Perception is everything. Fashion and technology can be programmed.
The innovations I listed are not spectacular changes to the basic
bicycle design. They provide the necessary "product differentiation"
that allows confused buyers and slightly less confused reviewers
declare this or that bicycle to be in some way superior.
I forgot to mention one major change, that is probably the most
important on the list. The angled top tube. In the distant past, the
top tube was always horizontal (on mens bicycles). With full size
wheels, this limited the minimum size of the frame because when the
top tube met the down tube, there's very little room left for the head
tube. By angling the top tube, and thus compromising some frame
strength, a shorter wheelbase could be built that still allowed using
full size wheels for short or young riders. Of course, like any good
idea, one the designer was given the freedom to modify the traditional
frame geometry, it immediately morphed into a ridiculous extreme with
all manner of bizarre structural pretzels. Many were in places where
it made little sense, but did make the frame look different (or cool)
which was the real purpose. Still, I believe it's a major innovation.

Yeah, that's a problem. Like electronics, it would be nice to be able
to design to a specific lifetime, and then select components and
design parameters that would produce a similar predicted lifetime.
Anything that accidentally lasts longer than the predicted lifetime,
would be subsequently cost reduced to the desired level of
un-reliability.
Unfortunately, bicycles can't be designed like that. The problem is
that commodity machines have perhaps a 4x to 10x safety margin on most
components. You would not want a child's bicycle to pop welds when
they hop their first curve, or ride down the skool steps. You would
also not want the ultralite racing machine to fall apart when it hits
a pothole. So, we have safety margins to allow the machine to handle
such peak loads and stresses. Unfortunately, that tends to increase
the ruggedness of the bicycle, which by implication, increases its
useful life.
I could probably do something about the excessive lifetime by using an
automotive trick. People do not purchase a new car because of
mechanical problems or component failures. These are considered
normal, at least on American built vehicles. The GUM (great unwashed
masses) buy new cards because the car eventually starts to look like a
rolling junk pile. The upholstery becomes shredded, the dashboard
vinyl starts to crack, the paint fades, the chrome rots, the plastic
bumpers fall off due to weak fasteners, etc. Again, perception is
everything, and the perception of such a rolling junk pile is
sufficient to inspire buying a replacement[1].

I also have something like that. It's my 1970's Miyata 610, which I
really like, but rarely ride. Last summer, I decided to take it on a
spin. Instead, I spent a day fixing all thing that had deteriorated
and required replacement. I replaced everything made from rubber or
vinyl, re-greased everything, replaced the rusted chain, tossed the
moth eaten saddle, and replaced the crumbling wires to the lights. If
you dig out your 1930's antique, I would suspect that you'll have the
same problems.

True, but for a different reason. I have 3 doctors and 1 dentist, all
overweight. Somehow, their recommendations of getting more exercise
by cycling doesn't seem to hold much conviction.
What will inspire the purchase of a new bicycle is the cost of
resurrecting a new bicycle. My former ladyfriend decided to do her
good deed for the proverbial little olde lady and get her a bicycle
(because her son stole her bicycle and sold it for drug money). She
found a small bicycle for a few dollars at a garage sale, and had a
mechanic clean it up, add some necessary parts, and in general make it
rideable. When I saw the price tag, I was disgusted. She could have
gone to a department store and purchased a brand new equivalent
bicycle for only slightly more than what she paid to fix the old
bicycle.
So it will be with the aforementioned old bicycle owner. He'll get an
estimate for resurrecting his old bicycle, and with more than a little
encouragement from the LBS, probably buy a new machine.

Permit me to amend that slightly. "Wow, this old bicycle is painful
to ride. The aerodynamic posture is hurting my back. How much will
something that's more comfortable cost?"
In my case, the purchase of new technology is largely based on
borrowing a similar machine and riding for a few miles. Incidentally,
I'm looking at a new machine with a gear hub and drive belt, but I
need to get rid of a few of my other machines first.

I just hate it when that happens. Discussions are so much more

I like to classify them by the type of riding. Some have multiple
frame geometries in a single class. Off the top of my head:
- Casual rider (department store or mail order machine, comfort bike).
- Road racing (road bike)
- Mud and dirt (Cyclocross and Mtn bike)
- To/from skool, work, party, etc. (utility bikes)
- Touring (long wheelbase, some recumbents, Mixte)
- Travel Tourist (folding)
- Club events and century rides (almost anything that moves)
- Triathlon (road bike)
- Track racing and time trial (track bike, single gear)
- Stunt riding (BMX and Mtn bikes with suspensions)
- Downhill kamikaze (Mtn bike)
- Exercise machine (Fixie)
- Conglomerations (tandems, trailers, booze-cycle, utility)
Probably some more that I missed as well as borderline machines. I
tried to put them in order by number, starting with the most common.

Usage. I've noticed that for those with multiple machines, each one
has a very specific and different use from the others. In my case, I
have an office bicycle for doing quick errands, a touring bicycle for
long rides, and two strange machines on which I run experiments. I
also have a fast road bike, but it's too small for me now. Three of
these are generally considered mountain bikes, but the uses are very
different. Again, it's not the style. It's the use.

Very true, but it's those accessories, bolt-ons, options, and gadgets
that differentiate various bicycles in the mind of the buyer. I've
watched buyers in a LBS and found that nobody really looks at the
major parts of the bicycle. Instead, they look at the gizmos and
gadgets that they can play with while riding (just like any toy).

Does a canvas shopping bag with shoulder and waist straps qualify?
It's somewhat like a back pack but without all the pockets and
compartments. It's really ugly, but it's the only design that will
hold both a laptop and some groceries at the same time.
You're just proving my point. Accessories are VERY important and can
easily be what makes or breaks the sale. In your case, it's unlikely
that you're going to be adjusting the frame geometry with a saw and
brazing torch, but accessories are well within everyones capabilities.
I think I'm on my 4th set of brake levers and 3rd set of folding
pedals.

Welcome to the wonderful world of marketing. Let's start a campaign
of designed obsolescence in bicycle design. Every few years we add
fins, wide tires, narrow tires, aerodynamic accouterments,
instrumentation, air brakes, parachutes, seat belts, XM radio, water
filled saddles, garish colors, and whatever else is needed to make
existing bicycle owner think that they're riding machine is obsolete
or out of fashion. In other words, make riders unhappy with what they
own. This is not so far fetched as it seems. In the hybrid
automobile market, manufacturers were having a difficult time
convincing customers to pay the high prices and accept the marginal
cost savings. Instead, they emphasized that the customer knows all
this but is making a statement for ecology, conservation, and saving
the environment. That could easily be transplanted to cycling as the
crusade to improve national fitness, save gasoline, reduce air
pollution, fight global warming, etc. Perhaps we should attach
automobile style smog stickers to bicycles that offer ratings in
"pounds of CO2 saved per mile" to make the buyers feel better about
the purchase.
[1] Incidentally, that's a trick that I also use in my computah
repairs. I always spend the time cleaning the machine, even if I
can't fix it. The customer will not believe that it is fixed unless
it looks almost like new.
