The present invention relates to a bicycle, the front and back wheels of which are fitted into a collapsible frame. In the folded or collapsed state, the bicycle length dimensions are reduced as compared with the working state, the back wheel is unilaterally fitted into the frame, and the front wheel is unilaterally fitted to the handlebar holding tube which is rotatably mounted on the frame. The bicycle has two wheels with different diameters, an already well-known design, wherein the front wheel with the smaller diameter is covered, in the collapsed state, by the wheel with the larger diameter, so that the smaller wheel is embedded into the larger one. In the collapsed state, the bicycle thickness may be significantly reduced.
