In his search for the ideal workout for wheelchair-bound people, company founder Larry Pestes was shocked by what he found initially back in the 1980s. Practically nothing. Or worse. Machines that were really just treadmills with tethers for the chair or that placed wheelchairs perilously high on a platform so the wheels could be immobilized. Pestes knew that had to change, so he and a team of engineers developed a special locking system that securely fastens any type of wheelchair to the machine. In essence, the chair and machine become one. No wobbling or tilting, giving you the freedom to focus on your workout.
