Is it a three-speed?
I have a (pre-MMM) Nirve cruiser, 3spd, which I've been using for transport. By the time I put a rack and foldable baskets on it, it weighs in at an excruciating 51 pounds. I, fortunately, work at home and live in a city, so it gets used for trips to the grocery, library, get kids from bus, etc. No commutes more than a mile and fairly flat. It's very smooth and you barely notice a load of groceries or books, LOL, but I can't imagine it being practical in any other situation to be honest. If the bike thing "sticks" like I'm hoping/planning, a lighter more practical bike will be in my future next summer. For now, my hair is on fire in a few spots, so I'm calling it a workout. ;)
