The resistance of the magnetically controlled exercise bike becomes smaller.

The decrease of resistance of magnetically controlled exercise bike may be caused by degaussing. Please note that this is a gradual process, which may gradually decrease over time. In addition, this may also be due to other factors, such as the change of magnetic field around the current-carrying conductor, when the closed circuit moves in an uneven magnetic field, etc. In order to solve this problem, we can try to send it back to the manufacturer for repair.
