The rated noise level of the smart trainer is measured at a moderate cadence under normal cycling conditions. The design of the smart trainer is relatively quiet, but it is normal for buzzing sounds and some vibrations to occur during cycling. The freehub body naturally produces a "click" sound when sliding. Please note that during deceleration or high-speed stepping, you may encounter additional noise and vibration. Warning: Do not attempt to disassemble your smart trainer to diagnose noise or vibration. Disassembling without support guidance may void your warranty.
Considering this, attention should be paid if any of the following sounds are heard:
