yes! I am working on an inertia driven bicycle in witch the forward motion of a weight suddenly stops and bicycle moves forward. I have not fully understood Weather there is any other advantage to this except there will be literally no physical drive to the gasoline bike.The model now in use utilizes a double pendulum which swings down and breaks in forward position.Of course power is needed to return pendulum to 1:00 position. The goal is to have a small gasoline engine driving a slow weighted flywheel which is weighted offset and breaks in forward position to launch bicycle forward with no chain,friction,or belt drive-james
