I have several concerns when commuting, though safety is rather low on that list. My ride is rather longish, and at hours when no help is readily available, and even if it was - would be hard to reach me. The bicycle trail I ride (West Orange Trail - between Clarcona-Ocoee Road and Old Downtown Winter Garden has many parts with little to no road access points. I'm more concerned about breakdowns, such as a mechanical failure or flat (currently have no spare tubes, and changing a tire in the pitch black would be trying at best). I have sections of my ride that are rather nice, but the late hour usually means that they are very desolate.

I was pretty sure that I knew what you were thinking. ;)

To me unless the rider has some pretty specific needs there are multiple bikes suited for the purpose of basic transportation. Different styles of bikes have different tradeoffs and I would guess that no single type is going to please everyone, - even when it comes to comfort.

Some people would probably prefer that upright posture seen on Dutch bikes even for longer distances, but lots of people wouldn't. My evidence? Observe how people actually sit when there is no back support available. Folks may sit upright for awhile, but most will shift around quite a bit and spend a lot of time leaning forward using their arms and elbows for support.

Many recommendations for proper posture at a desk IS to sit up straight but that is with both back and arms supported.

As for the other characteristics of Dutch bikes, some will be highly desirable while others may count against it. Who wants to lug something like that up a flight a stairs or lift it on to the rack in front of bus? To some people that will make a Dutch bike very inconvenient.

Lastly there is personal preference and style. The most comfortable and cushy ride isn't always the most desirable trait for everyone or what's going to get them to ride.

I'm just curious. What is it about riding upright that makes one sweat less? That seems counter-intuitive. An upright posture makes for poor aerodynamics. That means you're either working harder to go the same speed or you're moving slower for the same level of effort, - which means reduced air flow around your body. However, I doubt it makes much difference when we're talking about hybrids or english bikes vs dutch bikes.

I clarified it only because I also thought you could think I was referring to all of the folks who have bikes in their garage with flat tires, derailleurs extremely out of whack, or other problems. I agree with most or all of what you said BTW. However, sitting in bleachers I may look much like the folks in your photo yet I'm comfortable riding all day on an upright.

Leaning forward creates skin folds which cannot naturally cool as exposed skin can. This causes a bit of extra heat throughout your body but also within the folds you overheat quite a bit. Also, when you sit upright you have greater 'wind exposure' vs being aerodynamic so upright may cool you better from this aspect as well.

Personally, I tend to also ride a bit harder on a road or hybrid than on a Dutchie.
