[0031] first reference figure 1 and 2 , the bicycle 10 shown is equipped with a first embodiment of the present invention, as described below. Basically, bicycle 10 includes an electronically controlled drive train 12 mounted on a frame 14 having handlebars 16 and a pair of wheels 18 attached to frame 14 . Electronically controlled driveline 12 is controlled and operated in response to operation of rear shift operating device 20 and front shift operating device 22 . The shift operating devices 20 and 22 constitute first and second manual input devices constructed and arranged to include a first on (shift down) position ON1, a second on (upshift) position ON2 and an off (normal middle) position OFF.

[0032] Shift operating devices 20 and 22 are electrically connected to cycle computer 24 for controlling upshifts and downshifts of electronically controlled driveline 12 . Preferably, cycle computer 24 is electrically connected to a plurality of sensors that provide informati...

Abstract

A bicycle component is provided with a manual input device, and an input circuit having a signal line, a power line and a comparison section. The input circuit is especially useful in electronic shifting. The manual input device has a first ON position, a second ON position and an OFF position. The signal line produces a pair of input signals corresponding to the first and second ON positions. The comparison section produces pair of output signals based on a comparison of the input signals with a reference signal from the power line. Preferably, the input circuit includes a power saving mode.

Description

technical field [0001] The present invention generally relates to an input circuit. In particular, the invention relates to an input circuit for controlling an electronic bicycle component, such as an electronic shifter. Background technique [0002] Cycling is becoming an increasingly popular form of recreation as well as a mode of transportation. Additionally, cycling has become a very popular competitive sport for both amateur and professional sports. Whether the bicycle is used for recreational, transportation or competitive purposes, the bicycle industry is constantly improving the various components of the bicycle as well as the frame of the bicycle. One component that has undergone an in-depth redesign is the bicycle shifter. [0003] In recent years, bicycle components have become electronically controlled in order to increase the performance of the bicycle, as well as to facilitate the operation of the bicycle. In particular, bicycles feature electronic drive tr...
