FUNCTIONAL OVERVIEW
FUNCTIONAL OVERVIEW
• Use of a two-way serial communication
protocol, simple operation of the display via
the external 5-key keypad.
• Speed display: displaying the real-time speed
as SPEED, the maximum speed as MAXS and
the average speed as AVG.
• Km or mile: The user can choose between
km and mile.
• Intelligent battery level indication: With an
optimization algorithm, a stable display of
the battery level is ensured, and the problem
of fluctuant battery level indication common
with other displays is avoided.
• Automatic light-sensitive lights: The head-
light, taillight and display backlight will be
automatically turned on/ off depending on
lighting conditions.
• 5 levels off display backlighting: Different
levels, leave 1 is most dark, level 5 is highest
light.
• 6-Level-Support: setting power Levels 0 to 5.
• Trip distance indication: The maximum
distance displayed is 99999. Single-trip
distances TRIP or the total distance TOTAL
can be displayed.
• Intelligent display: including motor output
power W for riding, Remaining miles TO GO,
consumption of energy (calories) C.
• Display of error messages
• Walk assistance
• Settings: Various parameters, e.g. mode,
wheel diameter, speed limit etc., can be set
on the computer via a communication cable.
See the setting.
• Maintenance warning (this function can be
deactivated): Maintenance warning information is- dis played based on battery charge
cycles and riding distance. The display automatically estimates the battery life and gives
warnings when the number of charge cycles
exceeds the set value. A warning will also be
displayed when the accumulated total riding
distance exceeds the set value.
• With Bluetooth module: Can connect to an
send message to phone, and phone can
display complete information of the entire
cycle.

• Headlight/ Display Backlight Switch
Press
for 2 seconds. The backlight of
the display as well as the headlight and taillight will be turned on. Press again for
2 seconds to power off the display backlight
/ headlight / taillight. There are 5 levels of
backlight brightness that can be selected by
the user. (If the display is turned on in a dark
environment, the display backlight / headlight / taillight will be turned on automatically. If the display backlight / headlight / taillight are turned off manually, they also need
to be turned on manually afterwards)
• Walk Assistance
Press
for 2 seconds. The e-bike enters
the walk assistance mode, and the symbol
WALK is displayed. Once the key is
released, the e-bike will exit the walk assistance mode.

speed (AVG) and single trip distance (TRIP)
can be cleared. Briefly press
(< 0.3 sec-
onds) to enter the km/mile setting interface.
If the user does not reset the data, the single
trip distance and the accumulated total riding time will be automatically cleared when
the accumulated total riding time exceeds
99 hours and 59 minutes.
* The data will not be cleared when the
display’s light-sensing function is set to 0 or
when it is switched off!
• Km/mile

necessity based on such information as the
accumulated riding distance and the battery
charge cycles.
2) When the accumulated total riding distance exceeds 5,000 km (can be customized
by the manufacturer), the display will show
the symbol
started up, the sign for accumulated riding
distance will flash for 4 seconds, indicating
that maintenance is necessary.
3) When the number of battery charge cycles exceeds 100 (can be customized by the
manufacturer), the display will the symbol
. When the display is started up,
the sign for battery will flash for 4 seconds,
indicating that maintenance is necessary.
4) The maintenance alert function can be
disabled: settings ->maintenance alert (MA)
