Gear Shifting (Shimano 8-Speed)

Your bike is equipped with a Shimano 8-speed drivetrain for efficient pedaling across different terrains.

• Use the shifter on the right handlebar to change gears.
• Shift to a lower gear (larger cog on the rear wheel) for easier pedaling on inclines.
• Shift to a higher gear (smaller cog on the rear wheel) for faster speeds on flat or downhill sections.
• Always pedal lightly when shifting gears to ensure smooth transitions and prevent damage to the drivetrain.

Braking (V-Brakes)

The bike features V-brakes on both the front and rear wheels.

• The right lever controls the rear brake, and the left lever controls the front brake.
• Apply both brakes simultaneously for controlled stopping.
• Avoid sudden, hard application of the front brake, especially at high speeds, as this can cause loss of control.

Brake and Gear Adjustment

• בראַקעס: Ensure brake levers engage smoothly and the brake pads make full contact with the wheel rim. Adjust cable tension if brakes feel too loose or too tight.
• גירז: If shifting becomes rough or gears skip, the derailleur may need adjustment. Consult a professional bike mechanic if you are unsure.
