Magnetically controlled exercise bike refers to the metal flywheel that produces resistance, and the magnet is close to it. By adjusting the distance between the magnet and the metal flywheel, the resistance can be adjusted to meet the requirements of different exercise intensities.

Internal magnetism and external magnetism talk about the magnetic control mode of flywheel.

The internal magnetic type has good stability and large resistance, and is suitable for long-term use with a large amount of exercise.

The drag coefficient of external magnetic type is smaller than that of external magnetic type, and the price of internal magnetic type is more expensive.
