I'm selling my bike DiamondBack Insight Performance Hybrid 2012 for $250 (original price was $450). It's in great condition, everything works well (I hardly ever used it since I never really learned how to bike!).
It's been parked for almost two years. Comes with a free $100 lightweight U lock (Abus Granit Futura 54/120 hb), front light, back light, basket, helmet, memory foam seat cover, bottle holder.
