发明名称 ARM STEPPING-IN TYPE BICYCLE
摘要 <p>PROBLEM TO BE SOLVED: To provide a foot stepping type bicycle transmittable without losing energy of foot stepping motion, in a bicycle moved by the foot stepping motion.SOLUTION: An arm stepping-in type bicycle is formed as a structure of internally installing a freewheel mechanism in a free hub body 1 and also directly extending an arm 3 from the free hub wheel 1 with the tip as a stepping-in pedal 2. Thus, pedal-stepping-in force rotates a rear wheel 10 via the free hub body 1, and when releasing force of feet, the connection of the pedal 2 and the rear wheel 10 becomes free by operation of the freewheel mechanism, and the arm 3 returns to an original stepping-in position by return force of a spring 16, and this operation is continuously executed between a right foot and a left foot, so that the bicycle can be advanced.</p>
