ABSTRACT:
By incorporating an infinitely adjustable, variable speed transmission unit into a bicycle driving mechanism, it becomes possible to vary the speed of the bicycle in a very easy and continuous manner from any predetermined maximum value of rotation in the forward direction to zero. By using a similar, infinitely adjustable, variable speed transmission unit in combination with a standard, two speed and reverse gear box, a very efficient automotive transmission system is also achieved, having a stepless speed control with a large power input.
