Abstract
A motor drive apparatus for a bicycle transmission includes a support; an interface member for coupling to a transmission actuating member that exerts a first force having a first force component in a first direction, wherein the interface member is mounted to the support for rotation around a rotational axis; a motor for coupling to the interface member; and a biasing mechanism for exerting a second force on the interface member having a second force component in a second direction opposite the first direction.
Claims24
A motor drive apparatus for a bicycle transmission comprising:
- a support;
- an interface member for coupling to a transmission actuating member that exerts a first force having a first force component in a first direction, wherein the interface member is mounted to the support for rotation around a rotational axis;
- a motor for moving the interface member;
- and
- a biasing mechanism for exerting a second force on the interface member having a second force component in a second direction opposite the first direction.
