A three- or four-wheeled amphibian (1) comprises hull (2), body (3), front steered wheel (11) or wheels (11, 11′), and rear wheel (9) or wheels (9, 9′). Each steered wheel is connected to the amphibian by a retractable suspension assembly (10, 10′). Upper and lower suspension arms (14 and 15) have pivotal connections (17) and (18) to inner upright arm (16). Retraction rams (28) are connected to body (3), and can retract the wheels for use on water and protract them for use on land. Wheels (11, 11′) also lean on cornering. The pivotal connections (17, 18) for wheel retraction are also used to facilitate leaning. This may be allowed through rotation of drop link (31) around pivot (32). A motor and gearbox assembly (30) may be attached to body (3) to provide controlled lean when cornering, and to keep the amphibian (1) upright when stationary. Leaning may be powered, or user-initiated. Powered lean correction may be provided.
