6Safety Instruction
We recommend always wearing helmet and protective gear like elbow, knee and wrist
protectors to ensure your personal safety.
Also make sure you have read the user manual carefully, to ensure you know how to ride it
in a safe and fun way.
The Electric scooter is for domestic use only.
It is your responsibility to be aware of and comply with all regulations. If there are no
regulations for this Electric scooter in your country, please take care of your own safety
and the safety of others.
Also pay attention to other people. Always ride safely and only at a speed that allows you
to brake safely at any time. A common thing for such products is that there is a risk that
you may fall off the product and injure yourself. Always ride as safely as possible.
If lending the electric scooter to friends and family, please make sure they use proper
protective gear and know how to ride it.
Before riding the electric scooter, please check that all parts are working as supposed to.
If any loose parts, abnormal noise, reduced battery life etc. are detected, please contact
your retailer for product service and warranty. Do not repair the electric scooter yourself.
Inspect the rear tire, rear brake, and brake pad according to Section 7 of the maintenance
specification in this operating instructions. The electric scooter may become unstable if the
rear brake is deformed or loose. This is because the distance between the brake pad and
the rear wheel becomes too small, possibly leading to a blocked rear wheel.
Avoid applying too much force or stepping on the rear fender permanently. This may
cause the fender to loosen or damage the spring holding the fender.
As a result, the brake pad constantly touches the wheel and the motor temperature
increases due to the additional resistance. The rear tire can also get loose if the brake is in
constant braking position.
Avoid constant braking. As a result, the tires will not only wear off, but also become hot.
This will soften the rubber and it will no longer have the same grip on the road as usual.
Do not touch the tire after braking.
If you hear unusual noises or notice friction when switching on the electric scooter, a
bearing may be damaged. A worn bearing may even be indicated by strong vibration of the

8
handlebar. In this case, please contact your retailer since the bearing needs to be replaced
and/or the handlebar checked and adjusted.
Ride the electric scooter only on a dry surface since otherwise the riding safety and
braking performance may be impaired and the motor or bearings may be damaged.
Please do not ride up or down long and steep slopes.
Stop riding when you receive the "Low Battery Warning". The electric scooter then moves
only slowly and does not have the same traction as normal and the electric brake does not
work. In this case, please use the rear brake to stop the electric scooter. Get off the Electric
scooter as soon as the speed allows to do that safely.
Do not use the electric brake and the throttle at the same time.
A normally working Electric scooter operates safely and quietly. If you hear noises or
notice bumpy operation, please check wheels, bearings, and brakes. Contact your customer
service for repair and maintenance, if necessary.
7Maintenance
To ensure you get the best possible performance and experience from your electric
scooter, it is important to do regular maintenance for important parts of the
product.
●Battery maintenance
●Bearings, Screws, Brakes and Wheels
●Storage and Cleaning
Your electric scooter will require some maintenance so please read and familiarize
yourself with this guide.
●Battery maintenance
All batteries have a life cycle, and performance will decrease over time, however here
are some advice to maximize the life span of the battery.
Make sure that the battery is charged at regular intervals, even if you do not use the
electric scooter for a long time. This is to prevent damage to the battery, caused by low
voltage over an extended period.
Avoid draining the battery completely. It is best to charge while there is still power on it.
This will extend battery life. If the battery is constantly depleted, it will damage the battery
(damaged battery caused by wrong handling are not covered by the warranty).
If riding the electric scooter in cold or very hot areas, the battery time can be lower than
when riding in temperatures from 15‐25° Celsius. This is not a failure on the batteries, but
normal behavior.
Please notice: Even a fully charged battery will run out of power if the electric scooter is
not used for a period. Expect a fully charged battery to keep power between 90 and 120

9
days in off mode, before it is fully discharged. If only partially charged, this period is
lower.
Please make sure the battery does not get above 50°Celsius, or below minus 10°Celsius
for a longer period. (e.g. don’t leave the electric scooter in a hot car in summer, do not put
battery into fire etc.) Low temperature (e.g. subzero temperature) can damage the battery
cells.
Keep the Electric scooter away from open flame or other sources of heat to prevent the
battery from getting too hot. Also make sure not to leave the electric scooter at freezing
temperatures. Both heat and excessive cold can cause the battery to discharge.
Only use original charger or an official replacement, as different batteries may require
specific charger, and if using other chargers, this could cause damage to the product.
Do not overcharge and discharge the battery.
Please make sure to charge the battery before it is completely out of power, to avoid
damaging the battery cells. (damaged battery caused by wrong handling are not covered by
the warranty)
It is forbidden to disassemble battery package. This is only to be handled by official
service repair centers and professionals.
●Bearings, Screws, brakes and Wheels
Your electric scooter is made up of moving parts, which in time, will be susceptible to
wear and tear.
Bearings and screws:
The electric scooter has sealed and dustproof bearings so that no lubrication is required.
Check the bearings for wear at regular intervals to avoid unsafe riding. Do not jump on
and off and do not apply excessive force otherwise to avoid damage to the bearings. This
is not a sports electric scooter.
Make sure that all screws are properly tightened to avoid unsafe situations.
Please check the screws regularly and tighten if they seem loose.
Brakes:
Check the brake for wear at regular intervals to avoid unsafe riding. Do not apply
excessive force to avoid damage to the brake.
Wheels:
Check the wheels for wear at regular intervals to avoid unsafe riding.
Electric scooters come with different wheels but can in general be separated into tires with
inflatable inner tubes and solid wheels.
For inflatable tires, please make sure to keep the right pressure, as hard tires will last
longer.

If the wheel seems wobbly even after screws are tightened, the bearings might
be worn down and need replacement
