WindRunner™ self-balancing electric vehicle user manual

1. Introduction of WindRunner™

1.1 How do a WindRunner work?

The WindRunner™ is a dual-wheel self-balanceable electrically operated vehicle, a revolutionary

ride-instead-of-walk and recreational tool. The driver may operate the movement of WindRunner by standing on

it, and shifting his/her body. The WindRunner itself may automatically keep balance and the driver does not have

to worry about the risk of falling.

With the built-in electronic gyro, the on-board high speed CPU may calculate in 200 times/s whether the

mainframe of WindRunner is balanced forward and backward or not. If not, the CPU may control the motor on both

left and right sides to rotate rapidly, and keep the WindRunner balanced. The self-balancing function, allows the

driver to stand on the WindRunner with his body inclined forward. The mainframe may automatically enable its

wheels to move forward, and the WindRunner will move forward; and vice versa. Simply turn the handle left and

right.

Because the balance of WindRunner™ completely depends on the good functioning of a high speed CPU,

precision gyro, and motor, if any one of them has troubles, the WindRunner may lose balance. The WindRunner™

has a hot back-up dual-redundant control system which ensures that all key circuit systems shall be doubled.

Therefore, if any one of the key modules fails to work, the backup may be put into operation so as to maximize the

safe riding.

WindRunner™ self-balancing electric vehicle user manual

2.5 Test riding

Now you have installed the WindRunner properly, and primarily understand the intelligent remote keys.

Please take the following steps before test riding:

1) Stand beside or behind the WindRunner. Keep the foot mat at a basic level position. Hold the handle with

one hand, and press the

“ON/OFF” of intelligent remote key for 1s with the other hand and the WindRunner

shall start. 5 LEDs on the central display panel shall come on in sequence, meanwhile, accompanied with vibration

and buzz similar to that of starting the engine of a car. After the buzz disappears, the WindRunner self-test will be

complete. Keep the foot mat basically leveled then tap any one foot mat lightly with your foot. You may hear a very

short buzz, and then the wheels of WindRunner begin to move, and enter into the power assistant mode.

At the moment of startup, keep the WindRunner upright, and the

foot mat basically leveled with the operating bar at middle

position. Otherwise the intelligent self-test logic may determine

that the WindRunner is unsuitable for starting and unable to

start. Refer to 5.4 for details.

2) Under power assistant mode, you may slowly push the operating bar forward or backward, the WindRunner

repair.

WindRunner™ self-balancing electric vehicle user’s manual

3. Operating modes

The WindRunner has been provided with different operating modes; good understanding and using may be

helpful for your better riding.

3.1Standby mode

The standby mode means that the WindRunner has been started, but doesn’t have any movement, or

balancing ability. The WindRunner shall be in standby mode under the following situations:

 After powered on, the WindRunner shall be in standby mode. If no any other operations happen within

10 minutes, the WindRunner will automatically powered off.

 If the WindRunner is tilted too high under power assistant mode (overexert etc), speed is too high

(beyond 6km/h), handle released and free sliding speed too high, the WindRunner shall determine that it is

unmanned and this can lead to potential hazards. Firstly, it shall give a vibration, audio alarm, automatically cut

off the power output, and enter the standby mode. Just then, if the operating bar is not held, the WindRunner shall

lose its balance and shutdown.

 If the inclined angle of the WindRunner under balance mode is too high (overexert etc at the moment

of acceleration and deceleration), overload (e.g., riding on a sharp slope), internal circuit overheated or battery

capacity fully used up etc, the WindRunner shall firstly give a vibration, and then buzz alarm 4～5s. If the driver

WindRunner™ self-balancing electric vehicle user manual

has not gotten off or reduced his/her speed and load within 4～5s, the WindRunner will enter standby mode and

the rider may fall off.

3.2 Power assistant mode

The power assistant mode means that the WindRunner has been started, and the driver has not gotten-on, but

the movement by tracting the operating bar. Under the power assistant mode, the WindRunner shall output its

power about 30% and move slowly. This operating mode is suitable for handling or shifting the WindRunner, See

5.11 for details. The WindRunner shall be in the power assistant mode under the following situations:

 After powered on, and foot mat basically leveled, tap any one foot mat lightly with your foot. You may

hear a very short buzz, and then the wheels of WindRunner will begin to move and enter the power assistant

mode.

