3.SAFE RIDING
It is very important to be relaxed and wear properly while riding, observe traffic regulations, do not rush,
always ride carefully and relaxed.
Usually, most people would ride their newly bought vehicle very carefully, but after they become familiar
with their vehicle, they tend to become reckless which may result in an accident.
To remind you：
Please wear a helmet, and properly tighten the helmet belt when riding.
Clothes with open or loose cuffs may be blown by wind and cause the cuffs caught on the steering
handlebar and thus affects riding safety. So put on clothes with tight sleeves.
Hold the steering handlebar by both hands when riding. Never ride with only one hand.
Observe the speed limit.
Wear suitable low-heel shoes.
Perform periodical maintenance and inspection in accordance with the schedule.
CAUTION：
Modified vehicle will affect its structure or performance, and cause poor engine operation or exhaust
noise, which will result in shorter vehicle service life.
Besides, modification is illegal and does not conform to the original design and specifications.
A modified vehicle will not be covered by warranty. Therefore, do not modify your vehicle at will.
Tire and rim modifications will make it unsafe to ride and may cause severe injury or death.

4
Keep your body such as shoulders, arms, palms, and waist relaxed and ride with the most comfortable
posture in order to react quickly when necessary.
Riding posture will greatly affect riding safety. Always keep your body’s gravity in the center of the
seat. If your body’s gravity is on the rear part of seat, the front wheel load will be reduced, and this
will cause the steering handlebar shaking. It is dangerous to ride a vehicle with an unstable
handlebar.
It will be much easier to make a turn when the rider inclines his body inward. On the contrary, the
rider will feel unstable if his body and the vehicle do not incline when making a turn.
The vehicle is hard to control on a bumpy, unleveled, unpaved road. Try to know the road conditions
in advance, slow down and use your shoulder’s force to control the handlebar.
Suggestion: Do not load unnecessary objects on the front floor panel; avoid affecting the riding
safety and the operation of steering handlebar.
CAUTION：
The rider’s feeling on the handlebar is slightly different with or without a load.
Overload may cause the handlebar to swing and affect the riding safety.
Therefore, do not overload your vehicle.
Overload will cause the vehicle become unstable and hard to control, it may cause serious damage to the
tires and rims; it may also change the center of gravity, which could result in an accident that could cause
injury or death. Do not exceed the maximum authorized load.
If equipped with USB charging function, do not use it in rainy days
4.USE GENUINE SPARE PARTS
To maintain the vehicle’s best performance, each part’s quality, material, and machined precision must
conform to the design requirements.
“SYM Genuine Spare Parts” are made from the same high quality materials used for the original vehicle.
No parts would be sold to the market until they could meet the designed specifications through
sophisticated engineering and stringent quality control.
Therefore, it is necessary to purchase “SYM Genuine Spare Parts” from “SYM Authorized Dealers or
Franchised Dealers” when replacing spare parts.
If you buy the cheap or fake substitute parts from the market, neither quality nor durability will be
guaranteed.
Also, it may result in unexpected troubles and reduce the vehicle’s performance.
Always use SYM Genuine Spare Parts to ensure its long service life.

BATTERY CHARGER USAGE METHOD
Charger Usage Instruction:
Connect charger output cable and battery first, then connect power cable and 100V-240V socket. Two green
lights are always on shows charging finished or standby state. One green light is on and one green light is
flashes shows the battery is being charged.
Please use SYM authorized charger.
CAUTION:
Please charge the battery indoors, avoid sun ray, moisture, and dust.
Prevent rain, liquid, foreign metal material from falling into the charger to avoid short circuit or burnout.
After charging, please remove the cables from the socket to avoid power consuming.
Do not charge battery of other form and brand with the charger to ensure the life span and safety of the
charger and battery.
Please be sure to use the attached lithium battery charger to charge the lithium battery. If you use other
unauthorized chargers or devices for charging, it may cause serious consequences such as smoke and
fire of the lithium battery.
CAUTION:
In normal temperature, the battery can be fully charged in 5-6 hours; however, if the ambient
temperature or battery temperature is too high (over 55℃) or too low (under 0℃), to prevent
deterioration, the charger will prolong the charging time to 5-7 hours.
When the temperature of the lithium battery is too high, the controller will intelligently reduce the
power to slow down the continuous high temperature of the lithium battery (to protect the lithium
battery). When the temperature is reduced, the controller will return to normal power output.
With the repeated charging and use of lithium battery, the battery capacity will gradually reduce.
(when the battery capacity is reduced, even if it is fully charged, the mileage of the vehicle will
gradually become shorter.).
When the vehicle is driving in a very hot or cold place, the endurance mileage of the lithium
battery will be reduced. If the power battery returns to the normal temperature of 25 ℃, the
endurance mileage will also return to normal.
Even if the electric motorcycle is not used, the lithium battery will gradually self discharge, but the
discharge capacity is very small.
In order to ensure the safety of transportation, the outgoing power of lithium battery is about 30%.
Due to the self consumption during the transportation and storage cycle, the first used power is
low or there is no power, which is a normal phenomenon. Please don't worry, just charge
according to the charging instructions.
If the battery is not used for a long time, it will enter the sleep state in order to reduce power
consumption. It needs to be charged by the charger to activate.
WARNING:
Use independent socket for the charger, do not share the socket with electric equipment to avoid
danger and fire.
Do not disassemble or strike the charger. Warranty will not be applicable if consumers disassemble
the charger or there is obvious damage on the charger.
If the lithium battery is deformed or damaged, do not charge it;
Do not charge if the lithium battery terminal is rusty;
If you smell peculiar smell or see smoke during charging, please disconnect the charger immediately
and keep away from the lithium battery (quickly transfer the lithium battery to the outdoor open place
under the absolute safety condition);
When charging, please fully plug the charging plug into the power socket or lithium battery socket;

Controller unlocking
When it is powered on for the first time, the controller is locked. At this time, it is unable to ride and needs to
unlock the controller.
When the vehicle is not riding after the first unlocking, the vehicle will automatically lock after 5 seconds
(ready light goes out). When the vehicle is not riding again, it will still lock again until the vehicle moves.
After the vehicle kicks the side stand (with side stand flameout switch), it is equivalent to turning off the
controller, which needs to be unlocked again.
In the process of riding, if the vehicle stops, the key is not closed, the side stand is not turned on, the
controller is locked after 5S, and the brake needs to be pulled again to unlock.
Battery over temperature protection:
During the ride, if the weather is hot and the heat is emitted by lithium battery during riding, the temperature of
lithium battery may be too high. In order to protect the battery, the output power of the battery will be reduced,
so that the battery will not be ultra high temperature, overload operation and life of the battery will be
prolonged. After power reduction, the vehicle speed will be reduced to about 20km/h. The instrument will light
up the battery warning light until the battery temperature will be lower than the safety range and then recover.
