Having already developed a very good circular pedal stroke on both fixed wheel track bikes and my primary road and time trial machines I found them uncomfortable and developed pain behind my knee-caps, which is a sign that the seat is too low. Further research after I had taken a half ownership in 3 bicycle stores found these were targeted only at the novice market, who actually did get benefit from the design. As an aside I retired from competitive cycling to study Engineering, only to suffer crippling nerve damage as my career was peaking so I no longer work or cycle, although I am still very interested in developing cycling technologies.

I must say though, to be fair to the modified car enthusiast, it is far more difficult and expensive to do any serious engineering changes to a legally road registered vehicle.
