To provide a bicycle which can be folded small, is lightened, reduces carrying burden, is always available on trip, and further, can eliminate the hassle of parking in a city area.SOLUTION: In a foldable frame of a front wheel drive bicycle that converts a force of stepping on a pedal (5) into a pulling force of a rope and drives a front wheel (100) around, a down tube (1) is anchored in a ground direction by a handle bearing part, a coupling end part of a triangular frame (2), which is folded at a rear wheel bearing and is coupled to the down tube via an auxiliary link (4) at a lower end thereof, is so made as to be attachable/detachable, and fixing means therefor is performed by a claw (9) formed at a lower part of a saddle pole (3) installed nearby. When folding, the saddle pole is knocked down to the handle side to remove the fixing means, and the auxiliary link is rotated to push down the saddle pole, whereby a rear wheel is lifted, and a saddle and the rear wheel are accommodated in an upper part of the front wheel.SELECTED DRAWING: Figure 1

    【課題】自転車を小さく折り畳め、軽くし、携帯する負担を軽減し、旅に常備でき、また市街地の駐輪の煩わしさを無くすことの可能な自転車が課題である。【解決手段】ペダル(5)の踏み込む力をロープの引き力に変え、前輪(100)を引き回し駆動する前輪駆動自転車の折り畳みフレームであって、ハンドル軸受部より地面方向にダウンチューブ(1)を固着し、その下端の補助リンク(4)を経て、後輪軸受で折り返しダウンチューブに結合する三角フレーム(2)の結合端部を着脱可能としその固定手段をその近くより設置されるサドルポール(3)下部に形成された爪(9)により行う。折りたたみ時はサドルポールをハンドル側に倒し固定手段を外し、補助リンクを回動しサドルポールを押し下げると後輪が持ち上り前輪上部にサドルと後輪が収まる。【選択図】図1
