- Rėmo išskleidimas: Carefully unfold the main frame of the bike until it locks into place. Ensure the folding mechanism is securely latched.
- Vairo montavimas: Insert the handlebar stem into the fork tube and tighten the quick-release lever or bolts as instructed. Ensure the handlebar is aligned with the front wheel.

Važiavimo režimai
- Pedalų pagalbos režimas (PAS): The motor provides assistance as you pedal. Adjust the assist level using the display controls (usually '+' and '-' buttons). Higher levels provide more assistance.
- Pilnai elektrinis režimas: Use the thumb throttle to propel the bike without pedaling. This mode consumes battery faster.
- Rankinis režimas: Važiuokite dviračiu kaip įprastu dviračiu be jokios variklio pagalbos.
Gears and Shifting
The F20 PRO is equipped with a 7-speed derailleur system. Use the gear shifter on the handlebar to change gears according to terrain and desired pedaling effort. Shift gears smoothly by easing off the pedals slightly during the shift.
Stabdžių sistema
The bike features front and rear mechanical 160mm disc brakes with power-off brake levers. Squeeze both brake levers simultaneously for effective and safe stopping. The power-off feature cuts motor power when brakes are applied.

Priežiūra
Regular maintenance is crucial for the longevity and safe operation of your Fafrees F20 PRO Electric Bike.
- Valymas: Reguliariai valykite dviratį naudodami reklamąamp šluoste. Venkite naudoti aukšto slėgio plovimo įrenginius tiesiai ant elektrinių komponentų.
- Tepimas: Lubricate the chain and other moving parts (e.g., derailleur pivots) periodically with bicycle-specific lubricant.
- Padangos: Check tire pressure before each ride. The recommended pressure is usually indicated on the tire sidewall. Inspect tires for wear and damage.
- Stabdžiai: Regularly check brake pads for wear and ensure brake levers provide firm and responsive stopping power. Adjust brake cables as needed.
- Akumuliatoriaus priežiūra:
- Charge the battery fully after each ride, especially if it's been significantly discharged.
- Bateriją laikykite vėsioje, sausoje vietoje, toliau nuo tiesioginių saulės spindulių ir ekstremalių temperatūrų.
- If storing the bike for an extended period, charge the battery to 50-70% every 1-2 months.
- Tvirtinimo detalės: Periodiškai patikrinkite visų varžtų, veržlių ir greito atjungimo mechanizmų tvirtumą.
