    • A two-purpose-pedal consists of a shaft or spindle adopted to attach to a crank-arm using one longitudinal side, a pedal body rotatably attached to the other longitudinal side of said pedal shaft, and two parallel straight holes on said pedal body sandwich said pedal shaft in the middle. Each of the said two parallel straight holes is designed to tightly fit the base of a particular instep-coupler and can be disjoined by space in between. Said two straight holes can either parallel to or perpendicular to said pedal shaft. The former require the two holes be entered from the back side of said pedal body and exit with flat surface surround the end of holes, said flat surfaces are perpendicular to the direction of the holes. The latter required the two holes located near the back side of said pedal body with flat surfaces surrounding both ends of the holes, said flat surfaces are perpendicular to the direction of the hole.
    • 一个双用途踏板包括一个轴或主轴,用于使用一个纵向侧连接到一个曲柄臂,一个可旋转地连接到所述踏板轴的另一纵向侧的踏板体,以及在所述踏板本体夹层上的两个平行的直孔 所说的踏板轴在中间。 所述两个平行的直孔中的每一个被设计成紧密地配合特定的脚背耦合器的基部,并且可以被间隔开。 所述两个直孔可以平行于或垂直于所述踏板轴。 前者需要从所述踏板本体的后侧进入两个孔,并且围绕孔的端部以平坦的表面离开,所述平坦表面垂直于孔的方向。 后者需要位于所述踏板体的后侧附近的两个孔,其平坦表面围绕孔的两端,所述平坦表面垂直于孔的方向。
