Transmission using
Transmission diagram
When using a gear system, try not to skip gears, which can easily damage the gear. It is not possible to change two gears at a time above, should be
a level of adjustment, can better protect the gear system.
Do not reverse the gear system when the bike stops running, or when it is going downhill. This will not only be bad for the gear system, but also
may cause accidents.
If it is their gear fault, or gear is not accurate situation, will affect the performance of the transmission, at this time should be timely to the
professional bike shop maintenance, in case of aggravation of the fault.
When using the transmission system, also pay attention to the following details

To speed up, start with a lower gear and shift to a higher gear as you speed up
When going uphill, the speed will decrease and the gear will be lowered to maintain a certain
pedal strength
Downwind will speed up, increase gear to maintain a certain degree of pedal strength
The above is riding advice, according to personal habits to reasonable use of gear

Before use, confirm that the battery model is the original battery of the whole bike, do not use any other brand of battery.
Check the appearance of lithium battery intact, no damage, leakage, heat and water, smoke and other obvious phenomena.
In order to ensure the safety of transportation, the battery's output power is about 30%. Due to the self-consumption during the transportation
and storage cycle, the battery is low or no electricity in the first use. This is a normal phenomenon.
About batteries
Note before use of lithium battery
The best operating environment is 10℃-45℃
At low temperature, available capacity of lithium battery will decrease to different degrees. The specific reference degree is as follows:
The available capacity is about 70% at -10℃, 85% at 0℃and 100% at 25℃.If the battery has odor, heat, deformation and other abnormal
conditions, please stop using immediately, away from the battery and contact the after-sales department.
The battery is not a part that can be repaired by the user. If there is any abnormal
phenomenon, please contact the after-sales department for maintenance.
Disassembling the battery without permission will not be covered by the three-pack
policy and may cause the battery to generate heat, smoke, fire or explosion.
Using the environment
Warning

Charger port of the battery
When the battery is placed on the bike, it will constantly consume the battery power. After the bike is placed for a period of time, the meter
shows that the decrease of the battery power is normal.
Please store the battery in the ambient temperature from 0℃to 25℃. Do not store the battery in an environment higher than 45℃,
or it will cause irreversible
capacity decay of the battery.If the bike is not in use for a long time (such as winter, summer or other special circumstances), the battery
must be taken out and stored separately and charged regularly. Otherwise, the battery may be completely exhausted and irreversible damage
may occur. For such problems, the battery fault will not be within the scope of three guarantee.
The best storage capacity for a battery is 50%. Long-term storage of less than 10% or more than 90% of the battery will lead to irreversible
capacity decay.
Avoid storing batteries in hazardous locations. Falling may cause uncontrolled damage to the battery interior and may cause battery leakage,
heat, smoke, fire, or explosion.
Storage environment
Use the original charger to charge the battery. Do not use other brand or model charger to charge the battery.
Please charge the battery at the ambient temperature of 10℃~ 40℃to ensure that there are no flammable substances around and
good ventilation.
Charging time indicates that if the charging time of the battery is less than 12 hours, overcharging will affect the battery life and there are
safety risks.
In the early stage of charging, the electric quantity rises quickly, while in the later stage, it is the procedure set for charging safety, which is the
normal situation.
When charging in winter, the outdoor temperature is relatively low. When the environment is below 0℃, the battery will stop charging.
This is a normal phenomenon.
Outdoor charging is strictly prohibited in bad weather.
During the charging process, the charger has a temperature rise effect, and the surface temperature is relatively high, which is a normal
phenomenon. Please feel free to use it, and pay attention to avoid children touching it.
