Ninebot S

1）If you have just received a vehicle riding or turning on a smooth indoor road, the tread will cause greater friction with the ground, so abnormal noise will occur. This is a normal phenomenon. You only need to ride on the road for a period of time and fading away.

2) When riding, the hub motor and the guide disc assembly interfere and produce abnormal noise. In this case, reinstall the hub decoration assembly to solve the problem.

3) The wheel will "click Sound" every time turn the vehicle

In this case, it is judged that the hub motor shaft is loose, and it is recommended that the after-sales outlets conduct inspection and maintenance.

The simplest way to re-calibrate the sensors of the Ninebot S is to do a reboot of the system.

To do that, follow these instructions:

1. Delete the Segway-Ninebot app
2. Reboot unit- see procedure below
3. Reinstall app, log in

Keep in mind that this will also erase the Bluetooth password (yes, you can use this to reset your password if you ever forget it), you will need to go into settings and re-enter it.  

• Set the Ninebot S upside down so the standing platform is level but opposite of the normal position

• Keep hair, long clothing, jewelry clear of the wheels
• Press the power button on and continue to hold it down.
• The wheels will rotate about 1/4 turn in alternating directions. **(Please let us know if one or both wheels do not turn, or if one of them is slower than the other.)

After the Ninebot S-Kids is turned on, you can use your mobile phone to search and connect to Bluetooth to play songs.

Note: The Bluetooth for playing voice and the Bluetooth for communication are not the same Bluetooth. The default name of Bluetooth for playing voice is NanoAUD XXXX (with a space in between), and the default name for communication Bluetooth is NanoXXXX (XXXX is the serial number)

This phenomenon is normal, and the app device settings will turn on the alarm for too fast tilt backward speed by default.

The Ninebot S-Kids needs to be connected to the APP to adjust the mode of the hub light in the common functions of the main interface. There are three modes of Single color breathing, full-color breathing, and power follow-up.

As different regions have slightly different policies, please consult relevant local authorities in advance. During product testing, both subways and trains are allowed to carry balance vehicles. Although the battery capacity of the Ninebot S-Kids is 74Wh, it meets the upper limit for air transportation of lithium batteries specified by the Civil Aviation of China.

(160Wh), but the specific rules need to be consulted with the carrier airline.

The Ninebot S-Kids has no anti-theft and positioning functions. Segway-Ninebot APP only has the function of locking the vehicle. After the unit is locked, if other people try to move or ride, the unit will shake and buzzer alarm. However, given the small size of the unit, it is easy for thieves to take it away. The lock function provided in the APP does not truly prevent theft. The best way is to keep it within your own space.

The distance between the Ninebot S-Kids and the Ninebot Travel APP and the Bluetooth of the mobile phone should generally not exceed 10m, and try to avoid the influence of electromagnetic and occlusion in the environment.

The shutdown method is changed to long press the power button for 3 seconds to shut down, to solve the problem that an error message may appear when short press shutdown.

You can update the firmware version of the Ninebot S-Kids, and restart the Unit. If the problem still cannot be solved, you need to contact the after-sales service for repair.

1) If you have just received a vehicle riding or turning on a smooth indoor road, the tread will cause greater friction with the ground, so abnormal noise will occur. This is a normal phenomenon. You only need to ride on the road for a period of time and fading away.

2) When riding, the hub motor and the guide disc assembly interfere and produce abnormal noise. In this case, reinstall the hub decoration assembly to solve the problem.

3) The wheel will "click Sound" every time turn the vehicle

In this case, it is judged that the hub motor shaft is loose, and it is recommended that the after-sales outlets conduct inspection and maintenance.

It may be caused by the disconnection of the hub motor Hall wire or the short circuit of the main control MOS tube, please contact the after-sales service for repair.

First determine the customer's height and weight. If it is within the standard range, the pedal may fail to trigger in this case. Please contact after-sales service 4006070001 for consultation and repair.

When the unit is riding, sometimes resonance occurs in an instant (1s-2s), and shaking is normal. If there is continuous jitter after turning on the unit or riding, it may be caused by other reasons, and you need to contact after-sales service for repair.

The sensitivity can be adjusted under the remote control panel of the mobile phone APP; if the mobile phone has a call coming in, the remote control cannot be continued, and the balance vehicle is in an uncontrolled state.

