A shifter for use with a continuously variable transmission includes a grip portion and a hub portion. Specifically, the shifter is designed for use on a bicycle, but could also be used with any light vehicle. The grip portion is characterized by a rotatable adjuster that is coupled to a cable. The cable is also coupled to a hub portion. As the adjuster is rotated, the cable is pulled, in turn rotating a pulley assembly in the hub portion. As the pulley assembly is rotated, it advances a rod within a continuously variable transmission. The rod adjusts the power adjusters as described above. The grip portion is also unique in its display of information to the rider. The grip portion includes a display showing the ratio of input to output. The display also includes a filament that curves as the ration is adjusted. A high ratio renders the filament flat while the filament takes on a steep curve as the ratio is adjusted to make riding up hills easier.

1. A shifter for use with a continuously variable transmission (CVT), the shifter comprising: a display having a filament that is moveable from a first position to a second position, the filament comprising a flexible member, at least a portion of the flexible member visible within the display;a scale for indicating a range of operating conditions for the CVT; andwherein a flexion in the visible portion of the flexible member relative to the scale corresponds to a continuously variable adjustment of the CVT. 2. The shifter of claim 1, wherein an adjustment of the shifter further adjusts a ratio between an input force and an output force. 3. The shifter of claim 1, further comprising a rotatable hand grip. 4. The shifter of claim 3, wherein the rotatable hand grip further comprises: an inner case;a grip pulley engaged over the inner case,wherein the grip pulley is rotatable around the inner case;wherein the grip pulley has a geared portion; anda lead screw also having a geared portion for mating with the grip pulley; wherein the filament is coupled to the lead screw by a following nut. 5. The shifter of claim 4, wherein the filament has a first end coupled to the nut and a second end coupled to the inner case, so that a movement of the nut produces flexion in the filament. 6. The shifter of claim 1, wherein the flexible member extends between a first end and a second end, at least one of the first end and the second end moveable along the scale, and wherein varying the distance between the first end and the second end induces flexion in the visible portion of the flexible member. 7. The shifter of claim 6, wherein the distance between the first end and the second varies between a maximum distance and a minimum distance, the visible portion of the flexible member comprising a substantially flat line at the maximum distance, the visible portion of the flexible member comprising a curved line at the minimum distance. 8. The shifter of claim 7, wherein the flexible member comprising a substantially flat line indicates a high ratio operating condition of the CVT, and wherein the flexible member comprising a curved line indicates a low ratio operating condition of the CVT. 9. 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, anda 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. 10. The shifter of claim 9, further comprising a rotatable hand grip coupled to the handlebar of the bicycle. 11. The shifter of claim 9, wherein an adjustment of the shifter further adjusts a ratio between an input force and an output force. 12. The shifter of claim 9, wherein the rotatable hand grip further comprises: an inner case;a grip pulley engaged over the inner case,wherein the grip pulley is rotatable around the inner case;wherein the grip pulley has a geared portion; anda lead screw also having a geared portion for mating with the grip pulley; wherein the filament is coupled to the lead screw by a following nut. 13. The shifter of claim 9, wherein the substantially flat line corresponds to the highest operating condition in the range of operating conditions. 14. The shifter of claim 13, wherein the filament has a first end coupled to a following nut and a second end coupled to an inner case, and wherein a movement of the following nut moves the first end toward the second end and increases the steepness of the curved line of the filament. 15. The shifter of claim 9, wherein the filament extends between a moveable first end and a stationary second end, and wherein moving the first end closer to the second end changes the shape of the filament from a substantially flat line into a curved line, the steepness of the curved line increasing as the first end moves closer to the second end. 16. The shifter of claim 15, wherein the filament comprises an arrow configured to move from left to right along the scale as the first end of the filament moves closer to the second end of the filament. 17. The shifter of claim 16, wherein the first end of the filament engages a following nut configured to advance or retreat along a lead screw, the lead screw driven by a rotatable adjuster configured to adjust a ratio between an input force and an output force of the CVT. 18. A shifter for use with a continuously variable transmission (CVT), the shifter comprising: a display; anda 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. 19. The shifter of claim 18, wherein the second point is coupled to a following nut. 20. The shifter of claim 18, wherein the distance between the first point and the second point corresponds to the continuously variable adjustment of the CVT.
