Folding type electric bicycles

A folding electric bicycle comprising:

• a first body unit comprising a first frame having a guide hole passing through at least a portion of a side surface of the first frame, the first body unit further comprising a steering part passing through a front portion of the first frame, and a front wheel part supported by a lower side of the steering part;
• a second body unit comprising a second frame connected to the first frame, a pedal part disposed on the second frame, and a rear wheel part coupled to a rear portion of the second frame;
• a movement unit passing through the guide hole to linearly move and coupled to the second frame to linearly move along the guide hole so that the second body unit moves relatively to the first body unit;
• and
• a fixing unit installed on the first frame to restrict a linear movement of the movement unit,
• wherein the movement unit comprises:
• a hinge shaft part passing through the guide hole and connected with the second frame;
• and
• a pair of guide blocks extending from ends of the hinge shaft part in a radial direction of the hinge shaft part and disposed adjacent to the first frame, and
• wherein the fixing unit comprises:
• a fixing hinge shaft passing through the first frame;
• an interference part configured to implement and release interference with the movement unit through a hinge-rotation at ends of the fixing hinge shaft;
• and
• a coupling pin coupled to a coupling groove defined in the first frame in order to fix the interference part.
