Patent ID: 8602436

Claim:
A foldable bicycle, comprising: at least one first frame part that supports a front wheel of the bicycle and a second frame part that supports a rear wheel of the bicycle, said first frame part and said second frame part being joined together by a joint having one single geometrical rotation axis, said geometrical rotation axis being tilted with respect to a direction perpendicular to a longitudinal plane of the bicycle, so that, by means of a relative rotation of said first frame part and said second frame part with respect to each other around said geometrical rotation axis, the bicycle moves from an unfolded position, wherein said front wheel is aligned with said rear wheel in the longitudinal plane of the bicycle, to a folded position wherein said front wheel lies next to said rear wheel in a different plane; a handle which is pulled upwards to produce a movement from the unfolded position to the folded position of the bicycle via an actual weight of the bicycle and the relative rotation of said first frame part and said second frame part around said geometrical rotation axis, said joint being an annular joint, in a shape of a ring that delimits an inner free space that is wide enough to receive a hand of an adult across a whole width of fingers with an exception of a thumb, so that said annular joint constitutes said handle.
