ABOUT THIS MANUAL
WHY YOU SHOULD READ THIS MANUAL
This manual is written to help you to get the best performance, comfort,
enjoyment, and safety when riding your new E-Bike. The manual describes
specific care and maintenance procedures that help protect your warranty and
ensure years of trouble-free use. Please pay particular attention to the section on
battery charging and maintenance.
It is important for you to understand the features and operation of your new E-
Bike so that you can get maximum enjoyment with maximum safety. By reading
this manual before you go on your first ride, you’ll know how to get the most
from your new E-Bike.
It is also important that your first ride on a new E-Bike be taken under a
controlled environment, away from cars, obstacles, and other cyclists.
WARNING
Cycling can be a hazardous activity even under the best circumstances, Giving
Proper maintenance to your E-Bike is your responsibility as it helps to reduce the
risk of injury. This manual contains many “Warnings” and “Cautions” concerning
the consequences of failure to maintain or inspect your E-Bike. Many of the
Warnings and Cautions say, “you may lose control and fall” Because any fall can
result in serious injury or even death, we do not repeat the warning of possible
injury or death whenever the risk of falling is mentioned. Please note that those
risks are present.
Your E-Bike can provide many years of service, fun and fitness-if you take good
care of it.
Understand the features of your E-Bike and become aware of the challenges that
you will meet on the road. There are many things you can do to protect yourself
while riding. We will offer many recommendations and safety tips throughout this
manual. The following are those that we believe are the most important.

Always Wear a Helmet!
Helmets significantly reduce the possibility and severity of head injuries. Always
wear a helmet that complies with your state laws when riding the E-Bike. Check
with your local police department for requirements in your community.
Do not wear loose clothing that can become tangled in the moving parts of the E-
Bike. Wear sturdy shoes and eye protection. Also check your state laws
concerning other protective wear that may be required when riding the E-Bike.
Know Your E-Bike!
Your new E-Bike incorporates many features and functions that have never been
built into a bicycle before. Read this manual thoroughly to understand how those
features enhance your riding pleasure and safety.
Ride Defensively!
One of the most common cycling accidents is that when the driver of a parked car
opens his door into a rider’s path.
Another common occurrence is when a car or another cyclist moves suddenly into
your path. Always be aware of other vehicles around you. Do not assume that
drivers or other cyclists see you. Get prepared to take evasive action or stop
suddenly.
Make Yourself Easy to See!
Make yourself more visible by wearing bright reflective clothing. Keep your
reflectors clean and properly aligned. Signal your intentions so other drivers and
other cyclists can notice your actions.
Ride within Your Limits!
Take it slow until you are familiar with conditions that you encounter. Be
especially careful in wet conditions as traction can be greatly reduced and brakes
less effective. Never ride faster than conditions warrant or beyond your riding
abilities. Remember that alcohol, drugs, fatigue, and inattention can significantly
reduce your ability to make good judgments and ride safely.

Keep Your E-Bikes in Safe Condition
Check critical safety equipment before each and every ride
Know the Law
Cyclists are required to follow traffic rules. Additionally, some communities
regulate the use of motorized bicycles regarding minimum age requirements and
necessary equipment. Check with your local police department for specific details.
Correct Frame Size
When selecting a new E-BIKE, the proper frame size is a very important safety
consideration. Most full-sized bicycles come in a range of frame sizes. These sizes
usually refer to the distance between the center of the bottom bracket and the
top of the frame seat tube.
For safe and comfortable riding there should be a clearance of no less than 1-2
inches between the groin area of the intended rider and the top tube of the
bicycle frame, while the rider straddles the bicycle with both feet flat on the
ground.
The ideal clearance will vary between types of bicycles and rider preference. This
makes straddling the frame when off the seat easier and safer in situations such
as sudden traffic stops. Women can use a men’s style bicycle to determine the
correct size.

The Purpose and Benefit of this Booklet
This booklet describes assembly and safe operation of your electric bicycle.

Operation of Your Electric Bike
Your e-bike is driven by a motor embedded in the hub of the rear wheel and
cannot be driven directly by throttle. The motor is powered by a battery. The
amount of power delivered to the motor, and hence the accelerating force on the
e-bike, is controlled by you in a way according to the power-assisted mode you
choose.
Electric Assisted:
You must turn on the battery to use the e-bike in Electric-Assisted mode. In the
Electric-Assisted model, power assist is triggered when you pedal forward, and
power assist stop when you stop pedaling. In other words, power assist happens
as long as you pedal. You don't need to pedal hard. All you need is to apply a light
force to the pedals continuously to maintain the current flow. When you apply
one of the brakes, power-assist will automatically stop. Allowing the e-bike to
slow down and stop. Power assist will turn itself off when the e-bike has reached
the maximum speed of 25km/h.
Attach the Pedals
 Pedals are marked „L‟ and „R‟ on axle end, Screw the
pedal marked „L‟ into the left side of crank and
R‟ to
right.
 The right pedal attaches to the chain side crank
arm
with (clockwise) thread
 The left pedal attaches to the other arm and has
a left-
hand (counterclockwise) thread.
 Check your pedals before each ride to ensure that
they are tight. If you ride your bike with loose pedals,
you may strip the threads that hold the pedal to the
crank.

