FIELD: mechanical engineering.
SUBSTANCE: invention relates to mechanical engineering, in particular to folding bicycles. The bicycle contains a front wheel, a rear wheel, a handlebar, a main frame, a support frame, a pedal mechanism, a first safety clip and a second safety clip. The front wheel is connected to the steering wheel. The pedal mechanism is connected to the rear wheel by means of a chain to drive the rear wheel into rotation. A saddle is provided at one end of the support frame, its other end is connected to the pedal mechanism. The second rotation axis is located between the through hole and the position where the main frame is connected to the handlebar, so that the main frame can be bent along the second rotation axis to bring the front wheel and the rear wheel closer to each other. The second safety clip is configured to secure the main frame in an unbent state.
EFFECT: increase in the portability of the bicycle is achieved.
