Fixed Gear and Single Speed bikes generally do not make good commuter bikes unless your route is fairly flat and you don't have a lot of stuff to carry with you. bigShot Bikes bill themselves as being minimalist bikes, iow, they have no bells and whistles added. Oh, they will give you brakes if you order them and you can pick your color(s) and style of handlebar(bull horn or flat bar). They make no provisions for racks or water bottles, and you will need to carry a 15mm wrench with your flat kit as they do not provide quick release wheels. They say that they are minimalist bikes, but not, it seems, in the weight department. Their own website states that their bikes without accessories weigh between 23 and 25 pounds. Not that good for a bike that is not carrying around a 20 speed drivetrain and all of the other little things that most roadies like to carry.
If you want to be "cool", then by all means this is the bike for you. If you want to successfully get where you are going and get back again without killing yourself, a more conventional multi-speed bike would be in order. I do have to applaud bigShot for one thing, they make their own purpose built frames instead of ruining good vintage frames to make their fixie/ss bikes.
