To provide an electric three-wheeled bicycle that can be changed to electric motor control when pushing the bicycle by a simple operation.SOLUTION: The problem is solved by the electric three-wheeled bicycle including a protruding conductive rubber protruding from a handlebar post with an insulating member sandwiched therebetween, a horizontal arm having one end connected to the handlebar post so as to be rotatable up and down and having a conductive coating applied to the area where the arm comes into contact with the conductive rubber, an auxiliary output adjustment grip provided at the end of the handlebar and rotatable forwards and backwards and increasing output when turned backwards, a rotation angle detector for detecting the rotation angle of the auxiliary output adjustment grip, and a vehicle speed sensor for detecting vehicle speed. When a control unit detects that a current has flowed through the conductive rubber and the vehicle speed sensor detects that the vehicle speed is below a predetermined vehicle speed, the control unit controls the output torque of the electric motor based on the rotation angle of the rotation angle detector to vary the push-walking speed below the predetermined speed and output the same.SELECTED DRAWING: Figure 6
【課題】簡単な操作で、押し歩き時の電動モータ制御に変えることができる電動三輪自転車を提供することを課題とする。【解決手段】ハンドルポストから絶縁部材を挟入させて突設された突起状の導電性ゴムと、ハンドルポストに上下方向に回動自在に一端部を連結された、導電性ゴムとの当接範囲に導電性被膜が被覆された横アームと、ハンドルバーの端部に設けた、前方向及び後方向に回転可能で後方向に回すと出力増となる補助出力調整グリップと、補助出力調整グリップの回転角を検出する回転角検出器と、車速を検出する車速センサとを備え、制御部が、導電性ゴムに電流が流れたことを検知し、車速センサが所定の車速以下であることを検出したときに、回転角検出器の回転角に基づいて電動モータの出力トルクを制御して押し歩き速度を所定速度以下で可変させて出力させる電動三輪自転車により課題解決できた。【選択図】 図6
