Eaten an entire bicycle?

Advertised a well-used bike saddle on onlyfans?

Written a bicycle purity test?

You're right. As I said, it was originally an article I wrote for our
club newsletter, just hoping to generate some interesting conversation.
Since few club members are technically trained and into mechanical work
except for the simplest maintenance, I avoided tech stuff.

For example (in disorganized order):
>
> Have you ever:
> - Torn a bicycle down to components and re-assembled it?

Yes, to add braze-ons and repaint. I didn't disassemble the spoked
wheels, of course. I've built other bikes from bits, including building
the wheels.

> - Replaced drive train components?

Sure.

> - Measured bicycle rolling resistance?

Only roughly, comparing various bikes and tires by noting max speed down
a gradual slope.

> - Measured front and rear wheel ground loading (weight distribution)?

Yes. That was part of an in-class exercise for my students, to have them
calculate maximum deceleration without pitchover. The tricky part for
them was calculating the height of the bike+rider center of gravity -
that is, the Y coordinate as well as X coordinate of the C.O.G. Care to
guess how?

> - Built and trued a bicycle wheel from parts?

Yes, many.

> - Welded a frame or fork?

Brazed on some fittings. Never welded on a frame. Never built a complete
frame from scratch. (I think John has.)

> - Analyzed bicycle or ride performance using GPS data?

Nope. I don't use GPS much on bikes.

> - Measured rubber hardness with a durometer?

Yes, but never connected with bicycling.

> - Read technical books on bicycle design?
> [later: I was thinking something more like:
<https://www.alibris.com/Bicycling-Science-Third-Edition-David-Gordon-Wilson/book/47815854>
<https://www.alibris.com/High-Tech-Cycling-2nd-Edition-Edmund-R-Burke-PhD/book/28070686>
]

Yes, three editions of the first one, which are on my shelf. Yes to the
second. Also, _DeLong's Guide_, _Bicycling Technology_ by Van der Plas,
_Bicycles and Tricycles_ by Sharp (~1890), _The Dancing Chain_ by Berto
and many others.

> - Inspected a CF frame for defects using ultrasound?

Nope. I greatly prefer metal.

> - Experimented with various bicycle lights?

Dozens, in many ways. For a few years, my commuter had two dyno
headlights plus a taillight for experiments and comparisons. One switch
turned the taillight on or off. Another switch selected headlight A,
headlight B, or both A+B. I modified quite a few headlights and built a
couple from scratch.

> - Verified published performance tests?

Not sure what you mean. Probably no, except for roughly verifying some
aero effects.

I think you might mean the z-axis (up - down) instead of the y-axis
(left - right). x-axis is (forward - back):
<https://en.wikipedia.org/wiki/Axes_conventions>

Put bicycle and rider on a seesaw. Move the fulcrum along the x-axis
until everything balances. That's the center of gravity along the
x-axis.

Unless the bicycle and rider are asymmetrical along the y-axis, the
center of gravity would be centered along the length of the frame. If
you want to measure it accurately, rotate the fulcrum 90 degrees and
move along the y-axis until it balances.

Have the rider and bicycle lay on their side in riding position on the
seesaw. Rotate the fulcrum 90 degrees from the normal seesaw
position. Move the fulcrum around until it balances. That's the
z-axis center of gravity.

z-axis could also be done with a hammock. Place bicycle and rider on
the hammock in a riding position. Initially, they're likely to flip
the hammock over and fall on the ground. Move the ropes at the ends
of the hammock toward each other until there's no tendency for the
hammock to rotate and dump the rider and bicycle on the ground. That's
the center of balance in the z-axis.

I guess the z-axis could be done with a platform, but a hammock is
more fun.

It's similar to weight and balance calculations in airplanes. The
measurement is done with jack stands at jack points for large aircraft
and load cells on level ground under the wheels of small aircraft.

All this makes the highly unlikely assumption that the rider will
remain in the same position/place throughout the braking event.

The unanswered question is "why?"

Nonsense like this is a good reason to question the value of some
classroom instruction. IOW, if the "instructor" can't even produce a
credible problem to solve, toss him/her out and find one who can.
Reminds me of the nonsense presented in grade school geometry
involving the height of a flagpole instead of a real life situation
such as designing and building a stairway.

Since the problem is two dimensional, we had no need of a third or Z
axis. In two dimensional Mechanics problems, axes are always marked X
and Y.

