Abstract

A bicycle electrical control circuit provides power and control signals to a plurality of bicycle components. The circuit comprises a power circuit that provides a power signal for the plurality of bicycle components, a control circuit that provides a control signal that controls at least one of the plurality of bicycle components, and a power stabilizing circuit (57) coupled to the power circuit. The power stabilizing circuit (57) stabilizes power provided from the power signal to at least one of the plurality of bicycle components.

Description

technical field [0001] The present invention relates to a driving device, in particular to a driving device for bicycle electrical components mounted on a bicycle to drive electrical components operated by electric power supplied from a power source. Background technique [0002] In recent years, various electrical components have been mounted on bicycles. For example, bicycles are equipped with electric components such as a so-called cycler computer that indicates the running state of the bicycle, or a control unit with a built-in shift computer for automatically shifting the speed changer. [0003] Conventionally, electric power has been supplied to such electrical components from batteries such as primary cells and storage batteries. When the number of electrical components increases, since the power supply is common, it is necessary to use power lines to connect from the power supply to multiple electrical components. transmission signal line. [0004] In the case of ...
