Sergii Gordieiev, creator of Youtube channel “The Q,” has developed a working chainless bicycle utilizing a sequence of 3D printed plastic gears. The system consists of 1 giant gear linked to 4 smaller gears that switch rotational movement from the pedals to the rear wheel.
The gear system requires exact alignment and measurements to operate correctly. If one gear slips out of place, all the drivetrain fails to function. Gordieiev painted the initially white plastic gears orange to make them extra seen when driving the bicycle.
In his YouTube video, Gordieiev demonstrates the development course of, together with constructing the body modifications wanted to mount the gear system. He first examined the gears on a picket floor earlier than putting in them within the place usually occupied by a bicycle chain. The ultimate small gear connects on to the rear wheel’s hub, finishing the mechanical linkage.
The undertaking showcases how 3D printing can create customized bicycle elements at house. Customers can doubtlessly exchange broken gears with out visiting a motorcycle store, utilizing normal 3D printing filaments. Whereas presently solely the gears are 3D printed, the strategy may lengthen to different bicycle elements for additional customization.
