System for manipulating a continuously variable transmission

A shifter for use on a bicycle having a continuously variable transmission (CVT) coupled to a drive wheel, the shifter comprising:

• a display located on a handlebar of the bicycle, the display comprising
• a scale configured to indicate a range of operating conditions of the bicycle, and
• a filament configured to change shape from a substantially flat line into a curved line as the operating condition of the bicycle is shifted from a high operating condition to a low operating condition, the steepness of the curved line corresponding to a continuously variable adjustment of the CVT.

A shifter for use with a continuously variable transmission (CVT), the shifter comprising:

• a display;
• and
• a filament extending between a first point and a second point, wherein at least the second point is movable relative to the first point to alter a distance between the first point and the second point and induce a deformation in the filament, and wherein a degree of deformation induced corresponds to a continuously variable adjustment of the CVT.
