Basics
IMPORTANT: The owner’s manual included with your bike contains most of the important
safety and usage information about this bike, which is not included in this system operation
manual. Be sure to read the owner’s manual before you begin riding or working on your bike.
Battery charging
You should charge the battery fully before
riding for the rst time, following the instructions
below. Be sure to check the section of your
owner’s manual discussing “Battery care &
safety” for additional information.
Charging procedure
Connect the power cord to the battery
charger. Plug the charging plug into the
battery’s charging port, then plug the wall
plug into a wall outlet.
The charger should always be plugged
rst into the battery, then into the wall
outlet.
Charging will begin immediately. The
charger’s LED indicator will light up to show
its status.

Charging error; see
“Charging issues” below
If the battery is turned on, the battery
level indicator on the battery will display the
battery’s charge level. See “Checking the
battery’s charge level” on page 10.
If the battery is attached to the bicycle,
and the bicycle is turned on, the battery level
indicator on the bike’s display will also show
the current charge level. See “Turning the
bike on and off” on page 11.
The battery does not have a “memory”. This
means that it can be charged at any time, or
partially charged, without causing damage
or decreasing performance.
Charge time
The amount of time needed to charge the
battery varies based on the battery’s charge
level. A completely empty battery will take
between 4 and 6 hours to charge. A battery
at 50% may only need 2-3 hours to come
to a full charge.
Checking the battery’s charge
level
Before riding, check the battery’s charge
level. If the battery is not fully charged, riding
range will be reduced.
To check the battery’s charge level, rst
press the battery power button to turn the
battery on. The battery level indicator will
display the battery’s charge level.
Each light represents about 20% capacity:
LIGHTS BATTERY CHARGE
1 ≤20%
2 ~20– 40%
3 ~40 – 60%
4 ~60 – 80%
5 ~80 – 100%
Using the battery
Installing the battery
To install the battery, place the battery’s
base onto the lower battery holder, then slot
the battery into the upper battery holder so
11/16
System Operation Manual - E3 Dash
10/29/14
that it engages the holder and locks into place.
The key does not need to be used when installing the battery.
Removing the battery
To remove the battery, unlock the battery lock with the key, pull the battery out of the
upper battery holder, then lift it out of the lower battery holder.
Turning on the power
1. Press the power button on the battery rst (see page 4). The battery level indicator
will light up.
2. Next push the power button ( ) on the control pad. The display will initialize, displaying
a countdown on its screen. During this countdown, the software is self-testing and calibrating
the bike’s sensors. While this countdown is shown, do not step on the pedals. The calibration
includes setting a zero-point for the pedal sensors, and any weight on the pedals will disrupt
this process. After the countdown completes, the bike is ready to ride.
To turn off the power
Typical way, using the handlebar controls: Press the control pad power button ( ) two
times, for 2 seconds each time. After the rst press, the bike will enter assistance level 0,
showing ‘0’ on the display’s assist level indicator (see “Assist levels” on page 12). After the
second press, the bike will turn off and the display screen will go blank, as will the battery
power indicator.
Alternative way, directly from the battery: Hold the battery power button for 2 seconds
and conrm the LEDs are off.

