[Problem] To provide a bicycle whose wheelbase can be changed.[Solving Means] A top tube 1011 included in a bicycle 1 consists of a front top tube 1011F that is located on the front side and a rear top tube 1011B that is located in the rear side. The rear top tube 1011B is inserted into the front top tube 1011F and is fixed to the front top tube 1011F by a length adjustment mechanism. A user is able to adjust the length in the front-rear direction of the top tube 1011 by releasing the rear top tube 1011B fixed by the length adjustment mechanism, sliding the rear top tube 1011B with respect to the front top tube 1011F in the front-rear direction, and fixing the rear top tube 1011B to the front top tube 1011F at a desired position using the length adjustment mechanism.
