D'oh!

I'd browsed past these photos before, but I didn't notice that the
forks are reversed to let the rider get a tiny bit closer when
drafting a pacer:

I haven't found a picture of a reversed fork in action yet, but these
pictures show how close the rider with a straight fork was to the back
of the pacer, and the small front wheel that helped him get an inch or
two closer:

Same rider, reversed fork, but no pacer:

Pictures of tandem motorcycle pacers puzzled me:

http://www.oldbike.com/Photo%20Gallery/motorcycle2.jpg

Why the hell would you need two men on a _motorized_ pacer?

I always assumed that it was a matter of the big guy on the back being
able to sit up straight as far back as possible. Imagine the draft
behind a small woman (wife or girlfriend) perched in the middle of a
Vespa. Now imagine Chalo perched on the license plate of a modern
motorcycle.

But more draft is only part of the reason for putting two men on an
early motor pacer, where a windshield would have been cheaper and
simpler than an extra rider.

The text here explains the real reason for the early two-man pacers:

"He [Walthour] purchased a motor tandem from the Orient Cycle Company
in Waltham, Mass. to use in the races. It was a huge machine weighing
nearly 300 pounds and geared to 170 inches. With each turn of the
cranks it would travel half a block. It was the first motorized
machine in the state of Georgia. The purpose of being a tandem was so
that one man could steer while the other would operate the motor."

http://www.oldbike.com/Walthour.html

The first motorcycle pacers were so clunky and awkward that they
needed a pilot and an engineer!

Later pacers were improved so that the rider could sit upright and
all the way back for good drafting, but still steer and run the engine
single-handed. Here's a more modern single-seater:

http://www.printsoldandrare.com/bicycles/145bike.jpg

They often wore heavy knee-length coats. The coats might have helped
if it was cold, zooming around a track at high speed just sitting on a
motorcycle, while the bicyclist behind was out of the wind and stayed
warm by pedaling. But the long dusters probably also improved the
draft for the bicyclist.

Here's another two-man with an engine operator behind the pilot:


http://www.nostalgic.net/index.asp?S=arc/pre1920/1901+bicycle+racing+postcard%2Ejpg

Notice that the engine above is so feeble that the pilot has pedals to
help get it all going--another reason for two men.

In the picture below, an Orient tandem with stoker, circa 1900, _both_
engineer and pilot have pedals to get the thing going:

http://www.statnekov.com/motorcycles/book-photos/orient-tandem-pacer.jpg

A similar Hedstrom tandem pacer with pedals for all hands (sorry,
couldn't resist it):

http://www.statnekov.com/motorcycles/book-photos/hedstrom-tandem-pacer.jpg

The next five pictures show similar tandem pacers with pedals for both
the engineer and the pilot to help the huge but feeble engine:

http://www.oldbike.com/Photo%20Gallery/i1_B_L.jpg

http://www.oldbike.com/Photo%20Gallery/i1_B_L2.jpg

http://www.oldbike.com/Photo%20Gallery/i1_B_L3.jpg

http://www.oldbike.com/Photo%20Gallery/i1_B_L4.jpg

http://www.oldbike.com/Photo%20Gallery/i1_B_L5.jpg

Note in the first two pictures how the bicyclist literally uses his
head--instead of a back bar preventing him from running into the rear
wheel, he just leans his forehead against the back of the engineer
sitting bolt upright on the back of the pacer.

It took wives on Vespas about a century to replace all this.

Cheers,

Carl Fogel

Those old timers had a lot of spine.

Do you know any reason, Carl, why the pace bikes couldn't be fitted with
a large sheet of metal perpendicular to the direction of travel? That
would seem to me to provide better draft. Alternatively, you could
fashion a sort of fairing off the rear end of the motorcycle for the
bicycle to fit into.

I'm sure these ideas must have been considered. Were there rules of some
sort here?

Like Oscar Egg's pointy butt fairing? These sorts of things get banned
promptly as developed.

Dear Paul,

D'oh!

I stumbled across the mother lode of pacer pictures, over a thousand.

A helmet verging on becoming a windshield:

http://imageevent.com/dernysportuk/stayerpictures?p=87&w=4&n=1&c=2&m=-1&s=0&y=1&z=2&l=0

A 1938 pacer with reversed fork, small front wheel--and a modest metal
sheet:

http://imageevent.com/dernysportuk/stayerpictures?p=1124&w=4&c=2&n=0&m=-1&s=0&y=1&z=2&l=0

An even better windshield:

http://imageevent.com/dernysportuk/stayerpictures?p=1141&w=4&c=2&n=0&m=-1&s=0&y=1&z=2&l=0

The actual bike not only had the monster front sprocket, but also a
front seat adjuster/brace:

http://imageevent.com/dernysportuk/stayerpictures?p=1142&w=4&c=2&n=0&m=-1&s=0&y=1&z=2&l=0

Another front seat adjuster/brace:

http://imageevent.com/dernysportuk/stayerpictures?p=1159&w=4&n=1&c=2&m=-1&s=0&y=1&z=2&l=0

Front seat _and_ handlebar adjuster/brace:

http://imageevent.com/dernysportuk/stayerpictures?p=1226&w=4&c=2&n=0&m=-1&s=0&y=1&z=2&l=0

Side view:

http://imageevent.com/dernysportuk/stayerpictures?p=1227&w=4&c=2&n=0&m=-1&s=0&y=1&z=2&l=0

More modern version of same adjuster/brace:

http://imageevent.com/dernysportuk/stayerpictures?p=1229&w=4&c=2&n=0&m=-1&s=0&y=1&z=2&l=0

Good picture of pedal-powered pacer:

http://imageevent.com/dernysportuk/stayerpictures?p=1175&w=4&c=2&n=0&m=-1&s=0&y=1&z=2&l=0

Pacer podium girls (the real podium girls are wearing high heels and
bikinis and drafting behind the clogs and long dresses):

I can't say exactly why the ridge goes across the top of the helmet, but the
"ridge" in open in the back to allow the pacer to hear verbal commands from
the rider.

BrunoWalrave is the pre-eminent motorpace driver in the modern era. As the
pacer also earns a title along with the rider, Walrave has at least 15 world
championships.

Dear Paul,

I don't know if there were (or are) any rules against mounting the
equivalent of a motorcycle windshield on the back of a pacer.

A rider sitting well back and bolt upright on a weirdly modified
motorcycle is good enough to get the job done--the bicyclist goes much
faster.

Modern derny pacers still use nothing but a rider with no special
fairing.

The original pacers were just tandem bicycles, so there was a
tradition of not using special fairings:

http://i5.tinypic.com/5y1u6ba.jpg

Here's a pair of old pacer-bicyclist teams getting ready to race, all
wearing helmets:

http://oldroads.com/pqdb_img.asp?p=http://members.aol.com/menotomy6/disp/race.gif&mod=&mak=Race_at_Revere_Beach,_MA

Here's Major Taylor behind a one-man pacer, with both men wearing odd
helmets:

http://i8.tinypic.com/4katr9f.jpg

Embarrassingly I failed to notice Taylor's reversed fork and small
front wheel when I posted that picture months ago. The mystifying
gadgetry in the pacer rider's lap makes it easy to understand why
earlier pacers needed a second rider to run the engine.

Cheers,

Carl Fogel

The rules that govern motor-paced events are set by the UCI. Among the
things covered in those rules include the dimensions of the pacing
vehicle as well as the permissible attire worn by the motor-pacer. See
chapter 6 (Equipment and Infrastructure) in the section related to
track events:

Hey, look at the pacer, it's the preznut!

Gowd bleh 'merica!
