Operating Instructions
1. 3-in-1 Multifunctional Design
The exercise bike offers three unique positions for varied workouts:
- Upright Competitive Position: For intense cardio workouts.
- Semi-Recumbent Position: For relaxed pedaling sessions.
- Standard Upright Position: For classic cycling.
Adjust the seat height and position to switch between these modes. The seat backrest can be folded for convenience.

This image demonstrates the 3-in-1 multifunctional design of the exercise bike, showing a user in a relaxed cycling position (semi-recumbent), another in a standard upright cycling position, and a third in an upright competitive position. This highlights the bike's versatility for various workout styles.
2. Adjusting Magnetic Resistance
The bike features 16 levels of magnetic resistance for a smooth and quiet workout. Turn the resistance knob located below the handlebars to increase or decrease the intensity:
- Turn clockwise to increase resistance (higher intensity).
- Turn counter-clockwise to decrease resistance (lower intensity).

This image illustrates the 16-level magnetic resistance control knob, allowing users to adjust workout intensity from low to high. Below are icons representing different workout types: leisure exercises, cardio workout, shaping exercise, and stabilizing muscle.