Riding and use
Be sure to read the “Electric Bikes” section of your owner’s manual, and specically
pay attention to the sections on “Riding an electric bike” and “Riding a high-speed electric
bicycle” before you ride for the rst time.
Getting ready to ride
First turn the bike on, following the
instructions in “Turning the bike on and off”
on page 11 of this manual.
Mount the bicycle. Be sure you don’t
accidentally twist the throttle, or put forward
pressure on the pedals; this could cause the
bike to accelerate unexpectedly.
Riding the bike
Using the motor
The purpose of the motor is to gently
augment the effort you put into riding the
bike. When you pedal hard, the motor assists
you more; when you pedal lightly, the motor
assists you less.
So, to ride the bike, all you really need
to do is pedal. The majority of the work of
controlling the motor is done automatically.
There are, however, three other controls
that affect how the motor runs: assist levels,
the throttle, and cruise control.
Assist levels
Assist levels control how much power tthe
motor will add to your pedaling. The assist
level is shown on the display, and can be
changed at any time using the and
buttons on the control pad (see “Control pad
functions” on page 14).
Levels 1–4 are increasing levels of
automatic motor assist. Level 1 gives the
least assistance; level 4 gives the most.
“T”, or “throttle-only” mode disables the
automatic motor assist, but leaves the throttle
active. Simply twist the throttle to control the
motor. In this mode, assisted top speed is
limited to 32 km/h (20 mph).
Level 0 disables motor assist completely.
Other functions such as the cyclecomputer
can still be used.
Throttle
The throttle can be used under certain
conditions to override the automatic assist:
In “T”/throttle-only mode, automatic motor
assist is disabled, and the throttle is always
active. In this mode, assisted top speed is
limited to 32 km/h (20 mph).
In assist level 1–4, when moving under
10 km/h (6 mph), the throttle is always
active, even without pedaling. This helps
you get moving from a stop, and helps when
navigating difcult terrain at low speed.
In assist level 1–4, when moving over 10
km/h (6 mph), the throttle is active as long
as you are pedaling. Here, using the throttle
has the same effect on the motor as hard
pedaling would.
The throttle is never affected by assist level.
Using the throttle, you always have control
of up to 100% of the motor’s power.
Cruise control
While in “T”/throttle-only mode, cruise
control can be turned on with the button:
First, pedal or use the throttle to reach
your desired cruising speed. Hold the throttle
13/16
System Operation Manual - E3 Dash
10/29/14
in a position that maintains this speed, and
press the button. You can then release
the throttle, and the bike will hold its current
speed, plus or minus about 3 km/h (2 mph).
Cruise control can be disabled at any time
by pulling either brake lever, twisting the
throttle, or by pressing the button again.
Cruise control will not function over 32 km/h
(20 mph). If you turn on cruise control while
traveling faster than 32 km/h, the bike will
decelerate to 32 km/h and hold that speed.
Using the brakes
The brakes are integrated with the electrical
system. When you pull the brakes, they not
only slow the wheel like a normal bicycle
brake, they also cut power from the motor.
See the “Brakes” section of your owner’s
manual for more information.
The display and control
pad
The display serves both as a cyclecomputer,
displaying speed and distance information,
and as an interface to the bike’s electrical
system. The functions of the display are
controlled by the control pad.
The display’s cyclecomputer
functions
The display has four cyclecomputer
functions. Switch between these functions
using the button. The function’s information
is displayed in the main display area.

The display’s electrical system functions
The display shows information about the bike’s electric assist, and gives the rider access
to several important functions:
Assist level
The current assist level is shown on the display (assist level indicator).
Battery level
The battery level indicator shows the current charge level of the battery. Each bar
represents about 20% capacity.
The low battery warning indicator lights up when the battery has less than 5% remaining
charge.
Maintenance information
The maintenance indicator lights up when there is a system error. An error code shown
on the display helps to diagnose the problem. See “Error codes” below.
Control pad functions
The control pad is used to control the various functions of the bike and display.
The control pad’s four buttons perform the following functions:
CONTROL PAD FUNCTIONS
Increase assist level (1–4), or to switch to throttle pure mode “T”.
Hold 2 seconds for backlight (and light set if installed).
Decrease assist level (4-1).
Turn bike on, one quick press
(turn on battery rst, p.4)
Change cyclecomputer display, quick presses to cycle through the options
(after bike is on)
Set power assist to 0, one 2 second press
(no pedal or throttle assistance, just power for the display)
Turn power off, one 2 second press
(must be in assist level 0 rst)
Activate cruise control.
The display backlight and any attached headlight/taillight is also controlled by the ambient
light sensor; they will automatically turn on in low light.
