5.1 Riding the Bicycle
Familiarize yourself with the bicycle in a safe, open area before riding in traffic. Always maintain control and be prepared to brake.
5.2 Gear Shifting (Shimano Nexus 3-Speed)

Figure 4: The Shimano Nexus 3-speed hub gear system provides smooth and reliable shifting.
- The PACTO Eleven is equipped with a Shimano Nexus 3-speed internal gear hub.
- Shift gears using the twist shifter on the handlebar.
- เกียร์ 1: For climbing hills or starting from a stop.
- เกียร์ 2: For flat terrain and general cruising.
- เกียร์ 3: For higher speeds or downhill riding.
- It is recommended to shift gears while pedaling lightly or when stationary for smoother transitions.
5.3 Braking (V-Brakes)
- The bicycle features front and rear V-brakes, operated by levers on the handlebars.
- The right lever typically controls the rear brake, and the left lever controls the front brake.
- Apply both brakes simultaneously for controlled stopping.
- Avoid sudden, hard braking with the front brake only, especially at high speeds, as this can cause loss of control.
