During my six-month exchange at the Université de Montréal, I was asked to create an electric assisted folding bicycle. My aim for this project was to avoid the usual strange-looking small wheels. My bicycle should have the proportions of a race bicycle and fit in a car trunk. That is why I designed a swivelling system that makes the rear wheel retract in the saddle. The front fork swivel on to axes to take as least space as possible. The frame is made with gel-coated carbon-fiber. The cyclist pedal movement recharges a Li-Po battery pack that transmit power to the rear wheel. The speed of pedalling determines the motor’s rpm. With this system no chain or derailleur are needed.
