The utility model relates to the field of machinery, and discloses a deformable bicycle. A bicycle seat tube 3 can rotate forwards and rearwards and realize multilevel position adjustment ( a bicycle rear fork 5, namely a connecting tube between the seat tube 3 and a circle center axle of a rear wheel can freely stretch and retract), a bicycle front fork 4 can rotate forwards and rearwards and realize multilevel position adjustment (a front connecting tube 1, namely a connecting tube between the bicycle front fork 4 and a lower tube 2 can freely stretch and retract), the connecting tube 1, the lower tube 2 and the seat tube 3 are crossed at a concentric round shaft, the seat tube 3 can rotate around the concentric round shaft, and the bicycle front fork 4 can rotate around a front wheel axle (the front connecting tube 1 and the lower tube 2 are fixed structures connected together). Riding postures of a rider can be changed freely, muscle fatigue due to the fact that the rider keeps the same posture during lon
