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.
