The cycle is equipped with Shimano 7-speed gears for adapting to various terrains.

Figura 6.2: Close-up of the rear wheel showing the Shimano 7-speed gears and the Bafang hub motor, which provides electric assistance.
Use the gear shifter on the handlebar to change gears. Shift to lower gears for climbing hills and higher gears for flat terrain or descents. Always shift gears while pedaling lightly to ensure smooth transitions and prevent damage to the drivetrain.
6.4 Sistema de freos
The Acer Momentum features dual mechanical disc brakes for reliable stopping power.
- The left brake lever typically controls the front wheel brake.
- The right brake lever typically controls the rear wheel brake.
- Apply both brakes simultaneously and gradually for controlled stopping. Avoid sudden, hard braking, especially with the front brake, to prevent skidding.
6.5 Hydraulic Suspension
The front hydraulic suspension enhances comfort on varied surfaces.

Figura 6.3: Detail of the front hydraulic telescopic suspension, designed to absorb shocks and provide a smoother ride.
The suspension can be locked out for more efficient pedaling on smooth roads or unlocked for absorbing shocks on rougher terrain. Refer to the suspension fork manufacturer's instructions for specific adjustment procedures.
