DETROIT:

Many bikes are posted daily, but 50 percent or more are children's/BMX bikes.

The rest are MTB's of every description, along with various cruiser and comfort bikes, and over-priced DKO-flipper bikes (many with the dirt still on them).

...Did I leave anything out?
Oh YEAH!
C&V road bikes!

Less than 2%.

Many days can elapse with nothing worthwhile, and then a few "reasonably" priced deals may pop up.

Actual flip prices are rare of late, but they still happen, and every once in a while - there is still that one killer deal.
