    • A three-wheeled device (10) for pedal-powered riding, wherein the device (10) provides a substantial but not excessive riding challenge. The preferred device (10) broadly comprises three wheels (12); two shafts (14); and two pedals (16). The wheels (12) are oriented parallel to one another so as to rotate about a common axis. Each shaft extends between and couples (14) two of the wheels (12) in an offset manner. Bearings (26) may be provided to facilitate movement of the shafts relative to the wheels (12) by reducing friction therebetween. Each pedal (16) is coupled with a different one of the shafts (14). For added safety, the pedals (16) may include non-slip contact surfaces (30) and light reflectors (32). In use, a rider stands on the pedals (16) and applies force thereto, with the force being transferred via the shafts (14) to the wheels (12) which are thereby caused to roll.
    • 一种用于踏板动力骑行的三轮装置(10),其中所述装置(10)提供实质但不是过度的骑乘挑战。 优选的装置(10)广泛地包括三个轮(12); 两个轴(14); 和两个踏板(16)。 轮(12)彼此平行定向以便围绕公共轴线旋转。 每个轴以偏移的方式在两个轮(12)之间延伸并联接(14)两个轮(12)。 可以设置轴承(26)以便于通过减小轴之间的摩擦来相对于车轮(12)的运动。 每个踏板(16)与不同的一个轴(14)联接。 为了增加安全性,踏板(16)可以包括防滑接触表面(30)和光反射器(32)。 在使用中,骑车人站立在踏板(16)上并施加力,其中力通过轴(14)传递到由此引起滚动的轮(12)。
