Introduced by Nu Cycle, a groundbreaking change in biking is facilitated through its chainless design. This research explores the enhancement of biking through reduced maintenance needs, improved efficiency, and an eco-friendlier option. The technical aspects, materials used, and user experiences are delved into. Unlike a standard bike where you pedal in a circular motion, the Nu Cycle utilizes vertical levers instead of cranks. This allows for a straighter leg movement, reducing stress on the knees, hips, and ankles. The Nu Cycle’s levers are longer than traditional cranks, which translates to increased torque with each push. This translates to more power with less effort. The vertical pedaling motion also allows gravity to play a bigger role in propelling the bike forward. With a traditional pedal stroke, there’s a point where you’re pushing against gravity on the upstroke. The Nu Cycle’s design eliminates this wasted effort Nu Cycle transforms the way we ride, contributing to a sustainable future with its environmental considerations. Through market analysis, keywords such as potential audience, standing among competitors, challenges faced, and recommendations for future development are identified. The findings provide valuable insights into the revolutionary bicycle technology presented by Nu Cycle. Invented as a transformative alternative to standard bicycle designs, the crankshaft mechanism introduces a novel approach to force and torque generation. By replacing the traditional pedal arrangement with a modified crankshaft system, cyclists can harness a broader spectrum of muscle groups, thereby optimizing power output and mitigating muscular fatigue. the crankshaft mechanism features a redesigned crankshaft configuration that facilitates a more ergonomic and effective pedaling motion. This innovative design redistributes the workload across multiple muscle groups, promoting a balanced and sustainable cycling technique. Through a combination of pushing and pulling motions, the mechanism engages key muscle groups such as the quadriceps, hamstrings, glutes, calves, and core, resulting in improved performance and reduced risk of overuse injuries. Torque generation refers to the production of rotational force around an axis, typically within a mechanical system. In the context of cycling and the crankshaft mechanism, torque generation occurs when force is applied to the pedals, causing the crankshaft to rotate and propel the bicycle forward. The torque generated by the cyclist’s pedaling efforts depends on various factors, including the force applied to the pedals, the length of the crank arms, and the mechanical advantage provided by the gearing system. The crankshaft mechanism is designed to optimize torque generation by efficiently transferring the cyclist’s pedaling force into rotational motion. By maximizing torque generation, the crankshaft mechanism enhances the bicycle’s performance, allowing cyclists to achieve higher speeds and overcome resistance more effectively. Additionally, the distribution of torque throughout the pedaling motion can influence muscle engagement and efficiency, contributing to a smoother and more balanced riding experience.
