For example, S3 in Qiao Shan, BC4730 and BC4650 spinning bikes in Wilson Tsui are all belt drives, which are very quiet and stable; Wilson Tsui's BC4330 is chain driven and has a loud sound. As for which quality is good, it depends on the grade and various configurations of this machine.
At present, the magnetically controlled cars on the market, including imported brands such as Qiao Shan and IPAS, as well as domestic brands such as Wilson Tsui and Recreation Home, all use belts and are very quiet. Unless there is something wrong with the quality of the machine, there will be abnormal noise.
As for the choice of spinning bike or magnetic control car, it depends on the individual's detailed sports needs.
