The invention pertains to a bicycle with variable wheelbase which converts the user's body expansion and contraction into propulsion. The invention comprises a frame [1] having a front wheel, and a structure [2] having a rear hub [4]. The structure [2] is suspended pivotally to the frame [1] about a rotational axis [3]. The wheelbase is varied by pivoting the structure [2] about the rotational axis [3]. By pivoting the structure [2], the catching wheels [7] and [8], both connected to the rear hub [4], travel along the retainer [5] and [6], respectively, and transmit torque to the rear hub [4] in one direction.
