Located under the frame, mounted on the self-balancing vehicle foot pad.

5mm short hex wrench (adjust the length of the frame), 4mm long hex wrench (remove the knee control) and 2.5mm small hex wrench (install the rear spoiler).

The attached engine speaker can be connected to the vehicle to simulate four kinds of sound effects. It can also be connected to the mobile phone through Bluetooth to make a Bluetooth speaker.

1. Gokart Pro is not a means of transportation. Please abide by local laws, regulations and policies when driving.

2. Please start smoothly on a flat road and do not exceed the speed limit. Please do not accelerate or slow down suddenly or brake sharply. Please do not exceed Gokart’s limiting speed of driving, otherwise there is a risk of loss of control, collision.

3. In order to reduce the risk of injury, please fasten your seat belt before driving. Please stay alert while driving and keep good judgment. Drive at a proper speed, keep a safe distance from other vehicles at all times, and slow down when entering unfamiliar surroundings.

The front wheel is non-inflatable hollow tire, tire width 80mm, flat ratio 60%. The rear tire width is 68mm, 10 × 2.75 inch, hollow solid tire.

Ninebot Gokart Pro machine protection level is IPX4. It is prohibited to ride outside in rainy days, for your personal safety, it is not recommended to ride outside in any other bad weather.

Ninebot Gokart Pro appearance plastic parts are mainly made of PC materials, including PC+ABS, PP, PA6+GF and other materials. The frame is made of steel.

Every Gokart Pro will be tested that all functions are normal before leaving the factory. Only allowed to leave the factory to ensure that each product meets Ninebot quality standards. Therefore, the slight dirt / wear of the tire is caused by the road test. It is not a quality problem and is not a refurbished product. Please feel free to use it.

a. With both hands holding the steering wheel and the seat, stretch the frame out to a suitable position along the horizontal direction of the connection tube.

b. Align the scalable structure of the frame with the marking on the connection tube.

c. Positioning: Use the short hex wrench (on the left side of the seat) to press the two screws into the holes on the left and right connection tube in order. (The screw is set to a depth of about 1 cm for successful position)

d .Tighten the 4 screws.

In order to prevent overturns from causing sharp turning, the chassis is designed to be low, with a minimum ground height of 40mm. It is recommended that the driver get off the vehicle and push the vehicle over the speed reduction belt to avoid hitting the chassis to damage the vehicle.

Due to the collision prevention during transportation, the Gokart Pro will be tight when it shrinks to the minimum state. It is recommended that two people pull the front and rear frames with their hands.

Because the Gokart Mode requires higher rear tire friction, so it is necessary to release a part of the rear tire air, at this time will not rub the handbrake and the rear tire friction is the optimal state.

The front cabin indicator may not be ON because the front circuit board is not powered on. The cause may be because of:

a. Forget to install 6 No.5 dry batteries, install the batteries.

b. Power extension cable is not connected, or the power extension cable is loose, reconnect them.

It can be solved by following below process：

a. Check whether the tires of the Ninebot Max are worn out. If so, replace the tire.

b. Check if the handbrake spring is deformed. If so, replace the handbrake spring；

c. Tighten the screws on the bottom of the brake lever.

Please follow the steps below to adjust：

a. Adjust the length of the steering rod to about 232mm to solve the wheel skew.

b. Reinstall the left and right hub assemblies.

After the two screws are loosened, the black hexagonal connecting rod can be tightened to fine-tune the steering system. After adjusting, tighten the screws.

If the test drive has just been completed, it may be caused by the adapter pad not being in place and suddenly falling when riding; while acceleration and deceleration “squeaking” sounds is there that because there is a certain gap between the adapter pad and the Ninebot Max. Back-and-forth shaking will inevitably cause vibration, which will not affect normal use. Try to avoid rapid acceleration and deceleration; choose a flat road surface to reduce this situation.

As the front wheel is non-inflatable hollow tire, the tire width is 80mm and the flatness ratio is 60%. The contact area with the ground is large, so it is easy to be worn. The service life of the front tire is relatively low, but it can still be used for about 800km. If you find that the tires are damaged, we recommend that you should contact Ninebot after sales service to purchase the front tire for replacement.

Unfolding Dimension（Max）：1420 × 852 × 600mm；Folding Dimension（Min）：1040 × 852 × 459mm；Packaging size：1140*905*510mm（Cardboard structure packaging scheme）

Net weight: about 51.2kg; Max load: 100kg. Ninebot Max weight: about 21kg.

