Adding all that together, along with fairly flat terrain, equals perfect commuting. People forget just how far north cities like Copenhagen are; it's about the same latitude as the sourthern tip of Alaska. Most of Germany is farther north than the northern tip of Minnesota.
US cities like Philadephia, Pittsburgh, Chicago are at the same Latitude as Barcelona Spain, Naples Italy and Istanbul, Turkey. Kansas City and St. Louis are at the same latitude as Athens, Greece. Houston and New Orleans are the same latitude as Cairo, Egypt.
Europe is much milder on the whole even though it's more north. In addition, the average cycle commuter tends to be in better shape indicating that they'd sweat less. Also, I've never worked in a building with A/C, so I think we're more adjusted to slightly more sweaty people.
