Welcome word
Congratulations on buying a power
assisted bicycle! Whether it is to make
your daily commute to work easier,
extend your riding time, help you keep up
with your friends or family or simply to
enjoy all the comfort, efficiency and fun
that this type of bicycle allows, we are
confident that you will appreciate all the
features and benefits your new bicycle
has to offer.
Safety Information
Although modern power assisted bicycles
look a lot like their regular counterparts,
there is quite a lot of technology behind it
and some notable differences in their
riding behavior, handling, and
maintenance requirements.
This manual has been created to provide
you with the instructions needed to safely
handle and operate your power assisted
bicycle, understand its function,
maintenance, and adjust its parameters.
It is important that you carefully read and
understand this manual before you ride
your power assisted bicycle. It should also
be kept handy for future reference.
This document is not a complete service
manual. We recommend that you seek
advice from a qualified technician if
anything is unclear.
Note that some manufacturers may not
honour their warranty if the handling and
operation has not been done properly.
The following symbols will be used
throughout the manual. They represent
important Warnings and Cautions about
the proper handling and operation of your
power assisted bicycle. They should be
carefully observed because failure to do
so might result in serious injuries, damage
or loss of performance of the system.
For other information not related to the
power assist system but regarding your
bicycle such as part assembly,
adjustments, maintenance, or riding
basics, please refer to your Owner Manual
provided separately at the time of
purchase.
Indicates important
information or a caution
about the proper use of a
component of the system.
Indicates a warning about
important safety information.

Always use your power assisted
bicycle according to the local laws
and regulations.
Don’t attempt to alter or
disassemble any component of
the power assist system.
Maintenance should only be performed by a
qualified technician.
Only use the original equipment
provided to operate and charge
the system. For replacement
parts, contact the bicycle dealer where the
product was purchased.
A power assisted bicycle handles
differently than a regular, human
powered bicycle. The acceleration
can be surprisingly effective and you should
get familiar with its behavior progressively
before riding on public roads or crowded
bicycle-designated paths.
Power assisted bicycles are
heavier than most other bicycles.
Always keep in mind that the
required distance needed for braking may
be longer than what you are used to on a
regular bicycle. This also calls for more
attention to the maintenance of your brake
system and tires.
Always look far in front of you
while riding to make sure you
have sufficient time to react if any
situation occurs. Avoid looking at the LCD
controller unit for a long period. Instead,
learn how to operate it with only a quick
glance.
A power assisted bicycle is not
suited for use by children or
certain persons with reduced
physical or mental capabilities. Make sure
you know and understand local laws and
regulations regarding this type of vehicle.
Laws and regulations regarding
the limitations and use of a power
assisted bicycle varies among
countries and even sometimes among states
and provinces. Make sure you know and
understand local laws and regulations if you
plan to travel with your power assisted
bicycle.
Important information about battery storage
Do not store the battery in a cold
environment, even for a short
period. If you must leave or store
your power assisted bicycle outside or in a
place that is not heated, you should remove
the battery and store it inside, at room
temperature. Cold temperatures can
damage the battery.
Store the battery away from high
heat sources such as direct
sunlight or inside a vehicle during
summer.
Make sure to follow all the
instructions described in section
Storing a power assisted bicycle
when storing the bicycle for a long period.

Quick Start Instructions
STEP 1: Charge the battery
1. Connect the AC power plug into the charger.
2. Plug the AC power plug into an electrical outlet. The LED
indicators on the charger will light up.
3. Connect the charging plug into the socket on the battery. The LED
indicators on the battery will blink, confirming that charging is
underway. Let the battery charge until it is fully charged.
4. The light on the charger will turn green when fully charged.
5. Pull the charging plug from the battery and replace the rubber
protector cap.
STEP 2: Turn the system on
1. Mount the bicycle and stand still over it or sit on the saddle with
a foot resting steady on the ground.
2. Press the power button on the battery. LED indicators will light
up and show battery charge level.
3. Press the power button on the controller for 2 seconds. LCD
Display will light up.
Do not turn the power assist system on before having mounted the
bicycle and being seated properly with at least one foot on the
ground. An unexpected ignition of the power assistance while
mounting the bicycle can result in serious injuries.

STEP 3: Select your assistance level
1. Press the button on the controller to switch to a higher power
assistance mode. LCD Display will show the mode you selected.
2. Press the button on the controller to switch to a lower power
assistance mode.
Note: Level 1 provides the least power assistance, while level 5 provides the
most.
Be careful if you decide to start off with a high power assistance mode
as the first pedal stroke may result in an unexpectedly quick
acceleration!
STEP 4: Start off
1. Make sure the path in front of you is clear.
2. Hold on to the handlebar with both hands and push on the pedals.
The power assist will kick in almost instantly.
Note: The power assist will only stay engaged when the rider is pedaling.
Ride safely!

Power assist mode description
How to shift through power assist modes
Switch through power assist modes using
the controller’s and buttons.
The LCD Display unit will show which
mode you’re in. Use a power assistance
level according to the current riding
conditions. Use a high assistance level
when going uphill or against a head wind
and switch to a lower assistance level if
you are riding on a flat road or with a tail
wind.
The operating range (battery
autonomy) of your bicycle is greatly
influenced by the power assistance
level you chose and how you manage it during
your ride. For more details on how to optimize
your operating range, see the following section on
operating range.
Mode 1 –Minimum assistance
Compensates for the power assist
system’s own weight without reaching
high speed. Use on flat surface with low
wind resistance. Operating range is at its
highest.
Mode 2 –Low assistance
Helps to reach a steady, slightly higher
speed than normal. Use on flat surface
with low to medium wind resistance. High
operating range.
Mode 3 –Intermediate assistance
Maintains a steady speed on variable
incline surfaces with medium wind
resistance. Optimal balance between
power assistance and operating range.
Mode 4 –High assistance
Reach greater speeds. Use on long inclines
and against strong wind resistance. Expect
a reduced operating range if riding with
this assistance level for a long period.
Mode 5 –Maximum assistance
Reach the highest speeds or get maximum
help to climb steeper inclines. Keep a
close watch at your battery capacity if
using this mode for a long trip.
