Since theyu2019re powered by wind resistance, air bikes tend to be louder than most other cardio machines. Some, however, are quieter than others.

Generally, air bikes produce a sound akin to white noise, though it can evoke the roar of a vacuum cleaner during sprints. So long as youu2019re biking at reasonable hours, the sound should be manageable for neighbors and roommates.
