% !
%1. Use the brakes by squeezing the brake lever!
%2. Use the throttle !
%3. Push the Assist Up or Assist Down button!
Important notes about the Cruise Control Function
The cruise is considered a type of throttle and the maximum cruise controllable
speed is 20 mph in accordance with regulations.!
If the cruise control speed is set above 20 mph, the cruise control speed will default
to 20 mph. The speed will be allowed to decrease until 20 mph is reached. !
The pedal assist is still available when the cruise control is active. It may be possible
to pedal the e-bike faster than the pre-set cruise speed. However the cruise will
automatically resume if the speed is allowed to decrease to the pre-set cruise
controlled speed.!
If more power is needed to achieve a pre-set speed, for example when encountering
resistance such as a hill or headwind, more power will be automatically given the the
motor to attempt to maintain the preset speed. !
If the resistance is too much for the system to retain the pre-set speed, the resulting
speed will be limited by the capability of the motor. !

Note: The default display is the standard screen. This is the first display that will
appear when the e-bike is turned on. !
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 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 9 transistor
controller. !
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 displayed 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: The Power display should not be used for any scientific measurements.!
Amp-hours
The amp hour figure measures the amount of current flowing out of the battery for a
given hour. The amp-hour and watt-hour value can be reset 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.

Advanced Matrix Display (LCD Display) Instruction Manual
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. The measurement should be used
for informational purposes and not used for scientific measurements. !
Assist Level
The assist level indicator shows the assist level you are in at any given moment. It is
visible 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 Temp
The controller temperature is measured by a temperature sensor mounted inside of the
controller near the transistors. The temperature is displayed displayed on the screen in
Celsius. When the e-bike is under load, the controller’s temperature will increase. The
bike’s performance will began 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. The trip distance can be reset from the instructions provided above. !
Adjusting Parameters in the Setup Menu
There are a few parameters that you are allowed to adjust 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. !

Torque !
The Pedal Assist System is designed to provide you with motor assistance when you
pedal. The torque sensor setting allows you to choose if you want to use the torque
sensor measurement for the pedal assist. The torque sensor is on by default. In normal
operation, both the torque sensor and cadence sensor measurements will be used to
determine the pedal assist support level.!
On: The torque sensor will be activated and the pedal assist will factor in torque and
cadence measurements to determine the pedal assist support level.!
OFF: The torque sensor will be turned offand only the cadence sensor measurement
will be used to determine the pedal assist support level. !
Low Volts
The low voltage setting controls how deeply the battery is allowed to discharge. The
lower this setting, the lower the battery is allowed to discharge. !
Studies have shown that avoiding a deep discharge state can significantly increase
battery life. The low volts setting will set a limit to the lowest voltage that the System
will allow the pack to discharge. !
When the motor draws power from the battery pack, the voltage of the battery will
decrease. When the voltage further decreases and reaches the preset limits, the control
system will automatically limit power so the voltage never decreases below this pre-set
limit. !

Advanced Matrix Display (LCD Display) Instruction Manual
When the nominal voltage of the pack is nearing the low voltage limits which have been
set, very little power will be available to propel the e-bike. The battery needs to be
recharged to regain full power. !
Error Codes: !
The electronics system has some ability to self-diagnose and report a limited set of
faults. The faults will be reported as error codes displayed on the screen. Below is a
chart explaining the meaning of each error code. !
