Schwinn came out with cranks like this in the 1980's
It was called a "Bio-Crank"
The variation was not as extreme but it was the exact same concept.

This is not innovative. Elliptical chain rings have been around for a long time. I remember having one on my Look back in the mid 90s

The actual design is about 1400gr but we plan to go down to 1300 or lower after.

Currently I am testing PowerCranks for improving running .
What is the influence of your product ( if any ) on running performance ?
Any similarities to PowerCranks in biomechanical way ?

We don't have measured or evaluated yet the influence of our crankset on running performances. We hope to doing it in a near future with multi-sports athletes.
The biomechanical aspects of both products are quite different. Our crankset improved the wheel power by generating more torque (mostly in the power phase) while the Powercranks help to improved the upstroke/recovery phase.

My Kuwahara had that setup on it 15yrs ago. It was discontinued because your feet speedupand slow down every revolution and it is hard on the knees.

I agree about the feet speed variation over a complete rotation. But, the combination with oval chainrings creates a ergonomic, smooth and efficient movement. Like with a conventional crankset, a progressive training with a proper bike fit is very important.
