Whats the point of manufacturers touting their indoor trainers as durable or long-lasting when they rarely provide concrete data to back up these claims. Every trainer on the market seems to have some variation of a heavy-duty or industrial-grade construction, yet were still seeing reports of broken flywheels, malfunctioning resistance units, and faulty electronics after only a few hundred hours of use. How are we supposed to make informed decisions about which trainer to purchase when the manufacturers themselves are so evasive about the actual lifespan of their products. Can anyone provide some real-world data on the mean time to failure for different indoor trainers, or is that information just too inconvenient for the manufacturers to share.
