3.2 Adjusting Magnetic Resistance

The bike utilizes a magnetic resistance system, offering a wide range of adjustment from 0% (easy) to 100% (difficult) without maintenance or noise.

Suggested resistance levels for different workout intensities:

• 0-20%: Warm-up
• 20%-50%: Running/Cardio
• 50%-75%: Fat Burning
