>>2013781take a shower before going out and wear a light shirt, you might sweat but probably wont smell.
if you have a backpack put it on a rack instead, let the bike carry the weight.
i also dont need to be careful to not sweat because i work a mix of open air and office so noone cares because here is hot most of the year.
my commute its 2km by bike + 30km by bus (company pays)
bike is picrel
