Abrégé
(EN) The invention provides a multifunctional four-wheel deformable bicycle which comprises a bicycle frame, two front wheels, two rear wheels, a loading base, a steering mechanism, a braking mechanism, a pedal device, a chain transmission mechanism and a seat cushion. The bicycle is characterized in that the bicycle frame comprises a bicycle frame front sleeve, a bicycle frame middle rod, a bicycle frame rear sleeve, a bicycle frame rear carriage, a bicycle frame inclined connecting pipe and a bicycle frame cross connecting pipe; the part of the bicycle frame middle rod, located in front of the bicycle frame rear sleeve, just retracts in the bicycle frame front sleeve; the plane of the loading base is provided with an embedded hidden removable flatly stacked fence; the bottom of the loading base is provided with a shock reducer; the steering mechanism comprises a horizontally connected cross rod and left and right two independent handle bars; the lower end of the upper handle bar is inserted in the upper end of the lower handle bar and is axially connected with the lower handle bar; the upper handle bar is movably connected with a rear edge connecting rod of the loading base; and the two ends of the horizontally connected cross rod are respectively axially connected to front ends of the front extending bars of the left and right two handle bars. The bicycle has the advantages that the structure is simple, manpower is saved during operation, the telescopic distance of the bicycle frame is large and the handle bars are foldable and retractable, the overall bicycle can be changed into a baby carriage and a shopping trolley.
