Basics
IMPORTANT: The IZIP 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 first
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 first into the
battery, then into the wall outlet.
Charging will begin immediately. The charger’s LED indicator
will light up to show its status.

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 that it engages the holder and locks into place.
The key does not need to be used when installing the battery.
Removing the battery
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 5.
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.
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 5.
Turning the bike on and off
The bike is turned on and off in two places: the battery and
the control pad.
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.
To turn the bike on...
First turn on the battery by pressing the battery power button.
The battery level indicator will light up.
Charge time
After the battery is turned on, you can turn on the display by
pressing the control pad power button ( ).
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.
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 the bike off...
Press the control pad power button ( ) two times. After the
first press, the bike will enter assistance level 0, showing ‘0’
on the display’s assist level indicator; see “Assist levels” on
page 6 below. After the second press, the bike will turn off.
Alternately, you can turn the bike off by holding the battery
power button for 2 seconds.

System Operation Manual - IZIP E3 Dash
Riding and use
Be sure to read the “Electric Bikes” section of your IZIP owner’s manual, and specifically pay attention to the sections on
“Riding an electric bike” and “Riding a high-speed electric bicycle” before you ride for the first time.
Getting ready to ride
First turn the bike on, following the instructions in “Turning
the bike on and off” on page 5 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 E3 Dash’s 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 the motor will add to
your pedaling. The assist level is shown on the display, and can
be changed at any time using the
button on the control
pad (see “Control pad functions” on page 7).
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 difficult
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 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 E3 Dash’s 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 IZIP 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.
