I took part in the discussion mentioned too and I maintain that the average person doesn't have to sweat commuting.

- It might require a little training, but in Copenhagen the speed of the green wave (synchronized traffic lights) is 20 km/h or 12 mp/h and that is aimed at commuters in their regular clothes.
- It requires attention, if you start sweating you're too late with slowing down. It possible not to heat up too much while averiging 12 mp/h, it not possible to cool down averiging 12 mp/h, or 11, or 10.
- Adjust your clothes to manage body heat while riding, and you can dress for the destination but it's okay to be a bit cold the first 2 minutes of your commute. You don't need to dress for the cold like you're going to sit still in it if you'r going to ride in it.
- Keep momentum, don't do bursts, don't use your opper body and keep a straight line.

In my experience if you're fit you sweat less, if you sweat a lot at other exercise and rehydrate properly your sweat won't be a smelly. Fresh sweat does smell but not bad, old sweat smells bad, and old deoderant that has been 'worked' smells even worse.
