## Abstract

A highly adaptable user interface for gearing based bicycle power transmission devices powered by a linear servo actuator slaved to an electronic control system serving to automatically shift into desirable gearing ratios under user predefined shifting criteria adaptable in real time to rider conditioning, comfort level and road conditions thereby alleviating manual shifting tasks and achieving optimal pedal rate and effort settings for the rider. Ability to switch to manual mode augments rider total control of disclosed device.

## Claims

### Claim 1

A bicycle gearbox shifter user interface comprising:
d) an electrically powered touchscreen display including a “teach mode” screen, a “programming mode” screen, and an “operation mode” screen,
h) said “teach mode” screen including a “teach position” display window depicting a “shift position” selection, and a “shift in” and “shift out” buttons for accurate positioning of a shifting linkage of a bicycle gearbox for said “shift position”,
i) said “programming mode” screen including a “shift position” display window depicting selection to program, and a “set” button for programming of a respective “shift speed” of a bicycle,
j) said “programming mode” screen additionally including a “shift up mode” button permitting limiting said programmed shift speeds solely to upshifting and a “shift down mode” button limiting said programmed shift speeds solely to downshifting,
k) said “programming mode” screen further including a “skip” button permitting limiting number of “shift positions”, and
l) said “operation mode” screen including a “shift position” override “shift up” and “shift down” buttons,
Whereby said user interface enables a user to define a “shift speed” for each “shift position” of said bicycle in an exacting manner to suit individual need.

### Claim 2 (depends on 1)

The user interface of claim 1 wherein said “operation mode” screen include a sliding control bar for attenuation of said programmed “shift speeds” for said “shift positions”.

### Claim 3 (depends on 1)

The user interface of claim 1 further including buttons for definition and selection of multiple “shift speed” programs.

### Claim 4

The process for teaching, programming and operation of a geared bicycle shifter comprising:
d) providing an electrically powered touchscreen display with a “teach mode” screen, a “programming mode” screen, and an “operation mode” screen,
h) providing said “teach mode” screen with a “teach position” display window depicting a “shift position” selection, and a “shift in” and “shift out” buttons for accurate positioning of a shifting linkage of a bicycle gearbox for said “shift position”,
i) providing said “programming mode” screen with a “shift position” display window depicting selection to program and a “set” button for programming of a respective “shift speed”, and
j) providing said “programming mode” with an additional “shift up mode” button permitting limiting of said programmed shift speeds solely to upshifting and a “shift down mode” button for limiting said programmed shift speeds solely to downshifting,
k) providing said “programming mode” with an additional “Skip” button permitting limiting number of “shift positions”, and
l) providing said “operation mode” screen with a position override “shift up” and “shift down” buttons,
Whereby said process enables a user to define a bicycle “shift speed” for each “shift position” in an exacting manner to suit individual need.

### Claim 5 (depends on 4)

The process for teaching, programming and operation of a geared bicycle shifter of claim 4 further provided with a sliding control bar capability for attenuation of said programmed “shift speeds” for said “shift positions”.

### Claim 6 (depends on 4)

The process for teaching, programming and operation of a geared bicycle shifter of claim 4 further provided with an additional capability to define, save and run multiple shifting programs.
