ABSTRACT:
An electric drive attachment for a wheelchair. The drive includes an electric motor constituting the input member of the drive, a wheel adapted to touch the ground and to drive the wheelchair by frictional contact with the ground, the wheel constituting the output member of said drive and speed-reducing means interposed between the input member and the output member. The input member, the speed-reducing means and the output member are mounted on a common mounting member attachable to the wheelchair, and means are provided to cause the common mounting member to selectively assume a first position in which the output member is in contact with the ground, and at least one second, non-contact position, in which the output member is lifted off the ground.