Note: 1) In order to ensure the safety of remote control vehicles, the motor output power is small in the remote control mode, so the riding will be slower. This is a normal phenomenon.

2) The vehicle is in an uncontrolled state. If it is on a relatively flat road, the vehicle will stop slowly; if the balance vehicle is on a downhill road, the balance vehicle will move along.

It moves downhill until it is stopped by external forces. At this time, the vehicle needs to be controlled manually to avoid damage caused by the balance vehicle moving along the downward slope. Please remotely control the vehicle on an open road with few people and flat roads.

Please prepare a 3mm Allen key to re-tighten the two screws that fix the knee control bar assembly (the two screws you screwed when you received the new vehicle).

When the tread pattern on the tire has worn to the tire scale, you need to contact the after-sales service for tire replacement.

If the unit is turned on and there is a strong sense of current at your feet and the vehicle body is shaking after standing, it is recommended that you repair it. If it only shakes back and forth, it is normal

There are several reasons for this situation:

1) Accelerating violently during riding, the output power of the vehicle has reached the limit, and the torque required for balance can no longer be output.

2) After the vehicle is about to reach the speed limit, the vehicle is pitched back to remind to decelerate, and the player continues to accelerate without decelerating, and the vehicle jumps due to tension.

3) Wet metal edges of the elevator of the unit and excessively high speed bumps can easily cause tires to slip and the vehicle loses balance.

4) New rider tutorial are prone to crash when riding on potholes with poor road conditions. (When going through pits and ridges, you need to bend the knee a little bit, let your knees serve as a certain buffer, and keep the vehicle at the same speed as walking.)

If it is not the above four situations, please contact after-sales service to solve

In order to prevent it from falling off, the rubber plug of the shaft seat of the Ninebot S-Kids has a backing. Remember to remove the backing of the double-sided tape before use.

It is normal to ride a slight deviation to the left/right. Because the knee control bar is not absolutely vertical; the ground is not absolutely horizontal; the diameter of the tires on both sides is not absolutely the same, etc., will affect the vehicle to drive in a straight line, please rest assured to use.

Professional high-power ultrasonic transmitter equipment will cause interference to the electronic gyroscope and accelerometer devices in the MEMS (Micro Electro Mechanical System) system. Leading to deviations in the attitude detection of the interfered device (phenomenon is early tilt backward or automatic steering, etc.).

Note: UAVs, mobile phones, balance vehicles and other devices with MEMS systems inside may be interfered by high-power dedicated equipment and the ultrasonic transmitting equipment in life.

The principle of the balance bike determines that it cannot use mechanical brakes. The center of gravity of the person can be decelerated by backwards. It is necessary to avoid sudden acceleration and rapid acceleration during riding.

1) Please check whether the front and rear wheels are blocked and check whether the mudguards fall off and jam the front wheels, which may cause a big difference in speed due to interference;

2) The speed will decrease in the uphill section;

3) The battery of the balance vehicle is too low to limit the speed.

This is normal. After turning on the unit, lift it up and then put it down. You need to keep the vehicle vertically placed underneath to automatically restore balance. When the vehicle is down or the skew angle is too large, the balance cannot be automatically restored. When the vehicle is tilted and straightened for 1 second, it will be normal.

The following reasons can cause the vehicle to recline during riding:

1) The driving speed of the vehicle is too fast; if the driving speed exceeds the set speed, the vehicle will use the pedal to recline with an alarm sound to remind the rider to slow down. This is a vehicle safety protection mechanism. To ensure personal safety, please do not Speed up;

2) The speed limit of the vehicle; if you feel that the vehicle starts to lean back when the speed is slow, please confirm whether the vehicle is turned on the "safe mode", if the "safe mode" is turned on, you can switch to the "sports mode" in the APP to release the safety Speed limit.

3) The vehicle's battery is too low: check the remaining battery of the vehicle . When the battery is insufficient, there will be different degrees of backwards. This is a normal phenomenon. Please charge it in time.

The possible reasons for this situation are:

1) Uneven road surface;

2) Additional accessories are installed on the vehicle.

Cause the vehicle balance point to drift and move forward or backward (high or low temperature may also cause the balance point to drift), please connect to the Segway-Ninebot APP to adjust the balance point of the boost mode in the sensor settings to reduce or solve the problem you encounter If you still have any questions, you can contact Ninebot after-sales service for testing.
