Today’s bicycles show similar transmission systems based in a cogwheel, placed about the middle of the bicycle and driven by two pedals in a circular alternated movement. This movement is then transmitted to the back wheel by a roller chain. This system, although wasting a part of the employed force, works well so it has been kept as it is along the years.
However, there are other possible ways to convert the muscular power of the cyclist into the vehicle movement, for instance the system proposed by the present invention.

This invention discloses a new transmission system which is based in linear alternated inputs, by contrast with the circular movements of the classic transmission systems. The system converts linear movement in rotation movement. The linear movement may be done by human or machine force.
This system improves the efficiency of the mechanical transmission thus increasing its effective output power.

Potential Commercial Use / Applications
This invention can be applied in bicycles and other vehicles, systems or machines that are powered by movement conversion. A demonstration prototype was built and tested.
In addition, a bicycle equipped with this system can be used by short and taller cyclists with the same efficiency without having to make adjustments other besides the seat height.
