My bike is a Nishiki Ambush I got at a rummage sale for $50. The frame and wheels are in good shape and it fits me well. The current crank is a Shimano 100GS with very worn chainrings. I plan to replace most of the parts over time. Once I've proved to myself that I'm going to stick with bike commuting, I will pursue buying a new and better bike. At that point this one will either be given to my son or used as my bad weather bike.
