Hi Joe!
What some people do is offer their bikes here first, then if no interest, pursue a wider audience via eBay.
An alternative is to list the bike on eBay with a link-back to the Forum.
Both have proven to be successful strategies.
Set your starting/reserve price to your acceptable minimum if going the eBay route. A few have started very low and found themselves giving their bike away.
Best of luck on your upcoming sale.
Dan.
