The present invention relates to a foldable electric bicycle and, more specifically, to a foldable electric bicycle which can be stably folded. The foldable electric bicycle comprises: a first body unit (100) including an upper frame (110), a steering unit (120) installed through the front of the upper frame (110), and a front wheel unit (130) supported on the lower side of the steering unit (120); a second body unit (200) including a lower frame (210) provided on the lower side of the upper frame (110), a foot support unit (220) provided on the lower frame (210), and a rear wheel unit (230) coupled to the back of the lower frame (210); a folding rotation unit (300) provided between the upper frame (110) and the lower frame (210) to fold the first body unit (100) and the second body unit (200) through relative rotation; and a seat unit (400) penetrating the upper frame (110) to interfere with the second body unit (200) to fix relative rotation between the first body unit (100) and the second body unit (200).

    본 발명은 접이식 전기자전거에 관한 것으로서, 보다 상세하게는 안정적으로 폴딩이 가능한 접이식 전기자전거에 관한 것이다. 본 발명은, 상부프레임(110)과, 상기 상부프레임(110)의 전방을 관통하여 설치되는 조향부(120)와, 상기 조향부(120)의 하측에 지지되는 전륜부(130)를 포함하는 제1바디부(100)와; 상기 상부프레임(110)의 하측에 구비되는 하부프레임(210)과, 상기 하부프레임(210)에 구비되는 발받침부(220)와, 상기 하부프레임(210)의 후방에 결합되는 후륜부(230)를 포함하는 제2바디부(200)와; 상기 제1바디부(100)와 상기 제2바디부(200)가 상대회전을 통해 폴딩되도록, 상기 상부프레임(110)과 상기 하부프레임(210) 사이에 구비되는 폴딩회전부(300)와; 상기 상부프레임(110)을 관통하여 상기 제2바디부(200)와 간섭하여 상기 제1바디부(100)와 상기 제2바디부(200) 사이의 상대회전을 고정하는 시트부(400)를 포함하는 접이식 전기자전거를 개시한다.
