    Bottom bracket based gearbox

Overview
Freeflow sourced a unique combination of motor and gearbox that allowed for a compact, efficient and powerful electric bike design. My role was to integrate this system into a bike, most significantly a mechanical engineering exercise to design a complex gearbox assembly that could fit inside an expanded bottom bracket. The innovative element of the design, is how the gearbox separates the pedal drive and motor drive while utilising the same drive train. This is a unique system amongst electric bikes that makes riding much more intuitive and easy for the rider. This design has been internationally patented. The project was taken from conception to a working prototype, the prototype is still being ridden around the Glasgow streets today. More to come soon...
