Today was a bit of a milestone for me in that it was the last day that I was a department chair (after ten years). As a result, my office is a bit of a mess right now. I have until next weekend to finish vacating my current office.

One thing that I can look forward to is a bit more time to bike. So far this year, I’ve logged 181 consecutive days of biking, actually part of a streak that goes back to Dec 23 of last year. However, I haven’t really been able to log many long rides. I’m planning to do RSVP this year, so this is a bit of an issue.

The other thing that I can do is be involved a bit more with the bike team, and actually learning a thing or two about composite fabrication before certain people graduate. Here is a picture from a while ago showing some of the molds for frame components.

Here is the first official piece of the frame for the new bike

and here are some sketches of things that the team is not going to build.

I celebrated today by spending a little time at the bike shop. They can always find something for me to do that requires only unskilled labour.

After bikebike! the team left Tempest in my office for quite a while.

They finally came by and picked it up to take back to McCaul. Thanks Bill and Evan!

At McCaul, team alum Thomas was patching his steel touring bike, with carbon of course!

I also noticed this steel rail which was new. I was told that it was for calibration.

In the meantime, the build of our new WHPSC bike progresses, and the team is also considering what to build for ASME next year.

ASME 2019: Day 3

Today was the big day for the endurance race. Here is the crowd getting organized for the group shot.

Props to Rose Hulman for lifting their bike with rider.

Bill gets in on the bike lifting action.

Rena and Bill get in some practice on the course.

And here we go! the LeMans start.

We are seeded first, as determined by our position from the Womens’ sprint. Bill gets a much quicker start than everyone else.

Last year’s winner: South Dakota State.

She came in a little too hot into the hairpin turn and went over. Fortunately she was OK.

Bill taking the hairpin.

Two tilting trikes in the competition: this one from Missouri S&T.

This one from UW-Milwaukee.

Bill switches with Calvin.

Our bike can corner tighter than some.

This padding was added to the prone bike since yesterday. I was told after the race that it didn’t help much.

Now it’s Rena’s turn.

Traffic jam leading up to the hairpin.

#15 is determined to finish.

Rena in the hairpin. SDSU was trying to keep up with her for her entire shift.

On the aerobars..


Grocery dropoff.

In the meantime, the team from Puerto Rico is dancing up a storm in the pits.

MSE leading Harvard.

Rena into the pits after her shift.

Off goes Josh.

Josh takes the checkered flag. We finished 7 laps higher than the next closest team.

Home team MSU was our neighbour in the pits.

On the other side, perennial powerhouse team M S&T, plus a bonus egyptian team.

The team post race.

Alumni Thomas and Bruce join in on the fun.

Luke takes a few hot laps since he didn’t get to ride during the race.

Now the awards.

Rena: 1st place Womens’ sprint.
Calvin: 1st place Mens’ sprint.

1st place endurance race.

Overall, the team finished 2nd. Hats off to Ohio U who were first, beating us by less than one point out of 88. They were first in design. For our report, there was a penalty assessed for not having a rollover protection system, which contributed to us only being 4th on design. We had hoped to make up the difference in the dynamic events. Also props to Akron for their pretty bike and the photo finishes with Calvin in the mens’ sprint. Official results here

This was also the first time that we won all the dynamic events, AFAIK.

The team had speculated that with the evolution of the HPVC away from speed, and with the addition of many obstacles to the endurance race, that an ordinary bike would do well. I think that this was fully demonstrated this year.

Special kudos to team captain Bill Kong who brought this idea to fruition, and who expended a huge effort in the past three weeks to get the new bike done.

We’ll regroup after this event to decide what comes next for our team.

ASME2019: Day 2

Day 2 dawns a bit foggy. It’s time for the mens’ and women’s sprints. Here we are at the drivers’ meeting.

Now the riders walk the very short, and somewhat curved course, which is also ridden with potholes. I was told that the MSE police changed the sprint venue at the last minute.

We lead off with the qualifying rounds for women. All racers are timed, and then the top sixteen vehicles move on to the double elimination rounds. Here is SDSU, last year’s winner.

Alabama.

Alexandria, and Akron.

The prone bike from Binghamton.

Rena at the start

And she’s off.

You’ll note that we decided to run without fairings. The front fairing was always going to be somewhat problematic in that it could interfere with control. The rear fairing, which was designed with a compartment to carry groceries, failed earlier in the morning, so we ran without that as well.

