2007 Michigan HPV Rally

Dennis Grelk of Donnellson, Iowa, gets ready for the start of an event.  He won the stock class for the weekend on his homebuilt low racer.

By Mike Eliasohn

The 24th annual Michigan Human Powered Vehicle Rally June 23-24 attracted 38 riders and at least that many vehicles. There were two tandems and at least four riders competing with two or more vehicles.

It was Dennis Grelk’s weekend in more ways than one. He won the stock class on his homebuilt low racer. That class had the most entries, 16. Riding the Barracuda streamliner built by Warren Beauchamp, which Dennis now owns, he finished second in the streamliner class behind John Simon in his Moby. And riding a Bachetta Corsa, Dennis also competed in the urban transportation contest.

The 38 riders was an improvement over the 29 we had last year, Many of the regulars were missing, but we had several newcomers, including a contingent of low racers from Ohio recruited by MHPVA President Wally Kiehler at the Calvin’s Challenge ride in Ohio.
Also encouraging were the 34 vehicles and 32 riders competing in the Sunday events. (Three riders competed with two vehicles and there was one tandem.)

In addition to Ohio, Iowa, and Michigan, of course, riders came from Iowa (Dennis Grelk), Ontario (Jim Iwaskow), Indiana and Illinois.

This was the first year we gave cash prizes instead of merchandise. Nobody kept track of who got how much, but the total, coming from entry fees, was $335.

Dan Thorne and his daughter, Julie Pitko, of Sault Ste. Marie on their way to 29.9 mph in the 200-foot sprint event.  Riding a WizWheelz tandem, they were first in the tandem class for the weekend and also won the urban transportation contest. (What was WizWheelz is now TerraTrike, based in Grand Rapids.)

The first event was the one hour. In the streamliner class, Dennis edged out John Simon of Portland, 31.5 miles to 31.2 miles. In the second one-hour, Dennis won first place in the stock class on his homebuilt front-wheel-drive low racer, 26.7 miles.

Other class winners were: superstreet, Mike Mowett, St. Clair Shores, on his upright Cervelo with fairing and body sock, 24.9 miles; superstock, Chris Cortez, Chicago, on a Rick Gritters-built low racer, 23.6 miles; tandem, Bob Teregan and Merlin Elsner, Warren, on a Rans Screamer, 19.9 miles; women, Dora Cortez, Chicago, Optima Baron, 19.5 miles; and junior, Ryan Miller, Vandalia, Ohio, upright bike, 17.4 miles.

The first event after lunch Saturday was the the hill climb-coast down. Scott Forthofer of St. Clair Shores had the third best time ever going up the hill to win the stock class, 18.69 seconds, on his upright Softride Powerwing. (Thanks to Mike Mowett for keeping track of the records.) The other class winners were: Superstreet, Mike Mowett, 19.97 seconds; superstock, Paul Bruneau, Portage, Velokraft VK2; 22.35 seconds; junior, Nick Myers, Holly, Maserati upright bike, 24.72 seconds; streamliner, John Simon, 24.78 seconds; tandem, Teregan/Elsner, 24.97 seconds; and women, Amy Miller, Vandalia, Ohio, Bianchi upright bike, 28 seconds.

At the top of the hill, competitors stopped pedaling and then coasted. Winners were: Streamliner, John Simon; stock, Thom Ollinger, West Milton, Ohio, Velokraft NoCom; superstreet, David “Doc” Pearson, Mooresville, Ind., Infinity front-wheel-drive; superstock, Chris Cortez; women, Dora Cortez; tandem, Teregan/Elsner; and junior, Nick Myers.
Saturday's final event was the standing start 1-kilometer time trial: Streamliner, John Simon, speed at end, 29.5 mph; stock, Dennis Grelk, 28.9 mph; superstreet, Mike Mowett, 27.9 mph; superstock, Paul Bruneau, 26.5 mph; tandem, Teregan/Mike Mowett (subbing for Merlin Elsner, who had to leave early), 24.5 mph; women, Dora Cortez, 21.6 mph; and junior, Nick Myers, 19.2 mph.

Dora Cortez of Chicago finished first in the women's class for the weekend on her Optima Baron.  Her speed in the 200-foot sprint, shown here, was 28.5 mph.

Sunday started with the 200-foot sprints. Frank Geyer of Brighton has his one good run of the weekend by winning the streamliner class in the Rick Wianecki-built Frank-n-Liner, 43.6 mph. Other class winners were: Stock, Thom Ollinger, 36.7 mph; superstreet, Mike Mowett, 34.1 mph; superstock, Chris Cortez, 33.8 mph; tandem, the father/daughter duo of Dan Thorne and Julie Pitko, Sault Ste. Marie, on their WizWheelz tandem tricycle, 29.9 mph; women, Dora Cortez, 28.5 mph; and junior, Nick Myers, 21.4 mph.

