Riding Precautions
· Accelerate slowly when starting, and help with pedals when climbing, which can prolong the service life of batteries and motors.
· The bicycle controller is equipped with overload protection function, which will automatically cut off the power supply when overload occurs, and when it returns to normal, the power supply of the electric bicycle will be automatically turned on.
· The maximum load capacity of this bicycle is 180kg (including the weight of riders). Do not overload driving. When driving on complex roads, try to ride and turn on the shock absorption function.

Parking Precautions
· When implementing, the power switch should be turned off to prevent accidents caused by sudden start of the bicycle due to unintentional rotation of the speed regulating handle. When parking, turn off the power supply, lock the battery and remove the key.
· For the sake of your driving safety and keeping your bike in the best condition, please maintain it regularly.

Battery Storage
· Please store the battery at the ambient temperature of 20 ~ 25℃, and do not store the battery in an environment higher than 50℃, otherwise it will lead to irreversible capacity attenuation of the battery.
· If the bicycle is not used for a long time (such as winter, summer or other special
circumstances), the battery must be taken out and stored separately, maintained and charged regularly, otherwise the battery may run out and cause irreversible damage.
· The most suitable storage capacity of the battery is 50%, and long-term storage of less than 10% or more than 90% will lead to irreversible capacity attenuation of the battery.

Instrument Description

Power on/off

Long press  to power on/off the display. When the display is off, it will not use the battery power and the leakage current is less than 1uA.

NOTICE:The display will automatically shut off if it is not used for more than 10 minutes.

Display interface switching

When the display is powered on, it will show the Current Speed (km/h) and Trip Odometer (km) by default. Short press  to switch between Trip Odometer(km), Odometer (km), Maximum Speed (km/h), and Average Speed (km/h)

Walk boost mode

Long Press and hold , the electric bicycle enters the walk boost mode. The electric bicycle will walk at a fixed speed of 6 km per hour and the display shows . Release  to stop the power output immediately and restore to the state
before walk boost.

NOTICE:The walk boost mode can only be used when pushing
the electric bicycle, please do not use it while riding.

PAS level selection

Press /  to switch PAS level of electric bicycle, thus changing the motor
output power

Correct Use Of Charger

· Electric bicycles are equipped with special batteries, which must be charged by the special charger provided by our company. Before charging, the electric bicycle must turn off the power supply. When charging, the output end of the charger is linked to the electric bicycle, and then the other end of the charger is linked to the power supply for charging. The red ndicator of the charger lights up, indicating that charging is underway.

Battery Disassembly And Assembly

Battery disassembly and assembly: The electric bicycle has built-in hidden battery and hidden lock. When taking out the battery, fold the electric bicycle and open the lock with the key to take it out.

1. Open the safety buckle first, and then open the folding buckle.

2. Insert the key and turn clockwise to lock the battery. Turn counterclockwise to remove the battery.

3. Take out the key and take out the battery.

Precautions For Battery Use

· It takes about 6 hours to charge the battery. When the indicator turns green, it indicates that it is fully charged. Turn off the power connected to the charger first, remove the charger, and try to avoid charging for a long time (avoid more than 12 hours)
· When charging, the charger and battery should not be covered with anything to avoid danger caused by overheating. It is recommended to start charging when the battery charge is less than 20%. When parking for a long time, it should be stored at 50% of the power, and must be charged once every other month.
· If you smell peculiar smell during charging, please stop charging immediately and send it to the maintenance office for maintenance.
· When charging, do not touch the battery or charger, and children are strictly forbidden to touch the charger.
· Keep the charger or battery away from flammable materials. Do not charge near babies and children. Do not charge in an unattended state for a long time. For the safety of you and your family, it is recommended not to charge in the early morning.
· Please do not use other brands of charger charging, charger is high-voltage circuit, do not disassemble without authorization.

Energy Consumption Description

* The battery should be fully charged before long-distance travel. Rugged road conditions and hilly terrain will consume more energy.
* Carrying more weight on an electric bicycle will consume more energy.
* When an electric bicycle runs at low temperature, its cruising range will be reduced.
* When the battery is turned off, your electric bike will be used as an ordinary bike.

Pattern Description

	The key is opened, the instrument is opened, and the switch is twisted. The electric bicycle is driven by electricity.
	The key is turned on, and the instrument is turned on. At this time, the electric auxiliary mode will be started, which is driven by manpower and electric power.
	Riding an electric bicycle, the electric bicycle is driven by manpower.

· In pedal assist mode, assist is triggered when the pedal is pressed forward, and is stopped when the pedal is stopped. When you brake, the power assist system will automatically stop, allowing the e-bike to slow down and stop. When the e-bike reaches the maximum speed of the gear you have selected, the power assist will turn itself off. The key is opened, the instrument is opened, and the switch is twisted. The electric bicycle is driven by electricity.

Motor Description

When the electric bicycle starts, the input current of the drive motor is large, and the motor will have a certain noise to overcome the resistance to reach the speed. It is the friction sound of the current torque and the magnetic force, which is a normal phenomenon. If the starting current of the electric bicycle is increased, all noises will be more obvious. This is a normal phenomenon and will not affect the use of the electric bicycle. (Note: When the electric bicycle starts, it can be accelerated slowly when accelerating. At this time, the starting current will not be too large, and the noise of the driving wheel will be relatively small. At the same time, it will be beneficial to the battery life).
