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: http://www.oldbike.com/Photo%20Gallery/Card3.jpg http://www.oldbike.com/Photo%20Gallery/Card4.jpg http://www.oldbike.com/Photo%20Gallery/Card5.jpg 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: http://www.oldbike.com/walthour3.jpg Same rider, reversed fork, but no pacer: http://www.oldbike.com/walthour.jpg *** 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

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? -paul

As the pacer also earns a title along with the rider, Walrave has at least 15 world championships.

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.
