Abstract
The bar-end electric actuation device of a bicycle gearshift, comprising a body suitable for being mounted at an end of handlebars facing forwards in the direction of travel (X) of the bicycle and a first and a second electric actuation member acting on respective electrical contacts which are mounted in the body and are suitable for controlling gearshifting, upwards and downwards respectively. The first and the second electric actuation member are faced by said body according to a respective facing direction, angularly spaced apart by an angle (α) that is between 60° and 130°. Moreover, the body is suitable for being positioned externally around the end of the handlebars, leaving free access to the inside of the end itself.

Bar-end electric actuation device of a bicycle gearshift, comprising:
- a body configured for being mounted at a forward facing free end of handlebars extending in a direction of travel (X) of said bicycle, said body extending forward in said direction of travel (X) when mounted, and two electric actuation members acting on respective electrical contacts which are mounted in said body for controlling gear shifting, upward or downward respectively, wherein said two electric actuation members are mounted on said body with respective facing directions that are perpendicular to a respective surface tangent to said body at a respective electric actuation member, said facing directions are angularly spaced apart by an angle (α) comprised between 60° and 130°;
- wherein a first one of said two electric actuation members faces upwardly and substantially perpendicular to said direction of travel (X) of said bicycle, and the first one of said two electric actuation members is more forward in said direction of travel (X) of said bicycle than a second one of said two electric actuation members.
Bar-end electric actuation device of a bicycle gearshift, comprising a body with a central opening extending between axial ends of the body that is configured to be mounted at an open tubular end of handlebars facing forwards in a direction of travel (X) of said bicycle and electric actuation members mounted on said body, each of said electric actuation members are configured to control gear shifting, upwards and downwards respectively, wherein said body defines a cylindrical through seat having an axis that, when the device is mounted on the open tubular end of the handlebars, extends in said direction of travel (X) of the bicycle, said cylindrical seat being configured to allow a positioning of said body on said open tubular end of said handlebars and retain free, uninterrupted access through a central opening of said body to an inside of said open tubular end.
A combination comprising:
- forward facing bicycle handlebars with a forward facing free end extending in a direction of travel (X) of a bicycle;
- and,
- an electric actuation device for controlling a bicycle gear shift, said device having a body configured for mounting at the forward facing free end of said handlebars and extending forward in said direction of travel (X) when mounted, and
- two electric actuation members that are mounted on said body in respective facing directions that are perpendicular to a respective surface tangent to said body at a respective electric actuation member, wherein said facing directions are angularly spaced apart by an angle (α) comprised between 60° and 130°;
- wherein said electric actuation members act on respective electrical contacts that control upward or downward gear shifting, wherein a first one of said two electric actuation members faces upwardly and substantially perpendicular to said direction of travel (X) of said bicycle, and the first one of said two electric actuation members is more forward in said direction of travel (X) of said bicycle than a second one of said two electric actuation members.
