UDS BIKE PRESENTATION, English version
UDS BIKE PRESENTAZIONE, versione in Italiano - Bicycle / motorbicycle (patented), with a new kind of frame and rear dumping system; the seat rotates around a point that is coincident with the rotating axis of the rear wheel. In this way, the angle of inclination of the fork doesn't change during the dumping. This gives more stability and safety, especially at high speed, in downhill competition, and similar.
