- Full Electric Mode: Use the thumb throttle to propel the bike without pedaling. This mode consumes battery faster.
- Ручни режим: Возите бицикл као традиционални бицикл без икакве помоћи мотора.
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.
Кочиони систем
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.
