Orbea Optima E50 Electric Bike (E-BIKE)

Optima is an apparently “normal” bicycle, but both the architecture and the ergonomics of the new Optima are innovative. It is a bike designed to be used as an electric bicycle from the conceptual design phase. This has meant revamping the product to the point that even its architecture changed.
