PROBLEM TO BE SOLVED: To provide a bicycle constructed to be light in weight and small in size and used for safe practicing for riding a one wheel vehicle. SOLUTION: In a bicycle having a front wheel 1 and a rear wheel 2, the rear wheel 2 is pivotally supported in the lower end of a seat pillar body 3 having a saddle 4 in an upper end and a pedal 6 is attached to the shaft 5 of the rear wheel 2. The rear wheel 2 is directly rotating by pressing the pedal 6 and thus the conventional necessity of providing a power transmission mechanism such as a chain wheel or a chain is eliminated. Also, the structure of the rear side of the bicycle is like that of a one wheel vehicle and this bicycle is used feeling as if riding a one wheel vehicle. |
