Hubless front wheels are used to allow for adaptability. In bike-mode, the front tires split and separate slightly to provide more stability and a better longitudinal center of gravity. When in car-mode, the front wheels of each bike move together to form car wheels that are more traditional in terms of width and separation.
The rear wheels are powered by separate electric motors. Roll-axis longitudinal steering is used at both the front and the rear so as to decrease the turning radius and mitigate the limited steering of the front hubless axle.
Vehicle docking and undocking is achieved by the push of a button. The docking connectors are situated towards the front and rear of the docking side of the bikes. An automated docking mechanism with a small landing wheel is used to help stabilize and align the vehicles during the process, much like an auto-parking feature on some of today’s cars.
The idea for the unusual design came from Fast Company’s Mark Wilson, and was distilled into renderings by product design firm Argodesign. Wilson says the aim was to create something that could provide the social experience of a car, but that could be a sporty personal urban transport vehicle too.