 After riding, take your foot off the foot mat. You may hear a very short buzz, and then the WindRunner

will change from balance mode to power assistant mode.

WindRunner™ self-balancing electric vehicle user’s manual

If required to enter the power assistant mode under powered on,

only tap the foot mat once lightly with your foot. If not on, do not

push on the foot mat always with heavy thing or foot. This may

enable the WindRunner wrongly deem that you have got on and

thus, the WindRunner will enter balance mode, which may be

very possible to cause a loss of control, and eventually lead to

serious damage or hurt.

3.3 Balance mode

Once you stand on the WindRunner, the WindRunner will begin working, and enter balance mode. Balance

mode is convenient for operating and riding on different road conditions. The balance mode consists of beginner

mode, Speed limit mode and normal mode.

The WindRunner has four foot-on mat sensors to detect whether the driver has got on. All four sensors have

the same function, once the WindRunner sensors that anyone is on, it will detect that the WindRunner is manned.

It may enter balance mode. For all four sensors arranged on both sides, even if the driver rose one foot during

riding, it may give no influences to the test.

The Speed limit mode is one of the balance modes, suitable for the driver operating under complicated road

conditions (for example, too much pedestrian or uneven surface of path). While in beginner mode, press the

WindRunner™ self-balancing electric vehicle user’s manual

“Speed limit” button on the intelligent remote key. You may hear a very short buzz or “tick”, and the red LED

at the lowest part of display panel will change into blue and glow steadily. This means that the Speed limit mode

is entered. Under this operating mode, the maximum speed of WindRunner is between beginner mode and

balance mode for complicated road conditions.

3.3.3 Normal mode- 20km/h max

The normal mode is another balance mode, suitable for experienced drivers on good road conditions (e.g., no

pedestrian and even path). This mode may be applicable for riding WindRunner. Under the Speed limit mode,

press the “Speed limit” button on the intelligent remote key. You may hear a very short buzz or “tick”, and the

blue LED at the lowest part of display panel will cut off. This means that the normal mode is entered. Under this

normal mode, the WindRunner has the maximum speed, and highest sensitivity. Press the “Speed limit” button of

intelligent remote key to toggle between beginner mode, Speed limit mode and normal mode.

The max speed you can reach depends on battery stamina,

bodyweight, surface condition and ambient temperature.

Typically, the max speed of Windrunner will be 18~22km/h.

WindRunner™ self-balancing electric vehicle user manual

The built-in intelligent system of WindRunner shall try to ensure

the driver’s safety. However, it cannot ensure to solve problems

associated with long-time overload, over-temperature, low

battery stamina, wheel skidding, etc. Under balance mode, the

WindRunner may begin to shake and alarm, if the driver pays no

attention, within a few seconds, it may be changed to standby

mode and cut off the power output. Just then if the driver is still

on the WindRunner, the driver may crash and get injured.

3.4 Lock mode

The lock mode is a security function of WindRunner under the power on state for temporary short parking to

protect it against traction by others. Under the power on state, press “lock” on the intelligent remote key to

enter the lock mode. After locked up, press “ON/OFF” button to unlock.

All above mentioned working modes shall be further detailed in

4. Stand center of gravity, and slowly shift your body onto the foot mat and raise the other foot.

5. At this moment, try to avoid the transverse moving of the operating bar. Raise the other foot slowly from the

ground surface and place it on the foot mat. Keep in mind that you are standing on the flat surface of the ground.

You should believe in the balancing ability of the WindRunner. Be calm, relax, and look straight ahead. The

sequence of get-on posture is shown in the figure below.

WindRunner™ self-balancing electric vehicle user’s manual

Keep relax, it will be easier to learn how to ride the bike. Some

people may sway involuntarily during their first ride on the

WindRunner. Please keep your muscles relax, remain balanced,

and request your instructor to help you hold the handle. After a

while, you will adapt to riding the WindRunner and you will no

longer sway.

5.6 Move forward and backward

1. Slowly lean forward, and feel the advancement of the WindRunner. Then lean back, feel the deceleration, and

stop. Control its speed. Repeat several times to ensure control of the movement of the WindRunner, and also, the

placement of your body at the center of gravity.

go backward balancing go forward avoid any swaying

WindRunner™ self-balancing electric vehicle user manual

For a new rider, make sure you remain relaxed, and ride the

WindRunner gently. The more relax you remain, the less swaying

you will experience. Avoid swaying or any sudden shift of your

body as the center of gravity. This will help you to avoid sudden

skidding, or falling.

