The biggest problem I can see is that you will never be able to get an ideal photo of the bike since you can't match the crank arm angle to that of the seat tube!

I think it's ridiculous.

This came to mind for me...

What... no Cygnet ?

:D

There are only a handful of these on the planet unless you want an original... which will cost many times what the reproduction costs... which is still a fair bit of change due to the extensive amount of custom work required to build this bicycle.

It is actually easier to build a conventional tandem.

The frame has to be hand formed and it took a lot of prototypes to determine the right type of steel and the bottom bracket and cranks also have to be custom made.

One can see how the diamond frame became dominant... it is fairly easy to fabricate and is very strong while the Pedersen also requires an intense amount of work (almost 60 brazed joints).

didn't someone say that to Orville and Wilbur? is it suposed to be a shock absorbing thing?

And I say let the people judge. Crank out a few thousand and see where they go.

(I dont care for the looks)

Larger cantilevers, while not light, do offer a smooth ride and (in my opinion) beautiful lines. You'd be surprised how often people look past the old, chipped paint and mention how much they like the looks of this bike:

The frame design of the roundtail bike in question is based on principles that have been applied much more tastefully in the past.

Interesting. I'm waiting for the next triangular wheels. I'm sure they'll be advertised as giving a greatly improved ride.

A precursor:

I do like THAT bike, uprighter. It deserves a new chain. ;)

Colonel, I love Mr. Horse. My wife says I talk and chew like him.

I saw vertically stiff mentioned in the copy but what about the lateral stiffness huh? All the best bikes these seem to be vertically stiff AND laterally compliant. I prefer my laterallness to be compliant thank you very much. Also this thing needs 650b wheels with 55mm tires.

What we really need, given the rise of disc brakes, are ovoid rear wheels to compensate for the dead spot in the pedal stroke.....

Oh wait... that would only work at 1:1 gearing...
And then there's biopace...


So, yeah, the more I look at that bike the more I ask myself, "Why?"

The reason you get compliments on that bike is because Schwinn gave it perfect proportions. Still an elegant design after all these years. Knockoffs are always just slightly off compared to the original.

Well, we have our answer:


Sponsorship
