Abstract
Abstract Foldable two-wheeled vehicle comprising a frame in which there is provided at least one central body ( 10 ), at least one group ( 20 ) supporting the rear wheel ( 21 ), at least one group ( 60 ) supporting the front wheel ( 61 ) and at least one group ( 50 ) for steering the front wheel ( 61 ), which are respectively hingeably joined to the central body ( 10 ), there being provided means for controlling ( 70 ) and actuating (L 72 ,L 73 ,L 74 , L 75 ,L 76 ) the rotation of groups ( 20,50,60 ) around the central body ( 10 ), so as to close/open the frame from an open configuration suitable for use to a closed configuration suitable for transportation and vice versa.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
108 words
Foldable two-wheeled vehicle having a front and rear wheel comprising: a frame in which there is provided at least one central body; at least a supporting group of the rear wheel; at least a supporting group of the front wheel; at least a steering group for the front wheel, said groups being hingeably joined to the said central body; and a single means for controlling and actuating the rotation of said groups around said central body, so as to automatically and simultaneously cause the correct sequence of displacement of said groups from an open configuration, suitable for use, to a closed configuration suitable for transportation, and vice versa.
Claim 2
Dependent Claim
108 words
Foldable two-wheeled vehicle having a front and rear wheel comprising: a frame in which there is provided at least one central body; at least a supporting group of the rear wheel; at least a supporting group of the front wheel; at least a steering group for the front wheel, said groups being hingeably joined to the said central body; and a single means for controlling and actuating the rotation of said groups around said central body, so as to automatically and simultaneously cause the correct sequence of displacement of said groups from an open configuration, suitable for use, to a closed configuration suitable for transportation, and vice versa.
