Hi, the same rules apply as the main marketplace. You need to set a price, and notify the staff to delete when your bike sells. You can also cross post one time per bike ad in here to the main marketplace subforum. This will give your bike a bit more exposure, and make your particular type of bike easier for your potential buyers to find. Thje Marketplace forums do require upgraded membership to post new threads, and you can upgrade at http://www.bikeforums.net/payments.php if you aren't already a Titanium Member of the older red star membership.
The for trade sticky thread is a courtesy to all membership levels, and there are to be no sales in there, and not even euphemisms for cash are acceptable. Sales are to be conducted in their own threads.
