4. Operating Instructions
4.1 Adjusting Resistance
The bike features a micro-resistance adjustment knob located on the main frame. Turn the knob clockwise to increase resistance and counter-clockwise to decrease it. This allows for precise control over your workout intensity, simulating various terrains from warm-up to intense climbs.

To engage the emergency brake, press the resistance knob down firmly. This will quickly stop the flywheel.
4.2 Using the LCD Display and Heart Rate Sensor
The integrated LCD display provides real-time feedback on your workout. It typically activates when you start pedaling or press a button.
