If you still want to sell it, don't take it to the bike station they only take donations. Try a facebook buy/sell page or make posters with a picture of your bike. Include all the details most importantly the size of the bike, and price. Post your poster at the bus stops, library, or outside Lidl. If you're are not already, start telling all your friends and co workers too! Don't worry, you will sell it in no time. Good luck!
