  Over ten years ago the ultimate fluid drive bicycle was invented by Douglas Brackett. This idea will transform that invention into the ultimate augmented drive cycling machine for commuters by introducing a micro-engine driven hydraulic rotory pump that feeds the same hub motor as does the variable piston pump driven by the pedal cranks. A control/relief valve will govern the top speed to meet legal requirements regardless the engine speed.
