Delizy & Poiret: Keeping Riders En Suspens

It seems that the moment the first bicycle--however you define it--was created, someone was looking for a way to insulate the bike, and rider, from shock.  When you look the Draisienne's wooden seat and the iron wheels of subsequent machines, you can understand why someone wanted to make them more comfortable to ride.  And if you know anything about the conditions of roads at that time, it's not hard (pun intended) to see the need for a shock absorber to make bicycles (and bicycle-like contraptions) more stable.

If we define "suspension" as anything that insulates ("suspends") the bike or rider from shock, one could argue that pneumatic tires, invented by John Boyd Dunlop in 1888, were the first form of suspension for two-wheelers.  In fact, one could even say that when, a decade earlier, John Boultbee Brooks stretched a piece of leather between two rails, he was the first to achieve the goals of every suspension system created since.

So, really, it's not such a surprise to see a suspension bicycle gracing an advertising poster early in the first worldwide Bike Boom:

I could find very little information about Delizy and Poiret.   All of it was in French--which, fortunately, I can read.

 Apparently, D et P started making bikes around 1890 and weren't in production for very long:  I saw an announcement for the dissolution of the company dated 17 July 1892.  Their bikes were made and sold at 22,rue Duret in Paris.  This factory and showroom stood  just off the Avenue de la Grande Armee, which streams into Place Charles de Gaulle Etoile (the location of the Arc de Triomphe) and was, until 15 or so years ago, lined with the boutiques of the major French (and a few foreign) bike makers.

All right.  You know that I find stuff like this interesting.  So do you:  Otherwise, why would you have read this post?  But you also know that writing this post was just an excuse to put another cool vintage bike ad on this blog!

Suspending Disbelief

I started mountain biking right around the time suspension front forks were becoming a standard feature of serious off-road machines.  Back then, it seemed that designs were changing every week, and that if you bought a Rock Shox Mag 20, or a Marzocchi or Manitou telescoping fork, a year later you could get something lighter, more durable and with more travel--whether from those brands or one of the new marquees that seemed to appear every month.

Suspension (telescoping) fork advert, September 1992

  

By the time I stopped mountain biking and sold my Bontrager Race Lite, in 2001, new suspension forks bore little resemblance to the ones I saw and rode nearly a decade earlier.  Moreover, bikes with suspension in the rear of the frame had become commonplace, with designs that changed as rapidly as fork designs had been changing.

Even with all of that design evolution, there were some ideas that, apparently, no one ever considered.  Can you imagine how mountain bikes--and mountain biking--would be different if the first suspension system looked something like this?:

To be honest, I'm not sure I'd want to ride such a bike, especially on rocky ground.  I'd guess that even when I was skinnier and more flexible than I am now, I wouldn't have been able to keep my feet on the pedals for very long.


 



 


Then again, maybe the bike isn't made for spinners or sprinters.  It's called a "Flying Bike" because, I believe, it's made for riders to pedal for a few rotations before lifting their feet and "flying".  But I have to wonder whether it would feel like flying if the bike is bouncing through potholes and over rocks.

If you think the "flying bike" is weird, check this out:

 Can you imagine what mountain bikes would be like today if that had become the paradigm for suspension?

Starstruck? No, A Moonshock!

Bicycle suspension--at least in forms we would recognize today--first started to appear, mainly on mountain bikes, a bit more than a quarter-century ago.

Those early attempts to make bikes more stable as their riders bounced them over rocks and rumbled along singletrack consisted of hinged handlebar stems with springs in them, seatposts that were like pogo sticks and "telescoping" forks.  That latter system--first popularized by Rock Shox--would become one of the standard ways of suspending bikes.  The other--suspension built into the rear of the frame--would come a few years later.

Most riders at the time thought all of those attempts to absorb shock were new innovations.  Of course, they weren't old enough to have been reading American Bicycling (the forerunner of Bicycling) when it featured Dan Henry's homemade suspension system on his French constructeur bike.  And, at the time, even I (a professor who's supposed to know everything, ha-ha) didn't realize that bicycles have been built with suspension for almost as long as bicycles have been built.  What is the pneumatic tire--one of the most important technological innovations of all time--but one of the first, and one of the most enduring, forms of suspension?

