4.1 Řazení rychlostních stupňů
Your VIRIBUS Hybrid Bicycle features a 7-speed Shimano derailleur for smooth and accurate gear changes. Use the thumb shifter on the handlebar to select your desired gear. Shift to a lower gear for climbing hills and a higher gear for flat terrain or descents.

4.2 Brzdění
The bicycle is equipped with dual disc brakes for reliable stopping power in various weather conditions. Apply both front and rear brakes simultaneously for controlled deceleration. Avoid sudden, hard braking with only the front brake, especially at high speeds, as this can cause loss of control.

4.3 Nastavení sedadla
The saddle height can be adjusted to fit riders between 5'3" and 5'9" (Medium size). To adjust, open the quick-release lever on the seat post clamp, move the saddle to the desired height, and firmly close the quick-release lever. Ensure the seat post is inserted past the minimum insertion line.
