First bike – Marshall Saville:

    I first competed in the Fourth Annual IHPVA (International Human Powered Vehicle) championship race in May 1978 and placed 9th out of 30 riders. My average speed in the 200m time trial was 40.75mph.  My bike did not have a name and my brother, Wink Saville, was my helper.

    I also competed in the same event in 1979 using the same shell with a larger windshield and a bike with higher gearing. My average speed was 42.57 mph and I placed 6th overall out of 26 riders.  (Note:  this was years before the ASME HPV races started in 1983).

    The idea of entering the human powered speed championship was brought up during an ASME student project brainstorming meeting by Steve Ward, the president of ASME. I decided it would be an interesting project, so I signed up for it. It turned out I was the only one interested so I did it as a solo project.

    Since my time was limited, I went with a simple design aero shell over a standard bike. The shell frame was made of aluminum tubing pop riveted together with small gussets. The covering was doped polyester dress lining and I used an old motorcycle windshield.  I started construction 2 weeks before the event and finished at about 4 or 5 am on race day. I made a few passes down the street for check out and was totally amazed how fast I could ride.

    I also discovered that standard gearing was way too low and pedal rpm was limiting my speed. The first day of the event, my average speed was 36.3 mph. That evening, I installed a 56 tooth front sprocket and achieved 40.75 mph the next day.

    Interest in the human powered speed championship really picked up at Cal Poly in 1979, but unfortunately I had to transfer to another school after the fall quarter. I was not able to work on the 1979 multiple rider vehicle (Darla), but I was proud of what the team accomplished.

    Participating in HPV was a fantastic learning experience for me and fun at the same time as I am sure it has been for all the teams since then.
