The drivetrain of most modern bicycles has remained relatively unchanged for nearly a century. There have been marginal upgrades here and there like electronic shifting but you'll still mostl
The article from Hackaday, dated May 15, 2025, discusses an innovative project that introduces an automatic transmission system designed for manual transportation devices, such as bicycles and rickshaws. This system aims to reduce the physical effort required by users, making these modes of transport more accessible and efficient. The automatic transmission is engineered to seamlessly shift gears based on the speed and load, enhancing the user experience without the need for manual gear changes. The project highlights the potential for such technology to revolutionize urban mobility, particularly in developing regions where manual transport is prevalent. The article also includes insights from the developers on the challenges faced during the design and testing phases, as well as future possibilities for integrating this technology into other types of vehicles.
