01
Thank you for sharing the space of your beautiful life with our electric bike. Owning,
riding and sharing this bike is a pleasurable experience.
This E-bike is equipped with an electric pedal speed sensing system to enhance your
cycling experience when you pedal. It means, while you are pedaling, you will find the
movement effortless as the motors will rotate as per your pedaling speed. A more
comfortable way of riding this bike would be by using the throttle. This means complete
electric transmission and you can enjoy the ride as effortless as it can be and also enjoy
the nature you pass by. You can ride to work, shop or just participate in leisure activities,
go to a picnic or carry this behind your vehicle to trail the ranges of the peak next door.
Perhaps you might not be very familiar with an E-bike, let's get to know it in a better
fashion.
Safety is our prime concern so the bike comes with auto braking power cutoff system
and is functional with key and a power button.
We wish you a pleasant ride and most importantly, do not forget to have fun!

Samsung INR18650 Type A 10S4P Arrangement wth under current and over voltage
protecton board.
Attenton!
Be careful to the electrical shock, do not disassemble the charger by yourself.
Contact your dealer in case of any emergency.
Battery precautons!
Batteres must not be burned but recycled.
Batteries should not be placed in environments with temperatures over 50
degrees Celsius.

10
Batteries and dry batteries should not be thrown in non-dedicated
garbage bins.
Batteries should not be exposed to water or placed in water.
Avoid battery complete discharging (excessive or deep discharge),
otherwise it will damage the battery life cycle (this is not within the
scope of quality assurance).
Charge after each use and if the e-bike is not in use, charge the
battery for at least four hours every month
Chargng of battery
The e-Bike is equipped with lithium battery to power the motor of 36v match. Compared
to other batteries, lithium battery has no "memory effect" and can be recharged even if
the charge is not completely exhausted.
After several times of charging and discharging, the battery can achieve the best
performance. It is better to charge fully for the first time. The charger will turn off
automatically when the light of charger turns red to green as an indication of full charge.
Instructions
• Firstly, connected the charger with the battery. The charging port of lithium
battery is located behind and below the battery cases' base, which is assembled
with IP 67 water-proof cover and dust proof sealant.
• Insert the charger pin into power socket.
• During charging, the charging indicator of the charger is red, indicating that
charging is in progress; when the charging indicator of the charger changes from
red to green, the battery is fully charged.
• After charging, please unplug the charger from power socket first and then unplug
the charger from the battery.
If the LED light does not turn on red, it is due to overheating of the
battery, and the
battery need to be cooled for a period of time before charging.

11
There is a state-of-charge indicator on the battery power display. Press the power
button to check the battery state, and the LED lamp displays the battery state:
3 LED = battery 100% charging.
2 LED = battery 40～70% charging.
1 LED =battery 0～40% charging.
Calculations: The conventional lithium battery chargers are
2A chargers. If the battery capacity is 10AH, it will take at least 5.5 hours to be fully
charged.
If the LED light is not on, it is indicated that battery should be charged
for without electricity
Battery nstructon
In order to avoid short circuit, do not let the positive and negative terminals of the
battery come in contact.
The battery is waterproof to prevent rain from penetrating. The water- proof
rating is IP64 (no harm caused by water splashing in any direction), so you can use
your bicycle on rainy days. Because the waterproof level of the battery case is
waterproof splashing, when the battery is exposed to water in rainy day, there is a
danger of disconnection. It is necessary to avoid rain in time and strengthen the
external water-tight measures of the battery case.
The battery causes no harm to environment since it use clean energy.
However, it should be recycled after the complete life span.
Under ideal conditions, the battery can be charged about 550 times. With
time and frequent usage, the current capacity of the battery will gradually decrease.
This is called depreciation of cells. Finally the entire battery needs to be replaced.
Do not place the battery in a high temperature environment (> 50 °C), such
as heating, direct sunlight and sources of ignition. Do not remove the battery. Please
consult your dealer if you have any questions. Please store the battery in a cool and
dry place in case you are not using it for a longer time and only use the charger
provided by the manufacturer to charge the battery.
0 0
All specifications noted are valid for 25 C – 35 C usage temperatures.
Note - Normally, the battery power supply capacity will be reduced by 1% for
every
1 C temperature reduction.

mantenance after 2 months of usage and once n 2 months followng. Regular
nspectons can avod unnecessary damage and repar costs afterwards. Keep your e-
bke n neat condton and avod settlng of dust, greasng the necessary parts are very
mportant and do make sure, you never mss a perodc mantenance wth your dealer.
Ths wll enhance the usablty. Here are a few tps for your reference.
•Check f the hanger fixng screws are loose or they fell off. Check f the fixng screws of
the battery cases’ base are loose.
•Check f the battery s charged accordng to the correct procedure n the manual and
stored n a place wthn the permssble temperature.
•Do not let the drt enter the gap between sensor and bottom bracket (Mddle of the Pedal
arms). Clean t regularly.
