Turn your manual Wheelchair into an Electric one with the Wheelchair Roma medical Power Pack, complete with variable speed and reverse. This unit is controlled by the attendant not the user of the wheelchair and is easily removable when not required. The pack benefits from twin drive wheels, an easy to operate hand control lever, a removable battery pack for remote charging and it has a security key switch. Please note: this powerpack is quite heavy, but it has to be to achieve greater traction with the ground. When fully fitted your wheelchair will not fold up, but by using the quick release mechanism, the powerpack can be removed and the wheelchair folded in seconds.
