Bicycles have not evolved much since their birth in the 18th century. Especially the transmission system, which still relies on ancestral chain transmission, is true that the efficiency is not high.
However, at this year’s Eurobike exhibition in Germany, a company launched a disruptive bicycle called Cdriven.
Just looking at the appearance makes me so handsome that I can’t close my legs. It’s full of technology. The introduction makes me unable to walk. The transmission efficiency is as high as 99%, claimed to be the most labor-saving bicycle in the world!
Looking carefully, Cdriven is indeed different from ordinary bicycles. The ancestral chain device is gone, replaced by a unique geared shaft drive system: a carbon fiber shaft connects the front single chainring to the rear 13-speed flywheel.
The specific transmission principle is this: when you step on the pedals, the chainring will rotate; then the chainring meshes with the bearing on the carbon fiber shaft, so that The carbon fiber shaft also rotates; then the carbon fiber shaft drives the rear 13-speed flywheel in the same way, and finally the rear wheel starts to rotate.
It’s a convoluted explanation, but you should look at the pictureI can figure it out~ So how awesome is this chainless transmission system? Look, the wheel can spin 6 times once you pedal it! It can also perform 13-level shifting, making it easy to ride the ten-mile Yangzhou Road in the spring breeze.
Of course, the 99% transmission efficiency cannot be blown out. On the one hand, compared with ordinary chain transmission, this shaft transmission system does not exist due to chain articulation. Friction caused;
On the other hand, it also uses 21 exclusively customized ceramic bearings to further reduce friction during meshing;
The company claims that the force exerted by the driver can be almost completely converted into driving force. With the same amount of force pedaling, this bicycle can perform better than bicycles with chains. Go faster and further.
In addition, it does not lose efficiency due to chain wear, so its lifespan is longer than that of ordinary bicycles.
Due to its disruptive design, Cdriven won the 2018 Eurobike Award in the past few months, which can be regarded as proving its strength.< /p>
But the price is also very subversive... A car worth 100,000 yuan is not something you can buy if you want. Whenever I see this kind of thing, I feel a bit... For products with sky-high prices, I hope that China’s copycat industry will become more developed. I believe that one day, Huaqiangbei will offer 1,000 yuan to make it disgusting!