2. Turn your head around to look, and let your body slowly lean backward to reverse the WindRunner. Then

reset. You may feel the deceleration and stop of the WindRunner. Repeat several times. Avoid collisions, and you

will avoid falling.

Reverse riding is not a normal riding mode. There is no

substitution for advancing, unless the rider has to move

backwards to reverse. Otherwise, please not reverse riding. You

may reverse by turn back, then ride forward. If the reverse speed

is too high, the WindRunner will shake and give the buzz alarm.

5.7 Decelerate and stop

Shift the center of gravity of the driver’s weight opposite of the direction of moving to decelerate and stop the

WindRunner. Follow the methods as followed:

WindRunner™ self-balancing electric vehicle user’s manual

1. When you go forward, gently shift your buttocks back (as if you are ready for seating backward) to

decelerate and stop the WindRunner.

2. After you’ve completely stopped, uniformly distribute your body’s weight onto the center of the foot mat to

stabilize. At this moment, if you continue to incline backward, then the WindRunner shall move backward.

3. Specify a point to practice stopping the WindRunner and keeping stability.

Typical decelerating and stopping action

WindRunner™ self-balancing electric vehicle user manual

Try to decelerate and stop gently and progressively. Also, try to

reduce sharp stops. Move back the weight of driver’s body gently

from the moving direction to slowly stop the WindRunner.

During deceleration and stopping, try to avoid wet and slippery

roads because a sharp stop on it may cause the WindRunner and

tires to skid and thus, the driver may fall or get injured!

5.8 Make a turn

The WindRunner shall turn according to the motion of your handle. Inclining your handle left or right may

cause the WindRunner to turn to the corresponding directions.

1. Firstly do exercises of turning at any safe site for riding. Slowly incline your handle to the direction you want

to move, and the WindRunner shall turn at site until the angle you required is achieved. Then, return the handle

back to its normal position. Repeat to turn left and right to master this skill.

WindRunner™ self-balancing electric vehicle user’s manual

Turn right at site turn left at site make a turn in moving

2. Make a turn in moving. After you have become familiarized with the go forward, go backward and turn at site,

try to advance slowly and make a turn. Keep your knees slightly bent, and incline to the direction you want to

make a turn. The angle shall be consistent with that of the operating bar. Repeat until you master this skill.

No matter at site or moving, making a sharp turn is very

dangerous. It can easily cause you to lose balance and fall. So,

please decelerate, and ride slowly at the moment of making a

turn.

 If the WindRunner gives the low-voltage alarm, shakes, or shows a Speed limit, it means that the power

has been approximately used up. At this moment, it may still work for about 1-3km, or 2-6km under

WindRunner™ self-balancing electric vehicle user’s manual

power assistant mode. If you continue to ride for long period, it is unsafe, and may possibly cause the

battery to over-discharge. Which, may reduce the capacity & cycle life of the battery.

 Only use the built-in battery charger of WindRunner or certified charger from Ninebot. Do not use any other

chargers. Otherwise the service life of battery may be reduced, or the battery may be damaged.

 If a battery has been out of normal work or Ninebot’s authorized service shop have found that its condition

is not good, we strongly recommend that you replace the battery by pair. A new battery together with a battery

that may be expired may greatly reduce the service life of the new one and the riding performances of

WindRunner——for safety reasons, the performances of WindRunner depend on the worst one of all the 2

batteries.

 If you find the battery pack is cracked, leaked, seriously heated or you smell an abnormal smell,

immediately stop using the WindRunner, remove the battery immediately, and contact the Ninebot authorized

agent or distributor for information. If the battery leaked, you must wear plastic gloves before handle it, to protect

your skin against injury.

If you do not follow the battery using instructions hereof, the life

cycle, safety, stamina may be significantly reduced. That’s not

quality defect and not covered by the Limited Warranty.

7.4 Transport and recycle of the battery pack

WindRunner™ self-balancing electric vehicle user manual

The Chinese laws and regulations only allow the aviation enterprise to transport the lithium ion battery pack

not exceed 160Wh capacity, so the aviation is not applicable for transporting the battery pack of a WindRunner.

