But that seems to vary by type of bike. For road bikes, yeah, it's probably a decent enough starting point. In my experience, mountain bikes and hybrids tend to fetch less than that, though. Mountain bikes have evolved so much that the old ones aren't as desirable among mountain bike riders, and there just doesn't seem to be a strong secondary market for hybrids.
