A B S T R A C T A 3-wheeled velociman having individual power transmission units 40 to each of the co-axial rear wheels 11, 12. Power to the unit is supplied by a pair of hand actuated levers 50, 51 each of which connects with an input shaft 41 to the respective unit via a ratchet mechanism 55 which transmits the power to the input shaft 41 in the desired rotational direction. The input shaft drives an output shaft 42 on which the corres- ponding rear wheel is mounted. A gear change mechanism provides forward, reverse or neutral action to the input shaft and includes a gear change switch 60 on each hand lever 50, 51, easily operated by the user. The hand levers are fulcrummed to the input shaft below and to the rear of the seat 18 and lie at an acute angle to the horizontal making operation of the levers by the user less tiring on the user's arms than on upright levers.
