If you're not used to intense exercise, your body will just make the stinky kind. After a while your body learns there's no need for that, it's not a life or death situation, it's normal, and just makes the wet kind, nonstinky, which dries pretty quick, what little you'll get, once you get to work.
BO has nothing to do with pheromones. All sweat is odorless. What causes BO is bacteria that live on your skin consuming oil from certain oil producing sweat glands (not as numerous as water producing sweat glands). Actually it's the bacteria's waste products. Assuming you were clean before your ride, you won't stink right away after a ride. It takes time for the bacteria to do their nasty work. If you shower before your ride and use anti-bacterial soap, then use an anti-perspirant + deodorant, you can head off BO. The oil producing sweat glands are most predominant in areas where you have hair. So you can take a washcloth or a sponge, and give yourself a sponge bath in those areas after your ride, and greatly reduce the problem also.
