I’ve got the belt drive one with the leather pad for resistance (SF-B1002) and haven’t had any issues. I’ve been impressed that it feels like an average spin bike you’d find at a gym (for $400!). Did you have the magnetic version?

This is the same bike I had. The drive belt eventually frayed/snapped. Sunny customer support was terrible and I got way more help trying to fix it on a Sunny owners Facebook group.
