Safety & Warnings
Cycling can be a hazardous activity even under the best circumstances. Giving proper
maintenance to your electric 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 electric bike. Many of the warnings and cautions say, “You may lose
control and fall” and that can result in serious injury or even death.
The warning of possible injury or death will not be repeated whenever the risk of falling is
mentioned.
Important Safety Information
There are many things you can do to protect yourself while riding. Recommendations and
safety tips are offered throughout this manual including the following:
Always Wear A Helmet
Helmets can significantly reduce the possibility and severity of head injuries. Always wear a
helmet that complies with your state laws when riding the Electric 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 Electric Bike.
Wear sturdy shoes and eye protection. Check your state laws concerning other protective
wear that may be required when riding the Electric Bike.
Know Your Electric Bike
Your new Electric 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 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. Be prepared to take evasive action or stop suddenly.
Make Yourself Easy to See
Make yourself more visible by wearing bright reflective (high visibility) clothing. Keep your
reflectors (not included) clean and properly aligned. Signal prior to turning so that drivers and
other cyclists can anticipate your actions.
Ride Within Your Limits
Take it slow until you are familiar with conditions that you encounter. Be very careful in wet
conditions as traction can be greatly reduced and brakes become less effective.
Never ride faster 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 Electric Bike in a Safe Condition
Follow the inspection and maintenance guidelines beginning on page 12. Check critical safety
equipment before each ride.

Know the Law
Cyclists are required to follow the traffic rules. Additionally, some communities regulate the
use of motorised bicycles regarding minimum age requirements and necessary equipment.
Check with your local police department for specific details.
Correct Frame Size
When selecting a new bicycle, the 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 centre of the bottom bracket and the top of the frame seat tube.
For safe and comfortable riding, there should be clearance of not less than 3-5cm
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 depending on the type of bicycles and rider preference. This
makes straddling easier when off the seat and safer in situations such as sudden stops.
Checking the Battery Pack Before Using for the First Time
The battery pack is partially charged. To ensure full battery pack capacity, completely charge
the battery pack before using it for the first time.
Battery care:
•Even with proper care, rechargeable batteries do not last forever. Every time the
battery is discharged and subsequently recharged, its relative capacity decreases
by a small percentage. You can maximise the life of your battery by following the
instructions. Battery should be fully charged till recommended charge times
immediately when they are received.
Li-LON recommended charge time: 5-6 hours
•For a complete, 100% charge, leave the battery on the charger for one full hour
after the charger indicator light turns green.
•Never charge batteries for more than 18 hours straight.
•Li-ion batteries do not have a “memory”. Partial discharge/charge cycles will not
harm the batteries' capacity or performance.
•The rated output capacity of the battery is measured at 25°C. Any variation in this
temperature will alter the performance of the battery and shorten its expected life.
High temperatures especially reduce overall battery life and run time.
•Always be sure to turn the bike power switch to “OFF” after every use. If you leave
the power switch in the “ON” position or your product has not been charged for a
long period of time, then the battery may reach a stage at which they will no
longer hold power.
Many Electric Bike service and repair tasks require special knowledge and tools. Do not begin
to perform any adjustments/modifications or services on your Electric Bike if you are not
qualified or authorised to perform them. Improper adjustment or service may result in
damage to the Electric Bike or an accident which can cause serious injury or death.
Helmets
Always wear a helmet fitted properly, which covers the forehead when riding a bicycle.
Many states require specific safety devices. It's your responsibility to familiarise yourself with
the laws of the state where you ride and to comply with all applicable laws, including properly
equipping yourself and your bike as the law requires.

4
Bicycle safety helmet should always be worn while riding your bicycle.
The correct helmet should:
•Be comfortable
•Be lightweight
•Have good ventilation
•Fit correctly
•Cover your forehead

Front Wheel
1. Make sure that the brakes are loose enough to allow the wheel to pass through the
brake pads easily.
2. Place wheel into fork dropouts.
3. Install retaining washers with the raised lip pointed towards the fork and insert them
into the small hole of the fork blade.
4. Install the axle nut and tighten it. Make sure the wheel is centred between the fork
blades.
5. Spin the wheel to make sure that it is centred and clears the brake shoes.
6. Tighten the brakes if necessary.
Saddle Position
Correct saddle position is an important factor to get the best performance and comfort from
your Electric Bike.
If you find the saddle not positioned comfortably, then there are two adjustments to make it
right.
A: Up and Down Adjustment
Your leg length determines the correct saddle height.
The saddle position is said to be at correct height, if you can just reach a pedal in the lowest
position with one heel when you are seated and if the crank arms are parallel to the seat tube.
To check for correct saddle height, perform the following:
1. Sit on the saddle and place one heel on a pedal.
2. Rotate the crank until the pedal with your heel reaches the lowest position and the
crank arm should be parallel to the seat tube. Your leg should be straight and just

