PURPOSE: To provide an assist bicycle which is very compact in a folding state, can drive in a stable state and facilitate folding work.CONSTITUTION: An assist bicycle includes: a central diagonal column 3; a front column A connected by the central diagonal column 3, a pivot connection part Js and a detachable connection part Jt; a detachable operation lever 25 performing connection and disconnection of the detachable connection part Jt between the central diagonal column 3 and a front column support tool 2; a handle 8 fitted onto a front shaft 1 of the front column A and journaled with a small front wheel 71; a rear fork 34 journaled with a small rear wheel 72; and a rear column B with a saddle 91 put into a state of being fixed at an erected position and an inclined position at a middle portion of the central diagonal column 3. At the time of folding operation, by lifting up the rear column B fixed in a state of being inclined to the front side relative to the central diagonal column 3, the central diagonal column 3 and the rear column B are put into a V-shaped folded state and the central diagonal column 3 and the front column A are folded in a reversed V-shaped shape to be put into a folded state.SELECTED DRAWING: Figure 1
【目的】折り畳み状態が極めてコンパクトで、安定した状態で運転することができ、折り畳み作業を簡単にできるアシスト自転車である。【構成】中央斜め支柱3と、中央斜め支柱3と枢支連結部Jsと脱着連結部Jtとで連結された前支柱Aと、中央斜め支柱3と前支柱支持具2との脱着連結部Jtの連結及び切り離しを行う脱着操作レバー25と、前支柱Aの前軸部1に装着されると共に小型前輪71が軸支されたハンドル8と、小型後輪72が軸支されたリアフォーク34と、中央斜め支柱3の中間箇所に起立状態と倒れ状態の位置にて固定状態とされるサドル91を有する後支柱Bとが備えられる。折り畳み動作時には、中央斜め支柱3に対して前方側に倒れ状態に固定された後支柱Bが上方に持ち上げられることにより、中央斜め支柱3と後支柱BとはV字状の折り畳み状態となり、中央斜め支柱3と前支柱Aとは逆V字状に折り曲げられて折り畳み状態となること。【選択図】 図1
