<p>A bicycle control device includes a base member (1) adapted to be mounted to a structural member of a bicycle, a dial (2) rotatably mounted to the base member (1), a detent mechanism operatively associated with the dial (2) for providing a detenting force to the dial (2) at a plurality of rotational positions of the dial (2) , and a first electromagnetic switching member (22) operated by the dial (2) for selectively electromagnetically communicating with a second electromagnetic switching member (13) when the dial (2) is positioned at each of the plurality of rotational positions. A button (4,5) and/or display (3) may be disposed in proximity to the dial (2) to allow the rider to control the bicycle transmission and to view the status of the selected gears, respectively. <IMAGE></p> |
