Millions of folks outside the U.S. commute 1 to 2 miles. Perfect distance for riding. That said, I think you're over-complicating things. I assume you wouldn't drive a Formula One car to work and wear a fire suit, helmet, gloves, and driving boots? Why do that with a bike?

Get a good upright city bike, forget the helmet and other complicated gook, and enjoy riding and arriving refreshed and sweat free.
