    • An adjustable exercise bicycle includes a fixed frame, a seat, a movable frame, a locking device, a pedal device and an assisting device. The assisting device is arranged between the fixed frame and the movable frame. The assisting device is for forcing the movable frame and generating a first moment about the axis. The total weight of the movable frame and its loading generate a second moment about the axis. The resultant moment of the first moment and the second moment is a third moment which can move the movable frame from a second angle to a first angle when the movable frame is oriented at an unlocked state. The user can force the pedal device against the third moment for moving the movable frame from the first angle to the second angle.
    • 可调节的运动自行车包括固定框架,座椅,可移动框架,锁定装置,踏板装置和辅助装置。 辅助装置设置在固定框架和可动框架之间。 辅助装置用于迫使可动框架并围绕轴线产生第一时刻。 可移动框架的总重量及其负载围绕轴线产生第二个力矩。 第一时刻和第二时刻的合成时刻是第三时刻,当可移动框架被定位在解锁状态时,可以将可动框架从第二角度移动到第一角度。 用户可以迫使踏板装置抵抗第三时刻,以将可移动框架从第一角度移动到第二角度。
