1.3.2 Transportation mode
After unpack and take out the kick scooter,
1) There is a transportation mode that designed to keep healthy battery during long time
transportation to avoid over-discharge.
2) Turn on the Transportation Mode: it is operated by the IOT App ;
3) Turn off the Transportation Mode: Plug the charger, charging longer than 3 seconds to turn on the
scooter, and transportation mode is turned off. Your Scooter is in working mode.
4) Scooters need to be in transportation mode during long term storage.
1.3.3 Learning to ride
1. Wear an approved helmet and other protective gear to minimize any possible injury; and stand on the
footrest with one foot and push off with another foot to start riding.
2. With an initial speed no lower than 2.5mph and press the throttle to start the scooter, sport mode with
maximum speed of 15.5mph, and it also can be customized for local customer’s actual speed
requirement. To turn, shift your body weight and turn the handle slightly.
3. Press the throttle on the right hand to speed up when you are balanced, and slow down by releasing
the throttle. The electrical brake is integrated in the mechanical brake handlbar, when press the brake,

3.5 Firmware Update
Customers should
1) Keep the firmware up to date through the backend management system “Dashboard” or mobile app
Launcher.
2) Talk to Segway Discovery Engineer to find out an alternative way of upgrade
3) Report problems to customer service.
4. Safety issues
4.1Safety on riding
4) When in riding, do not ride the kick scooter in the rain. Do not get wet. Keep your speed between 5-10km/h.
When you ride through speed bumps, elevator door, bumpy roads or other uneven surfaces. Slightly bend
your knee to better adjust mentioned surfaces.

12 / 14
5) Do not keep your feet on the rear fender; avoid contacting obstacles with the tire/wheel.
6) Do not ride on public roads, motorways or high ways; do not rotate the handle violently while driving at high
speed.
7) Do not carry heavy objects on the handle bar; do not ride the kick scooter with one foot.

13 / 14
8) Do not ride through puddles or any other (water) obstacles. In such a case please lower your speed and
bypass the obstacles, and do not carry any passengers, and do not carry a child, and do not ride when
pregnant.
9) Do not touch the hub motor after riding because it can get hot.
4.2 Design Requirement
The controller can read the battery temperature from Battery Management System, and the BMS can limit the
highest battery output current (Bus Current); Two Temperature Sensors are on the surface of the battery cell.
i) Battery Cell Maximum surface temperature is safe below 158 ˚F（70℃）;
ii) If the cell surface temperature < +107.6 ˚F（42℃）, the maximum Bus Current is 25A
iii) If the cell surface temperature reaches 107 ˚F（42℃）, start to reduce the maximum current
iv) If the cell surface temperature reaches 122 ˚F（50℃）, the output maximum current reduces to 6A.
v) If the cell surface temperature reaches < 14˚F （-10℃）， BMS will turn off the battery output. When
the battery is shut down, the scooter loses the power.
vi) There is 41 ˚F（5℃） temperature difference designed in buffer between the Shut Down temperature
and the Battery Cell Maximum Surface Temperature.
vii) When the controller receives the BMS feedback with the temperature out of the range of -4 ˚F ~ +158
˚F（-20℃~70℃）, the system will prompt the error code 39#, indicating that the BMS temperature is
reported incorrectly, or over-temperature cut off function failure. And If the battery is shut down,
even when the temperature falls back under 149 ˚F（65℃）, the system does not boot automatically.
When the scooter is rebooted again, and the error code 39# will be disappeared.
Remark: We recommend stopping operating when the Ambient Temperature is over 104˚F(40℃).

4.3 Safety on battery
1）No disassembling, squeezing, puncturing the kick scooter; no touching the contact pots; no disassembling or
puncturing the battery case; do not put the kick scooter in the water/fire (including the cooking range,
heating, and other heat resource.) or expose it in the temperature which is higher than 122℉（ 50℃）or is lower
than -4℉（-20℃）（e.g., do not put the battery or the kick scooter exposed in the car in the sun when in
summer）. And please avoid the metal object contacts the battery contact pots to cause the short circuit, and
it will cause the battery damaged or the injury.
2）It will cause the internal circuit damaged if the battery is in water and even cause the possibility of explosion,
and please do not use the battery immediately and contact our CSE.
3）The kick scooter can only use the original battery, and the battery can only use the original charger, or else it
will cause the damage or fire.
Undeserved disposition of waste and useless battery will cause the heavy environment pollution. And please
follow the local regulations on waste and useless battery. Please do not throw away the battery, and
protect natural environment together.
