本新創增力曲柄乃藉由曲柄主體之內設一組同步齒輪再連接一組特殊高效能的弧形加力桿，如此連動機械結構於曲柄主體連動時經由同步齒輪之相對運動使加力桿頂端與曲柄主體構成「平行連桿」作動原理，因此加力桿會永遠維持水平方位進行順暢的圓周運動。於此同時加力桿的功能已有效的大幅增加整體0度至180度之施力臂長度，對比傳統自行車之曲柄不但大幅提升馬力且更加平順，使得騎乘舒適度得到很大的改善。
本新型增力曲柄百分之百完全繼承傳統自行車曲柄的驅動模式及完全同樣的人體工學原理，雙腿以循環式圓周運動持續運轉且更輕鬆地作動並增加出很巨大的動力。開發業界首創自行車之可增力踩踏曲柄裝置，包括曲柄機構、齒輪、傳動軸及增力旋臂。使用現有的自行車進行改裝，比對測試可增力達50%以上。加大施力臂之有效作功長度來增加力矩，其中所增進的扭力(扭力x轉速=馬力)即增踩踏馬力，不僅結構簡單且傳動穩定確實。
加力桿之外形充滿美感，與各種車型又可有長短之設計。如之於公路車或登山車其長度有所別，因於前輪與加力桿之安全距離尺寸。故加力桿之造型可因長度而有所不同的造型與可創作出之差異美感及其價值。
本產品為全球獨創之自行車動力設計，機械結構簡潔有力及輕巧具美感，並能使尋常自行車抗空阻更強、騎得更快、騎得更遠、爬得更高以及可讓雙膝更舒適健康。
Operating principles and functions
This new power-increasing crank has a set of synchronized gears inside the crank body and is connected to a set of special high-efficiency arc-shaped intensifier rods. In this way, the linked mechanical structure makes the top of the intensifier rod and the crank body form a “parallel connecting rod” operating principle through the relative movement of the synchronized gears when the crank body is linked. Therefore, the intensifier rod will always maintain a horizontal orientation and perform smooth circular motion. At the same time, the function of the booster bar has effectively greatly increased the overall length of the force arm from 0 degrees to 180 degrees. Compared with the traditional bicycle crank, it not only greatly increases the horsepower but is also smoother, greatly improving the riding comfort.
This new type of power-increasing crank completely inherits the driving mode of the traditional bicycle crank and the same ergonomic principle. The legs continue to operate in a cyclic circular motion and act more easily, adding a huge amount of power. Developed the industry’s first bicycle power-increasing pedaling crank device, including crank mechanism, gears, transmission shaft and power-increasing arm.
Using existing bicycles for modification, comparison tests can increase power by more than 50%. The effective working length of the force-applying arm is increased to increase the torque. The increased torque (torque x speed = horsepower) is the increase in pedaling horsepower. It is not only simple in structure, but also stable and reliable in transmission.
The appearance of the booster rod is full of beauty, and it can be designed in different lengths to match various car models. For road bikes or mountain bikes, the length is different due to the safety distance between the front wheel and the booster bar. Therefore, the shape of the intensifier rod can be different depending on the length, and can create different aesthetics and values.
This product is the world’s original bicycle power design. The mechanical structure is simple, powerful, lightweight and aesthetically pleasing. It can make the bicycle more resistant to air resistance, ride faster, ride further, climb higher, and make the knees more comfortable and healthy.
