Funcionament
The Mongoose Colton Mountain Bike is designed for trail riding and general cycling. Understanding its features will enhance your riding experience.
Gear Shifting (7-Speed)
Your bike is equipped with a 7-speed drivetrain featuring a trigger shifter. The trigger shifter allows for quick and precise gear changes.
- Canvi de marxes ascendents: Use the larger lever on the right shifter to shift to a higher gear (harder to pedal, faster speed).
- Canvi de marxa a la baixa: Use the smaller lever on the right shifter to shift to a lower gear (easier to pedal, slower speed).
- Shift gears smoothly by pedaling lightly while shifting. Avoid shifting under heavy load.

Figure 3: Handlebars and Controls. This image shows the ergonomic design of the handlebars, including the trigger shifters and brake levers for easy access during rides.
Frens de disc mecànics
The mechanical disc brakes provide reliable stopping power in various conditions.
- The left lever controls the front brake, and the right lever controls the rear brake.
- Apply both brakes simultaneously for effective and controlled stopping.
- Avoid sudden, hard braking, especially with the front brake, as this can lead to loss of control.
