• Para apagar el dispositivo, mantenga pulsado el botón de encendido hasta que la pantalla se apague.

2 Funciones de visualización

The intelligent display shows important information such as speed, battery level, and pedal assist level. Refer to the specific display manual for detailed functions and settings.

3. Sistema de asistencia al pedaleo (PAS)

The Y20 PRO features a 5-level pedal assist system.

• Use the '+' and '-' buttons on the control panel to adjust the assist level.
• Level 0: No electric assistance.
• Nivel 1-5: Increasing levels of motor assistance. Level 1 provides minimal assistance, suitable for low speeds, while Level 5 provides maximum power for steep inclines or higher speeds.
• The motor engages when you start pedaling and disengages when you stop or apply the brakes.

4. Funcionamiento del acelerador (si corresponde)

Your e-bike may be equipped with a throttle for electric-only propulsion.

• Twist the throttle grip to engage the motor without pedaling.
• Nota: In some regions (e.g., Germany), electric-only throttle operation without pedaling may be restricted or prohibited for certain e-bike classifications. Always comply with local regulations.

5. Cambio de marchas

The 7-speed Shimano gear system allows you to adjust your pedaling effort to different terrains.

• Shift gears smoothly by pedaling lightly while operating the shifter.
• Lower gears (larger cogs) are for climbing hills, higher gears (smaller cogs) are for flat terrain and speed.

Mantenimiento

Regular maintenance is crucial for the safety, performance, and longevity of your VAKOLE Y20 PRO electric bicycle.

1. Cuidado de la batería

• Guarde la batería en un lugar fresco y seco, idealmente entre 10 °C y 20 °C (50 °F y 68 °F).
• Do not store the battery fully charged or completely empty for extended periods. Aim for 50-70% charge for long-term storage.

2. Presión de los neumáticos

• Compruebe la presión de los neumáticos antes de cada viaje.
• Maintain pressure within the range indicated on the tire sidewall. Proper inflation improves efficiency and reduces the risk of punctures.
• The 4.0-inch fat tires may require lower pressures for off-road comfort and grip, and higher pressures for road efficiency.

3. Sistema de frenos

• Inspeccione periódicamente las pastillas de freno para detectar desgaste y reemplácelas cuando sea necesario.
• Check brake fluid levels and bleed the hydraulic system if braking feels spongy or inconsistent. This should ideally be done by a qualified bicycle mechanic.
• Asegúrese de que los rotores de freno estén limpios y libres de aceite o grasa.

4. Cadena y transmisión

• Mantenga la cadena limpia y lubricada para garantizar cambios suaves y evitar el desgaste prematuro.
• Inspeccione la cadena, el cassette y el plato para detectar desgaste o daños.
• Adjust the derailleur if shifting becomes imprecise.

5. Limpieza General

• Limpia tu bicicleta eléctrica periódicamente con adamp Paño y jabón suave.
