    • A tricycle convertible to a bicycle. The tricycle has a first wheel rotatably mounted on one end portion of a frame, and a pair of laterally spaced wheels rotatably mounted on a second end portion of the frame, wherein the laterally spaced wheels are movable, while the tricycle is in motion, between a first position with relatively wide ground-level spacing and a second position with minimal ground-level spacing. A wheel hub capable of providing adjustable wheel camber has left and right pivotally mounted axles extending laterally from the hub body, the axles each adapted to support a wheel and mounted so as to pivot vertically, and a dual camber control mechanism coupled to the axles and adapted to provide coordinated camber adjustment in the same direction for wheels on both axles. The hub has sufficient range of motion to allow the wheels to change from negative camber to positive camber, and is useful in a method of stabilizing a bicycle or the like to increase safety during rider training. The method involves a tricycle mode of operation in which the laterally spaced wheels have negative camber, and a bicycle mode of operation in which the laterally spaced wheels have positive camber, with a change from tricycle mode to bicycle mode while in motion, whereby a rider in training may start moving with stable three-point ground contact and, when in motion and balanced, effectively start riding a bicycle.
    • 一辆可转换成自行车的三轮车。 三轮车具有可​​旋转地安装在框架的一个端部上的第一轮和可旋转地安装在框架的第二端部上的一对侧向间隔开的车轮,其中横向隔开的车轮可移动,同时三轮车在运动中, 具有相对较宽的地面间距的第一位置和具有最小地面间距的第二位置。 能够提供可调节轮轮的轮毂具有从轮毂本体横向延伸的左右枢转安装的轴,所述轴各自适于支撑车轮并安装成垂直地枢转,以及联接到所述车轴的双外倾控制机构, 适用于为两轴上的车轮提供相同方向的协调外倾调整。 轮毂具有足够的运动范围,以允许车轮从负弧度变化到正弯度,并且在用于稳定自行车等的方法中有用以提高驾驶员训练期间的安全性。 该方法涉及三轮车操作模式,其中横向间隔开的车轮具有负弯道,以及自行车操作模式,其中横向间隔开的车轮具有正弯度,在运动中从三轮车模式改变为自行车模式,由此骑手 在训练中可能会开始稳定的三点地面接触,当运动平衡时,有效开始骑自行车。