So, you must transport the battery pack by truck or train, and firstly consult the transport company. For other

countries and regions similar with restrictive regulations, please contact the local carrier companies for details.

If you want to ship a battery, please pack the battery with thick poly-foam and corrugated paper box. Make

sure the package is strong, sold and water tight.

8. Routine maintenance

8.1 Keep cleanness

 Please clean your WindRunner immediately after use.

Periodically clean to keep the optimum performances of the

WindRunner.

 During cleaning, you may wipe the mainframe of WindRunner

with a soft cloth soaked in clean water.

 It is forbidden to use alcohol, gasoline, kerosene, acetone or other corrosive chemical solvents to clean the

WindRunner. All the above may cause surface damage, internal part failure, and warranty qualification loss.

WindRunner™ self-balancing electric vehicle user’s manual

 Wash the tire and fender with a household shower or water pipe, but avoid direct spraying to the mainframe.

After washed, leach and dry as soon as possible, store the WindRunner in a well-ventilated place to dry. This will

protect some steel component parts against rust.

 Remove the foot mat and wash it with clean water.

When cleaning the WindRunner, ensure that the WindRunner is

powered-off, and charging cable is detached, and the charge port

is tightly covered by the rubber cap! Otherwise you may suffer an

electric shock or serious troubles.

It is strictly forbidden to directly spray and wash the WindRunner

with a water hose and head used for washing car. Do not wholly

soak the WindRunner in water. This may cause serious damage

due to the moisture or water accumulated inside it.

8.2 Check whether the screw is loose or not

Periodically check the assemblies such as hub, operating bar, battery pack, fender, and housing of display

panel etc. Shake lightly to observe whether the assembly is shaking or loose; if loose, please check the

corresponding screws, and retighten with the accompanied tools.

WindRunner™ self-balancing electric vehicle user manual

8.3 Check the inflation pressure of tire

In general, the pressure of the tire of the WindRunner G1U urban type is kept at 10～15PSI, and the maximum

up to 30PSI; and that of all terrain type G1X shall be kept at 5

～

8PSI, the maximum up to 12PSI. Higher pressure

of the tire may reduce its friction resistance, thus increase the battery stamina. Lower inflation pressure of the tire

may reduce the battery stamina—but relatively comfortable on the rugged and uneven road. The pressure of a tire

too high or too low may speed up the wearing of the tire.

8.4 Storage

Please store indoor, dry and normal temperature.

Try to control the storage temperature at 0

℃

～30℃

, the room

temperature storage is favorable for prolonging the service life of battery and

other component parts.

8.5 handling

Please handle the WindRunner appropriately, and obey the steps as following:

 Ensure the WindRunner is not connected to the charging cable, and is powered off.

 If you want to put the WindRunner into a narrow and small space (such as the luggage compartment of car

etc), please firstly loosen the quick-release handle of WindRunner operating bar, remove the whole operating bar,

and respectively handle the mainframe and operating bar.

WindRunner™ self-balancing electric vehicle user’s manual

 The mainframe is relatively heavy. Please request the help of another person.

 Please keep hands in the correct position when handling the battery pack or hub.

At the moment of handling, please grasp the hub with hands, not

the fender, otherwise the fender may be damaged, and possibly

injure your hands.

8.6 Repair

Apart from retightening the screw, replacing the tire, fender, and battery; no other component parts of the

WindRunner can be repaired by the users themselves. If you find any unsolvable problems, please contact us, or

our authorized service agents.

Apart from service engineers authorized by Ninebot, no one else

is permit to disassemble the WindRunner; otherwise the

Warranty will be void. Ninebot and its agents will not be

responsible for any losses in these cases.

9. Troubles and alarms

9.1 FAQs and troubleshooting

1, Unable to power on:

 Please verify whether the battery of intelligent remote key has sufficient capacity, or retest the power after

the battery is replaced. If powered on only when the intelligent remote key is quite close to mainframe, it means

that the battery of the intelligent remote key has been approximately used up and you are now required to replace

the battery. (consult 4.5 of this manual)

 If the battery of the intelligent remote key has enough battery capacity but is still unable to power on, then

it may be caused by the power of the WindRunner battery being fully used up. It may also refer to an internal

circuit failure. Please retest only after the WindRunner is fully charged. If still unable to power on after it has been

fully charged (refer to 7.2 of this manual), please contact the local agent/distributor for repair.

