What is the difference between magnetic and friction resistance?

When it comes to resistance systems in stationary bikes, there are typically two main types:

• Magnetic
• Friction

The magnetic resistance system uses magnets to create resistance as you pedal. The resistance level is adjusted by moving the magnets closer to or farther away from the flywheel. One of the big advantages of magnetic resistance is its quiet operation.

The friction resistance relies on pads or brake pads that press against the flywheel to create resistance. Adjusting the resistance typically involves tightening or loosening these pads. Friction resistance can provide a more road-like feel since the resistance increases as you pedal harder, mimicking the experience of riding outdoors. However, it can be a bit noisier than magnetic resistance.
