Introduction
We wish to say hello and thank you for choosing our brand Littium by Kaos.
We hope that your new Berlin will give you great satisfaction.
This "User's Manual" contains important and necessary information for the use and
maintenance. It has been made so that you can use this electric vehicle with safety
and reliability obtaining a maximum performance of your time.
It is very important to read the manual in its entirety, paying special attention to
safety warnings. In addition, we recommend you observe the traffic regulations and
use the helmet.

Recomendations
Check the brakes before using the bike every time you use it and remember that it
will not stop equally in wet or icy conditions as you would on a dry road.
Check the tire pressure frequently. It must be 60 psi or 4.1 bar. Low tire pressures
can damage them. If you take the wheels with little pressure, it generates more
friction and reduces the performance of the bicycle.
Before using the bicycle for the first time, make sure it is properly assembled. In
particular, you must make sure that the pedals, saddle and handlebars have been
installed correctly.
When you have to replace the battery, deposit the old one in a recycling point, send
it back to us or to the seller.
The shipment of the bicycle is made through a reinforced box measuring 90x38x72
cms. Please save the box for the transfer in case of warranty.
Remember that this is an urban bicycle.

battery completes the charge, the LED turns green and can be unplugged. While the
charger is connected to the network without charging, the LED will be green in
standby mode.
Assembly
Assembling the bycicle for the first time
If you do not have minimal mechanical knowledge, it is advisable to go to
a specialized center.
1. Before starting, make sure the battery is off.
2. Hold the bicycle on its kickstand.
3. Mount the handlebar centered. Once centered, adjust it with the upper part
using two Allen screws. Use the tool that is included in the box.
4. The adjustment of the steering stem is made by placing the handlebars well
aligned with the steering. Then tighten the two side screws of the base of the
steering stem.

5. Adjust the desired height and firmly fix the side Allen nut.
6. Mounting the fender. Place the fender in its position and fix the top bracket
to the Allen screw. The support must be placed on the front of the fork.
7. You will see that there are two rods that connect with the supports that are
near the axis of the front wheel. Once you insert the front wheel, adjust these
rods so that the mudguard is approximately 1cm away. Carefully tighten the
small Allen screws that you will see on the plastic brackets.
TOP SUPPORT

8. Connect the two jacks of the front light. These cables have polarity, so if,
when the battery is connected, the light is not activated, it disconnects the
battery again and inverts the position of the cables.
9. Place the front wheel. Before tightening the manual closing of the axle,
lower the bicycle from the stand so that the wheel is firmly fixed in position
with the full weight of the bicycle.
10. Connect the front brake.
11. Check that all other nuts, bolts, and fasteners are tight.
12. Check the motor connection.
13. Check the brakes and brake levers work correctly.
14. Check the pressure of the wheels are 60 psi / 4.1bar.
15. Make sure the battery is fully charged. It is 50% factory charged, it is
important to make a first load of 4-5 hours before using the bicycle.

10
16. 2 security keys are delivered with the battery, they are unique so we
recommend saving one in a safe place or making a copy. Without the security
key, the battery can not be removed as it has an anti-theft system.
Use of the bycicle
•The battery of the rear grill has a switch on its left side. Pressing this switch
activates the bicycle and lights.
•The battery has a charge indicator on its upper face. Using the button with the
battery on, the status of the load can be checked.

contact your local distributor.
• Do not attempt to open or repair the charger.
• Avoid liquids and blows on the charger, you could cause damage.
• Do not place any object on top of the charger during charging. It must be well
ventilated to allow the generated heat to dissipate.
• During charging, if there is a peculiar odor or the temperature is too high,
please stop charging immediately.
•To avoid premature wear of the battery and loss of warranty, you must charge
and download it at least once a month.
• Do not use the battery in a very low state of charge.
• It is normal for the capacity to be reduced as a result of low temperatures.
• Do not leave the charger connected to the battery for more than 10 hours.
•The lack of use of the batteries causes a deterioration in the lithium. It is
recommended that during prolonged periods of non-use it is kept at 50% load.

DAO® system
Automatic wave distributor for electric bicycles. System developed and
registered by LITTIUM BY KAOS.
The objective is to avoid excess wiring, simplify the use and optimize the
performance of the Bicycle. This is the main reason to develop a new bicycle
concept.
The DAO® technology allows to have all the power of a good electric bicycle but
the interface between the bicycle and the user has disappeared. Thanks to this
technology, the behavior of the bicycle is semi-automatic. We do not have to be
aware of engine management. This adapts to our driving. And in this way we avoid
cable, buttons and complications.
However, you have an App for iOS and Android that you can download directly
from the respective official stores.
App operation.
Once downloaded and installed, click on the button with the littium logo to
