[QUAD-L] Super quad lever control wheels, anybody use them?

[Bobbie299]

Hey All,     In my latest issue of SCILife there is an article "Alternative Modes of Manual Wheelchair Propulsion" by Philip Requejo, Ph, D     "...One example is lever-activated gear system designed to provide increased mechanical advantage by virtue of a lever arm attached to a roller mechanism of each hub. The lever shifts between forward and reverse through a shifter located on top of the lever arm. To move forward, the lever is activated by pushing the lever forward. In reverse, the gear is activated by pulling the lever backwards. Breaking is activated by pulling the lever inward. And based upon the strength, ability, and needs of an individual user, a gear ratio ranging from 1:1 (easiest) to 5:1 (hardest) can be installed. The lever-activated gear system adds about six pounds to the wheelchair and the existing wheels can be easily replaced by virtue of a quick disconnection."   Anybody ever heard or seen them or use them, the lever controlled chair?     Bobbie
