摘要： A Tread Wheel Frame System drives a human-powered cycle by a tread wheel driving a tread of a drive wheel of a cycle rather than driving a drive wheel hub, as conventional cycles do. Most of the driving mechanism, including the tread wheel, a speed ratio mechanism, shifting device, and a power unit device, are safely located above the level of a cycle's axles where they are less likely to encounter accidental impact. The tread wheel with the power unit device also does the braking, which eliminates the need for caliper brakes or hub brakes. Accordingly, a drive wheel is lighter, without the need for a heavy hub, or a heavy rim to withstand the wear and heat of friction of caliper brakes. The tread wheel frame is uniquely designed and engineered to be light, yet strong where needed. The best mode includes many features: an energy recapture and storage system that saves energy that would be lost in braking, for assisting in going up hills, thigh levers, extendable pedal cranks for providing more pedal leverage, a frame extension that has no cross bar, and foot room to allow easy, low-level, mounting and dismounting, retractable stand, lean-on device, adjustable steering, and low-mass suspension.
摘要翻译：踏步车轮系统通过轮胎驱动人力循环，驱动轮胎的驱动轮的胎面而不是驱动驱动轮毂，如常规循环。大多数驱动机构，包括踏板轮，速比机构，变速装置和动力单元装置，都安全地位于循环轴的水平面上，在这些轴的水平处不太可能遇到意外的冲击。具有动力单元装置的踏板轮也进行制动，这消除了对卡钳制动器或轮毂制动器的需要。因此，驱动轮较轻，不需要重型轮毂或重的轮辋来承受卡钳制动器的摩擦磨损和热量。胎面轮框架设计独特，设计轻巧，坚固耐用。最好的模式包括许多功能：能量回收和储存系统，可以节省在制动中丢失的能量，帮助上坡，大腿杠杆，可伸缩的踏板曲柄，提供更多的踏板杠杆，不带横杆的框架延伸，以及足部房间，可以方便，低级，安装和拆卸，伸缩式支架，精密设备，可调节转向和低质量悬挂。
