- Once moving, gently press the accelerator lever (throttle) on the handlebar.
- Place your second foot on the footboard.
- Maintain balance and steer by gently leaning and turning the handlebars.
Braking
To slow down or stop, gently squeeze the brake lever located on the handlebar. Apply gradual pressure to avoid sudden stops. The scooter may also feature a rear fender brake for additional stopping power.
Folding/Unfolding
The scooter features a folding mechanism for portability and storage.

- To Unfold: Release the latch from the rear fender, lift the handlebar stem upwards until it clicks securely into its upright position, and engage the safety lock.
Maintenance
Cleaning
Wipe the scooter with a damp cloth after use. Do not use high-pressure water jets or immerse the scooter in water, as this can damage electronic components.

Battery Care
- Charge the battery regularly, even if not in use, to maintain battery health.

- Store the scooter in a cool, dry place when not in use for extended periods.
Storage
When storing the scooter for long periods, ensure it is clean and the battery is charged to approximately 50-70%. Store in a dry environment away from direct sunlight and extreme temperatures.
