RESETTING THE TRIP COUNTER
The LCD display has a trip counter function to keep track of the
distance of your ride over time. The Amp-hours (Ah) and Watt-
hour (Wh) drawn from the battery pack are also linked to the
trip counter data. You can reset the trip data to zero at any time.
TO RESET THE TRIP, AH, AND WH COUNTER TO ZERO
Push and hold both the power button and “assist down” button
for 3 seconds, then release both buttons. The trip and Ah
counter will reset to zero.
ACTIVATING THE ADVANCE DISPLAY SCREEN
Fig. 28 - Data on the Advanced Display Screen
In some instances it is useful to see additional ride statistics.
The display can be switched into the advanced display mode.
This function will allow you to see expanded real-time data on
one screen.
THIS DATA INCLUDES
Voltage, Power, Amps, Assist Level, Speed, Watt-hours, Amp-
hours, Controller Temperature and Trip Distance
TO TOGGLE BETWEEN THE MAIN SCREEN AND THE ADVANCED DISPLAY
SCREEN
Push the power button and the “assist up” button at the
same time for 1 second. The display screen will change to the
advanced mode.
NOTE:
The default display is the standard screen. This is the first
display that will appear when you turn on the e-bike.
UNDERSTANDING THE ADVANCED DISPLAY
MODE
VOLTAGE
The voltage displayed is the voltage of the pack. When the
battery is charged, the voltage will be higher (around 54V).
When the battery pack is depleted, the voltage will be lower
(around 43V). Voltage fluctuates when the battery is under load.
NOTE:
The voltage display is only accurate to about +/- 0.3 Volts
and should not be used for any scientific measurements.
AMPS
The amperage is the current flow through the wires. In this
case we measure the current flow through the controller. The
average will not be non-zero, as the system needs some small
amount of current to operate. When the motor is under load,
the Amp value will increase. The maximum value should be 20-
22A on the nine-transistor controller.
OPERATION
NOTE:
The Amperage display is only accurate to about +/- 1 A and
should not be used for any scientific measurements.
POWER
Power is the Voltage x Amperage and appears in Watts. This
is the power output at any moment of your e-bike. The more
power used to propel the e-bike, the higher this value will be.
NOTE:
Do not use the power display for any scientific
measurements.
AMP-HOURS
The amp-hour figure measures the amount of current flowing
out of the battery for a given hour. Reset the amp-hour and
watt-hour value by resetting the trip counter.
WATT-HOURS
The watt-hour is the measurement of how many watts are
sustained for a given hour. The watt-hour is the energy
consumed by the system. You can get a good indication of how
much energy remains inside the battery by subtracting the total
watt-hours consumed by the total “Wh” available in the battery.
NOTE:
Because there is a small error rate in the Amp and Voltage
measurements, the Watt-hour value will also have some degree of
error. Use the measurement for informational purposes and not for
scientific measurements.
ASSIST LEVEL
The assist level indicator shows the assist level you are in at
any given moment. It appears in both the advanced and the
standard display modes.
SPEED
The speed indicator measures the speed of the bike. This value
is measured from the motor’s internal speed sensor. If you have
changed to a new tire with a larger or smaller diameter than the
included tire, you may need to manually adjust the wheel
speed setting.
CONTROLLER TEMPERATURE
The controller temperature is measured by a temperature
sensor mounted inside of the controller near the transistors.
The temperature displays on the screen in Celsius. When the
e-bike is under load, the controller’s temperature will increase.
The bike’s performance will begin to decrease when the
temperature exceeds 80 degrees Celsius.
TRIP DISTANCE
The trip distance counts up from zero. The distance is calculated
by each rotation of the rear wheel. To reset the trip distance,
refer to
“Resetting the Trip Counter” on page 26
.
ADJUSTING PARAMETERS IN THE SETUP MENU
Adjust some of the parameters to control the behavior of your
e-bike.
TO ENTER THE SETTINGS MENU
Hold the “assist up” and “assist down” buttons for about 3
seconds, then release. You will now enter the setup menu. Here
you can adjust a few settings to control the behavior of the
e-bike.
