An innovative drivetrain solution that completely eliminates the limitations of traditional chains and structural layouts. Ideally suited for cargo bikes and tandem configurations, it supports pedal-powered energy generation, cadence sensing, and resistance simulation—enabling a cleaner and more flexible integration of electric drive systems.

This pedal-assist range extender system breaks free from the geometric constraints of mechanical transmission by employing an intuitive speed control algorithm. During riding, cadence and pedaling energy are captured and transmitted to the motor, delivering a smooth and highly responsive experience. A network of sensors continuously collects and analyzes riding data such as slope and wind speed, automatically adjusting pedal resistance to create a natural pedaling feel.

Notably, the built-in generator efficiently recovers and transfers pedaling energy to the motor, extending range and promoting energy efficiency. Additionally, users can switch between various riding modes and flexibly adjust power generation settings to meet individual preferences—enhancing both sustainability and personalized performance.
