Those look a little too relaxed for my taste but that doesn't mean they are bad for you. In that price range you might want to look at something like this:

It has relaxed handlebars, 3 speed internal gears and crmo steel frame.

disc brakes

being that you don't really know what you want you should at least test ride several bikes at a bike shop first to see the style that you like before considering a bikesdirect bike. Also keep in mind that there will be some assembly required with a bikesdirect bike
