crankarms with spoked-wheel spider armature, made of thin spokes

The idea of having to true my chainrings periodically is more than I
can bear. I think I'll stick with "mags" and "discs".

Dear Chalo,

Are you sure?

I often read on RBT that once a wheel has been properly built, the
spokes never need to be touched again until the rims wear out, a stick
or the chain damages the spokes, or an airline employee attacks it in
transit.

A novel spider would be a way for you to stand out in the crowd in
Texas, instead of modestly blending in like a dwarf sasquatch refugee
on dull bikes like this:

Genius!

Now, how many other bike parts would be amenable to replacement with
spokes?

Downtube, for one,

Dear Ryan,

Well, in-tension down-tubes (and chainstays) were a bit thicker than
spokes . . .

But they were a common design in early frames.

Assuming a perfect vacuum and pavement asperities not exceeding (1.47
x 10^-3) x (diameter of wheel) RMS. Hmmm... since I ride in
conditions like that, my wheels must be coming out of true from time
to time for some other reason. Maybe my cats are trying their paws at
cycle maintenance?

If I used my preferred 48 spoke cross-five pattern, I might be the
toast of the local lowrider bicycle contingent. I wonder how well a
72 spoke radially laced version would hold up? Perhaps comparably to
the sassy, classy twisted sprocket: http://www.lowrider-depot.com/36830.jpg

Dear Ryan,

Turning just the downtube into a spring doesn't eliminate the dead
spot--they need to replace the chainstays, too!

And maybe add a little tension to the back of the seat:

interesting, but nowhere near as interesting as the shimano 10mm also
shown on that page. i'd like to see shimano revive that idea.

Well, there was a tri-bike that had a spoke for a down-tube, or maybe
a cable. don't remember the name of the frame.

more evidence of the abysmal engineering schools we have these days.
"engineers" that don't consider torsion in frame design? they probably
don't understand the difference between elasticity and plasticity either.

Slingshot made a mountain bike like that.

"Slingpower"? How appropriate.

Of course it does have a composite element, should be great, infinite
strength & rigidity. Fortunately it's also replaceable.

Interesting picture of John Howard's land speed record bicycle. I
recall seeing it at InterBike and noting that the gear was so high
that it could not be moved by pedaling. The bicycle had to be towed
up to a speed that the airfoil developed enough vortex to propel the
bicycle. The airfoil behind the racing car was so effective that he
had to use the brake to not hit the bumper bar that is visible in the
picture. The "throttle" was on Howard's handlebar so he wouldn't get
dropped by slight speed variation of the pace car.

If find such efforts mainly a show of derring-do.