What we actually did was measure front and rear weight distribution on
level, then raise the front wheel a measured amount (I forget how much)
and record the changes in weight distribution. Once we had the data from
those measurements, it was a statics (mostly trig) problem to locate the
height of the center of gravity, or center of mass. This was relevant
for calculating maximum possible deceleration.

This was one of the few times I gave bicycle-related problems. The class
was unusually small and all the students were very competent, so I felt
fine about taking time to have some fun.

While I no longer remember the order of the problems, I had the class
take detailed measurements of a brake lever I donated. They then
calculated the estimated bending strength of the lever (we had to guess
at the alloy), which was surprisingly small. They calculated the brake
cable tension related to that strength, the force the brakes delivered
to the rim using that cable tension, and the deceleraton of the bike.

The COG height was used to prove that the surprisingly weak lever was
fine in practice because pitchover limits practical braking
deceleration. And BTW, the one football player in class was able to
crush the brake lever, which roughly verifyied our calculations. The
lever doesn't need to withstand the strongest human grip because the
system has other limitations.

You're welcome, but what *are* a "rock dodge" and a "tweed ride"?

A rock dodge is the act of whipping your front wheel quickly around an
obstacle like a rock, chunk of glass or small pothole. It keeps your
more vulnerable front wheel clear of the hazard even if you back wheel
hits it. See https://cyclingsavvy.org/2022/10/emergency-maneuvers/
or

A Tweed Ride is a goofy sort of costume party on wheels, a dress-up bike
ride to reenact the early 1900s in Britain. Somewhat formal Edwardian
costumes are the bee's knees, and ideally, bikes should be appropriate
for the era. (I do own one, in storage, that I think would qualify.)

I've never seen a Tweed Ride, let alone ridden one, but it would be fun
to watch.

The closest I came was once when we were riding in France, and we were
passed by an antique car club of some kind. About a dozen cars from
around the 1920s passed us, and the drivers and passengers were in
period clothing.

Ah, okay. I was envisioning trying to avoid a flung projectile from an irate
pedestrian or the like.

The dodges I most frequently do around here is on what (I consider)
sub-standard width lanes to go around storm drain grates.
The City of Capitola has a passive-aggressive hatred of bicycles for some
reason. They certainly pay lip service to bikes and all, but the major
roads--41st Avenue and around the local mall for example--are anything but
bike friendly.
I go there fairly often via cycle to shop for groceries.

That sounds fun. My college pal, Robert, who owns the 1888 Columbia I got
to ride often dons period clothing when he rides it.
He has gotten quite a bit of grief at times from well-meaning
ride-particpants who think he absolutely should and must, wear a helmet.

Robert thanks them and explains, why yes, I normally do wear a helmet, but
this is one of those times where I am willing to take a risk for sake of
period appearance etc.
This *usually* mollifies his interrogator, but one time a girl just would
not quit harranguing him. She eventually got tired and went off looking for
something to cool her tonsils, I imagine.

I loved to bask in the reflected glory of being the friend of the guy
getting all the attention for his bike.

A common exchange:
Man: "Is that what the original would look like?"
Robert: "It *is* an original."
Cue long pause...it took an really long time for the fact to sink in that
they were actually looking at and touching a rideable bike from 1888.

I don't recall a lot of picture taking, this was mostly pre
tool-of-the-devil (cell phones).

My Cannondale is 80's vintage, so not that old.

I've had two friends who owned Ordinaries or "High Wheelers" and let me
ride them. It's a really nice experience! The tall bike is amazingly
easy to balance at low speeds, and the ride is very smooth, at least on
reasonably smooth roads. But it's nowhere as easy to pedal as a modern
bike.

Getting mounted is only slightly tricky. Dismounting is slightly
trickier, involving reaching back for the "step" before sliding off the
seat. But I've seen one of my friends dismount by swinging both legs
(one at a time) above the handlebars, then hitting the spoon brake. The
bike stopped and he landed on his feet in front of it, still holding the
handlebars. I've never tried that.

How about:
- Get drunk at church on Sunday morning and take your roadbike down the gnarly trail?

Good one!

I've taken my roadbike down some moderately gnarly trails. But never drunk.

And I've never gotten drunk at a church ... well, unless you count
wedding receptions in parish halls in days of yore.

Have you ever taken a rest break and had some nosey potatohead stop
beside you and try to start a conversation?
