ARE YOU READY? – BEFORE RIDING

Before riding:

Ensure the steering system and folding system are working properly
Make sure all components are tightly secured
Check that the wheel axle is fastened to the body
Confirm the wheel rotates normally
Confirm the brake system works normally
Check tyre pressure before riding
Recommended tyre pressure: 45–50 psi
Check wear of the tyres and brake pads
If wear is serious and replacement is needed, contact the dealer promptly

RIDING THE SCOOTER

Turn on the power and check the power indicator.
Stand on the pedal with one foot and push back with the other foot.
When the scooter is sliding, place both feet stably on the pedal and gently press the throttle twistgrip.
The throttle starts working above 4 km/h.
Release the throttle twistgrip and use energy recovery to decelerate.
Emergency braking requires a powerful grip on both sides of the brake levers.
During turns, the body should lean slightly in the direction of the turn, and the handlebar should be turned slowly.

Additional riding notes

The risk of fall injuries is present during practice
Wear a helmet and protectors throughout practice
Deceleration can be adjusted through energy recovery in the app

RIDING SAFETY

The manual’s riding safety section includes these points:

Read the manual carefully before riding
Follow local laws and regulations
The scooter is both a transportation and recreational tool
Ride in relatively closed and flat road environments where possible
Stay alert and keep proper speed
Maintain a safe distance from others and vehicles
Be aware of surroundings and ride slowly on unfamiliar terrain
Respect pedestrians’ right of way
Alert pedestrians when passing from behind
Slow down when passing pedestrians
Pass pedestrians from the left where applicable
When facing pedestrians, keep right and slow down
Take time to learn the basics to avoid serious accidents in the first months

Additional safety notes

Do not lend the scooter to someone who cannot operate it safely
Before lending it to others, make sure the rider has read the manual and learned the novice guidance
Remind riders to wear a helmet and protectors
Before each ride, check the condition of the scooter
Stop using it if parts are loose, damaged, tyres are flat or excessively worn, battery life decreases significantly, or the scooter shows abnormal noises or alarms
Keep the original packaging in case return or repair is needed in the future
If non-original packaging is used, responsibility for transport damage and related extra logistics costs remains with the user
