Attention

· Please carefully check whether all parts are in good condition before. If there is any problem, please contact the dealer in time.

· Abide by the city traffic laws and regulations when using.

· Slow down when encountering rain, snow and passing through slippery roads, increase braking distance when braking, and avoid traveling as much as possible to ensure safety.

· Do not disassemble parts without authorization. If you need to replace them, please purchase standard parts from distributors.

· Wading is prohibited during riding or when riding in rainy days. When accumulated water floods the lowest position of motor hub, it will cause line failure.

· Do not contact the metal point of the battery, otherwise it will produce a large short-circuit current and cause an accident and fire, please pay attention! · Wear a helmet when riding an electric bicycle, and carry articles according to the law.

· Do not park electric bicycles in the foyer, stairs, walkways and safety exits of buildings.

· Due to the continuous improvement of products in technology, there may be different things between the physical objects and the instructions. Please take the physical objects as the standard.

Special Tips:

Do not park electric bicycles in the foyer, stairs, walkways and safety exits of buildings. Electric bicycles should not be charged and parked in residential buildings. When charging, they should stay away from combustibles and flammable materials and avoid charging for a long time. Waste batteries cannot be disassembled without authorization.

 

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.

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

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.

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).