7
touching the centre of the pedal. If this is not the case, your saddle height needs to be
adjusted.
B: Saddle Tilt Adjustment
Most people prefer a horizontal saddle, but some riders prefer the saddle nose tilted slightly
up or down.
You can adjust the saddle by loosening the saddle quick release and then tilt the saddle to
the desired position and retighten the saddle quick release.
Tighten it enough so that you cannot move or jiggle the saddle. Very small changes in saddle
position can have a substantial effect on performance and comfort. Consequently, whenever
you make a change to your saddle position, make only one directional change at a time and
make the changes in small increments until you find the position you are most comfortable.
How to Fold the Bike
1. Turn the key switch to OFF.
2. Unlock the handlebar quick release lever (A, Picture 1) and push down the handlebar
to the lowest position, then lock the handlebar quick release lever.
3. Unlock the handlebar quick release lever (A, Picture 2) and rollover the handlebar.
4. Rotate the pedal upward so it is perpendicular to the ground. (A, Picture 3)
5. Release the lock lever from its clasp on the right side of the Electric Bike. (A, Picture
4)
6. Rotate the lock lever (A, Picture 4) clockwise until it points backward, pull the locknut
and rotate the lock nut (A, Picture 4) out from the Electric Bike until the nut clears the
lock plate (B, Picture 4).
7. Grasp the seat and the handlebar. Pivot the front half of the frame rearward around
the hinge until the front wheel is beside the rear wheel.

Operation
Please read and understand these instructions completely before operating your Electric Bike
to prevent serious injury to yourself and others and to prevent damage to the bike.
Important notices:
•Always recharge the battery immediately after each use. Failing to do, may
damage the battery.
•When stored over 1 month, the battery should be checked and fully recharged
before riding.
Riding Method
Be familiar with all the spare parts of the Electric Bike and test all the electric functions before
riding. Make sure all the spare parts for the bicycle are in good condition. Check the power of
battery and the pressure for tyres.
Starting Up
Insert the key into power switch at the right side of battery box, turn to “ON” status, the
power display will turn on, meaning the power supply is normal.
1. Start-up with Accelerator: Turn the accelerator from outside to inside (anticlockwise)
and the rotation angle should be from small to large for starting, then you can adjust
the speed by turning the accelerator slowly. The speed can increase to 25km/h;
however, actual speeds depend on the weight, the road, tire pressure and other
factors.
2. Start-up with Pedal Assist: After turning on power, you can also turn the pedals for
one and half cycles to start-up the Electric Bike, then you can control speed of the
bicycle by pedalling, if you pedal faster the speed of the bicycle increases, but do not
pedal too hard, it can cause damage to the components of Electric Bike.
Riding Safely
Riding on the road:
1. The speed should be increased slowly after start-up, to prevent wasting of energy and
damage to electrical components; it is much better to start-up using the pedal assist
method.
2. Ride using the pedals when climbing inclines, in order to extend the service life of
battery and the motor.
3. Try to reduce frequent braking and start-up while riding, in order to save energy.
4. To stop the Electric Bike, you can release the accelerator by turning it clockwise, the
speed will decrease and stop.
5. Do not accelerate and brake together while riding, you can release the accelerator first
and then brake. If the motor overloads by accelerating and braking at the same time, it
can damage the other components of the Electric Bike.

6. The load standard weight is 75kg (including the rider weight), please do not overload
with more wright.
7. A rear brake system has been installed to the Electric Bike, it will automatically cut off
power supply to the motor and slow down when you pull the brake and then the rear
brake in the back tyre stops the Electric Bike.
Parking:
1. Shut off the power switch after you get off, in order to prevent accidents by
accidentally turning the accelerator and starting up the bicycle abruptly.
2. Do not start bicycle frequently while resting, to ensure the service life for battery,
motor and electric switch.
3. Shut off the power after parking and remove the key.
Battery charging:
1. When the ride is over or the battery is running out, charge the battery immediately.
2. Charging can be performed in two ways:
a. Remove the battery from the bike and then charge it
b. Charge the battery while it is connected to the Electric Bike.
3. Attach the charger connector to the bike and the AC connector to a wall outlet.
4. There is an LED indicator on the battery charger unit. The LED glows red when the
power is connected and the battery is charging.
5. When the LED turns green, it means the battery is full.
•For Li-ion battery, the recommended charge time: 5-6 hours.
6. Do not charge continuously for more than 18 hours.
7. After charging, unplug the input socket first (from the outlet), then unplug the output
socket (from the bike).
8. The battery charger must provide constant voltage. Fluctuating voltage or fluctuating
power supply may damage the battery storage cells.
Inserting, Unlocking and Removing the Battery
•Insert the key into the keyhole.
•Turn the key switch to ON when using the Electric Bike. (C, picture 5)
•Turn the key switch to OFF after using the Electric Bike. (B, picture 5)
•Turn the key switch to unlock position (A, picture 5), then the battery unlocks and
becomes removable.

Power Indicator
When the throttle or sensor is engaged (Powering the motor) and the bicycle is in motion, the
LED on the battery gauge (on the throttle or separate unit) indicate instantaneous line
voltage as measured at the battery terminals and not the available energy in the battery pack.
The line voltage will wing out on a dead stop or going up a steep hill, the motor will be under
a high load and may show a reduced number of LED indications or show the “Yellow” or even
“RED” LED.
When the throttle is disengaged (i.e. no power to the motor as the bicycle is stationary or
coasting) the LED on the throttle will indicate the voltage of the battery pack. The voltage of
the battery pack will rise when no load is on the motor. The best way to know the remaining
battery life is to check the throttle LED after reaching cruising speed on a flat straight road,
as this will allow the battery voltage to stabilise and give a much more accurate reading.
