Always charge the battery in a dry and ventilated environment. Never cover the charger during 
charging process, otherwise it may get damaged. The charger is only for indoor use. 
The charger can be damaged by abnormal exposure to water, shocks, etc. In such case the 
warranty will be void.  
 

 
RIDING INSTRUCTIONS 

 
Before the trip 
1. Choose an open space.  
2. Unfold the e-scooter according to the previous instructions.  
3. Adjust the height of the handlebar. 
 
The trip 
1. Press long the button ON/OFF   , the speed level is set to last used. 
2. You can toggle a different speed level according to the road / traffic conditions. 
3. The e-scooter is preset to the safe-start mode. Place one foot on the deck, push forward with 
the other foot. Then press the throttle gently. Tilt your body forwards during acceleration. To 
gain better stability keep the front foot forwards and the rear foot turned with angle 70-

90° to 

the front one. 
4. If you need to slow down or a person or other obstacles appear in front of you while driving, 
press the brake lever / levers. This disconnects the motor and slows down the e-scooter. 
Always press the rear brake (the left lever) first. While braking, slightly tilt your body backwards 
to protect the frame / handle folding mechanism from excessive wear. 
 
Stopping 
Hold the brake lever to interrupt the engine power and slow down. Before stopping, put one 
foot on the ground. 
Avoid emergency braking to prevent from skidding fall, excessive tire wear or unstable riding. 
 
Warning 
Do not use the e-scooter in the rain or freezing weather bellow -

5°C

 (the trip distance is 

reduced by approx. 30% in temperature 5°C

). If the road is wet, do not exceed the 

speed 10km/h and brake gently to prevent from skidding fall. 
 
 

MAINTENANCE 

 
Tire 
If the tire or inner tube is damaged or worn-out, replace it with a new one. The spare tire or 
inner tube is available at your vendor. Also check the axle bolts every month if they are fixed. 
 
Replacing the tire or inner tube in the rear wheel 
1. Make sure the scooter is disconnected from the charger and the display is off.