Even with such knowledge, I was a little surprised to come across this 1975 Redline Moonshock BMX bike:

Only five or six bikes like this one were ever made, according to the Classic Cycles website. In the then-nascent sport of BMX racing, bikes were designed to consciously emulate their motorized counterparts.  That makes sense when you realize that, at the time, most BMXers were pubescent boys who, like lots of other kids, pretended they were on motorcycles or in racing cars as they plowed along paths and jumped ramps and mounds.  

Note the year:  1975.  Schwinn had ended production of their "Krate" series, which probably best exemplified "muscle" bikes that echoed the "muscle" cars of that era.  If those bikes weren't at least partially responsible for the birth of BMX, it's still not merely a coincidence that kids started "revving" bikes with slick fat tires and "banana" seats during that time.  

It was also during that time--at least, according to the accounts I've read and heard--that Tom Ritchey, Gary Fisher, Joe Breeze and their friends were bombing down Northern California fire trails in Schwinn baloon-tired bikes made before they were born. 

Why do I mention that?  Well, the first problem that most of those proto-mountain bikers discovered had to do with one of Newton's laws--best expressed (at least for mathematically-challenged people like me) by a Blood Sweat and Tears lyric.  What goes up must come down--but what comes down can't always be brought back up, especially if it weighs 60 pounds and has only one gear.  So, according to lore, in 1975 (or thereabouts), Gary Fisher outfitted one of those balloon-tired bombers with derailleurs and multiple gears.

Apparently, some BMX bike designers thought absorbing shock to make the bike steadier was a greater priority.  Mountain bike designers wouldn't come to the same conclusion for another decade and a half.

Not surprisingly, the Moonshock BMX bike shared a couple of unfortunate traits with early suspended mountain bikes.  They were slow, basically for the same reasons.  For one thing, they were heavy--although, in fairness, the Moonshock had the greater weight penalty because of its tanklike gussetted steel frame, wide rims and tires.  (By the time mountain bike suspension was developed, relatively light frames, tires and rims were available.)  But, more important, the springiness of both kinds of bikes absorbed much of their riders' energies.  Thus, the few kids who rode the Mongoose, much like mountain bikers nearly a generation later, found ways to lock out their suspension systems.  That left them riding almost-rigid bikes that were several pounds heavier than their non-suspended counterparts.

It seems that the idea of suspension on mountain bikes died with the production of the Moonshock, or not long after.  Apparently, BMX riders felt that it was more important for their bikes to withstand the pounding they would take.  And, because BMX frames and wheels are smaller than their mountain or road counterparts, it's possible to use relatively thick gauges of steel, with reinforcements, and end up with a bike that isn't terribly heavy.

On the other hand, it's all but impossible to buy a new mountain bike (or any made in the past fifteen years or so) that doesn't have suspension in the front fork, rear triangle or both.  Best of all, many new systems seem to have some way of locking them out--or regulating the firmess or softness of the ride--built into them.  And a typical suspension fork of today is a good deal lighter than the Rock Shox Judy fork--top-of-the-line in its time--I rode on my old Bontrager Race Lite.

His Spirit of Innovation Wasn't Suspended

The other day, I wrote about some bicycle suspension systems that were patented nearly a century before Rock Shox or Girvin Flex Stems came bouncing down the trails.

It's not as if the idea of cushioning the ride and rider died with the fin de siecle Bike Boom.  Indeed, some of you rode balloon-tired Schwinn, Columbia, J.C. Higgins or other bikes with a big spring in front of your handlebars.  That spring was attached to a bars that were, in turn, attached to the front fork.  How much that actually absorbed shock, I don't know.  I have long thought that they--like the "banana" seat struts attached to shock absorbers on bikes like the Schwinn "Krates"--were really intended to enable kids' fantasies of riding a "chopper" on the flats of Daytona.

Around the time that boys (and, on occasion, girls) were tearing up and down driveways and cul-de-sacs, one of the few American adults riding at the time was thinking about real, functional suspension for bicycles.  Having been one of the first commercial pilots (for American Airlines), he no doubt saw the value in keeping his bike stable and upright (the real purpose for suspension on cars and motorcycles) in turbulent conditions.

