Chainless Bicycle Prototype The Q
The Q is known for his crazy inventions, like this hubless bicycle, and his latest project is definitely no slouch either. He decided to build a chainless bicycle that can still be ridden normally, without any extra accessories or parts. Typically, a bicycle chain transfers the driving power from the bike’s pedals to its rear wheel for propulsion. Read more to see how this chainless version works.



This isn’t the first chainless bicycle, as there are many shaft-driven versions out there. For those who don’t know, these bicycles use the drive shaft instead of a chain to transmit power from the pedals to the wheel. In other words, it sports a large bevel gear where a conventional bike would have its chain ring. This then meshes with another bevel gear mounted on the drive shaft, thus allowing the axis of the drive torque from the pedals to be turned through 90°.
