You can list your trike on Bentrider but they have a new policy which requires you to become a paid member at a cost of $18 (just like this site) before you can post in the trike for sale section. New FOR SALE Policy Change - BentRider Online Forums The site was having too much trouble with sellers signing up and never again visiting the site plus the occasional scammer who joined, listed, and then scammed the buyer. You have a lot easier time selling the trike if you have been a long time member as that gets you more trust from a potential buyer. Remember that shipping anything as big as your trike is pretty expensive so a local sale often makes more sense. I bought my Greenspeed GTO from the listing on Bentrider and it was a great experience with both the seller and buyer happy.
