A golf club storage and transport device including: a body sized to receive a plurality of golf clubs , the body having at least one storage compartment disposed on a lower portion thereof; and at least a pair of modular wheel assemblies , each being releasably attachable to the body and each including: an arm defining a proximal end configured for attachment to the body and a distal end having an axel projecting therefrom; a wheel being rotatably mountable to the axel; a port for releasable connection of a power supply; an electric motor disposed upon the arm , the electric motor being driveably coupleable to the wheel; wherein the modular wheel assembly is configured to function, in use, as a self-contained drive unit such that mechanical mounting of one or more of the modular wheel assemblies to the body renders the body mobile, without any requirement for the body to house any components associated with propulsion, power or control; the device having an assembled configuration in which the modular wheel assemblies are attached externally of the body so as to support the body, characterised in that the golf club storage and transport device further includes a motor controller being configured so as to control rotation of the electric motor and to cause a rotational speed differential between the wheel and a wheel of a like modular wheel assembly so as to control the motion of the body to which the modular wheel assembly and the like modular wheel assembly are attached; and in that the golf club storage and transport device has a disassembled configuration in which the modular wheel assemblies are detached and are storable upon an upper portion of the body or in the at least one storage compartment . a body sized to receive a plurality of golf clubs , the body having at least one storage compartment disposed on a lower portion thereof; and at least a pair of modular wheel assemblies , each being releasably attachable to the body and each including: an arm defining a proximal end configured for attachment to the body and a distal end having an axel projecting therefrom; a wheel being rotatably mountable to the axel; a port for releasable connection of a power supply; an electric motor disposed upon the arm , the electric motor being driveably coupleable to the wheel; wherein the modular wheel assembly is configured to function, in use, as a self-contained drive unit such that mechanical mounting of one or more of the modular wheel assemblies to the body renders the body mobile, without any requirement for the body to house any components associated with propulsion, power or control; the device having an assembled configuration in which the modular wheel assemblies are attached externally of the body so as to support the body, characterised in that the golf club storage and transport device further includes a motor controller being configured so as to control rotation of the electric motor and to cause a rotational speed differential between the wheel and a wheel of a like modular wheel assembly so as to control the motion of the body to which the modular wheel assembly and the like modular wheel assembly are attached; and in that the golf club storage and transport device has a disassembled configuration in which the modular wheel assemblies are detached and are storable upon an upper portion of the body or in the at least one storage compartment . <EOS>
