Quadro 4D Concept

One of the more interesting concepts that will be shown at the EICMA show in Italy this year are what appears to production-ready prototypes of a new scooter concept from Quadro Technologie, a new arm of Marabese Design. Marabese was the designer for the Piaggio MP3 scooter, but now they’ve gone one step beyond that with a 4-wheeled concept. The video makes it look very interesting.


Essentially, what you have here is a 4-wheeled vehicle, but with each wheel independently suspended, allowing it to lean like any other scooter or motorcycle.  What you get from that combination is a much more sure-footed vehicle, with loads more traction, and more abilioty to take bad road conditions in stride.  At the same time, the ability to lean makes cornering safer by balancing the forces of gravity and inertia–unlike a normal trike, where cornering can be a bit riskier business.

I can certainly see the advantages this offers for a commuter bike.  Keep an eye on this technology.
