They Have Been Done; They Will Be Done Again

Who made the first dual-suspension folding bike?

No, it wasn't Dahon.   Nor was it Montague.  Even Moulton's double-shock folder has antecedents.

We may not ever know for sure who made the very first bike of this type.  I did find out, though,that one was made 100 years ago by a company that's still making bikes.

Perhaps not surprisingly, it was developed for use in war.  Some of the earliest foldable or collapsible bikes were made for soldiers to carry on their backs. Some, like the one I'm about to mention, even had mounts for guns or rifles.

In 1915, all of the major European powers were embroiled in World War I.  Some of the best-known developments of that conflict are the machine gun (which is said to have inspired the ratcheting freewheel) and chemical weaponry.  It may also have spawned bicycles with suspension and some of the earliest foldable bikes.

Bianchi Dual-Suspension Folding Bike, 1915


A bike that could both bounce and fold was created for the Italian Army by--you guessed it--Bianchi.  The company claims that it was the first of its type.  That may well be true, but it's always difficult to say that anything was a "first" in cycling because so many designs simply disappeared without a trace only to be resurrected, sometimes by "inventors" who had no idea of their previous existence.

Still, I don't think folks at Bianchi are stretching the truth very much, if at all, when they say the dual-suspension folding bike they created for the Italian Army in 1915 was the first of its kind. There don't seem to be any records of bikes with dual suspension or folding bikes much before that date. Also, it's hard to imagine that the technology of the 19th Century--in bikes as well as manufacturing techniques--could have made suspended or folding bikes practical or widely available much before that date.

Whether or not it was the first bike of its kind, it's yet another example of how this passage from Ecclesiastes applies to the bicycle world:

What has been will be again,
what has been done will be done again;
there is nothing new under the sun.

Is The Old New? Or Is The New Old?

The book of Ecclesiastes tells us "there is nothing new under the sun".

That is no doubt true of the bicycle world, especially when it comes to "innovations".

I many not be very old. (At least, that's what I tell myself.) But when younger cyclists during the '80's treated newfangled aluminum frames with awe, as their counterparts would for titanium and carbon fiber frames a decade later, I could say "Been there, done that!"

When I was first becoming an active cyclist--and learning about different kinds of bikes--during the 1970's, frames were being made from all of those materials. Now, they weren't mass market:  In constant dollars, they were far more expensive, and even more exotic, than the ones made today.  !"

But aluminum frames were of the "screwed and glued" variety made by ALAN in Italy and, later, by Vitus in France.  Carbon fiber frames were similarly constructed:  the tubes were bolted and bonded into aluminum lugs.  And titanium frames, like those from Speedwell in England, were constructed in much the same manner as fillet-brazed steel frames.

Speedwell's construction, similar to those employed by rival titanium bike-maker Teledyne, were meticulous and sound.  However, the metal used was almost pure titanuium, which resulted in a bike that was neither stiff nor strudy.  No one realized that titanium had to be alloyed.

As for aluminum, everyone involved in building bikes knew enough not to use the metal in its pure form, mainly becuse aluminum alloy components had been in use for decades.  What they didn't realize, until the Klein bicycle was designed, was that they had to increase the diameter of the tubes to get anything like the stiffness of a good steel bike.

And there was even more to learn about using carbon fiber, and the molding technologies used now were two decades away.

Although I had witnessed earlier incarnations of those kinds of bikes during my youth, I didn't realize then that aluminum and titanium frames were built during the 1890's.  They weren't as widely-used as those of iron or steel--or even wood.  But it's still instructive to note that the technologies, in their rudimentary forms, existed then.

It was also interesting to find out--as I did, just recently--that two other "innovations" associated with the last quarter-century or so actually have as long a history as that of frames made from "exotic" materials.



Believe it or not, there were patents for suspension systems and aerodynamic bars in the 1880's and 1890's.  Any attempt to cushion the ride was bound to get a reception from somebody, as the high-wheelers and "boneshakers" of the time gave even harsher rides than modern time-trial bikes with the most extreme geometries.  Also, most roads of the time were unpaved.




But it seems that less effort was put into developing suspension systems once Dr. Dunlop invented the pneumatic tire.  It not only made bikes faster than they were before, it also gave a "floating on air" sensation, as at least one rider reported.  



As for aero bars:  Well, this pair was developed more for comfort:  It gave riders an extra hand position as well as a place to rest their arms.  A few riders have told me they rode aero bars for that reason alone, and it was one of the benefits of the "cowhorn" bars I rode on my old (Italian) Bianchi track bike.



There was another reason why aerodynamic bars were developed.  To be precise, there's a reason why two men in particular--brothers--came up with their version of them.





You might have guessed that the fraternal pair were Orville and Wilbur Wright.  Yes, they used their bars in attempts to measure air drag and wind resistance, two very important considerations in their development of their gossamer-winged wonder.

Springing Ahead

I try not to seem jaded, or to be condescending to the younger generation. ;-)  However, when you've spent enough time with anything--including bicycles and bicycling--you realize that there really is "nothing new under the sun."  To wit:

About twenty years ago, suspension was the great "new" development in bicycles.  But, as you can see, it had been done a century earlier.  It was revived at various times:  If you're a bit older than I am, you may have ridden a Schwinn or Columbia balloon-tired bike with a big spring on the front fork.

What will they re-discover next?
