Haven Mercer Unveils Innovative Mechanical Automatic Transmission Concept
Inventor Haven Mercer has patented an automatic transmission system for bicycles that features a continuously variable transmission, allowing for an infinite number of gear ratios. The system is fully automatic and entirely mechanical, with the chainring and rear sprocket expanding and contracting in response to torque inputs. Mercer has created a working prototype and aims to develop the system for trail riding, with potential applications for road cycling. The transmission eliminates the need for shifting, potentially improving safety and ease of use for cyclists.
