Human stink comes from poor hygiene, not physocial activity. I shower, shave, deoderize in the morning before I bike just as if I were driving. And I put on clean bike clothes just as I would put on clean street clothes if I were driving.
I ride 14 miles to work. Change. Work. Change back. Ride home. I don't use wipes, febreeze, lysol or anything else on myself at work. I may towel off if I'm really sweaty, but usually not.
At the end of the day, I never smell any worse than if I had driven my car.
