An apparatus (10, see fig.1) for transporting a load including: a main body (12); a ground engaging wheel (20a, 20b) positioned at or towards an end (13) of the main body and supported for rotation about a generally horizontal axis A. A motor 30a, 30b supported on or by the main body and within a motor housing 32, the motor being drivingly connected to the wheel to move the apparatus over a ground surface. The motor is an electric motor, wherein the motor includes a rotor brake which is moveable between a braked condition which, when the stator is not electrically powered, prevents the rotor from rotating, and an unbraked condition which, when the stator is not electrically powered, permits the rotor to rotate. The apparatus includes a rotor brake actuation device 50 having a user actuatable member (60, see fig. 6) which is accessible from outside the motor housing 32. The brake actuation device is movable between a braked condition and an unbraked condition. The device may comprise levers 35a, 35b which manually overcome a spring force which biases the rotor brake into engagement with friction material and thus into the unbraked position.
