically set between 4-11, 36V
lithium batteries set between 5-15 and 48V lithium batteries set between 12-20. The P5
Parameter setting ranges from 0-40.
C PARAMETER SETTING
Enter the C Parameter settings by cycling through the P Parameter Settings to the end
(when display ceases flashing) and simultaneously holding button and button
for 3 seconds. If required to exit at any Parameter, hold button for 2 seconds. Use
the button and button to select the value and confirm selection by pressing
the button. The Parameter will be confirmed and the LCD will enter the following C
