I have not tried the transformation of energy of shocks into energy of propulsion, it works only on the paper so far. It could not be perpetual motion, but I suppose 9/10 of the energy could be recovered.
But I'm using my prototype everyday and yes, obviously, the use of the whole muscle apparatus for propulsion gives more power. Some other people have tried and concurred.
Concerning the 10$, it covers the costs, but not yet one demand!
It took 30 years for the present back-wheel propulsion to beat the previous front-wheel propulsion, it might take all that much for my system. It's just the fate of some inventors.
Thanks anyway for your comments, which help me understand why no bike-maker takes this seriously.
