Its being appropriately dressed, in the swimming baths or in the sea, wearing just your swimming trunks is being correctly dressed, out on the street without underwear is wrong, I suspect if I did it I would feel a bit sleazy
you're not 'out on the street', you plum - you're riding your bike...
No-one is going to see your ding-a-ling.
On the subject of flashing, I've ditched shorts in the past because, after a lot of wear, they were verging on the indecent, even with underwear
