    • A bicycle pedal assembly includes an axle formed integrally with a pedal body. The integral axle extends from a medial side of a pedal body through an axle connector coupled to a crank arm. The axle connector may be a separate hollow bolt screwed into a bore of the crank arm. The axle connector may house one or more bearings to facilitate rotation of the axle. The interior of the cage of the pedal body may include a variety of structures, such as bridges, or no structures, e.g., an open space, since the proximally extending integral axle need not extend across the width of the pedal body.
    • 自行车踏板组件包括与踏板本体一体形成的车轴。 整体轴从踏板本体的内侧延伸通过连接到曲柄臂的轴连接器。 轴连接器可以是螺纹连接到曲柄臂的孔中的单独的中空螺栓。 轴连接器可以容纳一个或多个轴承以便于轴的旋转。 踏板本体的保持架的内部可以包括各种结构,例如桥,或者没有结构,例如开放空间,因为近端延伸的整体轴不需要延伸穿过踏板本体的宽度。

    • A bicycle pedal assembly includes a channel-free pedal body having cross members which define holes for receiving an axle rod. The holes are axially aligned and formed with a shape which conforms to a profile of the axle rod to rotationally fix the pedal body to the rod. A first hollow bolt includes an externally threaded portion to mate with a left crank arm. A second hollow bolt includes a reversed externally threaded portion to mate with a right crank arm. Each of a pair of identical axles may be joined to either the first or second hollow bolt. Each pedal assembly in interchangeable between the left and right crank arms.
    • 自行车踏板组件包括无通道踏板本体,其具有限定用于接收轴杆的孔的横向构件。 孔被轴向对准并且形成有符合轴杆的轮廓以将踏板本体旋转地固定到杆的形状。 第一中空螺栓包括与左曲柄臂配合的外螺纹部分。 第二中空螺栓包括与右曲柄臂配合的反向外螺纹部分。 一对相同的轴中的每一个可以连接到第一或第二中空螺栓。 每个踏板组件可在左右曲柄臂之间互换。

    • A bicycle tire provides a first sidewall and a second sidewall each including an interior portion and an exterior portion. A rim attaching portion including a slipping reduction portion having an extended rim contact surface is connected to an inner circumference of each of the first sidewall and the second sidewall. A tire tread portion is connected to an outer circumference of the first sidewall and the second sidewall. A portion of the first sidewall and the second sidewall proximate to the inner circumference of the first sidewall and the second sidewall on the opposite side of the rim attaching portion from the slipping reduction portion has additional material providing a varying thickness.
    • 自行车轮胎提供第一侧壁和第二侧壁,每个侧壁包括内部部分和外部部分。 包括具有延伸的边缘接触表面的滑动减小部分的边缘附接部分连接到第一侧壁和第二侧壁中的每一个的内周。 轮胎胎面部连接到第一侧壁和第二侧壁的外周。 靠近第一侧壁的内圆周的第一侧壁和第二侧壁的一部分与边缘附接部分与滑动减小部分相反的一侧上的第二侧壁具有提供变化的厚度的附加材料。
