Looks like a nice bike. I also like the specs of the Marin "Lucas Valley" which is a slight downgrade in components for $400 less. Though they are listed as flat bar road bikes, both are geared a bit lower than a true road bike, have larger tires, and have tube angles more like a mountain/hybrid bike. Just something to consider.
If you don't mind me asking, why do you need a flat bar? A drop bar provides so many more hand positions.