 During normal riding, if the WindRunner is unable to power on after automatically being powered off, or if

there is a high resistance felt during traction of WindRunner, then it is probably caused by internal motor riding

circuit failure. To prevent short-circuiting of the battery, the user should remove both batteries as soon as possible.

Do not hesitate to contact the factory for repair.

2, After powered on, alarm or red LED continuously flickered:

WindRunner™ self-balancing electric vehicle user’s manual

 If able to power on, but you hear the alarm only after powered on, this means that the WindRunner has not

passed the power on self-test power on self-test. The detailed trouble information is related to LED state, so

please consult the 9.2 alarm information code list to verify the problem and solving method. For troubles you are

unable to solve by yourself, please contact the local agent/distributor for repair.

3, The WindRunner spins by itself without control:

 In some cases (typically if the ambient temperature changes), the WindRunner will spin slowly without

moving the operate bar, or the mainframe will pitch when rider turns left/right. This shows the internal sensors

need re-calibration. Please perform the following steps:

 Power on. Let the WindRunner lean on solid wall(keep it totally stationary), press "Lock"

button on the remote key to enter lock mode, then press "Battery Indication" button

4 times. This will enter the gyroscope calibration program and you will hear beep and

see the blue LED shows on in sequence. Wait 3 seconds, the blue LEDs will be off

which indicates the balancing sensor assembly calibration is done.

 When in lock mode, press the "Speed Limit" key 4 times. This will enter the turning

sensor calibration program and you will hear beep and see the blue LED shows on in

sequence. Wait 1 second, the blue LEDs will be off, the turning sensor calibration is

done.

WindRunner™ self-balancing electric vehicle user manual

 when calibration procedure is done, press ON/OFF button, quit lock mode and you can

ride.

 If there is still same problem after the temperature compensation, please repeat the compensation

steps mentioned above.

 YOU MUST KEEP THE WINDRUNNER STILL DURING THE WHOLE COMPENSATION PROCEDURE. OR THE

COMPENSATION SHALL FAIL.

4, During normal riding, sudden alarms, Speed limits, and accompanying acute shaking:

 The intelligent safety alarm system may be activated, or the internal safety system test may have found

hardware trouble (including one of the hot back-up systems failed). This is usually caused by too high temperature,

a heavy load, unsafe riding methods, or hardware failure detected while riding the WindRunner. Please consult 9.2

trouble code lists for details of troubles. If unable to solve by yourself, please contact the local agent/distributor

for repair.

9.2 List of alarm information codes

If any troubles arise (or intelligent safety alarm is activated), the lamps on WindRunner shall continuously

flicker. This will be accompanied with alarm sound, and an acute shake in the mainframe. While riding, if any

troubles arise or intelligent safety alarm is activated, the WindRunner will forcibly decelerate, and you will

Appendix A. More maintenance instructions

A.1 Replace the tire

Replace the tire after worn to a specified extent. The user may purchase

the special-purpose tire and then replace by his or herself. You can also

replace the tire at an Ninebot authorized agent/distributor. For G1U urban

type, if the tire pattern is worn up to a furrow less than 2mm deep, or

scratched or failed, renew as soon as possible to ensure high safety. For G1X

all terrain type, if the salient discontinuous pattern at the apex of tread is worn

and invisible, or the tire is swelt, scratched, or defects are found, renew it.

WindRunner™ self-balancing electric vehicle user’s manual

For replacing the tire, only pull out the decorative cap of hub, and remove the five lock nuts with sleeve. Then,

take out the tire. The right figure is an illustration for replacing tire. (take G1U urban type as an example. It is

similar to the replacement of an all terrain type tire.)

A.2 Replace the fender

If the fender is damaged, the user may replace it on his or her own. You can also replace it at an Ninebot

authorized agent and distributor. The figure below shows an illustration for replacing the fender.

1. First turn the mainframe sideway. Then, after the tires are removed, hold down the front and rear decorative

strips. Unscrew the two screws of fender but do not remove.