Garrie Hill generously posted some cash prizes for the 200-foot sprints. Here's his description of the prizes: “The GeeBee Cup cash awards for the 200-foot sprints this year were for the top speed in streamliner, stock (male), stock (female). I'd originally said that the winners would receive their speed in cash, i.e. 29.33 mph would win $29.33. There would be an additional cash bonus for speeds "above and beyond" certain numbers (which I don't remember) I listed (somewhere!). I do remember the streamliner mark was 45 mph. Frank Geyer posted a top speed of 43.56 mph. I presented him with $75 because he managed to turn in that speed after crashing the new Frank-n-Liner about 15 times in launching! Dora Cortez got $75 for her effort of 28.52 mph because I was feeling generous, and still laughing from Frank's escapades. Thom Ollinger received $75 for his 36.65 mph run because he proved that putting an old guy (Thom) on a fast machine (my NoCom) does make the old guy fast!”

The final events were the two road races using the .624 mile short course, which does not include the hill.

Entrants line up for the start of the 20-lap road race on Sunday morning.  John Simon of Portland in the red Moby at far right won the race and the streamliner class for the weekend.

John Simon won the 20-lap race in his Moby streamliner at an average speed of 27.8 mph, followed by Dennis Grelk on his stock class lowracer, with Warren Beauchamp on his Velocraft NoCom in third.

Wally Kiehler on his superstreet class Lightning F40 won the 15-lap road race at an average speed of 21.7 mph, followed by Scott Forthofer on his stock class Softride upright bike second and David “Doc” Pearson third in in his superstreet Infinity.

First and second class overall in each class were: Streamliner (5 entries) – 1) John Simon, 285 points; 2) Dennis Grelk, 280. Superstreet (5 entries) – 1) Mike Mowett, 295 points, 2) Jeff Hunn, North Manchester, Ind., Reynolds TiCuda, 265. Superstock (4 entries) – 1) Paul Bruneau, 285 points, 2) Chris Cortez, 280. Stock (16 entries) – Dennis Grelk, 275 points, 2) Thom Ollinger, 259. Junior (2 entries) – Nick Myers, 295; Ryan Miller, 280. Women (4 entries) – 1) Dora Cortez, 295 points; 2) Amy Miller, 275. Tandem (2 entries) – Dan Thorne/Julie Pitko, 280 points, 2) Bob Teregan/Merlin Elsner, 240.

As the sole judge for the “best homebuilt prize, I (Mike E.) couldn't make up my mind, so $10 was given to Warren Beauchamp of Big Rock, Ill., builder of the Cuda-W streamliner, and Jim Iwaskow of Richmond Hill, Ontario, builder of the Figure 8 carbon fiber short wheelbase.
Niether bike is new. Jim built his short wheelbase bike in 2002, but has made improvement since. He shaped the frame out of foam, then covered it with carbon fiber. He also make the fork, seat and handlebar mast from carbon fiber. (the mast and, I think, the fork have since been replaced.) New this year was the tailbox. He first made a plug, then a mold, then a single layer of carbon fiber (or fiberglass – I neglected to write it down) inside the mold. The tailbox weighs 5.5 pounds. The bike, 24 pounds. The rear wheel is 700c; the front, 20 in.

Reg Rodaro of Niagara-on-the-Lake, Ontario, built the plug, female mold and fairing to Warren's design. Warren did the rest, including the front subframe that bolts to the monocoque. It's a front-wheel-drive, with gearing provided by a 14-speed Rohloff Speedhub driving a 406mm (20-inch) wheel. The rear wheel is a 700c that bolts to dropouts that bolt to the monocoque.

In 2005, Warren pedaled the Cuda W to 64.4 mph at Battle Mountain, Nevada. As of the rally, he still have front and rear wheel fairings to make and was still fiddling with the subframe.
If you want to see the entire building process for the Cuda W, go to (of which Warren is the Webmaster), then click on “recumbent building,” then “human powered vehicle research and development,” then on “Reg Rodaro builds the Cuda-W.”

Other homebuilts of note at the rally – there aren't many of them these days – included Dennis Grelk's stock class entry, previously mentioned, and the Rick Wianecki/Frank Geyer Frank-n-Speed streamliner that was still experiencing teething problems.

Frank Geyer of Brighton and Rick Wianecki of Okemos experienced a lot of problems with the new Frank-n-Liner built by Rick.  But Frank did have one good event – first place in the streamliner class in the 200-foot sprints and top speed of the rally at 43.6 mph.

Mike E:
I think this was a very good summary of our successful 24th annual MHPVA event. Keep up the good work and will see you at our February Winter Meeting.
