This Technology can change Bicycle Industry (Nubike) ...(Hindi)

Probably ever since bicycles were first invented, people have been looking for alternatives to the traditional approach of pedalling in circles. Los Angeles-based inventor Rodger Parker has utilized one such alternative in his NuBike, which he claims is more efficient than a chain-drive bike. Along with its unique-looking carbon fiber frame, what really stands out on the NuBike are the levers that run from the pedals to a linkage on the rear hub. These allow riders to simply push up and down on the pedals, causing the rear wheel to turn. There are reportedly a number of advantages to this setup. First of all, as mentioned, it’s claimed to be more efficient than a chain or belt-drive. According to Brown, because the levers are much longer than traditional cranks, riders are able to deliver more torque (and thus power) to the wheel for a given amount of effort. He also states that because the pedals just move vertically, riders can more effectively use the force of gravity to help push them do