You should use the SHIMANO gear shifter at the handlebar to set the gears
appropriately according to road conditions and pedal as usual, you will find that
you need to exert a lot less effort and the e-bike travels faster and at a steadier
speed.
Note that the Battery level indicators on the handlebar will show the correct level
only when power is not being drawn from the battery.
Charging Your Battery
 Fully charge your battery before your first ride and then after any
operation, especially after long distance riding
 Your charger plugs directly to your battery pack with either a round (RCA or
XLR) connector or the same 3-prong plug as your bikes power cord.
 You must plug your charger to the bike first and then to the wall outlet.
NEVER PLUG A POWER CORD FROM A WALL OUTLET DIRECTLY INTO THE
BATTERY! YOU MUST USE YOUR CHARGER!
The light on the charger will be red while charging and turn green when finished.
When the charger's light turns green, please keep on charging the battery for 1-2
hours to ensure that the battery has a longer usage life. Then unplug your charger
from the battery and the wall.

 Always charge your battery before it gets too low. If you let your pack run
completely dead, it may not re-charge. It is a good idea to turn the key to
the position OFF and remove your key after any ride so that it will not be
left on accidentally.
 Your lithium battery pack switch has three positions. All the way to the left
is "off". Turn the key to the right to turn the bike on.
 To unlock the pack, push the key in slightly and turn to the left. It can then
be removed. Push-in and turn right to lock it on.
 The red button on top of the pack shows the power level when pushed. The
first light only comes on when the battery is too low to run the bike. The
next lights indicate low, medium, and full. The lights on the handlebar also
show the level.
 Remember: the sooner you charge after riding the longer your pack will
last.
 The Lithium battery is built with circuitry that prohibits over-charging and
excessive discharging.
 The battery charger is designed specifically for the bike; connecting the
battery to any other charger will void the warranty
Operation of Your Display
There are 3 power-aid levels, which are “LOW” “MED” and “HIGH” The bike
travels around 18km/h at level “LOW”,22km/h at level ”MED”, and 25km/h at
level “HIGH”.
Press the “ON/OFF” and “MODE” button to switch between different assist levels.
To the right of the “ON/OFF “button is the battery monitor, all of the 4 LEDs are
active, which indicates that the battery is full. Please recharge the battery
whenever the number of active led is less than 2.

Derailleur
The gears or derailleur should only be shifted as you pedal to keep the derailleur
in adjustment. The derailleur / shifting and pedaling are completely independent
of the motor.

Adjustments and Maintenance
 Your e-bike is designed for regular road for a single person. Using
 your e-bike for extreme maneuvers, such as extreme off-road use, jumping,
or carrying excessive load will damage the e-bike and could cause serious
injury.
 Do not use high pressure water streams to clean your e-bike, as water
might seep inside the motor or the wiring compartment and cause rusting
of electric parts or short circuits. Please use damp cloth with neutral
detergent to clean the bike body. Do not use alkali-based or caid based
detergent such as rust cleaners as it may result in damage and/or failure of
the bike body.
 Avoid parking your e-bike outside when there is rain or snow. At the end of
a trip where there was rain or snow, bring the e-bike inside and use a clean,
dry towel to eliminate any wetness.
 During daily use, please keep the controller clean and dry. Keep it away
from water, vibration, and contamination, otherwise the controller may be
damaged.
Warning!
Don’t over lubricate. If oil gets on the wheel rims or the brake shoes, it will reduce
brake performance and a long distance to stop the bicycle will be necessary.
Injury to the rider or to others can occur.
 The chain can throw excess oil onto the wheel rim. Wipe excess oil off the
chain. Keep all oil off the surfaces of the pedals where your feet rest.
 Using soap and hot water, wash all oil off the wheel rims, the brake shoes,
the pedals, and the tires. Rinse with clean water and dry completely before
you ride the bicycle.
 Using a light machine oil (20W) and the following guidelines, lubricate the
bicycle:

Some instructions on battery maintenance and charging
 Please charge the battery for 6-10 hours after its energy is consumed for
50%-70% of its total energy, in this way, the battery life will be longer. If
you leave the battery pack in your stock in less energy condition, it will
sleep to die easy. So please charge the battery pack full after each long-
distance ride.
 Do not charge the battery for a long time (that is “exceeds 10 hours”) in
summer; in case that the battery will be calefacient and broken.
 Recharging battery once a month during the period of storage
 Charging temperature:0℃～45℃
 Battery pack might not be fully charged when temperature is over
low or
over high. When the battery is charged the temperature
become a little
higher, it is normal under the temperature of 50℃.
 Do not make the charger jolty in the rear box if there is one box attached;
and the charger should be far away from water. The impact and shake
should be at the lowest degree when the battery is moved. Each special
designed charger is provided for each battery pack. Do not use other type
of charger for fear of burning out battery and causing danger.
