A pedestrian motorised wheelbarrow having a front axle member mounting two front road-wheels, a back axle member mounting two back road-wheels, an electric motor mounted towards the rear to drive directly the rear two wheels which in turn drive the front two wheels, a carrier for a battery-pack to power the motor arranged for substantially the whole battery-pack weight to be at the front axle member, the empty wheelbarrow having more than half its weight on the front axle member, a hopper such that its load will be mainly on the front axle member, handles for tilting the wheelbarrow to lift the rear wheels off the ground, and a brake operating automatically upon interruption of the motor's power supply; the hopper being pivotally mounted so that, upon sudden braking, it will tend to pivot to eject its load forwards subject to a releasable catch worked from the handle area.
