PROBLEM TO BE SOLVED: To provide a two-wheeled bicycle that improves hill-climbing performance by bringing about erratic driving of a drive wheel itself concurrently with rotary drive by a pedal.SOLUTION: A front part is provided with a steering wheel 1 with a handle 4; a rear part is provided with a drive shaft 8; and a force for depressing a pedal 6 is transferred to a rear wheel. The rear wheel is provided with a rotating shaft 13 in a vertical direction from a ground surface. Thus, the rear wheel is shaken from side to side with respect to a traveling direction depending on the force for depressing the pedal so that erratic driving can be performed. The execution of the erratic driving can reduce an apparent inclination of a slope during slope climbing to improve slope climbing performance.SELECTED DRAWING: Figure 1

    【課題】ペダルによる回転駆動と同時に駆動輪自体を蛇行運転させることで登坂性能を向上させる二輪の自転車を提供する。【解決手段】前部にハンドル4付きの舵取輪1を備え後部に駆動軸8を備えペダル6を踏む力を後輪に伝え回転駆動する二輪の自転車において、後輪に地面から縦方向に回転軸13を設けた。これによりペダルを踏む力に応じて後輪が進行方向に対して左右に振れ蛇行運転をする。蛇行運転することで登坂時に坂の見かけの勾配を低減でき登坂性能を向上させることができる。【選択図】図1
