The Pedal Powered Water Pump and Filtration System – “Water Bike” works with the individual sitting on the seat and placing one’s feet on the pedals. As the pedals begin to turn the chain attached to the pedals drives as set of gears, these gears are lined up and in mesh and they turn a shaft that is attached to an “overdrive” gearbox. The interaction with this gearbox through the shaft allows the shaft attached to the rubber vane pump to turn at a very high speed. This creates a partial vacuum in the hose that is in the dirty water. The vacuum draws water through the hose and into the spinning vane pump and into the stainless-steel tubing that is attached to the filtration unit. The dirty water moves through the 5-stage reverse osmosis unit cleaning the dirty contaminants out of the water. The water now exits the osmosis unit clean and fit for drinking. Pedalling at approximately 30 to 40 rpm every 30 to 40 seconds a half litre of clean drinking water is delivered.
