2.2 Risk of Injury
Whenever you drive the SO2, you risk injury from loss of control, collisions and falls. It is your responsibility to learn how to
safely drive the SO2 in order to reduce the risks of driving.
This manual is designed to help you learn safe driving techniques.
The SO2 must not be used unless the operator has read through and understood the entire manual.
Review this manual frequently to help remind you of proper driving techniques and safety procedures.
2.3 Attention!
There are risks to driving every vehicle. This one is no exception.
Start in a safe location without traffic and have somebody helping you with your first steps and start slowly. If you carefully
follow all the instructions and warnings in this manual, you should be able to teach yourself to drive. Avoid using the SO2 if
you are feeling tired, sleepy or you have a medical condition that reduces your ability to drive.
Please ensure this manual is read and understood beforehand, and do pay extra attention when driving.
1. All users of the SO2 must follow all traffic laws and regulations. Check whether you can use the SO2 on public
property before you drive it there. Especially keep track of pedestrians, children, animals and other road users
when you drive this device.
CAUTION!
WARNING!

2. Both tires must be in contact with the ground at all times. Avoid obstacles and slippery surfaces (such as snow, ice,
oil, sand etc.), which could result in a loss of balance or traction and cause a fall. The SO2 is intended for indoors or
use on smooth, flat surfaces. To prevent loss of traction, you must always be careful when driving and you must
identify and avoid slippery and wet surfaces, loose materials, slopes, tram tracks, potholes and other obstacles
(especially higher than 1 cm). The wheels must be able to grip the ground for you to stay upright.
3. Abrupt maneuvers and driving over slippery surfaces, bumps, and loose objects and materials, as well as
performing jumps and stunts and risky behavior in general, may cause it to lose traction and pose a risk to the
operator and the device and must be avoided therefore. The driving speed must always be adjusted to given
conditions (e.g. light, weather, other traffic participants, etc.).
4. Make sure to wear flat shoes (no high heels) when using the SO2. Ask a person to help you if you are not an
experienced user.
5. The SO2 may not be used by children under the age of 14 in accordance with legal requirements. These legal
requirements comply with German law. Check the relevant local and national laws of your country.
6. Do not exceed the maximum weight of 264 pounds (120 kilograms) –including backpacks and other items that
might be carried. Exceeding the weight limit could lead to injury of the driver and/or the SO2.
7. Never turn off the SO2 while you are riding.
8. Do not modify the SO2. Modifications could interfere with operating and could result in serious injury and/or
damage. Modifications will void the warranty.
9. The SO2 is designed for the use of one person only at a time. It must never be used by more than one person at a
time. Do not carry heavy or spacious objects with you when driving.

10
10. You must wear a complete protection equipment (helmet, kneepads, back protector, etc.) when driving the SO2.
11. Hold the handle-bar tightly with both hands at any time when driving.
12. Always keep both your feet on the SO2 while riding, unless you’re accelerating. Wait until you have come to a
complete standstill before you get off the SO2.
13. Check the brakes before every ride. Never drive with damaged brakes, but contact your official dealer. You can slow
down the scooter by using the break lever on the left side of the handlebar. The brake lever activates both the
electric front brake and the drum brake of the rear wheel at the same time. For safety reasons remove the shown
sticker and the APP verification code (see assembly).
14. Do not use the SO2 in temperatures below -5°C. This can have a negative effect on the battery and the engine.
There is also an increased risk of slipping at these temperatures due to ice formation.
15. Driving in rainy and snowy weather is not recommended. You should also avoid driving through puddles of water
because the water could damage the engine or the electricity.
16. Always keep the device away from humidity, during usage as well as storage (see section 5 “Maintenance, repairs
and warranty”).
17. Always check the battery charge before using the SO2.
18. Never operate any SO2 while under the influence of drugs, alcohol, strong medication or other substances that can
influence your level of attention.

3.3 Battery and charger
The engine of your SO2 is powered by a lithium-ion battery. The SO2 has to be fully charged before its first use. Only
charge the battery in a dry and clean environment. Plug one end of the charger into the socket and then the other end into
your SO2. Now a red light appears which indicates the battery level. The battery is now charging. The first charging cycle
can take up to five hours. The charger will stop the charging process automatically, once the battery has been fully
charged. This is indicated by a green light. When the light changes from red to green, first unplug the charger from the
socket and afterwards from the SO2. Please note that the battery is fully charged as soon as the display shows five bars,
even though one bar seems to be missing.
Do not charge the SO2 without supervision and remove the charger when the charging process is completed.
Never use any other charger than the original one which is delivered with the SO2.
Should you encounter any difficulties during the charging process, please contact your retailer.
If the SO2 is barley used, we recommend to recharge the battery monthly, to ensure its longevity. Before a long pause of
usage, we recommend to fully charge the battery.
WARNING!

14
3.4 Inserting and replacing the battery
It is possible to replace the battery of your SO2. To do this, open the battery compartment with the key and remove the
battery pack. Insert the new battery as shown in the picture below and close the battery compartment again with the key.
3.5 Maintenance
Do not try to charge the SO2 when the battery is already full. This could diminish the battery’s capacity in the long run.
Check all screws before using the SO2, especially those of the handle bar, the brakes and the front- and rear wheel. Ensure
that all screws are tightened before you use the SO2.
Thoroughly clean the SO2 with a dry cloth after usage. The front and rear ball bearings must be lubricated from time to
time. Ordinary bicycle oil can be used. Oil the area where the axle runs into the wheel to ensure better durability.

15
3.6 IP54
The SO2 is splash-proof according to IP54 but not waterproof. You may therefore use the SO2 in light rain and drive
through puddles on the ground. You must not immerse the SO2 in water or expose it to heavy rain, otherwise the
electronics may be damaged. Further information about the scope of protection according to IP 54 can be found on the
Internet.
4. Driving instructions
4.1 Operation
First, turn on your SO2 by pressing and holding the start button for 2 seconds. You can accelerate with the SO2 by pushing
your foot against the ground with one leg and accelerating the device (as with a conventional scooter). Alternatively, you
can accelerate by operating the gas lever on the right side of the handlebar.
The left brake lever operates the rear brake. Shift your body weight to the rear to compensate for the braking effect of the
engine brake. This allows safe and controlled braking. In addition, you can operate the brake lever on the right side to
activate the front brake. Always be careful when using the front brake. When using the front brake, it is advisable to apply
the rear brake at the same time to achieve even braking.

4.5 Road traffic regulation of Germany
Your SO2 is approved for road use, but insurance must still be taken out with the data confirmation sheet. The insurance
sticker must be affixed to the back in the area below the light. Only then may you drive on the road. If you take part in road
traffic with the scooter, your SO2 is subject to the local traffic regulations like any other vehicle. Before taking your SO2 to
the street, make sure you have read and understood the following paragraphs (Status as of 31.08.2019) carefully. Check
