A steering system may include a seat assembly, a frame assembly and a wheel. The frame assembly may include a steering tube that is rotatably disposed within a head tube with a cam at a top end and a pair of forks at a bottom end to which is coupled an axle of the wheel. An arm may be disposed on and rotatably coupled to the seat assembly, and rotatably coupled to a left armrest and right armrest. A steering rod may be coupled to the cam and to one of the arms, the left armrest or the right armrest, such that forward movement of one of the armrests causes the steering rod to be translated forward and the cam to rotate in one direction, and backward movement of the same armrest causes the steering rod to be translated backward and the cam to rotate in an opposite direction.

An operating device for a human-powered vehicle comprises a base member and an operating member. The base member extends in a longitudinal direction. The base member includes a first end portion and a second end portion. The second end portion includes a cover portion provided on a reverse side of the first end portion in the longitudinal direction. The operating member includes an outer surface configured to face away from the first end portion in a rest state where the operating member is in a rest position. The cover portion is configured to be arranged on a pivotal movement track of the operating member so as to at least partly overlap with the outer surface of the operating member in the rest state as viewed in the longitudinal direction.

The invention relates to a Seated Collapsible Vehicle. The user can fold it and carry it as a trolley whenever needed and can be used as a vehicle by unfolding it. The vehicle can be powered by an external source like motor or an engine or by human power. The vehicle comprises of a front armature connected to the rear armature by a hinge. The rear armature also comprises retractable fork for the rear wheel. The rear armature also comprises the saddle armature, mounted over a hinge. The saddle armature mounts saddle with the help of saddle mounting mechanism. Front armature comprises a encloser for battery and electronics, the foot rests are also mounted on front armature for resting legs while riding. Front fork comprises front wheel and rotatable mounted on front armature with the help of bearings. Front fork has an extension rod which mounts handlebar at other end. The extension rod can extend and retract for the purpose of folding and dragging invention like a trolley.
