The vehicle includes a platform (2) made from two parts, a front part (10) and a rear part (11) that is movable in relation to the front part (10) between a folded position and an unfolded position. A steering column (20) includes a lower part (50) and at least one upper part (51) that can be unfolded and folded telescopically in relation to the lower part (50). A transmission (12) between the front part (10) of the platform and the upper part (51) of the steering column (20), arranged so that unfolding the rear part (11) of the platform causes the upper part (51) of the steering column (20) to unfold and, conversely.

1. A foldable two-wheel vehicle comprising: a platform to position a user, the platform includes a front part and a rear part movable in relation to the front part, said rear part being movable between a collapsed position, in which the rear part is retracted in relation to the front part, and an extended working position;a steering assembly including a steering column having a front wheel situated at the front part of the platform, the steering column having a lower part and at least one upper part that is connected telescopically relative to the lower part;a rear wheel situated at the rear part of the platform; anda transmission located between said front part of the platform and said upper part of the steering column, the transmission is arranged so that extending the rear part of the platform causes the upper part of the steering column to extend and, conversely, retracting the upper part of the steering column causes the rear part of the platform to retract. 2. The vehicle according to claim 1, wherein the rear part of the platform comprises a pivoting rear assembly on which the rear wheel of the vehicle is mounted. 3. The vehicle according to claim 2, wherein the pivoting rear assembly comprises two arms pivotably mounted on two branches secured to said rear part of the platform; the rear wheel is mounted between the two arms on rear ends of the arms, and said arms include locking extensions; said branches include a locking part slidingly mounted thereon, the branches comprising two cavities capable of receiving said locking extensions in an unfolded position of the pivoting rear assembly, said locking part being biased in a locking position by elastic means; the locking part is longitudinally movable on said branches between the locked position, in which the locking part receives said locking extensions in said cavities, thereby locking the pivoting rear assembly in the unfolded position, and a retracted position, in which the locking part frees said locking extensions of said cavities and thus does not hinder the pivoting of said arms; andthe pivoting rear assembly comprises a control member of the locking part, actuated by said transmission. 4. The vehicle according to claim 3, wherein said control member of the locking part is a pivoting cam, not pivotably connected to the arms on a first sector of a pivoting movement of the cam, and pivotably connected to said arms on a second sector of the pivoting movement, said second sector being adjacent to the first sector; the cam is configured so during the pivoting movement on said first sector, the cam moves the locking part from its locking position toward a retracted position, and, during a pivoting movement on said second sector, the cam pivots said arms. 5. The vehicle according to claim 4, wherein said transmission comprises a cable connected to said front part of the platform, a first part of the cable extends along the front part and the rear part of the platform, passes over said pivoting cam and is fixed thereto, and wherein a second part of the cable extends, from the fastening point of the cable on the cam, again along the front part and the rear part of the platform, then penetrates the steering column and is engaged on an upper pulley included by said lower part of said steering column, then is connected to a lower part of said upper part of said steering column; from the collapsed position of the vehicle, the movement of said rear part of the platform in relation to said front part of the platform toward its extended working position first exerts a pulling force on said first part of the cable, causing the cam to pivot on said first sector, then, once the cam arrives in said second sector, causes the rear pivoting assembly to pivot; once the cam arrives in said second sector, the movement of said rear part of the platform also exerts a pulling force on said second part of the cable, thereby performing the telescoping extension of the upper part of the steering column in relation to the lower part thereof. 6. The vehicle according to claim 1, further comprising a manually deployable portion on the steering column, the manually deployable portion is connected to handle bars. 7. The vehicle according to claim 1, further including handlebars having a tube perpendicularly connected to the steering column, said handlebars comprising a stationary part and a moving part, the moving part is unfolded and folded in relation to said stationary part. 8. The vehicle according to claim 1, wherein the rear part is situated in an extension of the front part.
