Folding vehicle

A folding vehicle comprising:

• a front frame, the front frame including:
• an upper end to which a handle is attached;
• and
• a lower end to which a front wheel is attached;
• a based frame by which the front frame is pivotally supported;
• a main frame mechanism, the main frame mechanism including:
• a first frame member pivotally supported with respect to the base frame;
• and
• a second frame member arranged in parallel with the first frame member,
• wherein the first frame member and the second frame member form a parallel link mechanism;
• a board attached to the main frame mechanism;
• a saddle member attached to at least one of an upper end portion of the first frame member and an upper end portion of the second frame member of the main frame mechanism;
• and
• a swing arm, the swing arm including:
• one end pivotally supported by the main frame mechanism;
• and
• another end by which a pair of rear wheels are rotatably supported,
• wherein the folding vehicle is switchable among:
• a first mode, in which the main frame mechanism is folded, achieved by pivoting the main frame mechanism toward the front frame;
• a second mode, in which driving while being seated on the saddle member is enabled, achieved by pivoting the main frame mechanism in the first mode;
• and
• a third mode, in which driving while standing on the board is enabled, achieved by pivoting the main frame mechanism in the second mode, and
• wherein the saddle member remains to be in a state of being attached to at least one of the upper end portion of the first frame member and the upper end portion of the second frame member in the first mode, the second mode, and the third mode.