Working Ambient Temperature -10℃—40℃；Ambient Storage Temperature -20℃—50℃.

The waterproof rating of Ninebot Max is IP54. Outdoor riding and wading are prohibited in rainy days. For your personal safety, outdoor riding is not recommended in other bad weather.

If the car is not powered off after riding, the alarm will beep after 10 minutes, and it will become more and more rapid. Then it will automatically power off to save energy, and the Max body may lose its balance and fall down.

Ninebot Max uses non-inflatable solid tires, which do not need to be pumped up.

The light switch can be set in the App. Please confirm that the light switch has been turned on in the App.

Viewing method: After connecting the vehicle with App, click on the upper left corner of the main page - Light effect Settings – turn on the required light effect.

In addition, the headlight is an induction lamp, which only lights up when the external environment is dark. Therefore, it will not light up if the headlight is turned on in the App during the day when there is sufficient light.

If the attitude sensor of the self-balancing vehicle is not in the horizontal state, it shall be operated according to one of the following methods:

1. Connect the vehicle with the mobile App, enter "Setting" - "Sensor Setting" and click "Attitude Sensor calibration", perform sensor calibration as prompted, and power on the vehicle again to check whether it is restored to balance.

2. Stand the vehicle upside down, put the foam leg pad on the ground, press the power button to start the vehicle, wait 2-3 seconds, you will hear a "beep", and then immediately hear two "beep" indicating that the vehicle calibration is complete (Note: this operation will be used when the sensor calibration fails).

If the above cannot remove the fault, please contact after-sales for repair.

This is a normal phenomenon. After powering on, lift it up and then put it down. The balance can be automatically restored only when the vehicle is put down vertically. When the vehicle is lying down or the deviation Angle is too large, the balance cannot be automatically restored.

here are several reasons for the vehicle to tilt backward during riding:

1) Caused by excessively fast riding speed. When the driving speed is over or close to 20km/h, the vehicle tilts backward by the pedal with an alarm sound to prompt the driver to slow down, which is a vehicle safety protection mechanism. In order to ensure personal safety, please do not drive excessive speed or accelerate sharply.

2) Due to excessive acceleration of the vehicle, when the center of gravity leans forward more than 5°, the vehicle will tilt backward through the pedal with an alarm sound to prompt the driver to slow down acceleration, which is a vehicle safety protection mechanism. In order to ensure personal safety, please do not accelerate rapidly.

3) Speed limit for vehicles. If you feel that the vehicle starts to tilt backward when the speed is slow, please confirm whether the "speed limit mode" is turned on. To confirm, please check whether the "speed limit" sign on the vehicle dashboard is steady on. If it is steady on, please turn off the speed limit mode in the App.

4) The low electric power of the vehicle leads to this phenomenon. Check the remaining electric power of the vehicle. When the electric power is less than 30%, there will be different amplitude of leaning back, which is a normal phenomenon. Please charge it in time.

This is because the direction of the vehicle is reversed. Please confirm the direction of the vehicle when getting on the vehicle (the side with the display panel is the front).

Check as follows:

1) Confirm that the connection between the knee control and the vehicle body is not loose;

2) Ensure that the vehicle has been successfully activated and is not in speed limiting mode;

3) Open the App to connect the vehicle on the setting page, check "Steering sensitivity" in "Sensor Settings" and set it to "Automatic" mode.

If the above methods cannot be solved, you need to contact the after-sales service for repair.

This phenomenon is a normal, adding backward alarm and brake light display is to avoid the operator reverse driving the self-balancing vehicle.

The principle of self-balancing vehicle determines that it is impossible to have mechanical brake. Therefore, when the speed reaches the upper limit, the center of gravity can be shifted backward to achieve the purpose of slowing down. During riding, it is necessary to avoid violent pedal warping caused by rapid acceleration.

The firmware version of the vehicle body should be updated first, and power on and off again. If the problem still cannot be solved, please contact the after-sales service 4006070001 for repair.

Connect the vehicle to the App to adjust the balance point, the operation procedure: click the upper left corner of the main page - Device settings - Sensor settings - Assist mode balance point, the positive direction represents the vehicle leaning forward, the negative direction represents the vehicle leaning back, adjust according to your actual needs. Or power on the vehicle upside down for 3 seconds, and then turn it on upright.

