To provide a deformation bicycle capable of changing an interval between front and rear wheels so as to be usable by an adult and a child.
A deformation bicycle 1 includes a shaft-shaped frame base 7 extending in the width direction of the bicycle, a pair of frame extension parts extending in a horizontal direction from both ends of the frame base 7, a pair of front wheel units 3 fitted to the pair of frame extension parts at positions different from the frame base 7 in the horizontal direction, a shaft-shaped main frame 9 connected to the frame base 7 to be rotatable around a base rotational axis 7X and a main rotational axis 9X orthogonal to the axis 7X, and a holder for holding the main frame at predetermined rotational positions around the base rotational axis 7X and the main rotational axis 9X. The front-and-rear wheel interval L2 of a child bicycle where the main frame 9 is located on the front wheel unit 3 side is shorter than that of a basic form where the main frame 9 is located on a side opposite the front wheel unit 3.
