The invention relates to a foldable bicycle, compact when folded, facilitating storage or transport. It comprises a rear part supporting a rear wheel 23 along a rear rotation axis, a front part supporting a front wheel 24 along a front rotation axis parallel to the rear rotation axis, and a crankset 12 mounted between the front and rear parts. rear and connected to the rear wheel by a chain 13 to drive it in rotation The bicycle shifts from a position of use with the two axes of rotation spaced a first distance apart, to a stowed position with the two axes of rotation spaced a second distance less than the first. Folding means allow the rear wheel to move from the position of use to the folded position by translation of its axis of rotation towards the crankset. Figure for the abstract: 1A