Gokart Pro has four driving modes. After the vehicle is connected to the App, scroll down to the “Mode selection” on the app home page to switch.

Safe Mode (Maximum Speed: 8km / H);

New Rider Mode (Maximum Speed: 18km / H);

Sport Mode (Maximum Speed: 24km / H);

Track Mode (Maximum Speed: 40km / H)

After completing all the beginner tutorial, you can unlock the Maximum speed of 18km/h through the App Setting Novice Mode, and when the cumulative driving range exceeds 1000 meters, you can set the Maximum speed mode through the App.

If the self-balancing vehicle does not switch to "Gokart Mode", it will cause moving forward/back due to the center of gravity in front/facing backward after powering on. And Gokart Pro cannot be upgraded, the throttle and brake will not operate. Before assembling Gokart Pro, please perform the following operations on the self-balancing vehicle:

1) Open the App, search and connect your self-balancing vehicle.

2) App interface upper left corner – “Mode selection” – “Gokart Mode”. On self-balancing vehicle settings page, click "Gokart Mode" and power it on.

Note: It is forbidden to sit on the self-balancing vehicle without upgrading it separately to prevent injuries caused by sudden acceleration resulting from the balance point of the self-balancing vehicle that is too offset.

The light switch can be set in the Segway-Ninebot App, you need to confirm that the light switch has been turned on in the App.

Viewing method: After the mobile app connects to the vehicle, click the upper left corner of the home page - Lighting effect settings - turn on the desired lighting effect. The headlight is an induction light, which will only be lit when the external environment is dark, so when the ambient brightness is sufficient during the day, the headlight will not be lit when the front light is turned on in the App.

The taillight needs to be connected with App to the self-balancing vehicle to adjust the ambient light switch and mode.

1. Open the App and connect the self-balancing vehicle.

2. Click the R/C icon.

3. Drag the virtual handle to control your self-balancing vehicle.

* Do not ride when the self-balancing vehicle is set to R/C Mode. Riding may cause serious injury or serious damage to the vehicle. In R/C mode, the Maximum speed is 7km/h, but you can adjust the Maximum speed through the App. The Bluetooth connection range of the self-balancing vehicle is 10-15 meters. Out of Bluetooth connection range, R/C mode will automatically disconnect.

For your first time using Gokart Pro, there will be a Beginner tutorial on Segway-Ninebot App. Please follow the prompts to do activation operation.

Please perform the prompts in Segway-Ninebot App to upgrade the Gokart Pro firmware;

Firmware upgrading will improve the use of the vehicle as well as fix related bugs.

a. App cannot switch the mode of the self-balancing vehicle when connected to the Gokart Pro, so the connection between the self-balancing vehicle and the Gokart should be disconnected first.

b. App searches and reconnects the self-balancing vehicle and can switch to Balancing vehicle mode in Settings.

There is an error in the reference GPS mileage comparison. This is normal phenomenon. The actual riding conditions are not ideal, and there will be differences in driving mileage.

If the Bluetooth connection fails: there is a high probability of poor Bluetooth adaptation of Samsung / Huawei mobile phones, please try to connect your mobile phone close to the middle cabin again; replace other mainstream phone models and try again.

If the new rider tutorial cannot be downloaded and the Gokart Pro initialization fails. First, switch the network to ensure smooth network. Then reinstall Segway-Ninebot App or change your mobile phone to try again. If still cannot be solved, please contact Ninebot after-sales service 4006070001 for consultation.

Since the new vehicle is not activated, it is in the speed limit state. You need to download App and connect your S-Max to activate it before it can be used. The unactivated S-Max will appear continuous "beep" alarm during startup and use.

Two kinds of deceleration mode:

Mechanical braking -- Pull the handbrake up;

Electronic braking -- Press the brake pedal with your left foot.

Unstable throttle acceleration power output is mainly caused by two reasons:

a When riding for a long time, the battery temperature will gradually increase, the vehicle will trigger the power protection mechanism, the output power will decrease, and the power to step on the accelerator will become weak.

b When you drive the GoKart Pro continuously, the overcurrent protection mechanism will be triggered, and the output power will decrease for 5-10s, after which the power output returns to normal.

