A three wheeled vehicle ( 1 ) has a front section ( 10 ) having a front frame ( 105 ), a directionally controllable front wheel ( 101 ) and a steering column ( 104 ) with a handlebar ( 1040 ). A rear section ( 11 ) has a rear frame ( 107 ) and two rear wheels ( 102,103 ). The front section ( 10 ) of the vehicle is pivotable about a pivot axis ( 111 ) located intermediate the two rear wheels ( 102,103 ). The pivot axis ( 111 ) includes a pivot bar ( 401 ) and a pivot bar housing ( 402 ) in communication with a transmission mechanism having a first and second gear pairs ( 2 ) ( 3 ). The transmission mechanism is releasably connected to the steering column ( 104 ) and is capable of pivoting the first section ( 10 ) about the pivot axis ( 111 ) towards the center-of-curvature of a turn in accordance with the angle of the front wheel ( 101 ), thus providing greater stability for the vehicle ( 1 ) during a turn.