If you've on any kind of organized bike ride for, say, the past half-century, you have heard his name.  More precisely, you have followed his directions.



Yes, there was a real, live Dan Henry behind the "Dan Henry arrows".  While he is best remembered for his system of road symbols, his most interesting contributions to cycling may well be in the ways he made his bikes more comfortable and stable.  



I remember reading about Dan Henry's bicycle in an issue of American Cycling, the magazine that became Bicycling!  As I recall, the bike was a Rene Herse or Alex Singer--or that of some other prestigious French builder.  He made the mechanisms himself from springs and bar stock he obtained in auto-repair shops.  Again, if memory serves, he said that this system allowed him to ride the lightest tubuar tires and rims under nearly all conditions without getting flats or dinging his rims.

(Interestingly, he would later convince Clement to make tubular tires with butyl tubes, which are more durable and retain air longer than the latex tubes commonly found in high-quality tubulars.)

Another part of his "suspension system", if you will, was something he made himself--from a pair of handlebars, a tandem "stoker" stem and some canvas webbing.  

It seems that every decade or so, someone re-invents this saddle.  When I first became a dedicated cyclist (around the time I found that copy of American Bicyclist in the local library), a similar saddle called the "Bummer" was advertised in Bicycling!  I think one of the magazine's editors test-rode it, probably unaware of his perch's provenance.  

Perhaps it's not surprising to know that Dan Henry was also one of the early proponents of recumbent bicycles, and that he designed and rode such a machine.  I guess he was one of the first cyclists to see that high performance and all-day comfort needn't be mutually exclusive--and, as an engineer and pilot, was one of the first modern cyclists to have the background and skills to realize such a vision.

He died nearly four years ago, just short of 99 years old, riding almost to the end.  I wonder what he thought of some of the suspension designs--especially for downhill bikes--that have come along.

They Didn't Come As A Shock Then...

Writing recently about "path racers" and the mountain bike experiences of my youth got me to thinking of just what it means to be a "mountain" or "path" rider--and what makes bikes suitable for those kinds of riding.

I also got to thinking about how and when those kinds of riding came to be seen as distinctive from other kinds of riding, and how the terms to describe them came to be.

It seems to me that those kinds of cycling and bikes--as well as cyclo-cross and bicycle motocross (BMX) evolved as specialties within cycling because of paved roads. 

Think about it:  In the early days of cycling, there were few paved roads.  And the few paved roads had gravel, cobblestone or granite sett (a.k.a. Belgian Block) surfaces. Thus, most of the time, cyclists were riding under conditions that, today, we would equate with off-road or cyclo-cross--or what the Brits would call "rough stuff".

If you are a mountain or cyclo-cross rider, try to think of what your rides would be like with solid rubber tires--or no tires at all. In other words, think  of what it would be like to ride your favorite trail on bare wood or metal rims. That is, I believe, what normal riding conditions would have been like for most cyclists before the pneumatic tire was invented in the late 1880's.

And to think cyclists rode, not only without the cushioning of air-filled tires, but on front wheels that were almost as tall as the riders themselves!

So, really, it's not surprising that there were attempts to incorporate suspension into bicycles. 

This Blackledge bicycle, patented in 1890, uses a spring in the fork assembly to soften the blows from the rough roads of the day.  It seems that ever since the "safety" bicycle (two wheels of more or less equal size) was invented, attempts to incorporate suspension into bicycles began with the front fork.  For one thing, we feel road shock first at the front.  For another, shock to the front is more likely to upset our balance or momentum--and cause crashes-- than shock at the rear.

This Tillinghast bicycle, patented the following year, has another interesting front suspension system as well as a unique kickstand built into the pedals:

Still, attempts to soften the ride--and make the bike more stable on rough surfaces--weren't limited to tinkering with the front end.  Here is a drawing submitted by Fernand Clement for the suspension bike he patented in 1892:

Here is another early rear suspension system on a J.H. Mathews bicycle, patented in 1891:

Hmm...Wouldn't it be fun to envision Messrs. Blackledge, Tillinghast, Clement and Mathews showing up at Tamalpais a century after they created these bikes...but just before Rock Shox, Marzocchi, Manitou came along?

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.