The Ninebot Max is in "Gokart Pro Mode", so it cannot ride normally. After connecting to the App, you will be prompted to exit the "Gokart Pro Mode". Click OK to exit. If not prompted, enter the setting interface and switch it to “Balancing Vehicle Mode” manually.

There are several reasons for this:

1.Please check whether there is something stuck in the front and rear wheels, and check whether the front fender fall off and jammed in the front wheel, which causes interference and leads to big difference in speed.

2. Speed slows down on uphill sections.

3.Too low battery of S-Max causing speed limit.

Gokart Pro brake standard is 75kg for test riders, 20km / h, and asphalt road. It is normal to have a brake distance about 6 meters when left foot is pressed to the bottom of the brake. And the manual brake handle is emergency braking. Pulling the brake handle can immediately achieve the braking effect. If the braking distance is too long and fails in this condition, it can be judged as abnormal, and you may need to contact the after-sales service.

1. The blue indicator blinks alternately. Please remove the 6 dry batteries of Gokart Pro and reinstall it. The reason was that the mid-cabin control board entered the dead cycle state by mistake;

2. Dry battery voltage is low or dead, please replace all 6 dry batteries. Be careful not to mix different brands, old and new batteries, to avoid failure to start or restart.

3. After the Gokart Pro locks, the throttle & brake will not respond, the purpose is to ensure the safety of riding and just unlock it.

If the accelerator and brake suddenly fail in the middle of driving, please immediately pull the manual brake handle, emergency brake or shut down as soon as possible. Check the status of the Gokart Pro and the Ninebot Max and contact Ninebot after-sales service 4006070001 for solution.

This is normal. Gokart Pro cannot idling, so there must be a speed difference during idling. When there is a difference in motor speed, it is possible that one will not rotate. The control board only controls the average speed of the two wheels.

Drift / S-bend Intermittent output may cause battery overcurrent protection. Please avoid frequent and violent operations, which may cause battery damage. If you suddenly shut down and restart, you can use it normally.

Drift / S-bend Intermittent output may cause battery overcurrent protection. Please avoid frequent and violent operations, which may cause battery damage. If you suddenly shut down and restart, you can use it normally.

The serial port communication status is intermittent. Please check whether the connection between the Gokart Pro kit and the Ninebot Max is tight, whether the exposed communication cable is worn or whether the front cabin indicator light is yellow or red. If you find any abnormalities, please contact Ninebot after-sales service 4006070001.

Over-speeding or rapid acceleration of the vehicle during riding can lead to loss of balance or power failure. The working principle of the self-balancing vehicle is to monitor the state of the vehicle in real time by the built-in electronic gyroscope. When the human body leans forward or backward, the vehicle will immediately drive the wheels to rotate, generating a reaction force to maintain the balance of the vehicle. When over speed or rapid acceleration, the human body will instantly lean forward, bringing pressure that requires the vehicle to provide a huge amount of power to maintain at the same time, thus there is a risk of power failure due to insufficient power output. Be sure to drive gently.

It may be caused by the shed of the Hall line of the wheel motor or the short circuit of control board mos tube, which needs to contact the after-sales service for repair.

Confirm the height and weight, children are too light that sometimes cannot trigger the foot switch, if the values are within the standard range, this situation may be the bowl switch elasticity is poor so that the foot trigger failure, need to contact the after-sales service for repair.

When the vehicle is at a high speed, sometimes resonance will occur in a moment about (1s-2s), and shaking is a normal phenomenon. If the shaking occurs for a long time at high speed, contact the after-sales service for repair.

If the app prompts overheating protection, if the temperature exceeds 60 ° C, the vehicle will be accompanied by an alarm. Please place the vehicle in a cool and ventilated place to quickly dissipate the heat and release the alarm. The vehicle temperature can be used normally when the temperature is lower than 40 ℃.

You can check the remaining battery power of the kit on the App interface, or judge the remaining battery power of the vehicle through the power indicator light.

Gokart Pro is powered by a self-balancing vehicle, and its service time is affected by the driver's weight, road conditions, weather and driving speed.

Charging indicator light: When the charger is energized, the red light flashes; when charging, the red light is steady on; when fully charged, the red light goes out.

This is the battery overheating protection, battery/vehicle body temperature over 40℃ cannot be charged, wait to stand below 40℃ to restore normal. It is forbidden to use for a long time (after using one battery, shut it down until it is completely cooled).

