Bed with system for propelling the bed including motorized wheel, drive for propelling, processor unit and control member. Using the controller connected via the processor unit to the drive for propelling of the motorized wheel it is possible to change the modes of the motorized wheel. In the first mode the movement of the motorized wheel is dependent on the drive for propelling, whereas in the second mode the motorized wheel rotates independently of the drive for propelling. Using the system for propelling the bed it is thus possible to start the bed moving in the selected direction, in manual mode or in braking mode.
