The invention provides a bicycle electronic rear derailleur and a bicycle. A first base end of a base unit is used for being connected to the bicycle, and a guide part is formed at a second base end of the base unit; a follow-up part is formed at the first moving end of the movable unit, and the second moving end of the movable unit is used for being connected with the chain guide unit; when the driving unit drives the movable unit to move close to or away from the base unit, the follow-up component moves along the guide component; in the process that the driving unit drives the movable unit to approach the chain wheel unit, the second end of the movable unit swings in the direction away from the axis of the chain wheel unit. In the process that the driving unit drives the movable unit to be away from the chain wheel unit, the second end of the movable unit swings in the direction close to the axis of the chain wheel unit. The mechanism is simple in structure and can replace an existing four-bar mechanism to achieve the purpose of driving the upper guide wheel to guide the chain to move to the target chain wheel.

    本发明提出了一种自行车电子后变速器及自行车,基部单元第一基部端用于连接在自行车上,其第二基部端上形成有导向部件;可移动单元第一移动端上形成有随动部件,可移动单元的第二移动端用于与链条导引单元连接;驱动单元,其驱动可移动单元靠近或远离基部单元移动的过程中,随动部件沿导向部件移动;在驱动单元驱动可移动单元靠近链轮单元的过程中,可移动单元的第二端朝向远离链轮单元的轴线的方向摆动;在驱动单元驱动可移动单元远离链轮单元的过程中,可移动单元的第二端朝向靠近链轮单元的轴线的方向摆动。本发明结构简单,能够代替现有的四连杆机构实现带动上导轮引导链条移动至目标链轮处的目的。
