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 light represents about 20% capacity:
LIGHTS 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 in this section.
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 Zuma’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: Twist-And-Go (TAG) 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 1–3 are increasing levels of automatic motor assist.
Level 1 gives the least assistance; level 3 gives the most. Overall range decreases as assist increases.
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.
TAG (Twist And Go) mode
In TAG 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. You can still adjust the assist level, but it will only affect the
bike when you are in PAS mode.
Using the display
Press ‘ON/OFF’ to turn on the bicycle
After pressing ‘ON/OFF’, all ten meter lights will ash in
sequence, indicating that the bike is ready to ride.
The ‘Battery’ lights indicate remaining charge
The battery gauge provides ve indications of battery level.
The battery pack reports state-of-charge (SoC) information to
the controller and the meter box uses this information to display
very accurate battery charge information.
When the battery is depleted to the point of automatic shutoff,
the lowest gauge light will blink indicating the need to recharge
immediately. Of course, the bicycle can still be ridden with the
system turned off.
Press ‘TAG/PAS’ to change between PAS and
TAG mode
You can change modes at any time.
In PAS mode, the + and – buttons controls motor
assist power
These assist levels do not affect the throttle.
