That's pretty much an ideal commuter bike. "Road bike" means you don't have the mushy suspension or knobby tires of a mountain bike, so it won't be slow. "Flat bar" means you get a slightly more upright riding position, so it will be more comfortable and give you better traffic visibility.

Also the component group looks solid, disc brakes are a plus for stopping power rain or shine, 32-spoke wheels should be robust enough for rough city roads.

Ride and enjoy!