2. Unscrew the four screws for fixing the fender and place on the gearbox. Then raise the fender.

WindRunner™ self-balancing electric vehicle user’s manual

A.4 replace the gear oil

About every 2000km of the total mileage (charged 80~120 times),please replace the gear oil. The steps are

as followed:

1. Dismantle the tire.

2. Vertically place the mainframe of the WindRunner to pump out the gear oil.

WindRunner™ self-balancing electric vehicle user manual

3. Remove the oil hole sealing bolt as shown in the figure. Care to keep the O-rings of screws.

4. Use a clean injector with a needle >Ф1mm to insert into the bottom of oil hole. Slowly suck up the gear oil.

Repeat this step until no gear oil is left.

5. Refill 120~150ml new gear oil .( 75W or GL-4 gear oil for motorcycle or car).

6. Check whether the O-ring is in good conditions or not. Put the O-ring onto the oil hole sealing bolt, and

tighten it.

Apart from the battery pack, tire, fender, foot mat, gear oil and

operating bar, all other parts of mainframe can’t be

maintained or repaired by the user. It is strictly forbidden to

loosen or remove the chassis cover plate screws or any other

parts without authorization. Otherwise, it may cause poor

waterproof performances, serious damage, or accidents!

WindRunner™ self-balancing electric vehicle user’s manual

Appendix B. Deep understanding WindRunner

B.1 Battery stamina and battery indication

Factors affecting the battery stamina

For the same set of batteries under different service conditions, after charged, its stamina may be quite

different. The followings are some factors affecting the stamina:

 Try to ride under moderate speed (12～16km/h) to prolong the stamina of the battery once charged.

Frequently accelerate and decelerate. Low-speed riding and maximum speed riding may shorten the stamina of

the battery once charged.

 Riding at 10

℃

～25℃

may get the maximum stamina for the chemical properties of the lithium battery. Riding

under low temperature or high temperature may decrease the optimum stamina.

 The nominal mileage of the WindRunner battery is determined under the carrying capacity of 70kg (including

the driver and luggage). The higher the weight of the driver, the lower the stamina of battery. On the contrary, the

lower the weight of the driver, the longer the stamina of the battery.

WindRunner™ self-balancing electric vehicle user manual

 An uphill slope may quickly shorten the stamina of a battery, but a downhill slope may prolong the stamina

of a battery. Under extreme conditions, a gentle slope of a continuous several kilometers may charge quite a great

amount of the battery capacity.

 Rugged and uneven road surface may shorten the stamina of a battery, but a flat and smooth road surface

may prolong the stamina of a battery.

 Check the tire pressure of the WindRunner. Usually the tire of the WindRunner G1U urban type is 10

～

15PSI,

and that of all terrain type G1X 5～8PSI. The higher the tire pressure, the lower the friction resistance. Thus

prolong the stamina of battery, lower the tire pressure, and lessen the stamina of battery—but it may be

comfortable on a rugged and uneven path.

Accuracy of battery indication

 The WindRunner has five LEDs for indicating the battery capacity. Though, these are a rough means for

indicating the capacity of the battery.

 Because the power required for riding the WindRunner varies greatly (for example, only about 300W

required for uniform motion on flat and smooth road surface, but accelerate on a steep slope may require 2000W),

it is difficult to have an accurate indication of the battery capacity. The user shall try to avoid acute acceleration

with battery capacity less than 50% or moving on a complicated land form. Try to avoid moving uphill for long

periods at a time.

WindRunner™ self-balancing electric vehicle user’s manual

 The properties of a battery may vary gradually with frequent use. So the battery indication may be

inaccurate after a period of time. To ensure high safety, the battery capacity of WindRunner has a redundant

safety margin. When the battery indication has only one division, the WindRunner begins its Speed limit and shake

alarm. The battery is actually 10%

～

30% left. For safety reasons, also keep an eye out for battery discharge. If

you do all of these things, the life cycle of the battery may be prolonged.

B.2 Tire and land form

 The tire pattern and land form have an adaptability and compatibility relationship. Moreover, the

performances of the tire used for suitable or unsuitable land forms vary greatly.

 The tire of the WindRunner G1U urban type is suitable for common urban road conditions such as asphalt

road, cement road, glazed tile and brick road, rigid leveled earthy roads, etc. Under these service conditions, G1U

urban type may award the best riding experiences, and optimum tire adherence effect, and optimum battery

stamina. But the all terrain type is lower efficiency on urban road, so the battery stamina is relatively lower, and

the tire may be worn more rapidly.

