Abstract: Disclosed is an improvement for a wheelchair of the type having a pair of generally parallel support bars, a footrest, and a plurality of footrest supporting wheels. The improvement comprises a crossbar, a center bar, a front wheel post, a front wheel, and a handlebar. Each end of the crossbar is connected to one of the support bars of the wheelchair with a crossbar mounting. The center bar is fixed at one end thereof proximate to a center point of the crossbar and terminates at the other end thereof at a front wheel post support which rotationally captures the front wheel post. A lower end of the front wheel post terminates in a pair of generally parallel fork posts between which the front wheel is axially mounted. A powered driving means rotationally drives the front wheel and is controlled by a throttle mounted on the handlebar. The handlebar is fixedly attached to a handlebar support of an upper end of the front wheel post.