Follow the following steps to troubleshoot:

a.Troubleshoot whether there is poor contact: re-plug the connections on both sides of the charger to see if it can be solved.

b. Check whether the charging cable is faulty: connect the charging cable to the power supply without connecting the battery, observe whether the charger's indicator light flashes (red). If it does not light up, it means the charger is faulty and needs to contact the after-sales service for repair.

c. Check whether the charger indicator is red in the charging state, if the indicator is not lit, the charger may be faulty or the battery may be damaged, you need to contact the after-sales service for repair.

d. The battery may overheat after a ride and cannot be charged at this time. Allow a little time to cool down and then plug in the charger to charge.

The 6 dry batteries can be theoretically use about 28 hours. Because the battery capacity of different brands of dry batteries are different and the use time will also vary.

Gokart Pro cannot be powered on as defined is that after the Gokart Pro and the Ninebot Max are assembled, press the Ninebot Max power button to power it on. The Gokart Pro buzzer has no "beep" starting sound, and the white decorative light and color indicator light are off. The mobile App can only search for the Bluetooth of the Ninebot Max, but cannot search for the Bluetooth of the Gokart Pro.

The reasons that caused the Gokart Pro to fail to power on are.

a. Gokart Pro battery is low or installed incorrectlY.

b. The wired connection of the Gokart Pro and the Ninebot Max is not connected, or the connector is not plugged in;

c. The connection between the Gokart Pro and the Ninebot Max is damaged and blocked;

d. Gokart Pro hardware failure.

Troubleshooting Method: First check if the power supply of the Gokart Pro is normal. If it is normal, check whether the cable between the Gokart Pro and the Ninebot Max is smooth. If it is unblocked, return and check whether the Gokart Pro hardware is faulty.

a. The dry batteries are exhausted, causing the Gokart Pro to fail to start. Replace 6 dry batteries;

b. Control board fault, causing Gokart Pro to fail to start, replace front cabin control board;

c. Battery over-current protection causes automatic shutdown, just turn the unit off and on, and follow the instructions to avoid severe battery damage caused by frequent over-current protection;

* Automatically shut down and cannot be turned on during or after use, the power chip of the Ninebot Max of A02, A05 may break down. Unplug the serial communication cable and check the power ON/OFF status of the Ninebot Max. If the fault is confirmed, contact the corresponding after-sales service.

About 3-4 hours.

Ninebot Max uses a lithium-ion battery, which takes about 7 hours to charge, and the battery life can be maintained at more than 60% of its capacity for 500 times of normal charging and discharging.

Note: Battery life is closely related to daily use habits, avoid charging when the power is completely exhausted, try to use as you go, avoid using or storing the battery in environments below -20°C or above 50°C, when not in use for more than 30 days, please fill the battery and place it in a cool and dry place for storage. Ensure that it is charged once every 90 days, this will greatly extend the battery life.

Failure to charge may be caused by poor contact or battery over discharge/charger damage, please follow the following methods to troubleshoot:

1) Check whether the charger interface is in good contact with the vehicle body interface;

2) If the battery is slightly over-discharged, keep charging for more than 1 hour and then observe whether it is charging normally;

If it cannot restore normal charging, please contact after-sales service for repair.

1) Battery over discharge: the vehicle has not been charged for a long time, the battery over discharge leads to the inability to power on.

If the fault persists, contact the after-sales service for advice and repair.

1. How to solve the abnormal sound "creak" around the knee control?

The lower end of the knee control assembly is not tight with the quick release, and there is loosening phenomenon, so there will be abnormal sound in use;

Note: In case of loosening, please use 2.5mm tool to tighten the two hex socket screws in the red circle below, do not tighten them too tightly (or will cause the quick release cannot be installed), tighten them until they are not loose, then install the knee control rod and try to turn left and right again. If the abnormal sound decreases, you can tighten them until the abnormal sound disappears.

If the fastening still not remove the fault, need to contact after-sales repair.

3. Abnormal sound generated by acceleration and deceleration of vehicles/riding at high speed.

When customers ride at a speed of acceleration and deceleration or at a relatively high speed, the vehicle will first convey a sense of vibration to the customers, and then accompanied by the sound of high-frequency impact of plastic parts. At this time, we suggest that the customers return to the Repair outlets or attach damping foams on both sides of the front and rear decorative strips.