She did really well and ended up seeded in first place. We start hearing grumbling about how we shouldn’t be allowed to enter an ordinary bike.

Then they did several rounds of head to head racing, and Rena ended up at the top of group A. The women’s finals would be run after the men qualified and ran some rounds of elimination.

Here the men start lining up.

Kudos to these riders whose chains both broke at the start, and then they picked their vehicles up and ran down the course.

Yes that is a badger from Madison.

It was a pleasure to see some old friends from the Michigan HPV crowd. From left to right: Mike E, Mike M, Rick W, and Tim.

This kid from Ohio University was riding a belt drive recumbent that was built by a former faculty member.

Calvin lines up for his first run.

and he’s off.

He also made fairly short work of most of the other vehicles, but he lost a close one to Akron.

By losing, he ended up in the “B” bracket, and was able to keep racing. Here he is enough ahead of a vechicle that he stopped pedaling.

Here is Rena taking the checkered flag in the Womens’ final. Great work Rena!

In the men’s final, Calvin was up against Akron again, and it was an absolute photo finish.

The judges are looking at video to see who one. Turn’s out it was Calvin.

This photo from Tim Potter shows how close it was.

and here is an official video.

This meant that both Toronto are Akron had lost once, and so they had to immediately run a grudge match to see who got to be in first place. This time it was close, but not as close as the last, as Calvin pulls out another win.

A great result for the team: 1st in both women’s and mens’ sprints, the first time the team has achieved this. Overall, our design report was fourth, and Ohio was first in design and just behind us in the sprints, and so they are still in first place. We’ll see how everyone does in the enduro.

After a hard day’s work, its time for ice cream at the MSU diary store.

This was the only HPVC vehicle that we saw that was ridden to the dairy store.

For dinner, I introduced the team to the wonders of the Brody Hall dining area.

Early to bed so that we are in shape for tomorrow’s racing and the drive home. A great day for the team (photo: Tim Potter)

ASME 2019: Day 1

Friday is a day for making the design presentation, and passing static inspection and safety.

Here is the bike with the fairings mounted.

The spacing between the front and rear fairings is a bit tight for Bill.

Calvin trimming the rear fairing.

That’s a bit better.

Going over to safety, we get a first look at some of the other bikes.

Rose Hulman with a massive front roll bar. The rear one is built into the tail fairing.

Our hosts, Michigan State University with their first time HPV entry

SUNY Binghamton was inspired by Graeme Obree to build a prone bike. Nice big chainring. How the rider is going to get out of the harness to load groceries is beyond me.

Bingham going through the rollover test.

UW-Milwaukee’s interesting tilting trike.

Calvin making a little noise on his trainer at the evening showcase.

Looks like we’re ready to go. Saturday is the sprint event.

ASME HPVC T minus 6 days

The annual ASME competition for human powered vehicles starts in just 6 days. This competition, rebranded the “North” competition, will be at Michigan State University, my old stomping grounds.

This time around, HPVDT decided past fall to try something new: to build a bike that was basically a conventional bike, but with some fairing to improve aerodynamics. Here are some pictures of the concept, named Zephyr.

As per the team’s usual MO, the build started much slower than planned, and it was only in the past month or so that things really started rolling. Here is a picture of the male plug for the front fairing.

Male forms roughed out for the frame, and a trispoke wheel.

Prepping the forms so that fibreglass molds can be pulled off of them.

Luke and Bill plan the frame jig.

Layup of the mold for the frame.

Laying up the wheel mold.

The first attempt at making the frame. This one was deemed not usable.

The second one in the jig, with the chainstays and seatstays roughly positioned.

The basic chassis of the bike in rideable condition so that production of the safety video, and the final rider training can begin. Bill really pulled things together to get things this far.

Production continues on the front and rear fairing.

Just to show you that we are not the only team to pull things together at the last minute, this is the super mileage team working on their vehicle body the afternoon before they were due to start driving to their competition in Sonoma, California. Wishing them good luck and safe travels!

and just as a bonus, here are some pictures of the start of the build for this year’s bike for Battle Mountain.

I”m looking forward to seeing some old friends and colleagues at the competition. Not wanting to jinx State, but if they win this Sunday’s basketball game, next weekend in East Lansing is going to be crazy.
