I think you all know about a 'Circus Cycle', a single wheel cycle that has pedals attached to the wheel itself. It moves without a chain. Young designers tried the same concept to a big wheeled bicycle with little modifications. Thats it!! We got a brand new bicycle design that runs without a chain!! Incredible isn't it? Actually this design is purely based on fiber material and doesn't require any spare parts that are existing right now.
It's just a design now but will hit the markets very soon. It is a revolutionary product that may change the coarse of cycling in the future.
Designers: Sanghyun Jeong and Jun-Tae Park.
