I am 59 years old, married, the father of two married daughters with one grandson.

In the summer of 2003 decided that I wanted to lose some weight. I started a diet and also started to exercise. A short time later my future son in-law let me try a Rowbike that he borrowed from a friend. I quickly became addicted and purchased one myself.

After riding my new720 Sport Rowbike several hundred miles I wanted to go faster than the top speed of approximately 12.5 mph.

I also discovered that the first two speeds were not as useful as they should be for climbing hills. I wanted to improve the performance of the Rowbike.

Luckily, I live close to the Rowbike headquarters so I was able to meet in person with the Rowbike people. They were surprised that the change made such an improvement in the Rowbike’s performance. They also showed me that I had, in-fact, improved a couple of other issues, by accident, that I was not aware of.

Over the next two years I modified about a dozen prototypes. I then road tested these Rowbikes before they were made available to others to test ride.

I have one “Master Prototype” Rowbike that I have personally ridden for over 1100 miles. Together we tweaked and optimized the final design for production.

I’m proud to say that the new 2006 model incorporates all of my enhancements.

The Dave Cam improvements:

• My top speed while rowing has increased from about 12.5 to 22 mph astonishing 90 percent. Improvement
  
• The first two speeds now work more effectively so hill climbing is improved.
• Shifting is smoother.
• The catch (lag time) as you start a pulling on the power stroke has improved giving the rider more power, along with quicker starts.
• I added an “O” Ring to the chain/shock cord pulley at the bottom of the power lever.
