My 6,7 year old ride up a bigger hill than that bridge to school. Are those other pictures supposed to be hills?
Of course you guys are all great cyclists, that's why you've won so many Tour De France lately. Oh, well nevermind about that one. You are overestimating the capabilities of your countrymen, and underestmating the ease of commutes over there. Of course you don't sweat, when I was there in July it only got into the middle 60sF. When I was there, most of the bikers I saw were barely making beyond walking speed. So let's see, country that is tiny, flat as a board, doesn't get hot, commuters riding as slowly as possible. I guess they don't sweat much.

You don't think some of these people who have commuted for years and years long distances are " used to cycle"? Get over yourself and your sense of superiority.
