Dear Kinky,

I'm so used to seeing remote-steering and, er, unusual designs in old
patents that what really caught my eye was the dainty depiction of the
crank arm.

Judging by the inch-pitch teeth on the chain-ring, those are roughly
76 mm cranks.

Cheers,

Carl Fogel

Dear Marcin,

The question of "first" can be tricky.

First to be imagined?

I wouldn't be surprised if the bike in my link existed only in the
inventor's fevered imagination. That looks like a 75 mm crank, which
is not exactly practical.

First to be built, even as a commercial failure?

Here's the first safety bicycle, the 1879 Lawson:

Commercially, it was a flop.

So nephew John Starley's Rover gets the credit a few years later
(1884/5)as the first _successful_ safety bicycle:

Anyway, some early suspension . . .

Rear suspension, 1885 Whippet safety, same year as Rover:

A better view of the same model, ~1887, in Pryor Dodge's "Bicycle," a
Whippet spring-frame dwarf safety Linley & Biggs roadster with rear
suspension:

A Victor front-suspension patent application, filed in 1886--page down
because the fork is more complicated than the first drawing suggests:

Ad for the 1888 improved Victor front suspension, the famous
half-heart spring:

Full-suspension 1889 production bicycle, the Don No. 2 of 1889:

http://www.localhistory.scit.wlv.ac.uk/Museum/Transport/bicycles/Don.gif

"The Don Spring-Frame No.2 Dwarf Safety Roadster. We have here a
practicable spring frame without complication in design or working. On
the top of the rear forks there is a double link, connecting them with
the top of the seat pillar, which receives the saddle-pin. The lower
forks are horizontal, and are taken forward beyond the bracket; and
between the end and lower frame tube there is a strong coil spring.
The bracket, where the seat-pillar and front tube unite, is hinged, to
permit of a downward motion which is checked by the action of the
spring. This produces a very easy motion for the rider, and, so to
speak, smoothes the road, reducing concussion and vibration to a low
point. The front forks are double, and not continuous. The straight
ones run to within 3in. of the axle, and are connected by a spring
with the pilot wheel forks, to which they are pivoted in the centre;
this also helps to take the strain off the forks when the brake is
applied. The machine is a very good one, and with balls all parts,
etc., the price is £18."

Thanks for the reply. This is what I was counting on.

The first thing I've noticed was compression. This suspension is totally
compressed (bottomed) like it was pictured with heavy rider in the saddle.
Even modern xc full-suspension bikes suffer from low BB (small clearance)
but if you put "standard" length crank into this one it will plow field
nicely. The same about chain ring - it seems to be smaller than usual. Thus
maybe it wasn't a mistake just a set-up suggestion? Well exaggerated one.
BTW compare these cranks:

I'm familiar with the concept of safety bicycle. Polish word "rower"
(pronounced "rover") means bicycle.

In case of this velocipede we should redefine the term "full suspension".
Naming it rear suspended bike is a bit unfair in my opinion. Here is the
patent:
http://www.google.com/patents?id=FvBgAAAAEBAJ
Notice that it has been patented in England September 8 _1885_. It takes the
lead. However I'm unable to find the original patent.

Primitive - no telescoping or pivoting parts. It seems to be laterally stiff
though.

+ some rear suspension as well.

I can't find the patent. However I've found Don. Brazier as a witness in
http://www.google.com/patents?id=TsxWAAAAEBAJ

And now the dessert:
fully (almost) suspended fourwheeler
http://www.google.com/patents?id=_upWAAAAEBAJ

and my favorite although (probably) not suspended - a new kind of velocipede
http://v3.espacenet.com/textdoc?DB=EPODOC&IDX=GB190202557&F=0
or whatever it is.

I haven't been old bikes lover - rather a suspension geek. Now I see that
suspension is as old as bicycle. My explanation is that they needed it more
in 19th century that we need it today...

It would be nice to gather all this knowledge in one place to compare side
by side these very first ideas with highly engineered modern designs. Do you
(anyone) know if it is legal to use patent drawings for non-commercial web
site?

Thanks Carl. It's a great picture. This bike is very close to the original
Lallement design
http://www.google.com/patents?id=emkAAAAAEBAJ
Which is not strange considering they both lived in New Heaven CT in the
same time (186x).

Even if there is an earlier full-suspended bike it can't be much older.
