Absolutely magnetic control. It uses the resistance generated between magnets to control the resistance. There is no noise. Riding is smooth and not astringent, and the ribbon has a long service life. It's just a belt that connects the resistance plate to produce friction. This kind of riding experience is poor and its service life is short. Generally go to the online mall to see the price. Okay, it's all magnetic control. Where is the cheapest exercise bike with belt at present? The same ribbon version 1560 yuan. A model of the magnetic version of 350 yuan or so, the price is basically more than double. You can imagine how big the gap is. If you have a physical store to experience it yourself, you will know.
