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 rst
time, following the instructions below. Be sure to check Appendix
D in your owner’s manual, as well as the section 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 Appendix D in your
owner’s manual for more information.
The battery can either be charged on the bicycle using the
charging port on the seat tube, or off the bicycle using the
offboard charging adapter included with the charger.
If the battery is attached to the bicycle, and the bicycle is
turned on, the battery level indicator on the bike’s display will
show the current charge level.
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, you should 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 install the battery in
the bike, then turn the bike on. The battery level indicator on
the display will show the battery’s charge level.
Each bar represents about 20% capacity:
BARS BATTERY CHARGE
(1 ashing) <5%
1≤20%
2 ~20– 40%
3 ~40 – 60%
4 ~60 – 80%
5 ~80 – 100%
Using the battery
Installing the battery
First, open the battery collar quick release. Orient the battery
so the seat post is towards the front of the bike, then push the
battery into the bike’s seat tube until it bottoms out. Close the
quick release securely to lock the battery in place.
To adjust saddle height, use the seatpost quick release.
Don’t raise the battery to change saddle height; the battery
needs to be bottomed out in the frame at all times to maintain
electrical contact.
Removing the battery
To remove the battery, rst open the battery collar quick
release lever, then pull the battery straight up and out of the bike.

Riding and use
Be sure to read the “Electric Bikes” section of your IZIP owner’s manual, and specically pay attention to the section on
“Riding an electric bike”, before you ride for the rst time.
Getting ready to ride
First turn the bike on, following the instructions on the following page.
Mount the bicycle. Be sure you don’t accidentally twist the throttle, or turn the pedals; this could cause the bike to accelerate
unexpectedly.
Riding the bike
Using the motor
The purpose of the E3 Metro’s motor is to gently augment the effort you put into riding.
There are two assist modes, which offer different ways to control the motor: Power-On-Demand (POD) and Pedal Assist
(PAS). See the following page for more information on changing between modes.
PAS (Pedal Assist) mode
In PAS mode, the motor will assist you as soon as you begin pedaling the bike. You can choose how much assist the motor
gives by setting the assist level. If you do not pedal, no power is sent to the motor. Ceasing pedaling during the ride will cause
the motor to turn off. Motor power will be restarted when the rider begins pedaling again.
Assist levels control how much power the motor will add to your pedaling. In PAS mode, the assist level is shown on the
display, and can be changed at any time using the + or – buttons. Levels 1–4 are increasing levels of automatic motor assist.
Level 1 gives the least assistance; level 4 gives the most.
The throttle can be used to override the automatic assist, as long as the rider is pedaling. The throttle is never affected by
assist level; using the throttle, you always have control of up to 100% of the motor’s power.
POD (Power On Demand) mode
In POD mode, automatic motor assist is disabled, and the throttle alone is used to control the level of assistance; power is
available whether you pedal or not, and there are no assist levels.

Your IZIP E3Metro electric bicycle is equipped with a multi-function display. The display is your user interface to the bike.
Using the display, you can program the riding characteristics of the bike, monitor the system self-tests as they occur,
and note any system errors. The display also serves as a cycle computer, giving information regarding time, speed and
distance.

Turning on the headlight
and LCD backlight
Hold “–” for 3 seconds to turn on
the LCD backlight and the bicycle
headlight/taillight (if present).
The backlight will not function
unless the display is mounted on
the bike (with a battery installed).
Hold “+” for 3
seconds to change
from PAS to POD.
In PAS mode, the
motor will activate when
the system senses the
rider pedaling.
Use the “PWR LVL”
display function to
choose between light
assist, medium assist, and strong assist.
The throttle acts like a “boost”, allowing full control over 0-100% of motor
power at any time, regardless of power level.
In POD mode, only the throttle controls motor speed. There is no power
level setting in this mode, as the throttle can always apply 0-100% of motor
power. The pedal sensor is disabled, so there is no need to pedal.
Changing the assist mode
Tap SET to cycle
between functions.
In PAS mode, “+”
and “–” go directly
to the power level
screen.

Understanding the battery gauge
The gauge should show the battery level within a
few moments of turning on. Each “bar” represents
20% of the battery’s full charge.
If the gauge still shows completely empty after a
few seconds, check all connections to the control-
ler and display, and re-connect.
You may also need to begin riding the bike before
the battery “wakes up” fully and begins sending
the charge signal to the display.
Comm Error
Interpreting error messages
The IZIP display shows
coded error messages to
help diagnose problems
with the bike. These
messages appear
automatically if the system
senses an issue.
The most common error
message you may see
is Error 13: “Comm Error”. If this error comes up, it
means that the display is connected to the bike but
cannot communicate with the main controller (located
in the bike’s downtube).
Make sure the bike’s battery is installed and fully
charged. Check all connections between the display
and the controller, the battery and the controller, and
the display and its mounting bracket. Re-mount the
display, making sure it engages the mount fully.
If problems persist, or for information on other error
codes, please contact Currie Tech customer service.
Changing the display battery
The display can use power either from its
internal battery, or from the bike’s main
battery. The internal battery is used when the
display is disconnected from the bike, so you
can browse your ride data (like distance, time,
and average speed).
The display is powered by the bike’s battery
when connected to the bike. Even if the
internal battery in the display is dead or not
installed, the display will still operate using main battery power. However, if
you disconnect the display from the bike, it will immediately shut off.
The display uses one CR2032 3V watch battery. It should be available at
any store that sells electronics.
To replace, unscrew the display’s back cover using a coin. Remove the old
battery, then replace with a new one, oriented as shown (you should be
able to see the + symbol on the top of the cell). Replace the back cover,
tightening about 3/4 turn until snug.
After replacing the battery, you will need to re-set the clock. Trip time, trip
distance, average speed, and max speed will also be reset. The odometer
and total time values are stored in memory and will not be reset.
