5.2 Riding Modes
Your ASKGO F28 Electric Bike offers multiple riding modes:

5.3 Gear Shifting
The 7-speed gear system allows you to adjust your pedaling effort to match terrain and speed. Use the gear shifter on the handlebar to change gears. Shift to lower gears for climbing hills and higher gears for flat terrain or downhill riding.
5.4 Braking
The bike is equipped with mechanical disc brakes. Apply both front and rear brakes simultaneously for effective and controlled stopping. Avoid sudden, hard braking, especially with the front brake, to prevent loss of control.
6. Battery Information
