There is provided a vehicle comprising a chassis, two surface-engaging front wheels, at least one surface-engaging rear wheel and a propulsion unit for driving either the front wheels or the rear wheel or wheels. Each front wheel being connected to the chassis by means of a front wheel support assembly, wherein the front wheel support assembly comprises a hydraulic cylinder associated with each front wheel. Each hydraulic cylinder comprises a housing connected to one of the chassis and the front wheel support assembly, and a piston connected to the other of the front wheel support assembly and the chassis. The piston is moveable within the housing and arranged to divide the hydraulic cylinder into first and second chambers each having respective ports arranged to allow hydraulic fluid to enter and exit the respective chamber, the ports of the first chambers of each hydraulic cylinder being in fluid communication and the ports of the second chambers of each hydraulic cylinder being in fluid communication such that movement of hydraulic fluid from the first or second chamber of one hydraulic cylinder to the respective first or second chamber of the other hydraulic cylinder displaces the pistons of the hydraulic cylinders in opposing directions relative to the respective housings to enable the vehicle to tilt.
