Get a motorized bike, scooter, or light motorcycle if you don't want to exercise. I've thought about getting a ninja 250 or a scooter, (did just take the MSF safety course) but I'd rather be out of traffic flow at slower speeds, getting exercise. I may yet get a motorcycle at some point. Here are are op.

You can get used pre 2008 ninja 250 bikes for as much as an entry level road bike, and plenty of decent more powerful motorcycles for the cost of a mid to high end road bike.
