A bicycle control device is basically provided with a base member, a shift control unit, a non-shift operating lever, a first shift operating lever and a second shift operating lever. The shift control unit is mounted to the base member. The non-shift operating lever is movably coupled relative to the base member. The first and second shift operating levers are operatively coupled to the shift control unit. The second shift operating lever is a separate member from the first shift operating lever. The first and second shift operating levers are configured and arranged relative to each other such that the second shift operating lever is moved by the first shift operating lever when the first shift operating lever is operated.

Bicycle control device

A bicycle control device is basically provided with a base member, a shift control unit, a brake lever, a shift operating lever and a lever adjustment mechanism. The shift control unit is mounted to the base member. The brake lever is movably mounted relative to the base member. The shift operating lever is operatively coupled to the shift control unit to operate the shift control unit when the shift operating lever is moved from a rest position along a shift operating path. The shift operating lever is movable from the rest position along a non-shift movement path independently of the brake lever. The lever adjustment mechanism is operatively coupled to the shift operating lever to change a location of the rest position of the shift operating lever along the non-shift movement path.

A bicycle control device is basically provided with a base member, a shift control unit, a control member and a first shift operating lever. The shift control unit is mounted to the base member. The control member includes a first portion operatively coupled to the shift control unit and a second portion spaced from the first portion. The first shift operating lever is movably coupled relative to the base member to move along a first shift operating path and movably coupled relative to the base member to move along a non-shift operating path that is non-coincident with the first shift operating path. The first shift operating lever is slidably engaged with the second portion of the control member such that the second portion of the control member is moved when the first shift operating lever is moved along the non-shift operating path with sliding contact therebetween.

A position release mechanism for a bicycle control device comprises a positioning unit that is adapted to be biased in a first direction; a position maintaining mechanism that maintains the positioning unit in a plurality of predetermined positions; and a position releasing mechanism that moves in a position releasing direction, wherein the position releasing mechanism is operatively coupled to the position maintaining mechanism so that the positioning unit moves through at least two of the plurality of predetermined positions in the first direction in response to a progressive movement of the position releasing mechanism in the position releasing direction.

Method and apparatus for shifting a bicycle transmission by multiple steps

A control device is configured to be attached to the handlebar of a bicycle for controlling a brake mechanism and change speed mechanism. The control device comprises a bracket fixed to the handlebar, a brake lever pivotally coupled crosswise relative to the bracket and a release lever. The brake mechanism is controlled by fore and aft pivotal movement of the brake lever, while the change speed mechanism is controlled by sideways pivotal movement of the brake lever and the release lever. The brake lever and the release lever are further configured relative to the bracket for smooth easy operation by the rider.
