We live in a world where the need for lighter, more efficient vehicles is glaringly apparent, and in recent times designers and automotive manufacturers have ramped up their efforts to meet this challenge. Given this climate it's not surprising to see the enviro-conscious "Movito" scooter design receive accolades in the Create the Future Design Contest. Engineer/Designer Tiam Chiem's Movito is a 2-modular design consisting of an upper scooter chassis and the base which provides the drive via an in-wheel electric motor and hubless front wheel. The modular design allows a range of possible morphs, including multiple bodies to be connected to the base or two bases to be connected in parallel to form a two-seater.
The in wheel motor
The use of an in-wheel motor has allowed Chiem to design the structure of the scooter for weight reduction and a dynamic shape and form. Developed by CSIRO Australia, the in-wheel motor which is currently utilized in solar powered racing cars, boasts 98% efficiency, claimed by CSIRO to be higher than any other in-wheel motor. Weighing in at only 6kgs, the direct drive eliminates drive train loss and the motor is charged by Li-ion batteries stored in the central body. Steering
The Motivo’s hubless wheel is based on the technology developed by Osmos and provides, amongst other benefits, for greater precision when riding. The steering pin of the orbital wheel is designed around a second large bearing in the hollow section of the circular runner. Steering is achieved by this inner bearing and the arms that attach the wheel to the main body.
The Motivo features an integrated CPU and organic LED touch screen which allows the rider to customize the scooter to their own preference. Along with this are the features that enable the rider to connect wirelessly to the Internet, to access GPS or an iPod dock to listen to music.
The Motivo design was recently awarded first prize in the transport category of the Create the Future Design Contest .
