The Electrobike Pi is a hybrid human-electric powered bicycle. It was designed mostly for commuters who want to reduce their dependence on the automobile. The bike's frame design is patent-pending, with an ability to change the seat position to an upright or semi-recumbent, depending on the preference of the rider. The bike has 3 modes: completely electric powered, electric & pedal powered, or pedal powered only. A switch that sits atop the handlebars allows you to easily switch between the 3 options.
