It's weird. I was originally going to buy a second hand bike but couldn't even find one that wasn't a K-mart special that was going for $5 less than what they cost in K-mart. They sold 1.1 million bikes in Australia last year and second hand ones are as scarce as hen's teeth, even though most of those bikes will be sitting in garages and laundrys now.
The LBS won't even mention the words "second hand".
Weird situation.