 The pattern of tire for the WindRunner G1U all terrain type is applicable for grassland, earthy slope, forest

land, and muddy/rugged mountainous road. On these road situations, G1X all terrain type may reach its optimum

shock-absorbing effect, and optimum tire adherence effect. Although G1U urban type may be also rode on some

rugged and uneven road with difficulty, its tires will have poor adherence, lower safety and shock-absorbing effect

than that of all terrain type tire. So more caution should be considered when riding.

WindRunner™ self-balancing electric vehicle user manual

B.3 About intelligent Speed limit

 The WindRunner has adopted the battery capacity based intelligent Speed limit algorithm. According to

different battery conditions (cycle times/ battery ageing, residual battery capacity), the internal processor of the

WindRunner may automatically determine the maximum Speed limit value.

 In good conditions, if the battery capacity is >60%, the WindRunner may continuously ride under balance

mode- normal mode in a speed slightly higher than 20km/h.

 In good conditions, if the battery capacity is <60%, the maximum Speed limit of the WindRunner may be

reduced gradually with the reducing of battery capacity.

 If the capacity of any one of both batteries is <10%, the WindRunner shall give a low-voltage alarm buzz,

mainframe shake, and the foot mat will face-up greatly to warn the driver to get off and charge as soon as possible.

Under these situations, it is unsafe to continue riding.

 If the ambient temperature is detected to be to low(<-10 ) or too high (>40 ) at the

℃ ℃

moment the

WindRunner is powered on, the intelligent Speed limit of the WindRunner shall also function. Just then, even if the

battery capacity is full, the maximum speed may be unable to reach. To ensure high safety, the detailed Speed

limit depends on the WindRunner’s internal intelligent Speed limit algorithm.

WindRunner™ self-balancing electric vehicle user’s manual

B.4 Hot back-up safety mechanism

 Several key components of the WindRunner have the hot back-up safety mechanism to maximize the

guarantee of the driver’s safety.

 Hot back-up battery pack: both battery packs are used together, one for operating, and one for standby. If

one battery pack fails, powers off, or disengaged, it may not cause accidents. Reason being, the WindRunner may

immediately detect the exceptions of the battery pack, and decelerate immediately. The shaking mainframe will

give the alarm buzz and warn the driver to get off.

 Hot back-up posture sensor unit: the posture sensor unit is the core of the WindRunner. If the posture sensor

unit fails and does not work while riding, a serious accident may be possibly happen. To ensure safety, two sets

of individual posture sensor units are provided. Through a unique control algorithm, if any one sets out of function,

the system may avoid serious accidents such as over turn, etc. The WindRunner will immediately decelerate. The

mainframe will shake give an alarm buzz, and warn the driver to get off.

 Hot back-up power subsystem: the WindRunner has a great amount of built-in micro-electronic devices,

which require the converter for power supply. The micro-electronic chip (IC) has very low failure rate. However,

if partial power fails, the system will power off. Then all the hot back-up design shall lose its significance. So two

sets of power supplies were provided. Any one set may be sufficient for support of the whole system individually.

If one set of the power supply system fails, the system may immediately detect trouble, and immediately

decelerate. The mainframe will shake, give an alarm buzz, and warn the driver to get off.

WindRunner™ self-balancing electric vehicle user manual

 It should be noted that the hot back-up technology can’t give the guarantee of 100% safety. For example,

both gearbox and tire are unable to provide the hot back-up. The hot back-up design may only try to improve the

safety of the WindRunner. This is neither a guarantee for free troubles such as tire burst, nor a guarantee for

skidding of tire. Strictly obey chapter VI “Safe riding instruction” for a better guarantee of safety protection.

B.5 G1X and G1U upgrading mode

 The WindRunner G1U urban type may be upgraded into G1X all terrain type by replacing the tire and fender

assembly by updating the control program firmware. The G1X all terrain type may also be upgraded into G1U

urban type. In the future, the Ninebot shall provide the upgrading service through the authorized

agent/distributor step by step. Please do not hesitate to contact Ninebot.

B.6 Brake lights

 All WindRunner’s are equipped with standard LED brake lights. Under dark conditions, the red and

eye-catching brake lights may greatly reduce the possibility of rear-end collision.

 The brake lights are unable to be controlled by the user. Only by the built-in intelligent algorithm. The brake

lights shall come on at the moment of decelerating or downhill journey. The driver may ignore when the brake

lights come on.
