But hub gears are very reliable. An important issue here is weather.
If a bicycle is to be used for utility riding through winter snow,
sluch, salt and sand, a hub gear has major advantages over a
derailleur . My Raleigh Twenty, with its Sturmey 5-speed, gets me
through Boston winters without trouble. The one time last year I went
out and rode a derailleur-equipped bicycle during a December thaw,
road salt immobilized it the next time I tried to take it out! (I
should have rinsed it off with the garden hose -- lesson learned --
The resistance of derailleur gears increases greatly as cog sizes get
below 15, to the degree that internal gears can do better.
If you really want to depend on bicycling for transportation, you
need at least two bicycles. Then if one has a flat tire when you go
to take it out for your morning commute, the other stands ready The
second bicycle doesn't have to be anything fancy. In fact, best if
it isn't, like my Twenty, so it isn't theft bait when locked in an
urban area. See http://www.bikexprt.com/bicycle/mytwenty.htm

Some might say that hybrid systems have the advantages of both. On a
small-wheel bicycle, there is an additional advantage of an internal
or hybrid system: high gears without the need for a large chainwheel
or tiny sprocket. If the internal hub breaks down, generally you
still have at least one gear left, and the derailleur gears, so you
can still ride.

Well, that's a question of where and how the bicycle is to be used.
In most US urban areas, the 8-speed hub gear will be more than
adequate -- and replacement parts are available at any bicycle shop.
For the few steep hills, there's always the two-foot gear (step off
the bicycle and put one foot in front of the other, alternating
feet). For long-distance touring, the wider range and narrower steps
of derailleur gearing definitely are an advantage.

I second the recommendation for a large saddlebag. I have undertaken
weekend tours with no more baggage than that. A small, soft backpack
and rear rack also are useful for big grocery hauls and the like,
short of using the trailer.
