4.3 Gear Shifting (7-Speed)

The 7-speed gear system allows you to adjust pedaling effort for different inclines and speeds.

• Use the shifter on the right handlebar to change gears.
• Shift to lower gears (larger cogs) for easier pedaling on inclines.
• Shift to higher gears (smaller cogs) for faster speeds on flat terrain.
• Always pedal lightly when shifting gears for smooth transitions and to prevent damage to the drivetrain.

4.4 Braking System

The ES9 is equipped with dual hydraulic disc brakes for reliable stopping power.

• The right lever controls the rear brake, and the left lever controls the front brake.
• Apply both brakes simultaneously for optimal stopping performance and control.
• Avoid sudden, hard braking, especially with the front brake, to prevent skidding.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your electric bike.
